Keksa Purpura (Senile purpura) - bilak va qo'llarning orqa qismida paydo bo'ladigan yirik, 1-5 sm, to'q binafsha‑qizil ekhimozlar (ecchymoses) bilan tavsiflangan teri kasalligi. Purpurik lezyon terining biriktiruvchi to'qimalariga quyosh ta'sirida shikastlanganidan kelib chiqadi. Hech qanday davolanish shart emas. Lezyonlar odatda 3 haftagacha yo'qoladi.
Solar purpura ("Senile purpura") is a skin condition characterized by large, sharply outlined, 1- to 5-cm, dark purplish-red ecchymoses appearing on the dorsa of the forearms and less often the hands. It is caused by sun-induced damage to the connective tissue of the skin.
Bu holat keksa odamlarda juda tez-tez uchraydi va qo'lni qattiq ushlab tursa, u osonlikcha ko'karadi. Steroidli malham qo'llanilmasligi kerak.
Aktinik purpura qon terining chuqur qatlamlariga oqib tushganda paydo bo'ladi. Bu ko'pincha terisi yupqalashgan va qon tomirlari zaif bo'lgan keksa odamlarda uchraydi, ayniqsa ular quyoshda ko'p bo'lgan bo'lsa. Actinic purpura results from the extravasation of blood into the dermis. This phenomenon is due to the skin atrophy and fragility of the blood vessels in elderly individuals, which is exacerbated by chronic sun exposure.
