Neuroendocrine tumors most commonly occur in the gastrointestinal tract, lungs and pancreas. Primary testicular neuroendocrine tumors are rare, constituting 0.23% of all testicular tumors. A 35-year-old man presented to urology department with a painless left scrotal mass. He had no history of trauma. Scrotal Doppler ultrasonography revealed a 2×1.5 cm, well-circumscribed, solid lesion. Tumor marker levels were normal and staging computed tomography demonstrated no evidence of metastasis. The patient subsequently underwent left radical orchiectomy. The orchiectomy material, grossly showed a 1.4x1.2 cm, well-circumscribed, yellow, solid mass. On histopathologic examination, primary testicular carcinoid tumors cannot be distinguished from well-differentiated neuroendocrine carcinoma. The diagnosis of a primary testicular carcinoid tumor was made after ruling out an extratesticular neuroendocrine tumor using clinical and radiological data. This rare case is presented with clinical, morphological and immunohistochemical features.
