A case of small cell lung carcinoma presenting with Eaton-Lambert myasthenic syndrome and acanthosis nigricans

Abstract

Paraneoplastic manifestations can be the initial clue to the presence of an occult neoplasm. Here we report two unique paraneoplastic manifestations of acanthosis nigricans and Eaton-Lambert myasthenic syndrome occurring simultaneously in a patient with small cell lung cancer, months before the diagnosis of the primary tumor. Clinical importance of paraneoplastic syndromes for early diagnosis is emphasized.
