Syringoma presenting as milia.
We present two unrelated patients with numerous infraocular milium-like lesions that histologically revealed syringoma with many overlying keratin cysts in the papillary dermis. A Fontana-Masson stain revealed no melanin-containing cells in the keratin cyst walls, suggesting that they originated from eccrine ductal structures. A classification of the clinical variants of syringoma is presented.
