What is the difference between sweat rash and eczema?

There is only one word difference between prickly heat and eczema, and the symptoms are also quite similar, but they are actually two completely unrelated diseases. The cause of prickly heat originates from inside the body, and is due to lesions in the lower layer of the epidermis caused by abnormal sweating, while eczema is a lesion on the surface of the skin caused by external conditions. Generally speaking, the latter is more serious than the former. Below, the editor will make a detailed and systematic comparison of the differences between the two skin diseases.

Overview

Dyshidrosis, also known as dyshidrotic eczema, is a blistering disease of the palms and soles of the feet. This disease often occurs in late spring and early summer, worsening in summer and healing on its own in winter. More common in teenagers.

Eczema is a skin inflammatory reaction with severe itching caused by a variety of internal and external factors. It is divided into three stages: acute, subacute and chronic. The acute phase has an exudative tendency, while the chronic phase has infiltration and hypertrophy. Some patients directly present with chronic eczema. The skin lesions are characterized by polymorphism, symmetry, itching and easy recurrence.

symptom

Typical skin lesions are small blisters located deep in the epidermis, the size of rice grains, hemispherical, slightly higher than the skin surface, with no inflammatory response, scattered or clustered on the palms, sides and fingertips, rarely on the back of the hands and soles of the feet, and often distributed symmetrically. The blisters contain clear serous fluid and generally do not rupture on their own. After drying, they peel off and reveal the red new epithelium, which is thin and tender and often painful. The surrounding skin was normal. This disease has varying degrees of itching and burning sensation.

Depending on the extent of skin lesions, it is divided into two categories: localized eczema and generalized eczema.

Localized eczema only occurs in specific parts of the body, and can be named according to the part of the body, such as hand eczema, vulva eczema, scrotal eczema, ear eczema, breast eczema, perianal eczema, calf eczema, etc.

Generalized eczema has multiple skin lesions that spread or scatter to multiple parts of the body. Such as nummular eczema, autosensitive eczema, and xerotic eczema.
