Hypertrophic osteoarthropathy is characterized by clubbing and periosteal new bone formation along the shaft of the long bones of the extremities. Although various intrathoracic malignancies have been associated with the development of HOA, it has been extremely rare for HOA to occur in a patient with a thymic carcinoma. Recently, we experienced a 63-year-old woman diagnosed as a thymic carcinoma with hypertrophic osteoarthropathy. She had both digital clubbing and cortical thickening in her lower extremities identified radiologically. We herein describe this case with a review of the literature.

Breast metastasis from nonmammary malignant neoplasms is uncommon, and it accounts for approximately 2% of all breast tumors. Distant metastasis of thymoma is very rare, and especially to extrathorcic areas. We report a female who had a metastatic thymoma in her breast 20 years after undergoing resection for a non-invasive thymoma. She presented with a palpable mass in her left breast. Mammography and ultrasonogram showed a lobular mass at the anterior glandular portion. Histological examination after surgical excision revealed a metastatic thymoma.

A malignant tumor is generally believed to be very unlikely to metastasize to the thymus. Only three cases of thymic metastases have been reported so far in the medical literature. We report here a rare case of metastatic breast cancer to the thymus, which was detected by CT and PET scanning, and the metastasis was also confirmed by video-assisted thoracic surgery biopsy. Recognition of an unusual breast cancer metastasis, such as to the thymus, as well as the usual patterns of breast cancer metastasis will facilitate an accurate, prompt diagnosis and its appropriate treatment.

OBJECTIVETo improve the understanding of thymic neuroendocrine carcinoma (TNC) by retrospective analysis of the clinical data of 21 cases.

METHODSThe clinical data of 21 patients with TNC treated in the Peking Union Medical College Hospital from 1998 to 2010 were retrospectively analyzed.

RESULTSThere were 12 males and 9 females, with onset age ranging from 13 to 67 years and the mean age of 43 years. The clinical manifestation was diverse, in which the malaise of chest and back accounted for 57.1% (12/21), Cushing's syndrome 33.3% (7/21), multiple endocrine neoplasia type 1 accounted for 4.8% (1/21), pharyngeal malaise 4.8%, superior vena cava syndrome 4.8% (1/21) and asymptomatic patients accounted for 4.8% (1/21). Eighteen of them demonstrated metastasis, in which 13 had metastasis to lymph nodes and local vascular invasion, 9 to lung or pleura, 5 to bone, 1 to liver and 1 was recurred in situ. Twenty of them were treated by surgical resection. Eleven of them received radiotherapy and 9 chemotherapy after surgery. One patient was too severe to endure surgery, and was a treated by chemotherapy only.

CONCLUSIONTNC is rare, and its clinical features are complex, with a high level of malignancy. The first choice of treatment is resection. Adjuvant radiotherapy and/or chemotherapy may be applied in patients with metastasis.
