Pitiriasi Rosea (Pityriasis rosea) sulla schiena ― Macule e chiazze asintomatiche, a differenza delle eruzioni da farmaci che solitamente pruriscono.
Se prude molto, potresti sospettare una malattia allergica come nummular eczema.

Pityriasis rosea è una condizione temporanea della pelle caratterizzata da chiazze e squame sollevate. Di solito si inizia con una singola patch, nota come herald patch , seguita da altre patch che compaiono nelle due settimane successive. Tuttavia, non tutti i soggetti affetti da pitiriasi rosea avranno questo cerotto iniziale. Queste macchie spesso formano un disegno distintivo che ricorda un albero di Natale sul tronco e sugli arti superiori.
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 è un'eruzione cutanea comune che di solito inizia con una singola chiazza sul tronco e si diffonde fino a coprire il tronco e gli arti. La diagnosi si basa sull'esame clinico. La toppa iniziale appare rossa con il bordo rialzato e il centro infossato. L'eruzione cutanea emerge in genere circa due settimane dopo. I pazienti possono avvertire affaticamento, nausea, mal di testa, dolori articolari, linfonodi ingrossati, febbre e mal di gola insieme all'eruzione cutanea. Condizioni simili includono la sifilide, la dermatite seborroica, l'eczema e altri. Il trattamento mira ad alleviare i sintomi con corticosteroidi o antistaminici. L'aciclovir può aiutare in alcuni casi. I casi gravi possono trarre beneficio dalla fototerapia UV. La malattia durante la gravidanza a volte è stata collegata all'aborto spontaneo.
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 è una condizione della pelle comune che colpisce tipicamente adolescenti e giovani adulti (di età compresa tra 10 e 35 anni) , leggermente più femminile. Esordisce all'improvviso, di solito con una singola macchia nota come herald patch sul tronco, seguita da un'eruzione di piccole macchie ovali rosate circondate da un anello grigiastro. Queste macchie spesso formano un disegno simile a un Christmas tree sul tronco. L'eruzione cutanea di solito dura circa 6-8 settimane. Pityriasis rosea colpisce circa lo 0,68% delle persone che si rivolgono a un dermatologo, ma questo valore può variare dallo 0,39% al 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%.

Sebbene la causa non sia del tutto chiara, si ritiene che sia correlata all'herpesvirus umano 6 o all'herpesvirus umano 7. Non sembra essere contagioso. Alcuni farmaci possono provocare un'eruzione cutanea simile. La diagnosi si basa sui sintomi e la biopsia solitamente non è necessaria.
Essendo una malattia comune, circa l’1,3% delle persone ne viene colpito prima o poi. Si verifica più spesso nei soggetti di età compresa tra 10 e 35 anni.
○ Diagnosi e trattamento
Se persiste per più di 1 mese, potrebbe essere necessaria un'indagine dettagliata per differenziarla da altre malattie (parapsoriasi, sifilide).
