Abstract

Hyalohyphomycosis are opportunistic fungal infections caused by saprobic fungi. Such mycoses usually occur in immunosuppressed patients. The most affected organ is usually the lungs. A male patient has arrived at the Orthopedics and Traumatology Service complaining of a mass on the dorsal surface of his right foot. On physical examination, a subcutaneous, elastic, non-mobile mass was observed on the dorsal surface of the right foot. Ulcerated lesion, without drainage of secretion and with pain on palpation. He reported focal increase in the dorsal surface of the right foot for 7 years. Among other diagnostic possibilities, imaging studies indicated the hypothesis of a giant cell tumor with a tendon sheath. The patient was then submitted to biopsy of the lesion. The anatomopathological study showed chronic suppurative inflammation with granulation tissue and the presence of septate hyaline hyphae compatible with hyalohyphomycosis. Surgical resection of the lesion and systemic treatment were then performed. Patient evolved well after the procedure.
