Skin biopsy distinguishes cutaneous leishmaniasis from lobomycosis in Colombian soldiers

Lobomycosis (AKA lacaziosis) is an implantation mycosis endemic to the Amazon basin, caused by Lacazia loboi. Nodular keloid lesions grow slowly and can cause disfigurement. Biopsy of lesions shows many thick-walled yeast cells forming chains, which may co-occur with other infections (e.g. leprosy, leishmaniasis) or squamous cell carcinoma.
