A rare endocrine disease characterized by unusually tall stature (with rapid growth velocity), occurring before closure of the epiphyseal growth plates, due to excessive growth hormone (GH) caused by a GH-secreting pituitary tumor or from pituitary hyperplasia. Additional associated features may include pubertal delay, visual defects, headache, excessive appetite, hyperhidrosis and menstrual irregularity, as well as variable manifestations characteristic of acromegaly, such as prognathism, coarse facial features and large hands/feet in adolescents.
Scaphocephaly is a subtype of dolichocephaly where the anterior and posterior aspects of the cranial vault are pointed (boat-shaped). Scaphocephaly is caused by a precocious fusion of sagittal suture without other associated synostosis.
