An unusual presentation of sporotrichosis

Abstract

Sporotrichosis can mimic a few diseases. Sporotrichosis presenting as a hypoaesthetic plaque or plaque suggestive of leprosy has not been mentioned in literature. Herein we present a case of a 26 years old man who presented with hypoesthetic plaque on left ankle and was clinically diagnosed to have borderline tuberculoid leprosy who later developed few nodules in linear fashion on left leg, which ruptured to form non healing ulcers. Culture from ulcer grew Sporothrix schenckii. Patient was successfully treated with oral potassium iodide.

Keywords: Leprosy; oral potassium iodide; sporotrichosis.
