A woman presented with purulent infiltrating plaques on her hands and arms after a 7-year history of nephrotic syndrome. She was ultimately diagnosed with subcutaneous phaeohyphomycosis, which is caused by Alternaria section Alternaria. The lesions completely resolved after 2 months of antifungal treatment. Interestingly, spores (round-shaped cells) and hyphae were observed in the biopsy and pus specimens, respectively. This case report highlights that distinguishing subcutaneous phaeohyphomycosis from chromoblastomycosis may be difficult if the diagnosis is solely based on pathological findings. It also emphasizes that the parasitic forms of the dematiaceous fungi in immunosuppressed hosts may vary with the site and environment.

Few studies have focused on the infectious complications in kidney transplant recipients in tropical regions, particularly in the Caribbean. The primary objective of this study was to determine the incidence of bacterial, fungal, and parasitic infections in kidney transplant recipients in the French Caribbean and French Guiana. We included all patients who received a kidney transplant at the University Hospital of Guadeloupe between January 2014 and October 2016, with post-transplant follow-up in the French Caribbean.

Article Synopsis
- Phaeohyphomycotic cysts are subcutaneous infections commonly found in immunocompromised patients, presenting as plaques or nodules.
- Diagnosis involves histopathological and mycological tests to identify the organism.
- Treatment typically includes surgical excision and systemic antifungal medication, with this report highlighting a rare case in an immunocompetent person.

Phaeohyphomycosis is a fungal infection caused by dematiaceous fungi that presents as a superficial, cutaneous, subcutaneous, or systemic infection. Subcutaneous phaeohyphomycosis is the most common manifestation and presents as a subcutaneous nodule or cystic lesions and abscesses. It usually results from traumatic implantation of the saprophytic fungus from soil and vegetative matter; therefore, the commonest sites of infection are the extremities.

Article Synopsis
- Dematiaceous molds are dark environmental molds found worldwide, particularly in tropical and subtropical areas, with common types including Bipolaris, Cladophialophora, Exophiala, and Alternaria.
- These molds can cause a variety of diseases in both healthy and immunocompromised individuals, leading to issues like skin infections, allergic reactions, pneumonia, and sometimes serious systemic infections.
- Treatment generally involves antifungal medications such as itraconazole, voriconazole, or posaconazole, combined with measures to address the source of infection and reduce immune suppression, while efforts are underway to enhance diagnostic methods and treatment options due to high mortality rates associated with severe cases.
