Carcinogen-induced cutaneous neoplasms in nonhuman primates. 1976

J L Palotay, and K Adachi, and R L Dobson, and J S Pinto

Dimethylbenzanthracene (DMBA) combined with UV light, dodecylbenzene (DDB), or both was oncogenic when applied to the skin of nonhuman primates. Ten years after the cutaneous application of DMBA and a cocarcinogen, 2 groups of rhesus monkeys (Macaca mulatta) displayed dermal melanosis, papillomas, basal cell tumors, and mesodermal sarcomas (accompanied in one case by hepatic metastasis). One group had been painted for 15 months; the other, for 6 1/2 years. Eight years after the initiation of a 4-year regimen of biweekly applications of DMBA plus a cocarcinogen, papillomas, basal cell tumors, and basosquamous cell epidermal tumors with satellite lipomas were observed in galagos (Galago crossicaudatus). The same carcinogen applied to the skin of pottos (Perodicticus potto) caused death in 6 of the 7 animals within 9 weeks. Neoplasms occurred in 17 of the 19 primates that lived longer than 9 weeks after the cutaneous application of DMBA combined with either UV light or DDB.

D010212	Papilloma	A circumscribed benign epithelial tumor projecting from the surrounding surface; more precisely, a benign epithelial neoplasm consisting of villous or arborescent outgrowths of fibrovascular stroma covered by neoplastic cells.

D011323	Primates	An order of mammals consisting of more than 300 species that include LEMURS; LORISIDAE; TARSIERS; MONKEYS; and HOMINIDS. They are characterized by a relatively large brain when compared with other terrestrial mammals, forward-facing eyes, the presence of a CALCARINE SULCUS, and specialized MECHANORECEPTORS in the hands and feet which allow the perception of light touch.	Primate
D002280	Carcinoma, Basal Cell	A malignant skin neoplasm that seldom metastasizes but has potentialities for local invasion and destruction. Clinically it is divided into types: nodular, cicatricial, morphaic, and erythematoid (pagetoid). They develop on hair-bearing skin, most commonly on sun-exposed areas. Approximately 85% are found on the head and neck area and the remaining 15% on the trunk and limbs.
