Cutaneous malignant melanoma metastatic to a uterine leiomyoma: a case report.

BACKGROUND

Malignant melanoma is the sixth-most-common cancer in the United States and can spread throughout the body. This report represents the second case of a cutaneous melanoma involving a uterine leiomyoma.

CASE: A 49-year-old woman presented with an inguinal mass; biopsy revealed an undifferentiated neoplasm. Further examination and computed tomography revealed an enlarged, fibroid uterus. The patient underwent a total abdominal hysterectomy, bilateral salpingo-oophorectomy and right inguinal lymphadenectomy. Histologic examination of the inguinal lymph node and the leiomyoma revealed metastatic melanoma.

CONCLUSION

As the incidence of melanoma increases, metastasis to unusual locations, such as uterine fibroids, probably will be encountered more frequently.
