Multi-organ involvement of bacillary angiomatosis masquerading as Kaposi sarcoma and pyogenic granuloma: A case report and literature review

Abstract

Bacillary angiomatosis is a vasoproliferative neoplasm primarily seen in immunocompromised individuals. There are overlapping clinical and histopathologic manifestations of bacillary angiomatosis, Kaposi sarcoma, and pyogenic granuloma. Distinguishing an accurate diagnosis between these entities utilizing clinical, histopathologic, and molecular analysis becomes significant as prognosis and treatment differ. Here, we describe a case of bacillary angiomatosis masquerading as a Kaposi sarcoma and pyogenic granuloma and also highlight unusual presentations and the diagnostic approach to this entity.
