Marked clinical improvement in a cat with a refractory non‐surgical case of dermatophytic pseudomycetoma responding to combination antifungal therapy

Feline dermatophytosis is a common dermatological manifestation that carries a good prognosis once a proper diagnosis has been achieved. In rare cases, dermatophytosis can manifest as a nodular dermatosis. This condition, known as dermatophytic pseudomycetoma, can be challenging to diagnose and treat. Surgical excision and systemic antifungal therapy are the standard treatments, which generally will carry a good prognosis for the patient. This case report describes a non‐surgical dermatophytic pseudomycetoma, which failed treatment with a singular antifungal agent, but improved when multiple antifungal medications were combined. This case highlights challenges associated with treating a cat with severe dermatophytic pseudomycetoma and concurrent feline leukaemia virus.
