Abstract

Neuroendocrine carcinoma (NEC) can rarely be associated with Merkel cell dysplasia.  The clinical presentation is usually nonspecific and mild. Paraneoplastic MG is a rare autoimmune phenomenon related to esophageal NEC. We report a case of esophagus tumor having uncommon histology - (NEC) small cell type having Merkel cell dysplasia in the overlying epithelium, presenting as paraneoplastic Myasthenia gravis (MG). Neuro-muscular symptoms may be caused by paraneoplastic syndrome with underlying malignancy. The treatment options are different for esophagus squamous cell carcinoma and adenocarcinoma.

Keywords: Esophagus, Endoscopic ultrasound, Myasthenia crises, Merkel cell dysplasia, Neuroendocrine carcinoma.
