What Is Granuloma Annulare?
10. Similar Conditions
There are two conditions that are similar in symptomology to granuloma annulare. The first of these, tinea corporis, presents as an itchy skin rash and most frequently occurs on the arms and legs. It is characterized by ring-shaped lesions that are reddish in color. The potential exists for scaling as well. A fungal infection causes tinea corporis.
The second disorder is called eruptive xanthoma. Doctors differentiate it from GA due to the difference in coloration of the histiocyte cells. This color difference can be seen through a microscope. Eruptive xanthoma also affects the entire body, which is rare for granuloma annulare.
