[Rupture of the rotator cuff and skeletal muscle metastasis of primary lung carcinoma. A rare disease picture in differential diagnosis of shoulder pain]

Abstract

Skeletal muscles is an uncommon site for metastatic spreading of malignancies such as carcinoma of the lung. Thus, to date, there have been only a small number of reports of carcinoma of the lung spreading to the skeletal muscles. This case study reports the rare combination of a rotator cuff lesion of the shoulder with the late occurrence of the metastasis of a squamous cell carcinoma of the lung in the ipsilateral deltoid muscle. The problems that result from this combination concerning diagnosis and therapy are discussed.
