Recurrent Classical Type of Kaposi's Sarcoma Treated by Interferon-alpha

Min Ju Kang et al. Ann Dermatol. 2008 Sep.

Abstract

Kaposi's sarcoma (KS) is a lympho-angioproliferative disease, with four variants; one of which is classical KS (CKS). Classical KS is clinically characterized by single or multiple pea-sized bluish-red macules on the distal portions of the lower extremities. A 60-year-old man presented with an asymptomatic, solitary patch on the left sole. He had been successfully treated for the classical type of Kaposi sarcoma on the right sole with interferon-alpha 3 years before. The patient was treated with six million units of interferon-alpha three times per week for 6 months. The lesion showed complete resolution and there has been no report of recurrence for 1 year after treatment.

Keywords: Interferon-alpha; Kaposi's sarcoma.

Fig. 1. (A) First visit - mildly tender, erythematous, 1.2 cm sized nodule and satellite purplish macules and papules are observed on the sole. (B) Second visit - an asymptomatic, solitary, purplish patch is seen on the left sole. (C) Spindle cells forming slit-like spaces occupied by red blood cells and endothelial proliferation in the dermis (H&E stain, ×40; inlet, ×200). This histopathologic characteristic was found in both A and B lesions
