Endometrial carcinoma with tibial bone metastasis: a case report and literature review

Metastatic Endometrioid Carcinoma Mimicking a Subungual Melanoma

CASE

We report a case of a 76-year-old female with a stage IB, grade I endometrioid endometrial carcinoma who presented with right-hip pain and an enlarging black, exophytic, subungual lesion on her right-small-finger distal phalanx. Clinically, the distal phalanx lesion was suspicious for a subungual melanoma; however, advanced imaging suggested metastatic disease, with lesions in the acetabulum, lungs, brain, vulva, and vagina.

CONCLUSION

Partial amputation of the right, small finger and vulvar biopsies confirmed an endometrial carcinoma. To our knowledge, this is the first described case of endometrial adenocarcinoma metastasis to the phalanx of an upper extremity, mimicking a subungual melanoma.

Bone Metastases of Endometrial Carcinoma Treated by Surgery: A Report on 13 Patients and a Review of the Medical Literature

BACKGROUND

The aim of this study was to describe the clinicopathological features of endometrial cancer (EC) patients with bone metastases treated with surgery and to systematically review the literature.

METHODS

We performed a retrospective study to include patients with bone metastases of EC at Peking University People's Hospital from 2000 to 2019. Clinicopathological features and survival outcomes were collected.

RESULTS

Among the 1662 patients with EC, 14 (0.84%) were identified with bone metastases, and all were treated surgically. Thirteen cases were analyzed. Four had bone metastases when diagnosed, and the remaining nine cases had bone metastases when first relapsed, with a median time to recurrence of 13 months (range, 5-144). The median age of the 13 patients was 58 years old (range, 45-76). Twelve were endometrioid carcinoma. The majority of sites of bone metastases were the pelvis, followed by the spine. The median overall survival (OS) was 57 months. We further combined the 13 patients with another 24 cases identified from literature research. There was no significant difference in clinicopathological characteristics between the patients with bone metastases when diagnosed and when they first relapsed. The median OS was numerically longer for patients with bone metastases when diagnosed than when they first relapsed (57 vs. 36 months, p = 0.084).

CONCLUSIONS

Patients with bone metastases of EC might benefit from comprehensive treatment based on surgery, as symptoms can be palliated and survival can probably be extended.

Endometrial adenocarcinoma with bone metastasis: A case report

We reported a female with endometrial adenocarcinoma who was evaluated with whole-body bone scan for new-onset bone pains 6 months after completion of treatment.
