A woman in her 50s with relapsed refractory acute myeloid leukemia and a remote history of breast cancer was admitted for treatment of presumed fungal pneumonia based on new pulmonary nodules on imaging and elevated serum β-D-glucan levels. She subsequently developed multiple asymptomatic pink papules on the trunk and extremities. The patient was afebrile and was receiving broad-spectrum antibiotic, antifungal, and antiviral treatment for a prior episode of neutropenic fever. Clinical examination revealed scattered pink papules with a white firm center and dark brown core scattered throughout the chest, abdomen (Figure, A and B), back, groin, and upper and lower extremities. Laboratory workup was significant for leukopenia with neutropenia, anemia, and thrombocytopenia. Creatinine and transaminase levels were within normal limits. Blood cultures were negative. A punch biopsy from the left flank was obtained for hematoxylin-eosin staining, and a punch biopsy from the left leg was sent for tissue and fungal culture. Histopathological analysis was subsequently performed (Figure, C and D).

A. Disseminated candidiasis with transepidermal elimination
The analysis of the skin biopsy specimen revealed a large cluster of fungal organisms in the upper dermis extruding through a cuplike invagination of the epidermis into the stratum corneum (Figure, C and D). Periodic acid–Schiff (PAS) staining highlighted these fungal elements. Wound and fungal cultures subsequently grew Candida albicans. Histologic and laboratory findings supported a diagnosis of disseminated cutaneous candidiasis with transepidermal elimination, correlating clinically with the central core seen on examination. Ophthalmologic evaluation revealed chorioretinitis secondary to Candida infection, and otolaryngology assessment revealed thrush in the oropharynx. Blood cultures, however, remained negative. The patient’s antifungal regimen included amphotericin B and micafungin. The patient was transferred to the intensive care unit for septic shock 2 weeks after presentation and died shortly thereafter.
