[New studies and considerations on the pathology of the primate skull. A contribution to the "Gundu" problem].
The problem of 'Gundu' in primates is discussed. Cases of so-called 'Gundu' in the literature, two cases in Gorilla and one in Lagothrix, are dealt with. Histological and X-ray techniques are used. One case (Lagothrix) represents the so-called simian bone disease, which is metabolic disorder and is due to a secondary nutritional hyperparathyroidism. The other two cases (Gorilla) show symmetrical bony tumors of the maxilla. The origin  is uncertain. Gundu, Paget's disease and primary hyperparathyroidism Recklinghausen have not been observed  in primates so far.
