Invasive mycotic infection presenting as "foot lump" in an immunocompetent patient is extremely rare. The case highlights the difficulty in diagnosis of fungal infections of foot including attempts to isolate the fungus and non-response to anti-fungal agents. A 64-year-old lady with T2DM for four years presented with painless, gradually progressive swelling over plantar aspect of left mid-foot for six months. Foot examination revealed soft-to-firm lump over the plantar aspect of left mid-foot obscuring the lateral longitudinal arch...

We report a rare case of phaehyphomycosis in a 71-year-old heart transplant recipient Togo native patient. Four months after the transplant, he presented painless nodules on the right heel with superficial ulceration. The polyphasic identification uncovered a rare cause of phaehyphomycose: V. botryosa. The treatment combined surgical excision of the lesions and anti-fungal therapy with posaconazole. We discussed eleven reported cases in literature since 1990.

Scytalidium dimidiatum is a fungus found mainly in tropical and subtropical zones. Infection can cause a benign disease closely resembling dermatophytosis. In immunocompromised hosts, Scytalidium dimidiatum can also lead to phaehyphomycosis. Although awareness of these hyphae remains limited in developed countries, their incidence is growing due to increasing immigration and tourism. The rising incidence is well illustrated by three patients who presented onyxis and squamous-like manifestations on the arch of the foot upon returning from trips overseas and in whom various treatments were unsuccessful...
