petechiae with edema

[deb657]

This makes the second time within a month that I've had petechiae come up on my ankles. They do not blanch when pressed.   I've suffered from edema of feet, ankles & lower leg during heat of summer for many years, but I've never had this before.  My doctor did a blood platelet test which came back normal after the first time.  What other tests should I ask him to do?  And should I be worried?

I have the same thing, started on feet (soft area behind toes on top) now on tibia area (started at ankle now moving on up).

within past two weeks Edema of ankles (mild) and shin (more pronounced).

No new meds, no new nothing since all this began...

Are you taking any medications at this time?    Looks vascular in nature to me.

Thank you for your response.  I don't think I have any of the diseases listed first because I haven't had any fever and the rash is not raised, doesn't itch or scale over.  It's below the skin like little bits of blood.  It doesn't turn white when pressed & starts to fade within 3 or 4 days.  This makes the 2nd episode approx 2 weeks apart.  I have had pain in lower adominal area on the right side that comes & goes.  My doctor ordered an abdominal ultra sound  last month but it did not show anything.  I will ask him to do a 24 hr urine analysis for 5-HIAA.  If it's a small appendiceal carcinoid tumor, the ultra sound probably didn't show it.

Hi, if it is not secondary to the platelets then other causes should be ruled out. Your lesions seems to be like eryhematous rash. The important causes of rash are Rocky Mountain spotted fever, infectious mononucleosis, scarlet fever, Kawasaki disease and drug eruption. Depending upon the prevalence of above mentioned conditions in your area the commonest can be investigated for with specific treatment.
If there is a sense of warmth and erythema on skin and needs to be differentiated from other conditions of rash. Possibilities needed to be ruled out in your case are Carcinoid syndrome, Mastocytosis, Pheochromocytoma, hyperthyroidism and pancreatic tumor/VIPoma. The tests like 24 hrs urine analysis for 5-HIAA, histamine, prostaglandin and catecholamine and other blood tests. If you are exposed to certain allergens you need to avoid it. I suggest you to consult physician. Take care and regards.
