Introduction Demographics Causes Clinical features Diagnosis Differential diagnoses Treatment
Hypergranulotic dyscornification is a reaction pattern seen on histology following excision of a benign keratotic skin lesion.
Hypergranulotic dyscornification has been rarely reported. In the one large pathology series, there was a female predominance of almost 2:1. All reported cases have been adults with a mean age at diagnosis of 57 years. There is no information regarding racial distribution at this time.
The cause of hypergranulotic dyscornification is unknown. Theories include a possible keratin mutation or other disorder of keratinisation and epidermal maturation.
Hypergranulotic dyscornification has almost exclusively been seen in lesions described as:
Most have been excised from the lower limbs, followed by the trunk. Upper limbs, head, and neck are less commonly reported sites.
Hypergranulotic dyscornification is diagnosed on histological examination of an excised skin lesion [see Hypergranulotic dyscornification pathology].
As hypergranulotic dyscornification is only diagnosed after excisional biopsy, further treatment is not required. All reported lesions showing hypergranulotic dyscornification have been benign to date.
