One month before this visit, she had undergone an incision biopsy of her labial mass at the provincial hospital, and the pathological report indicted only apocrine hidrocystoma
. Nevertheless, the mass had increased in the size with accompanying progressive pain.
Apocrine hidrocystoma (AH) has been described as an adenomatous cystic proliferation of the secretory coil of apocrine glands .
A final diagnosis of apocrine hidrocystoma was established.

Other cystic lesions included in the differential diagnosis of eccrine hidrocystomas are follicular cysts, epidermal inclusion cysts, hemangioma, lymphangioma, apocrine hidrocystoma and eccrine acrospiroma.
Cases of 'orbital apocrine hidrocystoma' have been reported in the literature by Valenzuela and Heathcote (6), Ssi-Yan-Kai and Pearson (7), Vignes et al.
The sweat glands tumors are comprised of chondroid syringoma, eccrine poroma, nodular clear cell hidradenoma, apocrine hidrocystoma, and syringocystadenoma papilliferum (Figure 1).

INTRODUCTION: Apocrine hidrocystoma
is a lesion produced by cystic dilatation of apocrine glands, usually presents as a solitary lesion around the eye.
on the penis of a 40-year-old man.
Differentiation from apocrine hidrocystomas
poses a problem both clinically and histologically.
Eccrine and apocrine hidrocystomas
are eccrine- and apocrine-derived cysts, which most investigators consider to be ductal malformations and not benign neoplasms.
