Collision tumors are distinct and rare groups of neoplasms characterized by occurrence of two histologically different neoplasms at one site as a single lesion without significant tissue admixture. They are described in different parts of the body including adrenal glands. Collision tumors reported in relation to adrenal gland are mainly combinations of adenoma and metastasis. Here we present a case of incidentally detected adrenal collision tumor with adenoma and hemangioma as components which is a very rare and unique occurrence.
