Lymphangioma-like Kaposi sarcoma of the oral mucosa

Abstract

With the epidemic of acquired immunodeficiency syndrome, the clinical and histopathological features of Kaposi sarcoma (KS) became routine for most practicing surgical pathologists. The histological spectrum of KS broadened significantly over time and today a wide variety of rare histological variants are reported, but not widely recognized. Lymphangioma-like KS (LLKS) is a rare histological variant of KS occurring in skin, with banal histological features that can lead to misdiagnosis and inappropriate therapy. We report a series of intra-oral cases of LLKS and review the literature regarding this lesion.
