Vet Pathol. 2013 Sep;50(5):749-52. doi: 10.1177/0300985813480192. Epub 2013 Mar 12.

Abstract

Concurrent leishmaniasis and neoplasia has been reported in dogs. This study describes the presence of the protozoa within the cytoplasm of neoplastic cells in 3 different types of tumors. Leishmania amastigotes were detected by light and transmission electron microscopy and immunohistochemistry in a fibrosarcoma, a T-cell lymphoma, and an adrenocortical adenoma.

Keywords: Leishmania; canine neoplasms; immunohistochemistry; ultrastructure.
