Summary
This case report details an unusual endometrioma in an 83-year-old male, potentially linked to long-term treatment for prostate cancer. The study reviews male endometriosis origins, noting prostatic utricle remnants.
Area of Science:
- Urology
- Pathology
- Reproductive Medicine
Background:
- Endometriosis is typically observed in females, characterized by the presence of endometrial tissue outside the uterus.
- The development of endometriosis in males is rare and its etiology remains debated, with theories involving Mullerian remnants.
Observation:
- An 83-year-old male developed an endometrioma of the lower abdominal wall after approximately 10 years of treatment for presumed prostate carcinoma.
- Chromosomal evaluation confirmed a normal male phenotype, and no embryonic remnants were identified.
- Histopathology revealed adenocarcinoma, distinct from the initial presumed diagnosis.
Findings:
- The patient's abdominal wall mass resolved, but low-grade prostate adenocarcinoma persisted.
- The prostatic utricle, a remnant of the embryonic uterus, is considered a likely origin for male endometriosis.
- The patient died from cardiovascular disease, not prostate cancer.
Implications:
- This case highlights the rare occurrence of endometriosis in males and its potential association with hormonal therapies or prostatic anomalies.
- Further research into the origins and management of male endometriosis is warranted.
- Understanding the embryological development of the urogenital system is crucial for explaining such rare conditions.
