A histopathological study of different clinical forms of cutaneous leishmaniasis

Biopsy specimens for histopathological study were taken from 15 parasitologically proven cases with different clinical forms of cutaneous leishmaniasis (CL) including two patients with disseminated CL in the form of subcutaneous nodules and satellite papules. The clinical picture of these patients was also reported. The study revealed that the histopathological manifestations were variable, ranging from a diffuse infiltrate in the acute stage to a tuberculoid architecture in the chronic stage. One patient had perineural inflammatory cell infiltrate consisting of lymphocytes, plasma cells and macrophages.
