In humans, apocrine gland tumours encompass a heterogeneous group of uncommon neoplasms with varied and unpredictable biological behaviour. They can be slow-growing lesions, recur after excision, produce lymph node metastasis in up to 50% of cases or lead to tumour-related death. We document a malignant scent adenocarcinoma in a wedge-capped capuchin monkey (Cebus olivaceus). Immunohistochemical labelling revealed complete absence of myoepithelial cells, a finding usually considered a hallmark of malignancy in humans; however, after a 2-year follow-up, the neoplasm had not recurred. This is the first detailed report of the pathology of a spontaneous scent (apocrine) gland adenocarcinoma in a non-human primate.

在人类中，顶泌腺肿瘤涵盖了一组异质的罕见肿瘤，它们的生物学行为各不相同且无法预测。它们可能是生长缓慢的病变，切除后会复发，在多达50％的病例中会发生淋巴结转移，或导致与肿瘤相关的死亡。我们在楔形帽卷尾猴（Cebus olivaceus）中记录了恶性气味腺癌。免疫组织化学标记显示完全没有肌上皮细胞，这一发现通常被认为是人类恶性肿瘤的标志。然而，经过2年的随访，该肿瘤并未复发。这是非人类灵长类动物中自发性（腺嘌呤）腺癌病理学的第一个详细报告。
