Cellular neurothekeoma of the eyelid in a 6-year-old boy.

We report the case of a 6-year-old boy who presented with an 18-month history of a left lower eyelid lesion that was refractory to medical management. The lesion was excised, and microscopic examination and immunohistochemistry revealed a cellular neurothekeoma. Clinical presentation of such lesions is similar to a chalazion or epidermal inclusion cyst. Cellular neurothekeoma is benign and has a low risk of recurrence after excision with clear margins. Cellular neurothekeoma of the eyelid is extremely rare, with only 5 previously reported cases. This is, to our knowledge, the first report of cellular neurothekeoma of the eyelid presenting in a boy.
