There is no doubt that the association between infection of the cervical epithelium by carcinogenic Human Papilloma Virus (HPV), particularly types 16 and 18, and cervical cancer (CC) is responsible for the activation of the immune response (IR). Research on tumor infiltrating lymphocytes at the primary tumor site could give us important information on how the immune cells are fighting against cancer. Aim: The aims of our study were to assess HPV status and to evaluate the significance of in situ cellular IR in CC. Materials and Methods: We performed a two-step retrospective analysis of IR in 18 CC: evaluation of HPV 16 and 18 infections by in situ hybridization and immune biomarkers (CD20, CD3, CD45) by immunohistochemistry. Immune cell profile, densities (assigned scores 0 if no inflammatory infiltrate, 1+ low, 2+ intense), tissue distribution and classical negative prognosis factors in relationship with survival and relapse were further assessed. Results: We successfully demonstrated HPV 16 and/or 18 in all cases. We reported statistical significant correlations (p<0.005) between CD3, CD20, CD45 and survival (r=0.800), relapse (r=-0.892), clinical stage (r=-0.914), tumor size (r=-1) as well as the association between survival and CC subtype (r=0.548), FIGO stage (r=-0.914), tumor size (r=-0.800) and grading (r=0.61). Conclusions: The density of different immune cells is significantly involved in guiding prognosis of the CC in high-risk 16 and 18 HPV positive women; low cellular densities for CD3, CD20 and CD45 meaning limited immune response reflect negative disease outcomes promoting local relapse and decreased survival in such settings._x000D_

Background: Parapsoriasis represents a group of cutaneous disorders that shows variable clinical aspects somehow resembling to psoriasis, how is reflecting by its name. It was first named by Brocq, in 1902, as an entity with three components: pityriasis lichenoides, small plaque parapsoriasis and large plaque parapsoriasis. Nowadays, under the name of parapsoriasis are included only the last two categories, that are considered disorders characterized by the presence of a mononuclear infiltrate in the dermis, composed of T-cells. Until now, there were not established pathognomonic histopathological features to diagnose parapsoriasis. Aim: The aim of the study was to investigate the epidemiological and morphological data of parapsoriasis cases diagnosed at Emergency City Hospital, Timisoara, Romania for a period of 12 years. Materials and Methods: The study had two parts; one was retrospective and another one prospective. For the retrospective part, we searched 210111 patient files recorded in our Pathology Service for a period of 11 years, from January 2002 to December 2012. The slides were searched from the archive and re-read by two individual pathologists. For prospective part of the study, we reviewed 11815 histological slides read between January and June 2013. After inspection of the recorded files, the pathologists noted, were available, the localization and number of the lesions, together with symptoms. The biopsied specimens were initially processed with routine histological technique, the archive slides being stained with Hematoxylin and Eosin. While reading the slides, the pathologists paid attention to the architecture of the epidermis, the presence of epidermotropism and interface dermatitis, type of the dermal infiltrate and its distributions. Conclusions: In the present study, we emphasized the histopathological aspects of parapsoriasis in order to create a basic line that could help in the establishment of a uniformly accepted definition of parapsoriasis on histopathological grounds.
