Abstract

An old borderline-lepromatous leprosy patient, treated initially with DDS monotherapy followed by MDT, 11 years later during surveillance presented with 3-month-old asymptomatic cystic swelling, arising from the right ulnar nerve without exhibiting any evidence to document relapse of the disease. It responded promptly to corticosteroid therapy. This unusual clinical presentations of ulnar nerve abscess has not been reported elsewhere.
