What Causes Rashes On The Lower Legs?

Husband has a rash on lower legs- he says it is heat rash, but it is flat, no bumps- splotchy, a little itchy. he is a police officer and wears a uniform and boots in the heat all day. Lots of time on feet for hours at a time. it almost looks like blood just coming to the surface of the skin.

Dermatologist 's  Response
Hello. Thank you for writing to us.

I will keep a likely possibility of Schaumburg's Disease. It is type of pigmented purpuric dermatosis.

Lesions in schaumburg's disease are distributed on bilateral lower limbs (commonly ankles and shins).
These consist of pinhead-sized reddish lesions, resembling grains of cayenne-pepper that further form irregular plaques of orange or brown pigmentation (owing to deposition of hemosiderin).
The patients are usually asymptomatic; slight itching may, however, be an associated feature.
Standing and walking for long hours is a factor in its occurrence.
Schaumburg's purpura is chronic and lesions either persist or extend with time.
They may clear spontaneously in a few after persisting for months Or years. Recurrences though are not uncommon.
No medical intervention is of proven benefit for the treatment of Schaumburg's disease.
Oral calcium dobesilate may be tried and may help resolve lesions. If not it surely arrests further progression.
I suggest that you visit a dermatologist for a confirmatory diagnosis as well as for the needful

Regards
