Enterovesical fistula due to non-Hodgkin lymphoma in AIDS.

Enterovesical fistula associated with lymphoma is exceedingly rare. We report three patients with the acquired immunodeficiency syndrome who presented with fecaluria and pneumaturia. Non-Hodgkin lymphomas involving the intestine and the urinary bladder creating an enterovesical fistula were found at surgery in two patients and at autopsy in the third.
