Objective:
To study the histopathological classification of eyelid tumor.
Method:
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.
Conclusion:
The classification and differentiation in type of eyelid tumor are beneficial to the histopathological diagnosis.
