Difference to basal cell carcinoma
Basal cell carcinoma is an important differential diagnosis to sebaceous gland hyperplasia. A basal cell carcinoma is a skin cancer that mainly affects older people and occurs after years of exposure to sunlight. Furthermore, genetic factors also play an important role in its development.
Basal cell carcinoma can be very similar to sebaceous gland hyperplasia, which is why a precise examination is very important for differentiation. Basaliomas are often reddish and show a central dent, which however, in contrast to the dent of sebaceous gland hyperplasia, resembles a crater. This crater may be ulcerated.
This means that small injuries are present in the crater. Basaliomas are often found on the nose or eyelids. They grow very slowly and usually develop over several years.
