Peripheral nerve sheath tumors are a group of neoplasms that arise from Schwann cells. This study evaluates the histopathological and immunohistochemical (IHC) characteristics of these entities, spanning a spectrum from benign to malignant lesions. We focused on tumor variants, particularities, and differential diagnoses. A total of 25 cases were analyzed, with conventional schwannomas being the most common benign tumor subtype. Classic schwannomas exhibited typical Antoni A and Antoni B patterns, with Verocay bodies as defining features. Additionally, less common variants, such as cystic and myxoid schwannomas, were identified, highlighting the morphological variations of these entities. Malignant peripheral nerve sheath tumors (MPNSTs), representing the malignant counterpart, were characterized by spindle cell and epithelioid morphologies, high mitotic activity, and aggressive clinical behavior. Differentiating MPNSTs from other soft tissue tumors, such as neurofibromas and melanomas, was challenging due to overlapping histological features. IHC markers, particularly S100 and sex determining region Y (SRY)-box transcription factor 10 (SOX10), played an important role in the diagnostic process, though their interpretation required precision to avoid diagnostic pitfalls. This study highlights the importance of integrating histopathology and immunohistochemistry for accurate diagnosis and differentiation of peripheral nerve sheath tumors. The recognition of rare variants and analysis of tumor subtypes contribute to a better understanding of these entities, which is crucial for appropriate clinical management.

While ectopic thyroid is an uncommon congenital condition, the occurrence of malignant transformation within ectopic lingual thyroid tissue is exceptionally atypical. We report a rare case of not otherwise specified (NOS) thyroid carcinoma (TC) arising in a sublingual ectopic thyroid in a 54-year-old male. The patient presented with progressive dysphonia, dysphagia, and upper airway obstruction, accompanied by severe hypothyroidism. Imaging studies, including ultrasonography, thyroid scintigraphy with technetium-99m pertechnetate, and cross-sectional computed tomography (CT), confirmed the absence of orthotopic thyroid tissue, identifying a highly vascularized sublingual tumor. Preoperative selective arterial embolization was performed to minimize intraoperative bleeding, followed by a successful surgical excision of the described mass. Histopathological analysis revealed NOS carcinoma arising in ectopic lingual thyroid tissue. The patient was subsequently maintained on suppressive Levothyroxine therapy and referred for radioiodine treatment. This case highlights the importance of a multidisciplinary diagnostic and therapeutic approach in the treatment of ectopic lingual TC. To our knowledge this is one of the few cases of NOS TC arising in a lingual thyroid gland.

3. Morphological properties of bone cement mixed with antibiotics
Danica Popovska, Ivan Boev, Maja Ristova Delipetrev, Alan Andonovski, Slavcho Stojmenski
The aim of this study was to examine the morphology of poly(methyl methacrylate) bone cement manually loaded with meropenem and vancomycin, in order to determine the structural changes in the polymer matrix that occur with antibiotic addition, as well as the relationship between antibiotic particles and the matrix and the changes that occur with cement aging. Samples of SmartSet Endurance(TM) MV bone cement manually mixed with meropenem, vancomycin and their combinations were examined with scanning electron microscopy after 24 hours storage at room temperature in air and after 28 days of incubation in Ringer s solution at 37 degrees C. Manually prepared bone cement was characterized with microporosity of up to 65 micrometers and homogenous polymer structure that does not change significantly with incubation of 28 days. Incubation causes changes in mechanical properties that result with more pronounced cracking of the parts subjected to bending stress. Adding vancomycin causes increase in cement porosity and irregularity in shape and size of pores, not only by creation of antibiotic-filled voids, but also by interference with polymer formation and creation of microporosity areas. Incubation of 28 days causes release of antibiotic particles almost completely from the surface of the sample and less towards the center, with more meropenem particles being released compared to vancomycin.

