Some people feel itchy, others do not. After contact with detergents such as laundry detergent, detergent, etc., the skin starts to peel off immediately afterwards, and the layers stack up, and can even eventually reveal bright red tender skin, or the palms of the hands are rough like woolen glass, often cracking and painful in winter. Do you have similar symptoms to the above that bother you? In the dermatology clinic, we often encounter patients with the above-mentioned confusion, who often do not take the disease seriously at the beginning, and apply some creams that do not even have a clear name and efficacy, until they repeatedly do not get better, then they rush to see a doctor. So what exactly is this disease? In fact, this is a common manifestation of a variety of skin diseases can appear, although the problem is small, but also often bring some unnecessary trouble. Generally patients do not have professional medical knowledge, may not be able to make a clear diagnosis and identification, then the use of drugs is blind, the treatment is not effective is to be expected. What are the specific diseases that can have such symptoms and how to treat them? Here, we will give you readers a brief introduction one by one: 1, exfoliative keratolytic disease: patients often sweaty palms, more in the warm season suddenly in the palms of both hands, the initial pinhead-sized white spots, gradually expand around, similar to dry small blisters, easy to break naturally or by tearing into thin paper-like scales, a collar-like layers of peeling, can reveal thin and tender skin, generally no itching. After a few weeks or months, the skin can be completely restored to normal, but next summer and autumn, it will recur again. 2, progressive finger and palm keratoderma: this disease mostly occurs in post-pubertal women, often occurring symmetrically on the palm surface of both fingers at first, and then gradually expanding to the palm, and can even spread along the lateral edge of the fingers to the back of the hand. The skin is dry, rough, wrinkled, mildly red and flaky, the palm surface skin shows broken glass-like superficial cracks, or finger end skin tight, even the fingers can not be completely straight, often cracked and painful in winter. As the patient in contact with soap powder, detergent and other alkaline detergents often aggravate the symptoms, it is also known as rich hands, housewife hands. 3, sweat blisters: also known as sweating bad eczema, common in summer, manifested as subcutaneous deep in small blisters, millet to large rice grain size, slightly higher than the surface of the skin, often without redness around, more symmetrical occurrence in the palm of the hand or finger side edge.

In acute or subacute eczema, the palms of the hands often appear clusters of red papules or small blisters with erythematous edges, intense itching, scratching out yellowish exudate, followed by superficial vesicles or crusts, and mostly symmetrical occurrence. The acute inflammation decreases after a long time or after treatment, and it is manifested by gradual thickening of the skin, deepening of the skin lines, pigmentation, and easy cracking in winter, or with bleeding and pain. When washing hands and laundry, the condition is more likely to worsen and become stubborn and difficult to treat because of frequent contact with soap, detergent, and hot water. 5. Ringworm: This disease is caused by a fungal infection, and most patients are infected by scratching because they first have tinea pedis or ringworm. Therefore, unlike the above-mentioned diseases, this disease often starts on one hand and slowly spreads to the other hand. The blistering type begins with pinhead-sized blisters on one part of the palm of the hand, which appear in clusters or are sparsely distributed, have thick, shiny walls, are pruritic, dry up and then flake, and gradually spread and expand to form a ring-shaped lesion. The keratosis type is mostly developed from the blister type, manifesting as diffuse redness and thickening of the palm surface, deepening of the skin lines, rough, dry and flaky skin, easy to crack in winter, deep and bleeding fissures, painful. The biggest point of differentiation between this disease and the above diseases is that the fungus can be detected from the skin flakes of this disease under the microscope. After understanding the characteristics of each of the different diseases mentioned above that can cause palm desquamation, let’s talk about their treatment. Among the above diseases, tinea cruris is the one with the clearest cause, and it can be diagnosed as tinea cruris by examining the flakes that fall off under a microscope and finding fungus, and most of them can be cured with oral (such as terbinafine, itraconazole, etc.) or topical (such as miconazole cream, bifenazole cream, etc.) antifungal drugs. Apart from this, the etiology of the remaining diseases is not very clear at present, and the treatment is mostly symptomatic.
