Ectopic Hidradenoma Papilliferum

Abstract EN

Hidradenoma papilliferum is a rare tumor that occurs almost exclusively in females on the anogenital area.

Rare cases of ectopic (nongenital) hidradenoma papilliferum have been described.

The lesions usually present as an asymptomatic slow-growing, red, firm, mobile, well-delimitated nodule that grows for a long time before resection.

We describe a case of an 26-year-old man that presented with an enlarging nodule on his right eyelid.

The histological findings revealed a hidradenoma papilliferum.

So far, among the very few reports of ectopic hidradenoma papilliferum, only a very small number were localized to the eyelid.