4. Evaluation of the functional profile of bronchopulmonary cancer patients based on biomarkers in relation to the International Classification of Functioning, Disability and Health
Tania-Ioana Goncea, Mara Amalia Balteanu, Angela-Stefania Marghescu, Beatrice Mahler, Magdalena Rodica Traistaru
Patients with lung cancer commonly report a broad spectrum of symptoms driven by both side effects of treatment and aggressive progression of disease. As a result, growing evidence indicates that pulmonary rehabilitation (PR) can meaningfully improve exercise performance, health-related quality of life (QoL), fatigue, and dyspnea. The core objective of any PR program is to improve the patient s overall functional profile. In this study conducted at the Marius Nasta Institute of Pneumophthisiology, Bucharest, Romania, we assessed the functional profile of patients with non-small cell lung cancer (NSCLC) - specifically lung adenocarcinoma (LUAD) and squamous cell carcinoma (SCC) - and explored its relationship with key biomarkers: programmed death-ligand 1 (PD-L1), anaplastic lymphoma kinase (ALK), and epidermal growth factor receptor (EGFR). Functional status was evaluated using the International Classification of Functioning, Disability, and Health-Rehabilitation Core Set (ICF-RCS). Exercise capacity was measured with the 6-Minute Walk Distance (6MWD) test, health-related QoL was evaluated using the validated European Organization for the Research and Treatment of Cancer Core Quality of Life 30-item Questionnaire (EORTC QLQ-C30) questionnaire and anxiety levels were assessed with the Generalized Anxiety Disorder 7-item (GAD-7) instrument. The study identified a correlation between the patients functional profiles and specific biomarker patterns. Based on these findings, we believe that incorporating biomarker information into functional evaluation could help build a clearer and more clinically relevant understanding of patient needs during PR, ultimately contributing to more personalized comprehensive care. We propose that future research should examine whether the relationship between biomarker status and functional, psychological, and QoL outcomes remains consistent following a structured rehabilitation program, and whether these biological markers can predict which patients are most likely to experience functional and emotional improvements. Such insight could prove valuable in guiding individualized rehabilitation strategies for patients with NSCLC.

6. Post-COVID-19 incidentally discovered adrenal findings (a CT-focused real-life study)
Mihai Costachescu, Anda Simona Dumitrascu, Oana-Claudia Sima, Nina Ionovici, Dana Cristina Terzea, Emi Marinela Preda, Mara Carsote
Background: Coronavirus disease 2019 (COVID-19) pandemic was associated with unexpected endocrine findings at imaging evaluation, including adrenal incidentalomas. Aim: To analyze adrenal findings at computed tomography (CT) in patients who underwent an abdominal and/or thoracic CT scan for non-adrenal conditions and had a positive COVID-19 testing within six to 12 months before. Methods: This was a retrospective, real-life study in adults. Results: Two groups [group C (positive COVID-19 infection; N=46 patients) vs. group non-C (prior negative infection; N=74 patients)] had similar age: 57.72+/-14.23 vs. 53.74+/-13.90 years (p=0.134). 73.33% of patients of group C had abnormal adrenal features similar to 66.22% of patients in non-C. Prevalence of adrenal nodules (ANs) was statistically significantly higher in group C (54.35%) vs. non-C (33.78%) (p=0.026). Detection rate of unilateral AN (45.65% vs. 25.67%; p=0.029) was also higher. 41.67% of entire group (N=120) displayed an AN (group AN), while 58.33% were nodule-free (group non-AN), with similar age and gender distribution. The number of patients with a history of COVID-19 infection was statistically significantly higher in group AN vs. non-AN (50% vs. 30%; p=0.026). Multivariate logistic regression analysis explained 17.5% of the variance (R2: 0.175). After adjusting for age, gender, right unilateral hyperplasia and left unilateral hyperplasia, the presence of the COVID-19 history remained statistically significantly (p=0.028) associated with increased odds of having an AN [odds ratio (OR: 2.471, 95% confidence interval (CI): 1.105–5.527]. A statistically significant correlation was found between the age and the largest diameter of AN within group AN (r=0.387, p=0.009). Conclusions: Awareness remains the key factor in the CT-detected lesions that have been identified after prior coronavirus infection, some being a direct consequence, while others are incidental elements.

