title: Late cutaneous metastases in C3H SCID mice infected with Leishmania amazonensis.
abstract: The biological behavior of Leishmania amazonensis in the mammalian host is highly variable, resulting in local to diffuse cutaneous lesions that sometimes metastasize. Inflammation and, more specifically, CD4+ T cells have been shown to enhance metastases in mice infected with L. amazonensis, suggesting that the process may be lymphocyte mediated. However, we document, in this study, the development of multiple cutaneous metastases in C3H SCID mice infected with L. amazonensis. This shows that functional T and B cells are not required for metastases to occur.
