Nummular dermatitis is a chronic and inflammatory skin condition that occurs in men more often than it does in women. It is characterized by coin-shaped lesions in the skin. This condition can appear at any age but it is usually seen in the 5th or 6th decade of life.
The exact cause of this disease is not known but it is closely related to conditions that involve dry skin and/or persistent skin trauma.
This condition is also known as Nummular Eczema and Discoid Eczema. The diagnosis of this condition needs to be made by a trained medical professional as it is hard to distinguish from other skin conditions. Here are 10 of the most common signs and symptoms associated with nummular dermatitis.
Symptom #1: Round Or Oval Lesions
The name nummular or discoid dermatitis comes from the circular shape of the lesions. This is the most common symptom associated with this disease but it is important to know that many other conditions can cause the same pattern.
The rash is usually described as red or violaceus papules (spots) on the surface of the skin. Later on, the lesions can coalesce to form larger plaques.
