Background:
The advent of antiretroviral therapy increased the life expectancy of human immunodeficiency virus (HIV)-positive patients and, consequently, the morbidity and mortality due to neoplasms. Plasmablastic lymphoma is one such neoplasm that generally presents with involvement of the oral cavity; cases of extra-oral involvement are rare.
Case Report:
We report a case of plasmablastic lymphoma in a 46-year-old woman for whom the initial clinical manifestation was a painless perineal tumor accompanied by fecal incontinence.
Conclusions:
The possibility of this neoplasm should be considered in patients with HIV/acquired immune deficiency syndrome (HIV/AIDS) because its early diagnosis is essential so that the start of the treatment is not delayed.
