Pituitary adenoma-associated with Schöpf-Schulz-Passarge syndrome.

Hidrocystomas are benign cystic skin tumours of sweat gland origin which often involve the eyelids but are usually solitary. We report the case of a middle-aged man with multiple bilateral eyelid hidrocystomas, palmoplantar keratoderma, hypodontia and nail dystrophy, in keeping with a diagnosis of Schöpf-Schulz-Passarge syndrome, an exceedingly rare ectodermal dysplasia. Hyperprolactinaemia was found on testing, and radiology revealed an incidental prolactinoma. Raised serum prolactin has not been previously associated with Schöpf-Schulz-Passarge syndrome. The significance of raised serum prolactin in the context of multiple eyelid hidrocystomas is discussed.
