What is Granuloma Annulare?
Granuloma annulare is a long-term skin condition characterized by elevated, red to skin-colored lesions that form circular patterns typically emerging on the hands, feet, elbows and knees. It is common in children and adults and to some extent more common if the female population and is also associated more often with diabetes mellitus.. The condition was first described in medical literature by Thomas Colcott Fox and was coined by an English dermatologist named Henry Radcliffe Crocker. It can be categorized into different types, namely, localized, generalized, patch-type, subcutaneous, perforating and HIV disease-related.
Apart from the noticeable rash, Granuloma annulare is commonly asymptomatic in nature. But in some cases, the rash burns and itches. Firm papules may appear due to the clustering of T cells underneath the skin. Irregularly, multiple rings can be found.
For the reason that Granuloma annulare generally produces no symptoms, treatment is not necessary apart from cosmetic purposes. If treatment is desired, it is helpful to seek advice from a dermatologist. For rapid clearing of the rash, very strong steroid creams and ointments can be sometimes applied. Subdermal steroidal injection directly on the ring patterns is also effective. Freezing the bumps with the use of liquid nitrogen may not be effective. For serious and widespread cases, an ultraviolet light therapy and other potent methods are needed.
