REGI BOSQUE, Meritxell  y  VILLAR BALBOA, Iván. Cervicobrachialgia: initial symptom of Pancoast syndrome. Rev Clin Med Fam [online]. 2013, vol.6, n.1, pp.51-53. ISSN 2386-8201.  https://dx.doi.org/10.4321/S1699-695X2013000100010.

Pancoast syndrome is caused by a tumour in the pulmonary apex, with local spreading to the lower brachial plexus, paravertebral sympathetic chain, vertebral bodies, and first, second and third ribs. Most Pancoast syndrome cases are caused by non-small cell bronchogenic carcinoma, mainly by squamous cell carcinoma, followed by adenocarcinoma and large cell carcinoma. Lesions in the superior pulmonary sulcus can give rise to shoulder and arm pain, Horner syndrome and muscle atrophy of the hand. Owing to the peripheral location of the tumour, symptoms such as coughing, hemoptysis and dyspnoea are uncommon until more advanced stages of the illness.

Palabras clave : Pancoast syndrome; Non-small-cell lung carcinoma; Shoulder pain.
