Cutaneous Coccidiomycosis Masquerading as an Epidermoid Cyst: Case Report and Review of the Literature.

Objectives: To present a challenging case of inoculatory fungal mycosis mimicking an epidermoid cyst, which may have been easily overlooked by the pathologist.

Methods: We present a case report of a 29-year-old male with a nodule on the right lower back, which was surgically excised and submitted to pathology as a ruptured epidermoid cyst.

Results: Histopathologic sections revealed detached soft tissue fragments containing polymorphic granulomas with abscess and suspicious-appearing spherical structures ranging in size from 50 to 200 μm.
