File:Leiomyoma.jpg
Smooth muscle tumor (in this case leiomyoma).

Gross processing

Gross examination

Examine and describe:[1]

  • Location
  • Number of tumors, if multiple
  • Size
  • Demarcation

Selection

In case of hysterectomy, submit pieces from all smooth muscle tumors >5 cm in diameter.[1]

Submit any macroscopically abnormal parts of the tumors (hemorrhagic, necrotic, brittle or softening areas, and areas with blurry delimitation).[1]

Microscopic examination

Distinguish leiomyoma (benign) from leiomyosarcoma (malignant).

Further information: Evaluation of tumors

Microscopic report

Example:

File:Histopathology of uterine leiomyoma.jpg
Smooth muscles in a whorled pattern. No atypia.
