Sertoli cell nodule
Sertoli cell nodule, abbreviated SCN, is a benign lesion of the testis that is usually incidental.

| Synonyms | Pick's adenoma, testicular tubular adenoma, tubular adenoma of the testis |
|

| LM | unencapsulated nodules composed of well-formed tubules, +/eosinophilic (hyaline) blob in lumen (centre), cells - vaguely resemble immature Sertoli cells (bland hyperchromatic oval/round nuclei) but are stratified (somewhat like a tubular adenoma of the gastrointestinal tract) |
| LM DDx | Sertoli cell tumour, sex cord tumour with annular tubules, gonadoblastoma |
| IHC | alpha-inhibin +ve, PLAP -ve |
| Site | testis |

| Clinical history | +/-undescended testis |
| Prevalence | uncommon in general |
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.

TESTICLE, LEFT, ORCHIECTOMY: - ATROPHIC TESTICLE WITH SERTOLI CELL NODULES. - NEGATIVE FOR 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.
