diffuse cutaneous leishmaniasis

dif·fuse cu·ta·ne·ous leish·man·i·a·sis

leishmaniasis caused by several New and Old World species and strains of Leishmania (L. mexicana amazonensis, L. m. pifanoi, possibly L. m. garnhami and L. m. venezuelensis; in Ethiopia, L. aethiopica, and unidentified leishmanial agents in Namibia and Tanzania). The condition is associated with a suppressed cell-mediated immune response, so that the nonulcerating, nonnecrotizing cutaneous lesions can spread widely over the body; great numbers of parasite-filled macrophages are found in the dermal lesions. Healing does not seem to occur unless an acquired cellular hypersensitivity can develop.
