Breast involvement in visceral leishmaniasis.

Visceral leishmaniasis usually involves the bone marrow, lymph nodes, liver and spleen. Involvement of the eye or respiratory or gastrointestinal systems is very rare and usually occurs in immunodepressed patients. Only one case of breast involvement by protozoa has been reported in the literature. We report a case of a visceral leishmaniasis with a solid breast mass caused by leishmania and diagnosed by sonography-guided core biopsy.
