Abstract

The acquired immunodeficiency syndrome (AIDS) is caused by the human immunodeficiency virus (HIV). The infection has affected more than 60 million people around the world and over 25 million deaths. Despite the progress of the international community, AIDS is still a global epidemic and is a considerable public health problem worldwide. Due to this, this work is based on the approach of the manifestations of AIDS patients, focusing to two relatively distinct topics, but too much relevant. The first description is based on the unpublished morphological diversity oral Kaposi's sarcoma (OKS), which is one of the most common HIV manifestations, with frequent oral involvement. We performed a retrospective study of 135 cases of OKS retrieved from the archives of the University Of Pretoria, South Africa. After histological review, the OKSs were classified into 7 categories based on the predominant pattern of growth, such as solid, lymphangioma-like, telangiectatic, desmoplastic, lymphangiectatic, ecchymotic, and anaplastic. 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. Regarding the second chapter, we analyzed 100 thyroid obtained from autopsies of patients with AIDS, Department of Pathology, Faculty of Medicine, University of São Paulo. The cases were systematically analyzed in order to determine the frequency and the main pathological features of the gland. Mycobacteriosis infection was the most frequent, followed by cytomegalovirus (CMV) and cryptococcosis. Involvement of the thyroid gland usually occurred as a part of dissemination of the disease. Physicians should pay special attention to the early signs of thyroid disease, which can be misdiagnosed with symptoms of general manifestations of AIDS (AU)
