What does a ring-shaped granuloma look like?
What do doctors think?
First of all, dermatologists call this disease "benign." So, despite the gaps in knowledge about the causes and mechanisms of development of this state, it will not bring significant damage to the body, there will be no serious local and systemic pathological processes. Ring-shaped granuloma in children is carefully studied by many scientists and doctors. Previously, its cause was thought to be metabolic disorders, diabetes, tuberculosis, and even prolonged exposure to sunlight. However, modern theories put immune system disorders and genetic susceptibility to certain “shifts” in metabolism in the first place.
How does the disease develop?
The first sign that a child develops an annular granuloma - the appearance of dense nodules towering above the skin. The “favorite” places of their formation are the back surface of the hands and feet, but with the same frequency they also affect the skin of the face, upper and lower extremities, chest, back or abdomen.The size of the elements may not exceed 1 mm, and they do not cause itching or pain. Further, the individual elements begin to merge into half rings or rings of the usual “skin” color, and sometimes - pale pink or grayish-red. The skin in the center of the ring usually falls, however, it can be at a normal level. The diameter of the elements at the same time begins to increase, it can even reach the size of the palm of the child. The total number of rings can be from 1-3 to several dozen. However, the latter occurs mainly in adults, and in children the disease has a localized form in more than 90% of cases. Note that in children under 6 years of age, the subcutaneous form of granuloma is quite common, having the appearance of barely pronounced nodules located deep in the skin. In addition to the skin of the legs and forearm, the subcutaneous annular granuloma is often found on the scalp.
What to do?
There is no reason to panic. As mentioned above, it is a benign condition with a favorable prognosis; moreover, it often disappears on its own, without medical intervention. But we must be prepared for the fact that after a certain period of time (from one to two months to several years), the annular granuloma may appear again.In any case, consultation of a dermatologist and a pediatrician is required to clarify the diagnosis (similar elements on the skin can be in other diseases). Sometimes, with an unclear diagnosis, histopathological examination of the skin at the site of the lesion may be required.
How to treat?
If the child has an annular granuloma, the treatment will be local or systemic. Locally, children are prescribed hormonal (corticosteroid) ointments, which have an anti-inflammatory and antiallergic effect. Systematically used phototherapy, and above all - PUVA therapy (using a photoactive substance in conjunction with irradiating the skin with long-wave ultraviolet), has proven itself quite well. This treatment is carried out in special cabins, it is completely safe and very effective.
