Introduction
Kaposi sarcoma (KS) is a rare borderline angioproliferative disorder
characterized by multiple vascular mucosal or cutaneous lesions.1
It has four major types: classic (predominantly in elderly men) (CKS),
African endemic (AEKS), immunosuppression associated or
transplant-associated (ITKS) and AIDS-associated. 2,3
The classic form typically presents with cutaneous lesions on the lower
extremities. 1 While the head and neck is a common
site for mucocutaneous lesions in HIV patients with KS, the presence of
lesions on the head and neck in HIV negative patients is a rare
phenomenon. 4,5
Among the reported cases of Kaposi sarcoma auricular involvement is very
rare. In a study of 11 KS cases presented on head and neck, though the
majority of cases were HIV-positive, the 2 patients with KS lesions on
their external ears were both HIV-negative. Therefore, they highlighted
the importance of considering KS as a differential diagnosis for
vascular lesions on the ears of HIV-negative patients.6 This study aims to present a case of HIV-negative
patient with multiple recurrent papules on his ear diagnosed as Kaposi
sarcoma that developed KS lesions on his foot years later with a review
of literature on KS presented on ears (table 1).
