Diagnosis
Differential diagnosis
Differential diagnosis:
Acute eczema in the back of the ear, groin, perianal, and cervical sac should be identified with rubbing. The latter occurs mostly in obese infants, in summer or in children with drooling and diarrhea, and does not pay attention to local skin cleansers. Sometimes it needs to be differentiated from contact dermatitis. The disease has a history of contact. Skin damage occurs at the boundary of the contact site. Patch tests can be used to identify contact factors. However, in the neonatal period, patch tests are often difficult to show.
When eczema occurs in the diaper area or in the perianal, underarm, etc., it must be differentiated from diaper dermatitis and candida infection. The former is located in the diaper area of the perineum, the inside of the femur, clear diffuse erythema or a little herpes. Wash the diaper frequently and keep the diaper area clean and dry. Candida infection is a pale red patch and a flat small papule, with a raised edge and a clear boundary. The periphery is scattered with small patches and a small amount of scales on the edges. It is easy to find fungi, and often combined with thrush and angular keratitis.
