Subcutaneous entomophthoromycosis masquerading as soft tissue neoplasm in breastfeeding mother.

Subcutaneous entomophthoromycosis is an infection caused by saprophytic, ubiquitous and highly opportunistic fungal pathogens. Individuals with immune disorders are frequently susceptible to these infections. Entomophthoromycosis is a rare fungal infection that primarily affects children andmen, and is known to cause infection in healthy individuals. Diagnosis of the disease is by demonstration of fungal elements using special stains, and the disease responds well to oral antifungal agents. Long-term antifungal agents reduce the need for surgical intervention when the disease presents as a mass. We report a case of an immunocompetent nursing mother in her 20s who presented with a soft tissue mass in her right arm. It was diagnosed as subcutaneous entomophthoromycosis and treated with long-term fluconazole. The lesion showed a significant reduction in size following treatment for 2 months. Subcutaneous fungal infection presenting as a mass-forming lesion in extremities may mimic a neoplasm. Fungal infection should be ruled out in inflammatory cell-rich lesions seen on histopathological examination.
