Silica granuloma of a lymph node.
A case of silica granuloma in the submasseteric lymph node is presented. Sarcoidosis was excluded, as crystalline particles, with a double-refractile property, were seen in polarized light. The most probable cause was a delayed hypersensitivity reaction to silica from a lipstick cream introduced through a recurring angular cheilitis.
