Metastases are synonymous of
malignant neoplasm in advanced stage and so associated with a poor prognosis.
As the first manifestation of cancer disease, the muscle metastasis is very
rare. The definitive diagnosis of its presence is made based on histology. The
authors presented the case of a patient with a lung adenocarcinoma, being with
first manifestation of it, a muscle metastasis only about a month later there
were clinical manifestations with imaging appearance that led to the diagnosis
of a primary neoplasm. The rare manifestation of the disease motivated the
study and surveillance of the patient and lead to the diagnosis.
