Osteolysis of the Carpus as a Presentation of Pancoast's Tumor

Abstract

Lung cancer is most often located in the right upper lobe and is called a Pancoast tumor. On many occasions, the Pancoast tumor begins with osteomyoarticular manifestations. A 72-year-old white male patient of peasant origin is presented who attends the Guard Corps because for a few weeks an increase in volume has been noted on the back of the right hand accompanied by pain in the absence of trauma. An X-ray of the hand was performed, observing osteolysis of the carpal bones, in the preoperative preparation a chest X-ray was performed where an image of condensation of the upper lobe of the right lung was observed. An excisional biopsy of the carpal lesion was performed, the result of which was metastasis of highly undifferentiated lung adenocarcinoma.
