ABSTRACT
Deep cutaneous mycoses (DCMs) and skin fungal infections can cause significant morbidity until diagnosed and treated. In immunocompromised people, Candida spp., Aspergillus spp., and Fusarium spp. fungi can cause these infections, but dermatophytes, especially Trichophyton rubrum and T. mentagrophytes, are the most common. Superficial erythematous lesions become firm subcutaneous nodules, ulcers, abscesses, or sinus tracts. In advanced cases, DCMs can cause osteomyelitis and bone loss. DCM included mycetoma, a chronic infectious disease of the skin, subcutaneous tissues, and bones. In some areas, it is endemic and can mimic cutaneous tuberculosis or cancerous lesions, making diagnosis difficult. Clinical presentation, radiological findings, and microbiological culture are used to diagnose with molecular methods helping in culture-negative cases. An immunocompetent farmer with a wrist lesion initially suspected as cutaneous squamous cell carcinoma was histologically diagnosed as eumycetoma, emphasizing the importance of considering deep mycoses in high-risk individuals and their heterogeneous clinical presentation.
