Renal angiomyolipoma associated with neurofibromatosis and primary carcinoid of mesentery.

A patient with von Recklinghausen's disease manifested by dermal neurofibromatosis and cafe-au-lait spots presented with complaints of malaise, weight loss, lower extremity weakness, and a palpable left lower abdominal quadrant mass. Evaluation revealed a lumbar neurofibroma, a localized primary carcinoid tumor of the mesentery, and a left renal angiomyolipoma. Although an association between neurofibromatosis and carcinoid has been previously reported, we believe this is the first report documenting the association of all three entities.
