Summary
A rare prostatic leiomyoma, a benign smooth muscle tumor, was incidentally found in a man. This tumor exhibited nuclear atypia, a feature usually seen in uterine leiomyomas.
Area of Science:
- Uropathology
- Surgical Pathology
- Oncology
Background:
- Prostatic leiomyomas are rare benign smooth muscle neoplasms.
- They are often asymptomatic and discovered incidentally.
- Nuclear atypia in leiomyomas can mimic malignancy, posing diagnostic challenges.
Observation:
- A 53-year-old male patient underwent prostatectomy for benign prostatic hyperplasia.
- An incidental prostatic leiomyoma with significant nuclear atypia was identified.
- The atypia resembled that occasionally observed in uterine leiomyomas.
Findings:
- The smooth muscle origin of the prostatic lesion was confirmed via electron microscopy.
- This represents the third reported case of prostatic leiomyoma with nuclear atypia.
- The histological features warrant careful evaluation to exclude malignancy.
Implications:
- This case highlights the importance of recognizing benign leiomyomas with atypia in the prostate.
- Accurate diagnosis is crucial to avoid misclassification as sarcoma.
- Further research may elucidate the behavior and potential significance of atypical prostatic leiomyomas.
