Peripheral T-cell lymphoma in HIV-positive patients.

Two cases of peripheral T-cell lymphomas in HIV-positive patients are reported: one case of T-pleomorphic small cell non-Hodgkin lymphoma in a 27 year-old bisexual male, and one case of a T-pleomorphic medium and large cell non-Hodgkin lymphoma in a 27 year-old female, whose husband was drug addicted. Both cases were studied on a morphological and immunohistological basis.
