Few natrually occurring tumors have been reported in primates. A spherical mass was noticed on the medial aspect of the thigh and caudal abdomen of a 15-year old female Perodicticus potto. The mass was surgically removed and the recovery was uneventful. Histological examination provided the diagnosis of myeloliposarcoma. Thirty-two elements were detected by chemical analysis. These are Na, K, Rb, Cs, Li, Cu, Ag, Be, Mg, Ca, Sr, Zn, Cd, Hg, B, Al, Ga, Si, Sn, Ti, P, Bi, V, S, Se, Mo, F, Cl, Br, Fe, Co and Ni. It has been proposed by some that tumor tissue tends to be chemically similar to embryonic tissue. Bromine is unexpectedly high in the potto tumor, in other tumor analyses reported in the literature, as well as in the only available embryonic tissue from the female potto, a placenta. Data are presented that lend credence to the speculation that Br may have a hitherto unexpected function in reproduction.
灵长类动物中自然发生的肿瘤鲜有报道。在一只15岁雌性金熊猴的大腿内侧和腹部尾部发现了一个球形肿块。该肿块通过手术切除，恢复过程顺利。组织学检查诊断为骨髓脂肪肉瘤。化学分析检测到32种元素。它们是钠、钾、铷、铯、锂、铜、银、铍、镁、钙、锶、锌、镉、汞、硼、铝、镓、硅、锡、钛、磷、铋、钒、硫、硒、钼、氟、氯、溴、铁、钴和镍。一些人提出肿瘤组织在化学上往往与胚胎组织相似。在金熊猴肿瘤中，溴含量出奇地高，在文献报道的其他肿瘤分析中以及在唯一可得的来自雌性金熊猴的胚胎组织——胎盘中也是如此。所提供的数据支持了这样一种推测，即溴可能在生殖过程中具有迄今未被发现的功能。
