Rubinstein-Taybi syndrome is characterized by distinctive facial and limb features and is associated with several types of tumors. A 29-yr-old woman with this syndrome presented with a large, complex ovarian mass. She was subsequently diagnosed with a low-grade serous carcinoma of the ovary and an endometrioid adenocarcinoma of the uterus. Rubinstein-Taybi syndrome is an autosomal dominant, multiple congenital anomalies-mental retardation syndrome. Two genes, CREBBP and EP300, have been found to be associated with this disorder, although some cases do not have an identifiable cause. These genes code for proteins that acetylate histone tails, an epigenetic modification that serves to control transcription. They also serve as cofactors to several transcription factors and modulate p53. Although these patients have a predisposition to benign and malignant neoplasms, no malignant gynecologic neoplasm has been described thus far. Although no significant evidence linking CREBBP and EP300 to gynecologic malignancies has yet been found, some studies have suggested that hypoacetylation of histones may be involved in endometrial and ovarian carcinomas.
