Abstract

Abstract: Kaposi's sarcoma is an uncommon, vascular neoplasm associated with Human Herpes Virus 8 (HHV-8). An unusual case of PT-KS, presenting with pain from bilateral macular lesions on the palate, is discussed. As far as the authors are aware, this is the only reported case of a macular post-transplant Kaposi's sarcoma initially presenting with pain. The diagnosis, clinical presentation and histology are discussed, and an update on the oral presentation and management of post-transplant Kaposi's sarcoma is provided.

CPD/Clinical Relevance: Post-transplant Kaposi's sarcoma is a neoplasm found in post-transplant patients that can present intra-orally, and needs to be identified early to ensure the best possible outcome for the patient.

Article

Kaposi's sarcoma (KS) is an uncommon, vascular neoplasm associated with Human Herpes Virus 8 (HHV-8). It arises from lymphatic endothelium-derived cells. There are four defined types − the ‘classical’ sporadic type first described by Kaposi, the ‘endemic’ type found in sub-Saharan African populations, ‘HIV/AIDS Associated’ and ‘Iatrogenic’ found in people who are immunosuppressed through medication (such as those seen in post-transplant patients).1 The first Post-Transplant Kaposi's Sarcoma (PT-KS) was noted in 1969 in a kidney-transplant recipient.2 Kaposi's sarcoma can appear in three clinical forms, based upon the distribution of KS in different systems:3

Prior to the AIDS epidemic and the large increase in organ transplantation, KS was rare, comprising around 0.02−0.06% of malignancies.3

PT-KS in the oral cavity classically presents as a painless, macular red patch or swelling.

An unusual case of PT-KS is presented, with pain from bilateral lesions on the palate.
