    Area of Science:

    • Oncology
    • Pathology
    • Endocrinology

    Background:

    • Primary solid carcinoid of the testis is an exceptionally rare tumor.
    • Carcinoid tumors typically arise from neuroendocrine cells, most commonly in the gastrointestinal tract.

    Observation:

    • A case of primary solid testicular carcinoid was studied ultrastructurally.
    • The tumor exhibited pleomorphic granules, characteristic of intestinal carcinoid tumors of midgut origin.

    Findings:

    • Primary solid testicular carcinoid tumors appear to exhibit benign behavior.
    • Review of 9 cases (including the current one) showed no evidence of metastases.
    • No patients presented with the carcinoid syndrome, with follow-up ranging from 20 months to 25 years.

    Implications:

    • Testicular carcinoid tumors are likely indolent neoplasms.
    • Further research into the specific characteristics and behavior of testicular carcinoids is warranted.
    • This finding aids in the differential diagnosis and management of testicular tumors.
