[Sweet's syndrome and motor neuron disease associated with esophageal carcinoma]

The paraneoplastic syndromes are an a group of clinical manifestations of uncommon frequency that they are associated with tumors and they often are precursors of these. The Sweet's syndrome is a dermatosis characterized by fever, erythematous plaques and infiltrate consisting of mature neutrophils. It occurs occasionally in association with hematologic malignancies and is very rare with solid tumors. The isolated motor neuron disease is rare like paraneoplastic syndrome. We report the case of a patient with epidermoid carcinoma of esophagus that it was diagnosed after beginning clinically with two paraneoplastic syndromes: Sweet's syndrome and motor neuron disease.
