title: Chondroid syringoma of the eyelid.
abstract: An 81-year-old man underwent excisional biopsy of a big cylindric painless mass of the right lower eyelid, which had been present for over 23 years. Histopathologic and immuno-histochemical examination showed a chondroid syringoma, an uncommon benign neoplasm of possible eccrine sweat gland origin, which occurs generally in the head and neck skin. In the eyelids, it has been previously described as a small nodule in the upper lid. Surgical excision of these tumours is recommendable because malignant transformation is possible, although rare.
