Abstract

Primary carcinoid tumor is rarely associated with mature teratoma in the testis. In the few cases reported, the primary carcinoid tumors in the testis were often microscopic in size. Although it has been generally accepted that carcinoids arising in teratomas have an indolent clinical course, some of these tumors have been reported to metastasize and cause death of the patient. Therefore, long term follow up may be warranted for patients having primary testicular carcinoid tumors irrespective of coexisting teratoma. We report a case of primary testicular carcinoid tumor of microscopic size incidentally found in mature cystic teratoma occurring in a 44 year-old male patient.
