Pityriasis rosea på ryggen – asymtomatiska fläckar och plåtar, till skillnad från läkemedelsutslag som vanligtvis kliar.
Om det kliar mycket kan du misstänka en allergisk sjukdom som nummulär eksem.

ReferencesPityriasis rosea är ett tillfälligt hudtillstånd som kännetecknas av upphöjda fläckar och fjällning. Det börjar vanligtvis med ett enda utslag, känt som herald patch, varefter fler utslag dyker upp under de kommande veckorna. Men inte alla med pityriasis rosea får detta första utslag. Dessa fläckar bildar ofta ett distinkt mönster som liknar en julgran på trunkus och de övre extremiteterna.
Pityriasis rosea, also known as pityriasis circinata, roseola annulata, and herpes tonsurans maculosus is an acute self-limiting papulosquamous disorder. It is often characterized by an initial herald patch, followed by scaly oval patches within 2 weeks. However, the herald patch is not always present. The scaly oval patches typically distribute in a Christmas-tree pattern on the trunk and proximal extremities. This activity reviews the evaluation and treatment of pityriasis rosea and the importance of the interprofessional team in recognizing and managing patients with this condition.

Pityriasis rosea är ett vanligt utslag som vanligtvis börjar med ett enda plåster på bålen och sprider sig för att täcka bålen och extremiteterna. Diagnosen bygger på klinisk undersökning. Den första fläcken ser röd ut med en upphöjd kant och nedsänkt mitt. Utslagen kommer vanligtvis cirka två veckor senare. Patienter kan uppleva trötthet, illamående, huvudvärk, ledvärk, svullna lymfkörtlar, feber och halsont vid sidan av utslagen. Liknande tillstånd inkluderar syfilis, seborroiskt eksem, eksem och andra. Behandling syftar till att lindra symtom med kortikosteroider eller antihistaminer. Acyclovir kan hjälpa i vissa fall. Allvarliga fall kan dra nytta av UV-ljusbehandling. Sjukdomen under graviditeten har ibland kopplats till missfall.
Pityriasis rosea is a common rash that usually begins with a single patch on the trunk and spreads to cover the trunk and limbs. Diagnosis relies on clinical examination. The initial patch appears red with a raised border and sunken center. The rash typically emerges about two weeks later. Patients may experience fatigue, nausea, headaches, joint pain, swollen lymph nodes, fever, and sore throat alongside the rash. Similar conditions include syphilis, seborrheic dermatitis, eczema, and others. Treatment aims to alleviate symptoms with corticosteroids or antihistamines. Acyclovir may help in some cases. Severe instances may benefit from UV phototherapy. The disease during pregnancy sometimes has been linked to miscarriage.

In most cases, PR does not influence pregnancy or birth outcomes. Analysis of pooled data from our study and from previous studies revealed that the week of pregnancy at onset of PR was inversely associated with an unfavorable outcome (odds ratio [OR] = 0.937; 95 % CI 0.883 to 0.993). In addition, duration of PR (OR = 1.432; 95 % CI 1.129 to 1.827), additional extracutaneous symptoms (OR = 4.112; 95 % CI 1.580 to 10.23), and widespread rash distribution (OR 5.203, 95 % CI 1.702 to 14.89) were directly associated with unfavorable outcome.
Pityriasis rosea är en vanlig hudsjukdom som vanligtvis drabbar tonåringar och unga vuxna (i åldern 10-35) , något mer hos kvinnor. Det börjar plötsligt, vanligtvis med ett enda plåster som kallas herald patch på stammen, följt av ett utslag av små, rosa ovala fläckar omgivna av en gråaktig ring. Dessa fläckar bildar ofta ett mönster som liknar en Christmas tree på stammen. Utslagen varar vanligtvis i cirka 6 till 8 veckor. Pityriasis rosea påverkar cirka 0,68 % av personer som träffar en hudläkare, men detta kan variera från 0,39 % till 4,8 %.
Pityriasis rosea (PR) is a relatively common, self-limited papulo-squamous dermatosis of unknown origin, which mainly appears in adolescents and young adults (10-35 years), slightly more common in females. It has a sudden onset, and in its typical presentation, the eruption is preceeded by a solitary patch termed “herald patch”, mainly located on the trunk. Few days later, a secondary eruption appears, with little pink, oval macules, with a grayish peripheral scaling collarette around them. The secondary lesions adopt a characteristic distribution along the cleavage lines of the trunk, with a configuration of a “Christmas tree”. In most cases, the eruption lasts for 6 to 8 wk. Its incidence has been estimated to be 0.68% of dermatologic patients, varying from 0.39% to 4.8%.

Även om orsaken inte är helt klar, tros den vara relaterad till humant herpesvirus 6 eller humant herpesvirus 7. Det verkar inte vara smittsamt. Vissa läkemedel kan ge liknande utslag. Diagnosen baseras på symtomen och en biopsi är vanligtvis onödig.
Som en vanlig sjukdom drabbas cirka 1,3 % av befolkningen någon gång. Det förekommer oftast hos personer mellan 10 och 35 år.
○ Diagnos och behandling
Om den kvarstår i mer än en månad kan en detaljerad utredning krävas för att skilja den från andra sjukdomar (parapsoriasis, syfilis).
