Conditions that can be mistaken for GGI with differentiating features

Differential diagnosis of GGI	Differentiating features
Jacquet’s erosive dermatitis	Tender punched out painful ulcers in ages above 6 months, resulting from lack of hygiene and infrequent diaper changing, no use of medications
Allergic contact dermatitis	Erythematous papules and patches resolving usually with empirical treatment of steroids rather than persisting
Candidiasis	Erythematous patches favoring the folds, with scattered satellite lesions, positive culture, responding to antifungal
Tinea corporis	Usually single or few annular lesions(but maybe plaques) with scales. KOH shows fungal elements, cultures may be positive, responds well to antifungals
Psoriasis	Erythematous plaques in the diaper area. May have positive family history of psoriasis, responds partially to empirical steroids
Seborrheic dermatitis	Other common sites involved would be the scalp(cradle cap) and eyes brows.
Langerhans histiocytosis	Unwell infant, organomegaly, seborrheic dermatitis like lesions on the scalp, persistent diaper rash, petechia, pancytopenia, diagnostic biopsy(histiocytic infiltrate)
Secondary syphilis	May present as puched out ulcers, papules or plaques, as well as condyloma accuminata. FTA Abs positive
