ABSTRACT
PURPOSE:
To clarify the incidence and demographic characteristics of malignant eyelid tumors diagnosed in a single institute in Japan. STUDYDESIGN:
Retrospective, observational case seriesMETHODS:
Patients with malignant eyelid tumors diagnosed histopathologically at Tokyo Medical University Hospital between 1995 and 2019 were reviewed retrospectively. The incidence and demographic profile of malignant eyelid tumors were analyzed. The number of benign eyelid tumors diagnosed histopathologically during the same period was also counted.RESULTS:
A total of 412 patients with histopathologically proven malignant eyelid tumors were included. The most common malignant eyelid tumor was sebaceous carcinoma (n = 180, 44%), followed by basal cell carcinoma (n = 148, 36%), squamous cell carcinoma (n = 35, 9%), lymphoma (n = 28, 7%), Merkel cell carcinoma (n = 11, 3%) and others (n = 10, 2%). Mean age of all patients with malignant eyelid tumor at the time of diagnosis was 71.0 ± 13.0 years. For sebaceous carcinoma, the proportion of female patients was significantly higher than that of male patients (P = 0.0283) and the proportion of involvement of upper eyelid was significantly higher than that of lower eyelid (P = 0.0001). On the other hand, there was no sex predominance in basal cell carcinoma and squamous cell carcinoma. The proportion of involvement of lower eyelid was significantly higher than of upper eyelid in basal cell carcinoma (P = 0.001) and squamous cell carcinoma (P = 0.0012). There were 1433 patients with benign eyelid tumors accounting for 78% of all eyelid tumors during the study period.CONCLUSIONS:
Sebaceous carcinoma is the major malignant eyelid tumor in Japan and is more frequent in women than in men. Epidemiology of malignant eyelid tumors may be affected by the trend of population age structure associated with the recent population aging.Palavras-chave
