title: [Subepidermal calcified nodule (calculus) of the eyelid].
abstract: A 9-year-old boy presented with a painless hard tumor in the right lower lid. It had grown slowly since 12 months. Three months before presentation cryotherapy was administered by a dermatologist because of a presumed wart. Both eyes were normal. Clinical differential diagnosis included a keratoakanthoma and a wart. Excisional biopsy was performed. Histology revealed granular deposits which stained positive with hematoxylin-eosin and von Kossa stain. Though a secondary (dystrophic) calcinosis of the lid following cryotherapy could not be ruled out a diagnosis of an idiopathic subepidermal calcified nodule (calculus) of the lid was established.
