Dermatophytes, yeasts, and non-dermatophytic molds (NDMs) are the most common causal agents of foot mycoses. It is uncommon in women and children. Fusarium species are widely distributed and can be detected in several environmental sources such as soil, air, and plants. Some predisposition factors could be related with this disease including barefoot, wearing occlusive shoes, sweating of the feet. The most common cause of localized fusarium infection is trauma. A 11-year-old boy, complained of itching and red patches on right and left feet over the last year. Patient used to play barefoot, usually on the ground, in the fields and often played when it was raining. Patient also had a history of being stabbed by a twig. Patient used to wear socks for a long time at school. On physical examination at right and left plantar pedis regions showed multiple erythematous macules with firm margins,covered with thin scales on top, plaques with yellowish crusts on top, erosions,no pus and no pustules. Potassium hydroxide 20% examination revealed fungal hyphae, and white and cotton macroscopic fungi were found from fungal culture examination. Pink or violet center, and becoming bluish-brown are present sporoconidia. Microscopically, it showed sickle or canoe shaped thin-walled macroconidia with 3–4 septa, microconidia, chlamydospore. Showed concordance with the feature of spesies namely fusarium solani. Patients received itraconazole 100 mg twice a day for 1 month and cetirizine 10 mg once a day, clinical cure was noted and mycological cure was obtained after 1 month of treatment. Foot mycosis due to non-dermatophyte species, namely fusarium solani is a rare case. Clinical manifestation might mimick dermatophyte foot mycosis. A detail history and physical examination, supported by identification of etiology will lead to correct diagnosis and prompt treatment. Education of patient on how to prevent reccurency by avoiding predisposition factor of the disease is the most important point of care.References
