Epidemiological Study of Seborrheic Keratosis among Egyptians in Great Cairo

Abstract

Background: Seborrheic keratosis is one of the most common benign epidermal tumors. Seborrheickeratoses are hyperkeratotic lesions of the epidermis, which often appear to be “stuck on” the surface of the skin. Cherry angiomas are very common acquired vascular skin lesions. Objective: To find any relation between seborrheic keratosis and cherry angioma. Patients and Methods: A total of one hundred male and female patients, presented with Seborrheic keratosis with or without associated cherry angioma (62% present CA & 38% absent CA), were included in the study. Full history taking and full examination was done between December 2015 and May 2017. Twelve biopsies were taken from 6 patients. Results: The age of the patients ranged from 18 to 88 years old. The male patients were (63%) and the female patients were (37%). 17% of patients complained of itching, 20% had positive family history of Seborrheic Keratosis, 75% had skin photo type III. Flat Seborrheic Keratosis was 49% of the cases. The most common site of SK was face (76%). The most common site of cherry angioma was abdomen (88.7%). The examination of the biopsies revealed no histopathological correlation between seborrheic keratosis and cherry angioma. Conclusion: The patient with seborrheic keratosis sometimes may have cherry angioma in adjacent to it or in a different site which didn't necessarily means that they have the same pathological origin.
