37. Leiomyoma of uterus
Organ: Uterus
Description:
We can see a well-circumscribed, encapsulated tumor with an expansile border. The uterine cavity has been compressed. A nodule is seen inside the tumor.
Diagnosis: Leiomyoma of the uterus
Risk factors:
- Bad diet
- Genetics
Theory:
A leiomyoma is a benign tumor of smooth muscle. It often occurs in myometrium. The malignant version of this tumor would be a leiomyosarcoma.
The morphology of this tumor is similar to any other benign tumor.
The compressed uterine cavity causes characteristic symptoms, like:
- Dysmenorrhea
- Infertility
- Menorrhagia
The nodule can be either bleeding, hyaline, fibrosis or necrosis due to the tumor. (It’s definitely not clonal evolution or expansion.)
