What to look out for if you are pregnant and get a rash
The immune system undergoes a huge number of changes during pregnancy to accommodate a new being living inside the womb.  The 5 commonest dermatoses seen during pregnancy are:

Eczema: This is common both during pregnancy and after delivery.

Darkening/Melasma: The pregnancy hormones have direct effects on melanocytes (the cells that regulate skin colour) and produce darkening.  This can also occur on the face as a result of sun exposure and female contraceptive tablets.

Polymorphic eruption of pregnancy: Itchy bumps that appear on the abdomen, often in sites of stretch-marks, and extend to the arms and thighs.  This condition (formerly know as pruritic urticated plaques and papules of pregnancy – PUPPP) occurs during the third trimester of pregnancy and may recur on subsequent pregnancies.

Multiple haemangiomas: These clumps of blood vessels (or telangiectasia) can pop up towards the end of pregnancy as the blood volume is massively increased and the small vessels on the skin stretch.  They usually fade away in the weeks after delivery but can be easily removed if need be.

Pemphigoid gestationis: A rare blistering condition caused by autoantibodies that appear in pregnancy.  Both mum and baby can be affected, but the condition is easily treated.
