Baby's back red spots

The baby's skin is very delicate, so it cannot be hurt at all. It is very likely to be infected with some skin problems, which may lead to complications and are quite harmful. When red spots appear on the baby's back, you should choose appropriate methods of conditioning and treatment according to the individual's physical condition. Generally, the red spots on the baby's back should be checked to see if it is lupus erythematosus, which may be an infection or a carried gene.

Identification of lupus erythematosus

This disease should be differentiated from other connective tissue diseases, bacterial or viral infectious diseases, histiocytosis X, malignant reticuloendotheliosis, thrombocytopenia, hemolytic anemia, various types of kidney disease, hepatitis, myocarditis, and nervous system diseases. It must be especially differentiated from lupus-like syndrome and neonatal lupus erythematosus syndrome.

1. Lupus-like syndrome

The most common of these is drug-induced systemic lupus erythematosus. This syndrome may be associated with some symptoms, signs, and laboratory test results similar to those of SLE, which are sometimes difficult to distinguish. The following situations are helpful for identification: history of taking related drugs, no obvious gender differences, mild clinical symptoms, visceral involvement, kidney disease, butterfly rash, oral ulcers, hair loss, and leukocytopenia, thrombocytopenia, hypocomplementemia are rare, anti-Sm antibodies and anti-n-DNA (FARR) antibodies are negative. The most important feature is that clinical symptoms and laboratory signs disappear after drug withdrawal, but reappear when the drug is used again. Sometimes antinuclear antibodies exist for a long time, and the prognosis is generally good.

2. Neonatal lupus erythematosus syndrome

This disease occurs in infants under 6 months old. Most of the mothers of the affected children suffer from SLE or other connective tissue diseases, and their serum contains RO antigen (Sjögren's syndrome A antigen) and La antigen (Sjögren's syndrome B antigen). The children have symptoms after birth, mainly manifested as congenital conduction block, lupus-like dermatitis, autolytic hemolytic anemia, and positive RO and La antigens in the body. In addition, it is often accompanied by congenital heart disease, various defects and endocardial elastic fiber hyperplasia, leukocytopenia and thrombocytopenia.

The typical manifestation of skin lesions is scaly and annular erythema, which is seen on exposed parts, such as the top of the head, neck and eyelids, and resembles disc-shaped erythema. This disease is a self-limiting disease. Blood abnormalities usually improve within 6 weeks, and skin lesions can disappear within 6 months. Except for children with heart disease, the prognosis is generally good. There are reports that adolescents may develop SLE, but the reason is still unclear.

The following are diseases and symptoms that are often encountered in clinical work and are easily confused. Because their treatment methods are different or even completely opposite, they need to be carefully distinguished.

1) Identification of CLE

ACLE and DLE occurring on the face need to be differentiated from seborrheic dermatitis. The latter, in addition to the erythematous lesions like the former, is also accompanied by enlarged pores and oily skin. Lesions can also occur on the tip of the nose, while LE lesions generally do not involve the tip of the nose. Disseminated DLE needs to be differentiated from multicentric reticulohistiocytosis. The latter has obvious joint symptoms and can lead to deformities. The lesions are mainly papules and nodules, and histopathology shows reticular histiocytic granulomas. SCLE also needs to be differentiated from psoriasis vulgaris. Chilblain lupus in CCLE also needs to be differentiated from chilblain and erythema multiforme.
