Sertoli cell nodule, abbreviated SCN, is a benign lesion of the testis that is usually incidental.
It is also known as Pick's adenoma, testicular tubular adenoma and tubular adenoma of the testis.
General
- Benign proliferation of Sertoli cells - associated with cryptorchidism (undescended testis).
- Not composed of a clonal cell population, i.e. not neoplastic; thus, technically, should not be called an adenoma.[1]
Gross
- Usually an incidental finding, rarely presents as a testicular mass.[2]
Microscopic
- Unencapsulated nodules composed of well-formed tubules.
- May contain eosinophilic (hyaline) blob in lumen (centre).
- Cells - vaguely resemble immature Sertoli cells:
- Bland hyperchromatic oval/round nuclei that are stratified - somewhat like a tubular adenoma of the gastrointestinal tract - key feature.

- OCT3/4 -ve (5/5 cases).
Other:
- PLAP -ve.

TESTICLE, LEFT, ORCHIECTOMY: - ATROPHIC TESTICLE WITH SERTOLI CELL NODULES. - NEGATIVE FOR GERM CELL NEOPLASIA IN SITU (INTRATUBULAR GERM CELL NEOPLASIA). - NEGATIVE FOR MALIGNANCY. COMMENT: The above findings are supported by immunostains. The tubules stain with alpha-inhibin and are negative for PLAP.
