Multiple Eyelid Cysts (Apocrine and Eccrine Hidrocystomas, Trichilemmal Cyst, and Hybrid Cyst) in a Patient With a Prolactinoma
A 53-year-old man presented with smooth-domed, variegated cysts (polycystic disease) of all 4 eyelids, worse on the left side. Some of the cysts were clear, while others were creamy-white colored. In addition, multiple, very fine vesicopapules were noted along the eyelid margins. Histopathologic examination revealed a trichilemmal cyst, several pure apocrine hidrocystomas displaying multiple chambers, a hybrid cyst, and many small eccrine cysts of the deep dermis. The apocrine lesions, including the small ones at the eyelid margins, predominated. Smooth muscle actin sometimes positively stained outer myoepithelial cells in some of the apocrine cysts, which helped to distinguish them from eccrine cysts. Most noteworthy was the fact that the patient had been diagnosed with a prolactinoma 20 years earlier. There is only 1 previous report of multiple apocrine cysts and an antecedent prolactinoma in the dermatologic literature. This syndrome should be separated from that of Schöpf–Schulz–Passarge, which manifests multiple small eyelid apocrine cysts and other ectodermal dysplasias without any association with neoplasia, and from that of focal dermal hypoplasia (Goltz–Gorlin) syndrome with apocrine cysts but again without neoplasia.
