An unexpected host in a soft-tissue lesion of thigh

Indian J Med Microbiol. 2020 Jul-Dec;38(3 & 4):478-480. doi: 10.4103/ijmm.IJMM_20_236.

Abstract

Rhinosporidiosis is an enigmatic entity and poses a major health problem in the developing countries of South-East Asia. A soft friable polypoid nasal mass is the most common presentation, while sparse literature is available on extranasal involvement. We describe the case of a 35-year-old female patient who presented with a slow-growing soft-tissue swelling with ulceration over the thigh. On clinical and radiological examination, a provisional diagnosis of soft-tissue neoplasm was made. After resection, histopathological sections showed a closely packed cyst with innumerable endospores. The present case report documents the rare occurrence of an incidentally detected cutaneous rhinosporidiosis causing diagnostic difficulty.

Keywords: Histopathology; rhinosporidiosis; soft-tissue swelling.
