Pityriasis rosea is also known as Gibert’s disease and is a body rash starting as a “herald patch” lesion and followed by the symptoms of upper respiratory tract infection and a rash all over the body, which lasts for about 6 weeks. Larger patches are called mother patches, while smaller ones – daughter patches. As a rule, a “herald patch” lesion appears on the abdomen, bit in rare cases it can occur in a hidden place. Pityriasis rosea is non-contagious and non-dangerous, but it causes a strong psychological and physical discomfort.

Pityriasis rosea causes are not certain and doctors can only guess what provokes it. Viral infections and HHV-7 are called to be if not the possible causes then the conditions, which stimulate the development of Gibert’s disease. Stress, weak immune system and diabetes are other most common pityriasis rosea stimulators.

Herald Patch

Pityriasis rosea starts a small patch on the skin, called “herald patch”. Upper respiratory tract infection precedes it in approximately 70% of cases. In a week or 2 the initial patch is followed by an oval-shaped rash on the torso or the extremities. The patches can also appear on cheeks or at the hairline. 1 in 4 people suffers from itching. The list of other symptoms includes: headache, nausea, fever and fatigue.

The diagnosis is usually made clinically. The tests to rule out other similar diseases are made and they are followed by a biopsy of the lesions.
