Abstract
AbstractSkin metastasis of ovarian cancer is extremely rare. We report an unusual case of ovarian carcinosarcoma with cutaneous metastasis of carcinomatous component that displayed distinct clinical manifestation. A 48-year-old woman presented to the dermatologist complaining of a new onset of erythematous, plaque-like skin rash with multiple small nodules on the left inner thigh, the area measuring 8 × 5cm. While the patient had no history of dermatologic conditions, she underwent a total hysterectomy and bilateral salpingo-oophorectomy, omentectomy, and lymph node dissection 16 months ago with a pathology confirmed stage IIIC ovarian carcinosarcoma. Of note, the carcinomatous component, mainly adenocarcinoma with hybrid features of seromucinous, endometrioid and minor high-grade serous carcinoma, involved bilateral fallopian tubes, omentum, and parametrium with extensive lymph node metastases. A skin biopsy specimen revealed an adenocarcinoma involving epidermis, dermis, and subcutaneous tissue with nodular contours, consistent with metastatic carcinomatous component of carcinosarcoma. Both carcinomatous component of primary ovarian carcinosarcoma and metastatic adenocarcinoma in the skin demonstrated Pax8, WT-1, and ER positivity and a mutation pattern of p53. The patient passed away 15 months after identification of skin metastasis. This case represents a unique example of cutaneous metastasis of ovarian carcinosarcoma with distinct clinical manifestation and detailed histopathological description. Alertness to the possibility of cutaneous metastasis, in combination with clinical history, morphological and immunohistochemical findings, is critical for a definitive classification.
