Skin metastases in ovarian carcinoma: a report of nine cases and a review of the literature

Objective. Cutaneous involvement is unusual at presentation and during the course of ovarian carcinoma. The aim of the present study was to determine the incidence, clinicopathologic characteristics and prognostic factors of skin metastases in ovarian cancer patients. Methods. A retrospective chart review was conducted on 220 patients with epithelial ovarian carcinoma treated at our unit between 1991 and 2001. Pertinent clinical information, pathologic data, treatment, and prognostic factors for survival following documentation of skin metastases were collected. Survival time was calculated from the time of diagnosis of ovarian cancer and from the time of diagnosis of the cutaneous metastasis. Results. FIGO stage at the time of ovarian cancer diagnosis was stage III = five patients (56%), and stage I and stage IV = two patients each (22%). Most patients had serous papillary cystoadenocarcinoma of the ovary (78%), and one each had endometrioid and mucinous carcinomas (12%). Seven patients (78%) had poorly differentiated tumors. Only one patient had a skin metastasis at the time of ovarian cancer diagnosis; in the remaining patients the average time of appearance of skin metastases after the diagnosis of ovarian cancer was 23.4 12 months (range 4 to 37). The diameter of the skin lesions ranged between 0.5 and 3 cm. Three patients had a single skin nodule, while six had multiple skin lesions. Eight patients (89%) have died of disease and median survival after diagnosis of the skin metastases was 4 months (range 2 to 65). One patient (Cases 1) is alive without tumor 4 months after diagnosis of the skin metastases. Overall survival after diagnosis of skin metastasis from ovarian cancer was 4 months (range 2 to 65). Conclusion. Skin involvement is a late complication that occurs rarely in ovarian cancer patients. Prognosis after skin metastases is poor and the most important prognostic factor associated with survival is the interval time between diagnosis of ovarian cancer and documentation of cutaneous involvement.
