RESUMEN
BACKGROUND: Dematiaceous, or dark-pigmented, fungi are known to cause infections such as phaeohyphomycosis, chromoblastomycosis, and mycetoma. These fungi are becoming increasingly important opportunistic pathogens in solid organ transplant recipients (SOTR). We present a retrospective chart review of 27 SOTR who developed phaeohyphomycosis infections post transplant from 1988 to 2009. METHODS: Cases were reviewed for fungal species isolated, date and source of culture, immunosuppressive and fungal therapy used, and outcome. The majority of isolates obtained were from the skin and soft tissue, with 3 pulmonary and brain abscesses. RESULTS: The time from transplantation to onset of infection ranged from 2 months to 11 years. The species isolated were Exophiala (11), Ochroconis (3), Alternaria (2), Phoma (2), Wangiella (1), Cladosporium (1), Aureobasidium (1), Chaetomium (1), Coniothyrium (1), and non-sporulating fungi (2). An additional 4 patients had infections confirmed by pathology, but no cultures were done. Most of the affected skin lesions were surgically debrided and treated with itraconazole; 2 patients were treated with voriconazole and 2 with amphotericin D. Death from fungal disease occurred only in patients with pulmonary and brain abscesses. CONCLUSIONS: As the number of SOTR increases, so does the incidence of fungal infections in that population. Surgery, along with antifungal therapy and a reduction in immunosuppression, are the cornerstones of treatment.

Suicidal ingestions of fireworks containing yellow phosphorus occur often during holidays. A case is reported of a 17 year old woman who intentionally ingested an estimated amount of 5.5 mg of yellow phosphorus, presenting with upper abdominal pain as the only complaint, a physical examination was normal. Blood tests showed a considerable decrease in the granulocyte count; the bone marrow biopsy revealed a decreased cellular mass with degenerative changes. Spontaneous remission was observed during the next 48 hours, with no further complaints.
