Malignant lymphoma (ML) is one of the major issues in modern medical practice, with an increasing incidence in recent years, which makes it, together with leukemia, the most frequent form of neoplasia affecting young people. The onset can occur both inside and outside the lymph nodes, with a quarter of the lymphomas with extranodal onset being located in the head and neck. The purpose of the paper is to conduct a retrospective study over a period of six years on patients diagnosed and admitted to the clinic with malignant lymphomas located in the head and neck, discussing their different histological variations. It emphasizes the importance of the histopathological examination and, in particular, of the immunohistochemical tests, in determining the histological subtype of the lymphoma, as the immunohistochemical and cytogenetic data of the malignant cell play a major role in the evolution and prognosis of patients. The study leads to the conclusion that, in spite of the advancements of the immunological, cytogenetic and molecular techniques, the diagnosis and histological determination of malignant lymphomas continue to be a challenge to clinicians and anatomical pathologists. Of particular importance in the efforts made for the accurate diagnosis and proper treatment of the ENT (ear, nose and throat) malignant lymphomas is the interdisciplinary collaboration between the ENT specialist, the hematologist, the anatomical pathologist, the oncologist and the nutritionist.

The eyelids represent a frequent site for numerous malignant tumors, which generally present subtle symptoms or can imitate benignant tumors. Our study was carried on 80 patients, 48 males and 32 females aged between 48 and 92 years. The patients were hospitalized in the Ophthalmology Clinic of the Emergency County Hospital of Craiova, Romania. The study was conducted over five years, between 2010 and 2014. Our study included 80 basal cell carcinomas of the eyelids, of which 48 (60%) were nodular basal cell carcinomas, 15 (18.75%) were adenoid basal cell carcinomas, 10 (12.5%) were cystic and seven (8.75%) were morpheaform basal cell carcinoma. Our study showed a moderate expression of bcl-2 marker in the nodular type of basal cell carcinoma and a high expression in the other histopathological types, thus inducing an increased malignancy comparing to the nodular type. E-cadherin was absent in nodular, cystic and adenoid basal cell carcinomas and had a moderate expression in morpheaform basal cell carcinoma. Morpheaform and adenoid types presented 20% expression of Ki67 of the malignant cells nuclei, while the cystic type presented Ki67 expression in less than 10% of the malignant cells nuclei. Due to high morbidity and increasing incidence, basal cell carcinoma of the eyelid represents an important health issue nowadays.