Background/Objectives: While uterine leiomyomas are one of the most common pathologies encountered in gynecology, myomas arising from the vagina are rarely identified and a limited number of cases have been reported so far. With variable locations, diagnosis and surgical treatment of the vaginal leiomyoma can be challenging. Case presentations: We present two cases of vaginal myomas. The first case was of a 43-year-old patient who presented dyspareunia. Clinical examination revealed a vaginal mass, of 2/1 cm, located on the posterolateral left vaginal wall. Ultrasound showed a well confined, hyperechogenic round mass. After vaginal excision and histopathological analysis, the final diagnosis was established - vaginal leiomyoma. The second patient presented it for a routine gynecological examination. A firm nodule was palpated in the posterior vaginal fornix. After transvaginal excision, the diagnosis was histopathologically confirmed - vaginal myoma. Conclusions: Whenever confronted with a vaginal mass, the diagnosis of a vaginal myoma should be kept in mind, as transvaginal excision is the preferred surgical treatment.

Cristian Barsu, Anne-Marie Constantin, Andrei Picos
The Romanian School of Pathology has a complex history, which must be thoroughly known to be appreciated at its value. The research includes data on the pathology evolution in our country, the overview of the most important research centers and their dealings. It also contains landmarks about the most important Romanian pathologists, their activities etc. Among them was Augustin Muresan (1908-1985). He was member of three important Romanian pathology centers: Cluj, Bucharest and Timisoara. Cluj was the place of his career debut and the place where he ended his professional activity. In Bucharest, his professional training and career took place over two decades. In Timisoara, he taught pathology courses for students for two years. Among his professional achievements, it should be noted that under his editorship was published the unique textbook of pathology for Romanian faculties of medicine (1962). He also supervised doctoral theses for more than 20 years. He described the first three cases of histoplasmosis in Romania, and he was one of the first Romanian researchers who studied liver biopsies (1942) and kidney biopsies (1947).

Christiana Raluca Danciulescu, Constantin Renato Ivanescu, Daniel-Robert Stanescu, Andrei-Florentin Baiasu, Dragos Ovidiu Alexandru, Mircea-Sebastian Serbanescu
Background: Accurate detection of coronary artery disease (CAD) from cardiac magnetic resonance (CMR) imaging can support earlier diagnosis and streamlined clinical decision-making. Objective: This study evaluated the performance and statistical robustness of two deep learning architectures - DenseNet121 and ResNet50 - for automated CAD classification using multiparametric CMR imaging. Methods: Images were preprocessed using a valid pipeline and partitioned strictly at the patient level. Model performance was quantified through average accuracy, area under the receiver operating characteristic (ROC) curve (AUC-ROC), precision recall, while distributional assumptions were assessed using Shapiro-Wilk tests and variance homogeneity was explored with Brown-Forsythe test. Results: ResNet50 demonstrated the strongest performance, achieving an average accuracy of 90.43%, AUC-ROC of 0.862, and area under the precision recall curve (PR-AUC) of 0.891. DenseNet121 showed lower accuracy (81.72%). Statistical analysis revealed non-normal performance distributions and significant variance differences between models. Conclusions: The findings indicate that ResNet50 offers a reliable and statistically validated solution for CAD detection from CMR imaging. The combined use of realistic preprocessing and comprehensive inferential testing supports the generation of reproducible and clinically meaningful performance estimates.

10. Immunoexpression of Cyclin D1, P53 and Ki67 in prostatic acinar adenocarcinomas
Adrian Mihai Stoiculescu, Oana Iulia Cretu, Bianca Catalina Andreiana, Dan Stefan Diaconescu, Petru Octavian Dragoescu, Alex Emilian Stepan
Prostate cancer continues to be a health problem by epidemiological indicators, despite prevention and detection programs and advanced knowledge of molecular biology. Acinar forms are the most common and constitute a tumor group with a relatively good prognosis, but sometimes unpredictable compared to the associated histopathological (HP) parameters. Among the molecular mechanisms involved in tumor cell proliferation is the disruption of the cell cycle, and the evaluation of the expression of key proteins involved can assist the histological stratification of cases. The study investigated the immunoexpression of Cyclin D1, P53 and Ki67 in 55 prostatic acinar adenocarcinomas (PAAs), in relation to the HP prognostic parameters of the lesions. High reaction scores expressed as positivity index (PI) indicated the significant association of the three markers with increased grading groups recommended by International Society of Urological Pathology (ISUP), perineural and lymphovascular invasion. P53 PI and Ki67 PI were significantly or at the limit of significance increased in conventional and colloidal PAA, and in the case of P53 and in addition in advanced stages. Analysis of the effective values of the reactions indicated significant positive linear correlations between the investigated immunomarkers. The reactions were variable in a relatively homogeneous group of PAA and although they were generally associated with aggressive HP behavior, they seem useful in the punctual identification of cases that require a particular management, in the context of specific oncological therapy.

