Hi friends,Today, I came across an interesting sign,which I would like to share with you. It's none other than gottron's papules. Let's see little description about the gottron papules.
Description
Violaceous (violet-coloured) papular rash on the dorsal aspect of the interphalangeal joints.
Condition/s associated with
• Dermatomyositis
Mechanism/s
One histological study demonstrated lymphocytic infiltration, epidermal atrophy and vacuoles in the basal layer of the skin, in addition to other findings. The mechanism is unknown.
Sign value
Gottron’s papules are said to be pathognomonic for dermatomyositis; however, they are not present in all patients with the disease.
