Abstract:

Carcinoid tumor of the testis accounts for less than 1% of all testicular neoplasms and can be a primary pure carcinoid or it can be seen either as a mixed tumor with teratoma or as a metastasis of carcinoid tumor originating from another site. A 45 years old male patient complaining of an aching mass in left testis for one year applied to our outpatient clinic. An inguinal orchiectomy was performed after diagnosis of tumor was made. During pathologic examination, there was no teratomatous or any other germ cell tumour component and also no intratubular germ-cell neoplasia was detected within neighbouring testicular tissue. Immunohistochemically, the tumour was pancytokeratin (+), PLAP (-), NSE (+), chromogranin (+) and synaptophysin (+) with a Ki-67 proliferative index of 1-2 %.
