Certain dermal appendage tumors have a striking histologic and clinical homology with some tumors arising from the salivary duct system. The dermal eccrine cylindroma is an exemplar. Arising from the eccrine ducts, this neoplasm is only occasionally found outside the head and neck, has a recurrence rate of over 40%, and in its malignant form is a high-grade carcinoma. Its counterpart in salivary glands, the dermal analogue tumor, manifests a histologic similarity, if not identity, also has a relatively high recurrence rate, and can also undergo malignant change.
某些皮肤附属器肿瘤在组织学和临床方面与一些起源于涎腺导管系统的肿瘤具有显著的同源性。皮肤小汗腺圆柱瘤就是一个例子。这种肿瘤起源于小汗腺导管，仅偶尔见于头颈部以外的部位，复发率超过40%，其恶性形式为高级别癌。其在涎腺中的对应物，即皮肤类似物肿瘤，在组织学上表现出相似性（即便不是完全相同），复发率也相对较高，并且也可发生恶变。
