title: Ganglioneuroblastoma presenting as myasthenia gravis.
abstract: Neuroblastoma is one of the most common malignant neoplasms in infants and children under 5 years of age. The commonest manifestations are abdominal masses or metastases. The case reported showed unusual manifestations as the presenting features simulated myasthenia gravis in all aspects. He was a child, aged 3 years, who was admitted because of generalized weakness, inability to open his eyes and lethargy. Radiography showed an oval opacity at the right upper zone of the chest. A thorocotomy was performed and a tumour was removed from the posterior mediastinum. Histopathology confirmed diagnosis of ganglioneuroblastoma. There is only one similar report in the medical literature.
