A 55-year-old woman presented with a gradually increasing painful forearm swelling since 1 year [Figure 1]. Physical examination revealed a cystic tender mass measuring 3.5 × 3 × 2.5 cm. The mass was mobile and distinct from surrounding structures. The cyst was excised with a probable clinical diagnosis of sebaceous cyst.

On gross examination, the cyst was smooth surfaced and measured 3.5 cm in diameter. On opening the cyst was filled with yellowish material. Histopathology revealed a fibrocollagenous cyst wall [Figure 2] lined by well formed granulomas composed of multinucleated Langhan's as well as foreign-body type of giant cells and histiocytes admixed with dark brown yeast forms [Figure 3]. Few septate branched periodic acid schiff positive fungal hyphae were seen within the giant cells.
