Hereditary benign intraepithelial keratosis

(1) Causes of the disease

Hereditary benign intraepithelial keratosis is caused by autosomal dominant inheritance.

(two) pathogenesis

Department of autosomal dominant hereditary disease, the pathogenesis is still not very clear, histopathological manifestations of epidermal hyperplasia, acanthosis hypertrophy, vacuole-containing spine cells and benign keratinocytes. The epidermis is mainly waxy eosinophils.

Histopathology: manifested as epidermal hyperplasia, acanthosis hypertrophy, vacuole-containing spine cells and benign keratinocytes, the epidermis is mainly wax-like eosinophils, this cell is called intracellular cells.

Diagnosis and differentiation of hereditary benign intraepithelial keratosis

According to the clinical manifestations, the characteristics of skin lesions and histopathological features can be diagnosed. Generally not confused with other diseases.
