title: Esophageal carcinoma with pseudohyperparathyroidism and hypercorticism.
abstract: An unusual case of bihormonal activity by squamous cell carcinoma of the esophagus is presented. It is a rare presentation of esophagus carcinoma because of the following reasons: 1. Synthesis of cortisteroids by esophageal carcinoma. 2. Pseudohyperparathyroidism caused by the same tumor. 3. Presentation of hypokalemic alkalosis as the initial manifestation and lack of specific gastrointestinal symptomatology of esophageal carcinoma.
