Abstrakt: Background: Curvularia is a filamentous dematiaceous fungus increasingly recognized as a pathogen in immunocompromised patients. The most common clinical entities associated with this fungus are allergic sinusitis, cutaneous infection and keratitis. In this article, a report on the first clinical case of Curvularia pallescens cutaneous infection in Spain and its treatment is described.
Case Report: A 68 year-old man with a history of lung transplantation presented to Dermatology Unit due to a skin lesion in the knee that had been evolving for 6 months. A skin biopsy was performed for its study. In the histopathological study, an intense and non-specific inflammatory reaction in the dermis was observed, and with Grocott stain and periodic acid Schiff abundant septate hyphae and spores were found in the dermis. The culture of the sample revealed a filamentous fungus whose microscopic examination allowed to identify the genus as Curvularia. Using MALDI-TOF mass spectrometry and molecular identification, the fungus was finally identified as Curvularia pallescens. The patient underwent surgical resection of the lesion and was treated with posaconazole, evolving favorably.
Conclusions: The species of Curvularia should be considered causal agents of fungal skin infections in immunosuppressed patients. This clinical case, which showed good clinical response after surgical resection and treatment with posaconazole, is the first described in Spain due to this species.
