Summary
Backgrounds: Small cell carcinoma (SCC) is characterised by high metastatic potential and the possibility to metastasize to practically any tissue. Small cell carcinoma of the ovary (SCCO) has a very poor prognosis and patients usually die within one year of the initial diagnosis. Breast metastases from SCCO are extremely rare. Case: We present a 67‑year- old female patient with SCCO who initially presented with bone and bilateral breast metastases. Considering the clinical presentation, the patient’s age, the absence of hypercalcemia and histological characteristics, a diagnosis of pulmonary type SCCO was made. There was no tumour present in the lungs at the time of the initial diagnosis and thus we ruled out pulmonary SCC. Results: Initially, the patient was treated with radiotherapy of the bone lesion and systemic chemotherapy (etoposide with carboplatin) with the result of partial remission. Then, radical abdominal surgery was performed. Six months later she was diagnosed with progressive disease in the bone, soft tissue including the breast as well as new lesions in the right kidney, pelvis and lungs. She was treated with 2nd line chemotherapy (topotecan with cisplatin) with the result of progressive disease. Because of mediastinal lymphadenopathy, which was causing tracheobronchial compression, radiotherapy was administered with a good palliative outcome. Nine months later, multiple brain metastases were diagnosed and she was treated with whole brain radiotherapy. Shortly after brain irradiation, her status deteriorated rapidly and she died two years after her initial SCCO diagnosis. Conclusion: Extrapulmonary small cell carcinoma is a clinicopathological entity distinct from pulmonary small cell carcinoma. It is very rare and therefore there is very little information available regarding treatment of this disease. In contrast to experience in the treatment of pulmonary small cell cancers, prolonged survival is not common.
