Mikael Häggström [note 1]
On this resource, the following formatting is used for comprehensiveness:
- Minimal depth
- (Moderate depth)
- Weigh the specimen.
- The size of the testis in 3 dimensions
- The spermatic cord length and diameter
- Ink the tunica vaginalis.
- Cut through tunica vaginalis with scissors
- Bisect the testis in the plane of the epididymis.
- If any tumor:
- Photograph the cut surface.
- Measure the size of the tumor in 3 dimensions
- Describe the gross appearance.
- Measure the distance of the tumor from the tunica vaginalis
- Note tumor extension: up to, into, or through the tunica albuginea or vaginalis.
- Measure the distance of the tumor from the epididymis and spermatic cord, and note any epididymal and spermatic cord involvement.
- Describe the remaining testicular parenchyma.
- If the specimen is large, serially section perpendicular to the long axis.
Generally including the following:
- The proximal spermatic cord margin en face[note 2].
- For any tumor:
- At least 1 section per cm of tumor, including the closest penetration of tunica albuginea/vaginalis and epididymis.
- Grossly different areas of tumor to determine which components are present (in case of potential mixed germ cell tumor).
- Additional sections of the spermatic cord
- Normal (uninvolved) testis.
- Any found lymph nodes
In case of orchiectomy for undescended testis, submit the entire testicular parenchyma to evaluate for GCNIS (germ cell neoplasia in situ).
Look mainly for:

- ((Optionally, disorders of spermatogenesis.))
Example in a normal case:
|Right testicle and spermatic cord, radical orchiectomy:|
Benign testis(, negative for malignancy).
