Résumé
Isolated Schwannoma of the eyelid is an extremely rare benign neoplasm. Although it is believed to be present from birth, it show accelerated growth during the childhood or later in adults. These are generally asymptomatic or present as slowly enlarging, painless mass with progressive ptosis of the eyelid. I hereby report a case of giant schwannoma of size 3cmx3cmx2cm in the left upper eyelid of a 13 year old boy who developed progressive ptosis.
Résumé
PURPOSE: To assess the occurrence and characteristics of benign eyelid and conjunctival tumors. METHODS: We histopathologically analyzed 80 consecutive cases of benign eyelid (56 cases) and conjunctival (24 cases) tumors between April 2000 and November 2002. All eyelid and conjunctival tumors were confirmed histopathologically. Age, sexual distribution, occurrence and location were analyzed. RESULTS: The mean ages were 42.32+/-16.27 SD in benign eyelid tumors, and 29.71+/-18.60 SD in benign conjunctival tumors. The sexual distribution revealed 23 males and 33 females in benign eyelid tumors, and 12 males and 12 females in benign conjunctival tumors. About the location, lower lid was most frequent site of benign eyelid tumors, responsible for 27 (48.2%) of the 56 cases, and medial conjunctiva was the most frequent site of benign conjunctival tumors, responsible for 14 (58.3%) of 24 cases. Shave biopsy was performed in eyelid margin tumors. Excisional biopsy was performed in other eyelid tumors and conjunctival tumors. The frequency of benign eyelid tumors was noted in this order: intradermal nevi 25 cases (44.6%), seborrheic keratoses 9 cases (16.1%), and compound nevi 6 cases (10.7%), and frequency of benign conjunctival tumors was noted in this order: compound nevi 7 cases (29.2%), and intradermal nevi 6 cases (25.0%). CONCLUSIONS: From the Results of this study, we hope that this report provides a basic source for diagnosis and therapy of the benign eyelid and conjunctival tumors.
