Cutaneous Phaeohyphomycosis of the Right Hand Caused by Exophiala jeanselmei: A Case Report and Literature Review

Chemotherapy Extravasation Causing Soft-Tissue Necrosis Mimicking Infection: A Longitudinal Case Study

Extravasation injuries are uncommon, underreported, and often misdiagnosed in patients. The signs and symptoms of extravasation injuries vary from simple pain and tenderness to tissue necrosis and potentially fatal secondary infections. Extravasation may progress to more severe conditions such as necrotizing fasciitis (NF) or cellulitis, so special care is needed by physicians to identify and treat these injuries correctly. Here, we explore a case study on extravasation injuries mimicking NF leading to infectious complications and discuss the proper diagnosis and treatment of extravasation injuries as well as other NF-mimicking diseases. We present a case of a 44-year-old Hispanic male with a history of B-cell acute lymphoblastic leukemia who underwent inpatient chemotherapy treatment via a chest port.

Trauma-Induced Phaeohyphomycosis in an Immunocompetent Host on Dupilumab

Phaeohyphomycosis is a rare infection caused by dematiaceous fungi containing melanin in their cell wall. Patients are often immunocompromised, and cases seen in immunocompromised hosts have increased in recent years. Dupilumab, a monoclonal antibody against interleukin-4 (IL-4) and interleukin-13 (IL-13) used for the treatment of atopic dermatitis, has been linked to hypersensitivity reactions resulting in facial redness, and there is growing evidence that dupilumab may increase susceptibility to yeast infections as well. We present a case of trauma-induced cutaneous phaeohyphomycosis in an immunocompetent host on dupilumab. As dupilumab becomes more commonly encountered in practice, this case is meant to explore the potential relationship between dupilumab and predisposition to opportunistic fungal infections.
