Primary cutaneous aspergillosis, mimicking malignancy, a rare presentation in an immunocompetent patient

Aspergillus species are ubiquitous opportunistic molds that cause both allergic and invasive syndromes. A 65-year-old female, farmer by occupation, presented with left upper limb and trunk swelling for one year, associated with pain, tightening of skin, and vesicles with watery discharge. Local examination showed a diffuse swelling extending from left arm to forearm and lateral chest wall associated with edema, induration, and raised temperature. The swelling was firm to hard with superficial skin ulcers and black eschar. Hematological investigations of the patient showed raised total WBC count and peripheral blood eosinophilia. Patient had no history suggesting immunosuppression. Clinico-radiological impression was left breast carcinoma with secondary skin involvement. fine-needle aspiration cytology (FNAC) from the swelling showed inflammatory cells, necrosis, epitheloid cell granulomas, and giant cells along with branching hyphae of variable thickness, confirmed on Gomori Methenamine Silver stain as fungal hyphae. Culture was advised which identified the species as Aspergillius fumigatus. Primary cutaneous infection by A. fumigatus in an immunocompetent patient is unheard of. FNAC has an important role in resolving diagnostic dilemma in primary cutaneous aspergillosis, which may mimic malignancy as in our case.
