Unusual sternal mass: Adenocarcinoma with unknown primary site

Abstract

We are reporting a case of sternal mass-histologically proven high-grade adenocarcinoma. Despite exhaustive investigations, no other primary site was detected. It was difficult to differentiate from metastasis or from primary skin adnexa, but whatever diagnosis is made, wide surgical excision with reconstruction is recommended for improvement of life quality.
