Psoriasis lesion patterns can take many forms: in the acute phase the lesions tend to be punctate, bright red, and itch more pronounced. The lesions can occur symmetrically on any part of the body. The initial symptoms of psoriasis tend to occur on the elbows, knee extensors, and head. Finger (toe) nails and mucous membranes may also be invaded in a few patients. Psoriasis on the hands (palms): The rash of psoriasis can be widespread over any part of the body, including the palms and plantar areas, but it is generally rare and can coexist with rashes on other parts of the body or appear alone on the palms and plantar areas. It is a keratotic patch with distinct borders, with a thicker center and thinner borders. The patch may be dotted with white scales or dotted depressions, and is easily confused with “calluses” or keratotic dermatoses of the palmoplantar area when there are no scales. Psoriasis of the palmoplantar area should be distinguished from “callus” and so on. The latter is often caused by long-term friction and pressure, and is a hard yellow keratinous plaque, often confined to the front of the palm or the front of the metatarsal side, the heel, etc. It has no conscious symptoms, is not red, does not flake, and is common in manual work or long-term outdoor workers. It is important that you understand the symptoms of psoriasis on the hands. In addition, ruptured palmoplantar psoriasis is sometimes easily misdiagnosed as chapped eczema. The disease usually first appears as small red patches, papules, and blisters. Under the action of external factors, diffuse infiltrative hypertrophy with indistinct borders appears. Keratosis pilaris, on the other hand, can usually isolate pathogenic bacteria and is easily distinguished from psoriasis of the hands and feet. One of the basic principles of treating psoriasis with TCM is to find the cause of psoriasis and treat it in a targeted manner. Psoriasis treatment prevents the onset of psoriasis by giving full play to its important role and making reasonable internal adjustments, thereby inhibiting its synthesis and breeding of diseased cells and removing the lesions.
