Pigmented purpuric dermatosis in women

Pigmented purpura is a chronic skin disease characterized by purpuric papules and hemosiderin deposits. It is generally believed that it is related to capillary wall degeneration, and increased force and venous pressure are the main causative factors. Because of the recurring purpuric skin lesions, it is often easily misdiagnosed as allergic purpura. It includes the following three symptoms:

1. Idiopathic pigmented purpuric dermatosis is more common in men and can also occur in childhood. Initially, they appear as needle-sized red bruises, which then gradually gather together. The center is dark brown and spreads outward. New bruises continue to appear and are scattered around the old lesions. New and old bruises are mixed together. They usually occur around the calves and ankles. The duration varies, and they are sometimes accompanied by superficial varicose veins. Eventually, they can all be cured.

2. Telangiectatic annular purpura is more common in adolescents or young people, more common in women than in men. It is typically manifested by annular patches and macular dilatation of 1-3 cm in diameter, with pepper-like petechiae visible on the edges. It usually occurs symmetrically on the calves at first, and then slowly spreads upward to the thighs, buttocks, trunk and arms, and is often accompanied by varying degrees of itching symptoms. This disease generally has no symptoms. The rash can recur and last for months or years and tends to heal.

3. Familial pigmented purpuric dermatosis. This disease may be an autosomal dominant genetic disease that may occur in multiple members of a family. It is manifested by scattered red-brown macules that occur in childhood or adolescence. The individual macules are larger than those in idiopathic pigmented purpuric dermatosis and are arranged in an embedded pattern. The lesions are mainly located on the limbs and large wrinkles, develop slowly, and generally have no active symptoms. The color of the skin lesions can be brown, purple-brown and tan. Both men and women can be affected, but it is more common in women. There is slight itching, which recurs for a long time and generally has no active symptoms.

This type of pigmented purpuric dermatosis generally does not involve systemic organs, and relevant laboratory tests are all normal. Purpura rash has no significant effect on any treatment, and most of them can be alleviated and disappeared on their own, so special treatment is generally not required.
