Esophagus cancer and IgA deficiency in a patient with Dubowitz syndrome: a case report.

Dubowitz syndrome was first described in 1965 by the English physician Dr. Victor Dubowitz. This genetic disorder causes growth retardation both before and after birth. It is primarily diagnosed through the distinctive facial features of affected individuals, including a small triangular-shaped face with a high forehead and wide-set, slitted eyes. The main method of diagnosis is through identification of facial phenotype. Esophageal mass biopsy revealed squamous cell carcinoma type. Both malignancy and IgA deficiency have been reported literature in patients with Dubowitz syndrome. However, Esophagus cancer has not been reported among the malignant tumors. Herein, we reported a patient with Dubowitz syndrome, IgA deficiency and Esophagus cancer.
