Symptom 1: pityriasis usually starts with some rose light erythema on the skin. This kind of initial erythema is called precursor spot, with thin scales. After one or two weeks of onset, erythema of different sizes will appear, symmetrically distributed. The shape of erythema is generally oval, and there will be pruritus of different severity. Generally, it mainly occurs on the trunk and limbs.

Symptom 2: pityriasis usually occurs in spring and autumn, mostly in young or middle-aged people. It has the characteristics of self-healing. Generally, it will subside in 4-8 weeks without recurrence. In addition, there are pityriasis rosea with red papules. This type of pityriasis rosea will have obvious itching, and may also be accompanied by fever.

Symptom 3: pityriasis is usually diagnosed by the precursor spot, predilection site, rash shape, pityriform scaly patch and other shapes. It is recommended that once diagnosed, it should be treated in time. Otherwise, if not treated in time or improperly, it is easy to leave unsightly pigmentation and affect the appearance of the skin.
