We describe an apparently newly recognized postnatal-onset obesity syndrome with short stature, mental deficiency, hypogonadism, micropenis, contractures of the fingers, and cleft lip-palate. Comparison is made with other postnatal-onset obesity syndromes, particularly Vasquez syndrome and Urban syndrome. The cause of our patient's syndrome is unknown at present. We encourage the reporting of other cases to help clarify whether our patient represents a separate entity.
