The condition has been misdiagnosed by two dermatologists as actinic lichen planus for 5 months.

Kaposi sarcoma (KS) is the commonest tumour in patients infected with HIV. It is an AIDS-defining illness and is caused by a γ herpesvirus, the Kaposi sarcoma herpesvirus (KSHV), also called Human Herpesvirus-8 (HHV-8).

It is recommended that KS should be confirmed histopathologically (healing of the biopsy site). 

Histopathological clues to Kaposi's sarcoma:

• Abnormal tissue spaces in the dermis
Promontory sign (small vessel protruding into an abnormal space)
Haemosiderin and plasma cells
Stuffing of all dilated neoplastic vessels with red blood corpuscles in the absence of plasma
• Established lesions have the usually documented features.
