Pregnancy and red dots on the skin: petechia or ruby ​​angioma?

The hormonal upheavals of pregnancy favor the appearance of generally benign cutaneous disorders such as petechiae or ruby ​​angiomas. Discover the essentials to know about these small red spots and their possible support.

How to distinguish petechiae from ruby ​​angiomas?

  • A petechia and a ruby ​​angioma (or ruby ​​spot) have several points in common: they are small red or purplish spots, causing neither pain nor itching. In addition, if you press it with your thumb, these spots do not fade. In the end, it is especially their size and duration that distinguish petechiae ruby ​​angiomas.
  • Usually, petechiae are smaller than ruby ​​angiomas: they measure 2-3 mm while ruby ​​angiomas can measure between 2 and 9 mm. In addition, petechia rarely last more than a few days. They usually go away spontaneously, although they sometimes leave very small brownish marks. Ruby angiomas, on the other hand, may persist for several months or more ... It may also be noted that petechiae appear preferably on the legs, but they can also touch another part of the body. Ruby angiomas, on the other hand, develop mainly on the trunk, thighs and backs of the hands.

Petechia or ruby ​​angioma during pregnancy: should you consult?

However, more rarely, petechiae can also be linked to a disease: check if the spots last more than a few days and / or if they multiply and you have a fever.
  • As for the ruby ​​angiomas, they are linked to the dilation of the blood vessels under the skin, again under the action of progesterone. This phenomenon is totally benign, although a little embarrassing on the aesthetic level ...

When ruby ​​angiomas persist ...

  • While petechiae disappear quickly, ruby ​​angiomas can persist more or less long after delivery, the time that blood vessels regain their usual "caliber" ...
  • More rarely, it may happen that ruby ​​angiomas persist durably. They do not pose a health hazard, but if they bother you, you may want to consider a treatment to destroy the small, recalcitrant blood vessels. Today, two main techniques are used: electrocoagulation and laser. Do not hesitate to consult a dermatologist to find the best solution for you.
