This is a case report of subcutaneous mycosis presenting as a non-healing left calf ulcer in an immunocompromised patient. Traumatic inoculation of the causative agent is the most likely route of infection. The diagnosis requires a detailed history and high clinical suspicion, confirmed by histopathological examination. The management requires a multidisciplinary team approach involving surgeon, pathologist, physician sub-specialised in infectious disease, wound care nursing team as well as social support services. The literature review recommended that the treatment of choice for such infection is surgical debridement in addition to optimal antifungal therapy.
