Benign eccrine hidradenoma in the third trimester of pregnancy

Abstract EN

During pregnancy, elevated levels of estrogen and progesterone stimulate melanogenesis.

High levels of circulating hormones also cause vascular changes and alter hair growth cycles.

Common skin tumors in pregnant women include angiomas, Sebaceous hyperplasia, dermoid cyst, Seborrheic Keratoses and pyogenic granuloma, which occurs primarily in the gingiva, and molluscum fibrosum gravidarum, or skin tags.

Here we report a case of a patient diagnosed with a CCH on the lateral chest wall in the third trimester of pregnancy.

Knowing the cytological features of primary skin adnexal neoplasms helps distinguish them from cutaneous metastases which can be aggravated during pregnancy.

This case adds to the growing body of evidence that suggests that pregnancy may contribute to the development of eccrine sweat apparatus tumours.
