  https://www.merckmanuals.com/professional/dermatologic-disorders/psoriasis-and-scaling-diseases/pityriasis-rosea

  Pityriasis rosea most commonly occurs between ages 10 and 35. It affects women more often. […] The condition classically begins with a single, primary, 2- to 10-cm herald patch that appears on the trunk or proximal limbs. A general centripetal eruption of 0.5- to 2-cm rose- or fawn-colored oval papules and plaques follows within 7 to 14 days. The lesions have a scaly, slightly raised border (collarette) and resemble ringworm (tinea corporis). […] Most patients itch, occasionally severely. Papules may dominate with little or no scaling in children and pregnant women. […] Initially, most people develop one large scaly patch (herald patch; arrow), and within 1 to 2 weeks, smaller pink patches can occur on the trunk, arms, and legs. […] In pityriasis rosea, the initial herald patch is followed by centripetal eruption of oval papules and plaques with a slightly raised border, typically appearing along skin lines. […] Classically, lesions orient along skin lines, giving pityriasis rosea a Christmas treelike distribution when multiple lesions appear on the back. […] A prodrome of malaise, headache, and sometimes arthralgia precedes the lesions in a minority of patients.

  Pityriasis rosea is a type of skin rash. Classically, it begins with a single red and slightly scaly area known as a „herald patch”. This is then followed, days to weeks later, by an eruption of many smaller scaly spots; pinkish with a red edge in people with light skin and greyish in darker skin. It usually lasts less than three months and goes away without treatment. Sometimes malaise or a fever may occur before the start of the rash or itchiness, but often there are few other symptoms. […] The symptoms of this condition include: Recent upper respiratory tract infections in 869% of patients have been reported by some studies. Occasionally, prodromal flu-like symptoms, including headache, joint pain, mild fever, and fatigue, as well as gastrointestinal symptoms such as nausea, diarrhea, or vomiting, and feeling generally unwell, precede other symptoms. In most cases, a single, 2 to 10 cm (1″ to 4″) oval red „herald” patch appears, classically on the trunk or neck, having an appearance similar to ringworm. After the herald patch appears, usually some days or weeks later, a rash of many small (5-10 mm; 1/4″ to 1/2″) pink or red, flaky, oval or round spots appear. They follow the skin’s cleavage lines, which on the upper chest and back produce a characteristic „christmas-tree” distribution. About one in four people with PR have mild to severe symptomatic itching. The itching is often non-specific, and worsens if scratched. This tends to fade as the rash develops and does not usually last through the entire course of the disease.

  I’m so relieved – I can happily say that my PR is finally clearing up. I’ve had it for about 8 weeks now. About a week before it started to fade I think it 'peaked’ it was intensely itchy and very dry and flaky. A week later the itch had all but gone (except when after a shower) The patches enlarged and flattened and started to fade from the inside of the patch outwards. During this time my skin was very flaky. Within a week the rash had faded down to a tan colour and once the flaking had gone the tan patches were dry looking but flat. The early patches and herald patch have almost completely faded and the patches I got later on are still there but beginning to go. […] I found it was at its worse at about week 5-6 – it got really painfully itchy and very red and dry. Now its really fading at week 9 – the only think it is has left my skin very dry and tight feeling. My skin feels a bit like crepe paper so I’ve bought a load of body scrubs.

  Pityriasis rosea (PR) is considered a relatively common and benign skin rash thought to be caused by a viral infection. It is characterized by a single oval spot, usually on the trunk, followed by a more diffuse outbreak of the rash that occurs 1-2 weeks later. Pityriasis rosea often affects a younger population, typically those 10 to 35 years of age. There is an equal distribution of PR cases between men and women. […] Pityriasis Rosea can have a variety of symptoms with a relatively characteristic rash. Some features of PR include the following signs and symptoms: Herald Patch or Mother Patch: This is the initial presentation of PR. A single, round, salmon-colored patch with peripheral flaking called a “herald patch” or “mother patch” appears first, most typically on the trunk. Christmas Tree pattern rash: About 1-2 weeks after the herald patch appears, many similar, smaller patches erupt, typically over the trunk. They typically appear on the chest first, and then spread across the trunk over skin tension lines or “dermatomes.” This forms a Christmas tree-like pattern across the back. Inverse pattern rash: less than 10% of pityriasis rosea cases exhibit an inverse pattern, meaning the rash appears in skin folds such as the armpits or groin.

  Pityriasis rosea (PR) is considered a relatively common and benign skin rash thought to be caused by a viral infection. It is characterized by a single oval spot, usually on the trunk, followed by a more diffuse outbreak of the rash that occurs 1-2 weeks later. Pityriasis rosea often affects a younger population, typically those 10 to 35 years of age. There is an equal distribution of PR cases between men and women. […] Pityriasis Rosea can have a variety of symptoms with a relatively characteristic rash. Some features of PR include the following signs and symptoms: Herald Patch or Mother Patch: This is the initial presentation of PR. A single, round, salmon-colored patch with peripheral flaking called a “herald patch” or “mother patch” appears first, most typically on the trunk. Christmas Tree pattern rash: About 1-2 weeks after the herald patch appears, many similar, smaller patches erupt, typically over the trunk. They typically appear on the chest first, and then spread across the trunk over skin tension lines or “dermatomes.” This forms a Christmas tree-like pattern across the back. Inverse pattern rash: less than 10% of pityriasis rosea cases exhibit an inverse pattern, meaning the rash appears in skin folds such as the armpits or groin. Burning & Itching: about 25% of patients with pityriasis rosea will have mild to severe symptoms associated with the rash. This most often involves burning, itching, tingling, or sensitivity in the areas of the PR rash.

  Pityriasis rosea is a type of skin rash. Classically, it begins with a single red and slightly scaly area known as a „herald patch”. This is then followed, days to weeks later, by an eruption of many smaller scaly spots; pinkish with a red edge in people with light skin and greyish in darker skin. It usually lasts less than three months and goes away without treatment. Sometimes malaise or a fever may occur before the start of the rash or itchiness, but often there are few other symptoms. […] The symptoms of this condition include: Recent upper respiratory tract infections in 869% of patients have been reported by some studies. Occasionally, prodromal flu-like symptoms, including headache, joint pain, mild fever, and fatigue, as well as gastrointestinal symptoms such as nausea, diarrhea, or vomiting, and feeling generally unwell, precede other symptoms. In most cases, a single, 2 to 10 cm (1″ to 4″) oval red „herald” patch appears, classically on the trunk or neck, having an appearance similar to ringworm. After the herald patch appears, usually some days or weeks later, a rash of many small (5-10 mm; 1/4″ to 1/2″) pink or red, flaky, oval or round spots appear. They follow the skin’s cleavage lines, which on the upper chest and back produce a characteristic „christmas-tree” distribution. About one in four people with PR have mild to severe symptomatic itching. The itching is often non-specific, and worsens if scratched. This tends to fade as the rash develops and does not usually last through the entire course of the disease.
