The role of surgical interventions in stage IVb thymic carcinoma, as classified by the TNM and Masaoka-Koga staging systems, remains controversial; although some patients present with resectable disease, others do not. We report a case with supraclavicular metastasis and sternal invasion.

The first case involved a 63-year-old woman with a sternal mass, near the right breast, initially suspected to be a sebaceous cyst.
