Reactive perforating collagenosis is a rare, familial, nonpuritic skin disorder characterized by papules that grow in a diameter of 4 to 6mm and develop a central area of umbilication to which keratinous material is lodged.[1][2] The cause of reactive perforating collagenosis is unknown.
Clinical Features[]
Inherited form[]
Keratotic papules measuring 1 to 6 mm develop on the extensor surface of the hands, the elbows, and the knees following superficial trauma. These lesions are painless. They appear as pin-sized lesions that grow to a papule of about 6mm in the following 3-5 weeks. They undergo spontaneous resolution in about 6-8 weeks leaving residual scarring. Lesions may recur throughout life. Cold weather is one of the factors known to trigger reccurences.[3]
Acquired form[]
In this form, keratotic papules develop on the trunk and extremities. These are commonly associated with pruritus. Lesions may or may not be related to superficial trauma.[3]
