%X <B>OBJECTIVE: </B>To describe a series of cases of basal cell carcinomas of the eyelid.<BR><B>METHODS: </B>A descriptive and retrospective study was conducted by reviewing the medical outcome, histopathological history, and photographic images of 200 patients with basal cell eyelid carcinomas. All were treated in the Herzog Carl Theodor Eye Hospital in Munich, Germany, between 2000 and 2013.<BR><B>RESULTS: </B>In the present study, it was found that females are more affected than males. The mean age of presentation of the tumor occurred at the age of 70 years. In 50% of the cases the tumor was found on the lower lid, especially medially from the center of the lid. The lid margin was involved in 47% of all tumors. The mean diameter was 9.2mm. The recurrence rate after surgery with histologically clear resection margins was 5%. There was a significant relationship between tumor diameter and age. As tumors where located farther away from medial and closer to the lid margin, they became larger.<BR><B>CONCLUSIONS: </B>There is a predominance of women affected by this tumor. This may be related to the fact that the sample was taken from those attending an oculoplastic surgery clinic, where there are generally more women than men attending. The formation of basal cell carcinomas increases with age. The infrequent involvement of the upper lid could be explained by the protection of the the eyebrow. The frequent involvement of the lower lid may be due to the light reflection (total reflection) by the cornea on the lower lid margin. Also chemical and physical effects of the tears may be more harmful on the lower lid. Patients tend to ask for medical help when they are females, younger, when the tumor is closer to the medial canthus or when the tumor is away from the lid margin.
