Unusual Cases of Pityriasis Rosea
Title: Atypical presentations of pityriasis
rosea: case presentations.
Authors: Chuh A, et al.
Publication: J Eur Acad Dermatol Venereol. 2005
The authors presented 4 unusual cases of pityriasis rosea:
- A 33 year-old man with purpuric lesions (lesions in the skin
that appear as purplish spots or patches) on both sides of his
legs, and with the classical rashes on the trunk of his body.
- A 28-year old woman with intensely itchy and hives-like rashes.
- A 10-year old girl with hundreds of small bumpy lesions about
1 to 3 mm (about 1/24th to 1/6th of an inch).
- A 26-year old pregnant woman with bleeding oral ulcers and
classical pityriasis rosea rashes on the trunk of her body.
The oral ulcers came and went at the same time as the rashes.
The authors proposed a classification based on the shape, size,
distribution, number and location of the rashes, as well as
the severity of the symptoms and the course of the rash eruptions.
The authors believed that it is difficult to make a clear distinction
between typical and atypical pityriasis rosea, and that it is
important not to classify unusual or atypical skin eruptions as
pityriasis, without excluding other skin diseases.
