[Histopathological classification of 3,510 cases with eyelid tumor].
OBJECTIVE
To study the histopathological classification of eyelid tumor.


METHODS
The pathological specimens of 3,510 cases with eyelid tumor examined between 1953-1992 were retrospectively analyzed. RESULTS The 5 leading malignant lid tumors were basal cell carcinomas (430 cases, 37.6%), meibomian gland carcinomas (363, 31.7%), squamous cell carcinomas (216 cases, 18.9%), melanomas (56 cases, 4.9%) and malignant lymphomas (21 cases, 1.8%). The 5 leading benign lid tumors including papillomas (658 cases, 27.9%), pigmented nevi (578 cases, 24.4%), cysts (427 cases, 18.1%), angiomas (222 cases, 9.4% including 10 lymphangiomas) and verrucae (212 cases, 9.0%). Rare tumors of the eyelid included one case of each of the following tumors: reticulum cell sarcoma, adenocystic carcinoma, malignant mesenchymoma, mucinous adenocarcinoma, Bowen's disease, basosquamous carcinoma, basosebacious carcinoma, teratoma, granular cell tumor (myoblastoma), angiolymphoid hyperplasia with eosinophilia, osteoma, etc.


CONCLUSIONS
The classification and differentiation in type of eyelid tumor are beneficial to the histopathological diagnosis.
