| Popis: | Phaeoacremonium parasiticum was identified as the causative agent of a phaeomycotic cyst seen just below the right knee of a 59-year-old healthy woman. She had no history of trauma. Direct KOH examination of the pus aspirated from the subcutaneous nodule revealed abundant mycelia, which were not too deeply brown in color. The nodule was surgically excised, and there was no recurrence during a half year of observation. Tissue section of the excised material revealed rather a large cavity extending from the cutis to the subcutis. The cavity had a thick wall composed of granulomatous tissues. Mycelial and yeast-like fungal elements were seen within the cavity and the granulomatous tissues. A dematiaceous fungus was cultured from both pus and the excised material. The isolates were characterized by a dark green to black colony, unbranched or infrequently branched, brownish conidiophores bearing an aculeate monophialide with a narrow funnel-shaped collarette, and slimy, hyaline, one-celled, ellipsoid to allantoid conidia. |
