in the last two years, 4 times now, i feel an itching in my hand at a spot and think it it a mosquito bite. a little later a pea size lump forms and again a little later the lump disappears and i can see a subcutaneous bruise. (looks like blood leaked from "aneurysm" ) slight pain also as in a bruise. would appreciate some insight. thanks
Itchy localized rash can be due to allergic dermatitis, eczema, scabies, contact dermatitis, shingles, psoriasis, fungal infection like or Tinea. If there are itchy bumps then it could also be palmar warts, which is a HPV infection. Scratching can cause a wheal to form which looks like a bruise. It can also cause a fragile capillary to break. It is difficult to comment beyond this at this stage without examining the rash. Please consult a skin specialist. Take care!
