Introduction

In general, bovine skin癣 refers to psoriasis. Whether psoriasis lesions grow symmetrically needs to be determined based on specific circumstances. Under normal conditions, they typically grow symmetrically; however, if there are other accompanying lesions, the growth pattern may not be symmetrical. The causes of psoriasis are usually related to family genetics, long-term smoking, prolonged mental stress, inflammatory infections, and other factors.

Generally speaking, cowhide癣 refers to plaque psoriasis. Plaque psoriasis typically presents symmetrically, although specific manifestations may vary among individuals. If discomfort occurs, timely medical treatment is recommended. Detailed analysis is as follows:

Plaque psoriasis is a chronic autoimmune disease, with typical symptoms including red patches and thick scales. In most cases, the disease exhibits symmetry, meaning that if symptoms appear on one part of the body, similar symptoms may also develop on the corresponding part on the other side. This symmetry may be due to abnormal immune responses or the impact of psoriasis on epidermal cell differentiation and proliferation.

However, due to individual differences, varying triggering factors, or differences in disease progression stages, some patients may experience more severe symptoms on one side of the body than the other, or certain lesions may appear in one specific area without corresponding involvement on the symmetrical side.

If related symptoms occur, prompt medical consultation is recommended so that a doctor can make a diagnosis and provide treatment based on the patient's specific condition. In daily life, maintaining healthy habits and a positive mindset, as well as avoiding possible triggering factors, can help control the disease and improve quality of life.
