epidermoid carcinoma or adenocarcinoma. (2) Less common causes of superior sulcus tumors, such as other primary malignant neoplasias of the chest, metastatic malignant diseases and benign pathologies, have been described. (3)(4)(5)(6) However, Pancoast syndrome involving small cell lung carcinoma is rare. (1) Here, we present the case of a patient with Pancoast syndrome caused by small cell lung carcinoma.
Case reportWe report a case of a 74-year-old hypertensive white male, a painter, with peripheral vascular insufficiency of the lower limbs. The patient had been a smoker for 54 years (one pack of cigarettes per day). He presented with a two-month history of sharp, right-sided pleuritic pain, accompanied
IntroductionPancoast syndrome is defined as a set of signs and symptoms secondary to the neoplastic impairment of the brachial plexus, parietal pleura, first/second ribs (and adjacent vertebral bodies), first/second thoracic nerves, paravertebral sympathetic chain and stellate ganglion, due to a tumor in the superior sulcus, also known as a Pancoast tumor. Clinically, the symptoms are pain in the shoulder and dorsal face of the ipsilateral affected arm and hypesthesia of the elbow/forearm, evolving to weakness and muscle hypotrophy, including atrophy of the ring finger and little finger. Horner's syndrome, which involves stellate ganglion impairment, clinically manifesting as palpebral myosis/ptosis, enophthalmos and anhidrosis, can be included in the spectrum of Pancoast syndrome features.
AbstractPancoast syndrome consists of signs and symptoms resulting from a tumor affecting the pulmonary apex and adjacent structures. The process is typically caused by a neoplasm. The majority of cases of Pancoast syndrome are caused by bronchogenic carcinoma. The most commonly found histologic subtypes are adenocarcinoma and epidermoid carcinoma. There have been very few reports of small cell lung carcinoma in the genesis of Pancoast syndrome. We describe the case of a patient with Pancoast syndrome caused by small cell lung carcinoma and discuss the aspects related to the diagnosis and treatment.

ResumoA síndrome de Pancoast consiste de sinais e sintomas decorrentes do acometimento do ápice pulmonar e estruturas adjacentes por um tumor. Na maioria das vezes, o processo causal é uma neoplasia. O carcinoma broncogênico é a principal neoplasia causadora da síndrome. Os subtipos histológicos mais encontrados são o adenocarcinoma e o carcinoma epidermoide. A ocorrência de carcinoma de pequenas células de pulmão como gênese da síndrome de Pancoast é rara, com poucos relatos na literatura. Descrevemos o caso de um doente com síndrome de Pancoast causado por um carcinoma de pequenas células de pulmão, discutindo aspectos referentes ao diagnóstico e à terapêutica.Descritores: Síndrome de Pancoast; Carcinoma de pequenas células; Neoplasias pulmonares.
