A case is reported of a 24-year-old boy with history of arrested growth in 6th year, headaches, frequent urination, low blood pressure, hypotrichosis, undeveloped secondary sex characters, low basal metabolism, normal family history. He was regarded as an infantile proportionate dwarf owing to a neoplasm or cyst originating in residues of the ductus craniopharyngeus and causing injury to the adenohypophysis with resulting hypo-hypophysism, hypogenitalism and hypothyroidism.
