Forearm Metastases as Unsuspected First Manifestations of Lung Adenocarcinoma

Özet

An 83-year-old male who was a former smoker had pain on the left forearm accompanied with progressive swallowing in the last four tofive months. Imaging studies revealed a cystic necrotic mass on the flexor digitorum superficialis muscle (biopsy: striated muscle tissueinfiltrated by an adenocarcinoma). A whole-body computerized tomography (CT) scan demonstrates the presence of two lung massesthat were suspicious of malignancy. Diagnosed as having stage IV lung adenocarcinoma (cT4NxM1b, IASLC TNM 8th), he received chemotherapy with a carboplatin/pemetrexed-based regimen and local palliative radiation for the control of arm pain.
