“…Thymic carcinoma is rare with an incidence of 0.15 cases per 100,000 [ 1 ]. There are 3 ways thymic carcinomas can metastasize: hematogenous, or lymphatic routes, and direct invasion of adjacent organs [ 5 ]. Thymic carcinoma often metastasizes to the regional lymph nodes and variable extra-thoracic organs, particularly bone, lung, and liver [ 6 ]; 80% of cases have local invasion of contiguous mediastinal structures, and 40% of cases present with metastatic spread to bones, lung, pleura, liver, or lymph node [ 7 ].…”

Metastatic lesions to the breast from extramammary malignant neoplasms are rare and reported account for 0.5–6.6% of all breast malignancies. Distant metastasis of thymoma is even rarer, especially to extrathoracic regions. We reported a woman with invasive malignant thymoma postneoadjuvant and resection of the thymoma, who developed breast metastasis 7 years later. Breast imaging showed high-density lesion with no intralesional microcalcifications and no significant axillary lymphadenopathy. Core biopsy and histopathology proved the lesion to be metastatic thymic carcinoma. Despite rarity, breast lumps with underlying extramammary malignancy should raise the suspicious of breast metastasis.

Background: Thymic carcinoma is prone to early metastasis and invasion, while its metastasis to the breast is particularly unique. Case Report: We describe a case of thymic epithelial tumor metastatic to the breast fulfilling clinical diagnostic criteria. A 47-year-old female patient diagnosed with stage IV thymic carcinoma and previously treated with chemoradiation was diagnosed with metastatic breast cancer during a periodic review. Color Doppler ultrasonography showed a low-echo real occupancy in the breast. Pathological examination of the breast mass confirmed the diagnosis of thymic carcinoma metastasis. Conclusion: Hematogenous metastasis of thymic carcinoma to the breast is rare but not exceptional, and long-term survival can be expected with appropriate treatment.

A 59-year-old woman was noted to have an anterior mediastinal mass on computed tomography at a regular follow-up 13 years after initial surgery for left breast cancer. Magnetic resonance imaging showed an anterior mediastinal mass. A total thymectomy with excision of surrounding lymphoid tissue was performed. Pathological examination of the resected tumor confirmed the diagnosis of thymic metastasis from breast cancer. The patient has been alive for 6 years after thymectomy. Metastases to the thymus are rare, but long-term survival can be expected with appropriate treatment.
