Leprosy may be clinically confused with other systemic diseases such as systemic lupus erythematosus (SLE), rheumatoid arthritis, sarcoidosis, drug rash, granuloma annulare
, granuloma multiforme, pityriasis rotunda, erythema multiforme, and many others (2).
As I started to spout words of wisdom about his granuloma annulare
, he whipped out a tablet and started to type.
The differential diagnosis includes other parasites (uncinariasis, gnathostomiasis, strongyloidiasis, myiasis), dermatophytosis, phytophotodermatitis, erythema chronicum migrans, granuloma annulare
, and bullous impetigo.
The differential diagnosis of infiltrated annular lesions on the face and ears should include conditions such as tinea faciae, seborrheic dermatitis, granuloma annulare
, cutaneous lymphoma, sarcoidosis, and leishmaniasis.

However, because clinical appearance of these lesions can mimic various other skin conditions like tinea, ptyriasis alba, granuloma annulare
, eczema, annular psoriasis, sarcoidosis and mycosis fungoides, so the infection can be misdiagnosed.
The lesions which are maximally diagnosed in our study are leprosy, erythema nodosum leprosum, cutaneous tuberculosis, trichoepithelioma, Prurigo Nodularis, actinomycosis, granuloma annulare
, epidermoid cyst, syringoma, Jessener lymphocytic infiltrate, basal cell carcinoma (BCC), and metastatic carcinoma.
