Diagnosis of Numulatory Dermatitis
Numulatory dermatitis can be easily identified through checking the skin with dermatitis. The doctor can also do an allergy test to check if the patient's skin has an allergy that triggers dermatitis. Some diagnostic methods that can help diagnose numulatory dermatitis are:
- Swabbing and bacterial culture. Swabbing is done by taking exudate fluid that comes out from the part of the skin that has numularis dermatitis. This method aims to detect whether there is a bacterial infection in the area of dermatitis. The bacteria that generally appear in the area of dermatitis include Staphylococcus aureus , Helicobacter pylori , and Giardia spp. Especially if the patient has a history of infection with these pathogens.
- Skin biopsy. Skin biopsy is done by taking skin tissue in the part that is inflamed, then observed using a microscope. Skin biopsy can distinguish microscopic numularis dermatitis from other diseases, such as tinea corporis, psoriasis , and T-cell lymphoma.
