fa Microscopic diversity in oral Kaposi sarcoma پاتولوزی دهان، فک و صورت Oral and Maxillofacial Pathology پژوهشي Research Kaposi sarcoma is the most common HIV-associated neoplasm, frequently presenting with oral mucosal involvement. This retrospective study aimed to assess and highlight the histomorphological spectrum of oral Kaposi sarcoma. A total of 135 cases diagnosed between 1990 and 2011 were retrieved from the archives of the Oral and Dental Hospital of the University of Pretoria, South Africa. Following histologic review, each case was placed into 1 of 7 categories based on the predominant pattern of growth. These histologic divisions included lesions designated as solid, lymphangioma-like, telangiectatic, desmoplastic, lymphangiectatic, ecchymotic, and anaplastic. The presence of coexistent pathology was identified in 25 cases, largely represented by superimposed candidiasis. Concomitant cytomegalovirus and non-necrotizing granulomatous inflammation were also observed. Although the prognostic significance of these variants is yet to be determined, the appreciation and recognition of such morphologic diversity remains essential in distinguishing these lesions from possible mimickers. <hr><p> <strong>Source: </strong>Oral Surgery, Oral Medicine, Oral Pathology, Oral Radiology </p><p> Full Text</p> 0 0 http://idai.ir/browse.php?a_code=A-10-32-1531&slc_lang=fa&sid=1 Belinda K.Bunn 10031947532846007036 10031947532846007036 No Department of Oral Pathology and Oral Biology, School of Dentistry, Faculty of Health Sciences, University of Pretoria, South Africa Marianne de Vasconcelos Carvalho 10031947532846007037 10031947532846007037 No Department of Oral Diagnosis, Piracicaba Dental School, State University of Campinas, Brazil Melanie Louw 10031947532846007038 10031947532846007038 No Department of Anatomical Pathology, School of Medicine, Faculty of Health Sciences, University of Pretoria, South Africa Pablo A.
