ABSTRACT: Patients infected with human immunodeficiency virus frequently manifest with rare infections as well as neoplasms. We report an unusual and interesting case of an intranodal Kaposi's sarcoma (KS) with coexistent/concurrent granulomatous lymphadenitis secondary to atypical mycobacteria in a groin lymph node. "Mycobacterium pseudotumor" is a nonneoplastic condition and should be distinguished from true KS as these 2 entities differ in their prognosis and treatment. In this article, we discuss the diagnosis and differential diagnosis of this exceptional clinical and pathologic manifestation.
