Atypical epidermal alterations in chronic Leishmania mexicana mexicana lesions fo C3H mice
C3H mice chronically infected with Leishmania m. mexicana, and in some groups treated with BCG or levamisole, presented atypical epidermal alterations, including pseudoepitheliomatous hyperplasia, hyperkeratosis and dysplasia. These alterations increased in frequency and intensity during the course of infection, but were not related to lesion size or tissue parasite load. Age matched normal, BCG and levamisole treated control mice, examined simultaneously, did not show epidermal modifications. In infected mice the dermis and hypodermis presented an inflammatory infiltrate of histiocytes, lymphocytes and plasma cells, accompanied at times by neutrophils and eosinophils, which did not vary with duration of infection.
