[Muscular metastasis, first symptom of bronchial carcinoma (author's transl)].
One case of bronchial carcinoma in which a muscular metastasis was the presenting symptom is reported. Clinical features included pain and gradual swelling of left musculus supra-spinatus. Surgical biopsy showed intra-muscular metastasis of bronchial origin. Radiotherapy provided transient pain relief, but the patient died 15 months after the first symptoms. Metastatic tumors of skeletal muscles are found in some cases, when carefully searched for in routine autopsy surveys. Most of these tumors remain asymptomatic; in other cases clinical picture includes pain, swelling and diffuse or nodular induration of the involved muscles. Biopsy shows metastatic tumor in these muscles, which generally retains the same growth pattern as seen in the primary tumor.
