Cerebral phaeohyphomycosis (CP) is a very rare but serious form of central nervous system fungal infection that is caused by dematiaceous fungi. It is commonly associated with poor prognosis irrespective of the immune status of the patient. In this study, the authors describe the first case of CP in Korea that occurred in a 75-year-old man without immunodeficiency and showed favorable outcome after surgical excision and antifungal therapy. In addition, the authors herein review the literature regarding characteristics of this rare clinical entity with previously reported cases.

Summary Phaeohyphomycosis refers to a heterogenous group of mycotic infections caused by dematiaceous fungi where unintentional traumatic inoculation accounts for majority of the cases. Herein, we are reporting a rare case of iatrogenic subcutaneous phaeohyphomycosis which is secondary to intravenous cannula placement.

Corynespora cassiicola is a common plant pathogen responsible for leaf-spotting diseases in the tropical and subtropical areas. C. cassiicola seldom causes human infections. Here we describe a case of subcutaneous phaeohyphomycosis caused by C. cassiicola in a 76-year-old Chinese man, who presented to our hospital with a purulent discharge and painful sensation on his right leg. Skin biopsy revealed an abscess, and culture confirmed C. cassiicola to be the causative agent. The result was further identified by sequence analysis of the internal transcribed spacer region. The patient was successfully treated with systemic voriconazole and wound debridement: the lesion disappeared after 20 days.

Phaeohyphomycosis is a subcutaneous and systemic infection caused by dark-walled hyphae and differs from chromoblastomycosis in that it has no sclerotic cells. It commonly occurs in a immunosuppressed host. Exophiala dermatitidis, common pathogen of phaeohyphomycosis, has been commonly reported in Japan, but very rare in Korea. This report describes a case of phaeohyphomycosis due to Exophiala dermatitidis successfully treated with itraconazole.

A case of cutaneous lesions on the left lower leg caused by Curvularia species in an 80-year-old immunocompetent woman is described in this report. The etiological agent was identified as Curvularia species based on its colonial and microscopic morphology in pure tissue culture. The lesions healed after a 9-week regimen of oral itraconazole and topical lanoconazole.

Phaeohyphomycosis refers to subcutaneous and systemic fungal infections characterized by dematiacious septate mycerial elements in tissue, We are discribing the first report of subcutaneous phaeohyphomycosis by Drechslera dematioidea in a 9-year-old boy who presented a slow-growing 4x5.5cm erythematous plaque with somewhat verrucous and eczematous lesion on the dorsal aspect of his right foot after receiving a burn by boiling liquid at 2 years of age. Biopsy of the lesion revealed granulomatous inflammation, brownish spores in chain and planate-deviding sclerotic bodies in the epidermis and upper dermis. Findings by microscopic examination and consecutive cultures of scales and biopsy specimen were consistent with Drechslera dematioidea. The lesion was successfully treated with itraconazole.

We report a case of subcutaneous phaeohyphomycosis caused by Exophiala (E.) jeanselmei in a 75-year-old female, who showed subcutaneous abscesses on the both forearms for 8 months. Histopathologically, suppurative granulomatous inflammation and short hyphae & spores were observed. Fungal culture grew out the typical black-gray velvety colonies of E. jeanselmei after 3 weeks. The isolate grew well at 25degrees C, but very poorly at 37degrees C. No growth could be observed at 40degrees C. We confirmed E. jeanselmei by colony & microscopic morphology and temperature tolerance test. The patient had been treated with fluconazole for 3 months.

The dematiaceous fungi, characterized by having melanin in their cell walls, have become significant due to an increasing cause of human skin disease in Korea. The disease caused by dematiaceous fungi contain pityriasis (tinea) nigra, onychomycosis (in part), black piedra, keratomycosis (in part), chromoblastomycosis, phaeohyphomycosis, and eumycotic mycetoma (in part). Chromoblastomycosis is subcutaneous mycotic disease that contain sclerotic cells and histologically show pseudoepitheliomatous hyperplasia with microabscess, and phaeohyphomycosis is a group of mycotic infections that contain dematiaceous yeast-like cells, pseudohypae-like elements, hyphae or combination of these form in tissue.