Acute abdominal emergencies remain a leading cause of mortality in the emergency setting, often resulting in death before surgical intervention can be performed. During the coronavirus disease 2019 (COVID-19) pandemic, these cases were further complicated by thrombotic and inflammatory mechanisms, with a notable increase in mesenteric ischemia. We conducted a retrospective monocentric study of 31 postmortem cases of acute abdomen occurring between January 1, 2019, and December 31, 2023, analyzing demographic characteristics, clinical presentation, laboratory parameters, imaging, and autopsy findings. Among 69 total deaths in the Emergency Department during this period, 31 were attributed to acute abdominal pathology, the majority involving elderly, septic patients with perforation or ischemia. Nine deaths from mesenteric ischemia occurred during the COVID-19 period, emphasizing severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)-associated hypercoagulability. Other fatal cases included perforated ulcers, ruptured hepatic or pancreatic tumors, and advanced neoplasms with secondary peritonitis. Laboratory markers such as elevated lactate, leukocytosis, and coagulopathy corresponded with postmortem evidence of intestinal necrosis, thrombosis, or peritoneal contamination. Although urban patients predominated, rural patients frequently presented with advanced sepsis at admission. These findings highlight that acute abdominal emergencies carry high mortality and underscore the critical importance of early recognition, rapid triage, and multidisciplinary management. Postmortem analysis provides essential insights into fatal mechanisms and supports the refinement of diagnostic and treatment protocols to improve outcomes.

The study investigated the immunoexpression of Cyclin D1, P53 and Ki67 in 55 prostatic acinar adenocarcinomas (PAAs), in relation to the HP prognostic parameters of the lesions. High reaction scores expressed as positivity index (PI) indicated the significant association of the three markers with increased grading groups recommended by International Society of Urological Pathology (ISUP), perineural and lymphovascular invasion. P53 PI and Ki67 PI were significantly or at the limit of significance increased in conventional and colloidal PAA, and in the case of P53 and in addition in advanced stages. Analysis of the effective values of the reactions indicated significant positive linear correlations between the investigated immunomarkers. The reactions were variable in a relatively homogeneous group of PAA and although they were generally associated with aggressive HP behavior, they seem useful in the punctual identification of cases that require a particular management, in the context of specific oncological therapy.

Acute abdominal emergencies remain a leading cause of mortality in the emergency setting, often resulting in death before surgical intervention can be performed. During the coronavirus disease 2019 (COVID-19) pandemic, these cases were further complicated by thrombotic and inflammatory mechanisms, with a notable increase in mesenteric ischemia. We conducted a retrospective monocentric study of 31 postmortem cases of acute abdomen occurring between January 1, 2019, and December 31, 2023, analyzing demographic characteristics, clinical presentation, laboratory parameters, imaging, and autopsy findings. Among 69 total deaths in the Emergency Department during this period, 31 were attributed to acute abdominal pathology, the majority involving elderly, septic patients with perforation or ischemia. Nine deaths from mesenteric ischemia occurred during the COVID-19 period, emphasizing severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)-associated hypercoagulability. Other fatal cases included perforated ulcers, ruptured hepatic or pancreatic tumors, and advanced neoplasms with secondary peritonitis. Laboratory markers such as elevated lactate, leukocytosis, and coagulopathy corresponded with postmortem evidence of intestinal necrosis, thrombosis, or peritoneal contamination. Although urban patients predominated, rural patients frequently presented with advanced sepsis at admission. These findings highlight that acute abdominal emergencies carry high mortality and underscore the critical importance of early recognition, rapid triage, and multidisciplinary management. Postmortem analysis provides essential insights into fatal mechanisms and supports the refinement of diagnostic and treatment protocols to improve outcomes.
