Pityriasis rosea may be difficult to diagnose until the appearance of these characteristic smaller secondary… 

Pityriasis Rosea-Like Drug Eruptions

Pityriasis rosea is an acute, mild, self-limited papulosquamous skin disease of uncertain etiology. The disease is characterized by the initial presence of a salmon-pink oval patch or plaque deemed

Clinical variants of pityriasis rosea

Atypical presentations of the disease are reviewed, including diverse forms of location and morphology of the lesions, the course of the eruption, and its differential diagnoses.

Unique clinical presentations of pityriasis rosea: aphthous ulcers, vesicles and inverse distribution of lesions.

Three cases of PR are illustrated including those that presented with aphthousulcers, vesicles, and an inverse pattern.

Two Cases with Vesicular Pityriasis Rosea

Two male patients diagnosed as vesicular PR are presented and it is shown that typical PR is much easier to diagnose than the rare atypical forms.

Pityriasis rosea: two cases with uncommon presentations of common disease

Involvement of nail folds and web spaces of hands was seen in one case while vesicles on the erythematous base were seen in other, and atypical features of the disease were reported.

Borrelia infection and pityriasis rosea.

Clinical and experimental findings suggest the pathogenic role of an infectious agent in PR and a link between Borrelia burgdorferi and PR was suggested in the 1990s.

Acral pityriasis rosea: A rare variant of pityriasis rosea

The rare form of acral PR in an adult has been illustrated as the 29year-old Thai female who presented with generalized erythematous papules and plaques with peripheral collarette scales on the trunk and extremities, prominently on the hands and feet.

Vesicular Pityriasis Rosea In An Adult: A Case Report And Review Of The Literature

A case of vesicular PR in an adult woman, raising the question of the differential diagnosis, is reported, with a first single lesion on the abdomen considered as the herald patch followed 5 days after by a squamous and vesicle eruption of the trunk and upper limbs.

Unique clinical presentations of rosea: aphthous ulcers, vesicles and inverse distribution of lesions

Three cases of PR are illustrated including those that presented with aphthous ulcers, vesicles, and an inverse pattern to illustrate the lack of its characteristic manifestations.
