To assess the prevalence of relapses of pityriasis rosea (PR), a retrospective cohort study investigated all PR cases diagnosed in Genoa between 2000 and 2013 and followed them up to today. Of 570 cases, 21 (3.7%) relapsed. Most of them had a single episode, but 4 had two episodes and 2 had three episodes.

Since the initial description of pityriasis rosea as a separate clinical entity by Gibert in 1860, 1 the causal relationship of an infectious agent has received occasional consideration. Attention has been directed toward the possible involvement of fungal or bacterial organisms, 2-4 but to date the role of these micro-organisms in the etiology of the ...

A 17-year-old young man presented with a 2-week history of an asymptomatic widespread eruption affecting the trunk and arms. On physical examination we observed multiple, oval purpuric macules and papules, 1–3 cm in diameter, distributed in a “christmas tree” pattern on the trunk and arms (Figs 1 and 2).

IN ITS classic form, pityriasis rosea is a distinctive dermatosis and is readily identified clinically. A diffuse distribution of skin lesions over the trunk and proximal portions of the extremities is commonly seen. The individual lesions are typically annular and oval in shape, with their long axes parallel to the so-called lines of cleavage of the ...

Pityriasis rosea and Ketotifen
Dermatologica, 2009A 4-year-old female patient who developed a skin eruption similar to pityriasis rosea after treatment with ketotifen (Zaditen) is presented. The relationship between ketotifen and the eruption has been based on circumstantial evidence and confirmed by the positive results of the MIF test and the rat mast cell degranulation test.

ABSTRACT: Some immunologic studies were carried out for 31 patients with pityriasis rosea. Normal levels of serum IgG and IgA but higher levels of IgM were obtained. Serum C3 values were decreased while C4 values were normal. B lymphocytes showed no difference from the controls, whereas T‐cell counts were significantly lower in the patients.

Dermatologica, 2009
Six cases of pityriasis rosea with atypical morphology and distribution of the eruption are reported. The eruption did not show a typical ‘Christmas-tree’ arrangement, confined to the trunk and proximal parts of the extremities. However, the histology of the eruption revealed dyskeratotic cells in the epidermis and extravasated erythrocytes in the ...

ABSTRACT: One hundred thirty‐eight Nigerian patients with pityriasis rosea were studied. Patients with the condition constituting 2.4% of all patients seen in two skin clinics in Northern Nigeria in a period of over three years. The proportional rate of pityriasis rosea parallels figures from other African studies, and is higher than values obtained ...

DISTRIBUTION OF PITYRIASIS ROSEA
Archives of Dermatology, 1950Thirty-six years ago, Fox1stated that "our textbook descriptions of pityriasis rosea need many additions and corrections." According to our present findings concerning the distribution of this eruption, his remark is still valid. Modern dermatologic texts follow the original concept of the distribution of the lesions in pityriasis rosea as given by ...

ABSTRACT: Pityriasis rosea presents in the Sudan with the same picture as it does in other countries of Africa. The seasonal incidence is highest in the cold, dry months. The erythematous or rosea picture seen in whites is never encountered in blacks.
