Tamoxifen and giant endometrial polyp

Area of Science:

• Gynecology
• Oncology
• Pathology

Background:

• Tamoxifen is a common adjuvant therapy for breast cancer.
• Endometrial polyps are growths within the uterus.
• Giant endometrial polyps are rare and can present diagnostic challenges.

Observation:

• A patient on adjuvant tamoxifen for breast cancer developed a giant endometrial polyp.
• The polyp measured 10 x 6 x 3 cm and protruded from the cervical os.
• The mass was surgically removed and found to be benign on microscopic examination.

Findings:

• Tamoxifen use is associated with an increased risk of endometrial polyps.
• The size and presentation of this polyp were uncommon.
• Histological and ultrasonographic findings may be confounded by tamoxifen therapy.

Implications:

• Clinicians must be aware of tamoxifen's potential effects on the endometrium.
• Regular gynecological monitoring is crucial for patients on tamoxifen.
• This case highlights the importance of considering medication side effects in differential diagnoses.
