          Abstract

          Unusual clinical features are known in pityriasis rosea (PR). We report a case of a child who presented with onset of PR in scalp, clinically mimicking pityriasis amiantacea. Careful clinical observations and follow-up led us to appropriate diagnosis.

          Atypical presentations of pityriasis rosea: case presentations.

          Atypical cases of pityriasis rosea (PR) are fairly common and less readily recognized than typical eruptions. We present four patients for whom we believe atypical PR is the most likely diagnosis. A 33-year-old man had purpuric lesions bilaterally on the legs with classical rash on the trunk. A 28-year-old woman had intensely pruritic and urticarial lesions. A 10-year-old girl had hundreds of small papular lesions 1-3 mm in size. A pregnant woman aged 26 had oral haemorrhagic ulcers with classical PR eruption on her trunk. The oral ulcers erupted and remitted at the same time as the generalized eruption. We reviewed the literature and proposed a classification based on rash morphology, rash size, rash distribution, number of lesions, site of lesions, severity of symptoms and course of the eruption. We believe that it is difficult to make a clear division to define typical and atypical PR, and that it is important not to ascribe any unusual or atypical skin eruption with PR unless other dermatoses have been excluded.

              Pityriasis amiantacea: a clinical and etiopathologic study of 85 patients.

              Studies on pityriasis amiantacea (PA) in the literature are limited and mostly retrospective. We prospectively analyzed the clinical and etiopathologic factors in a large series of PA diagnosed at our department within a defined period (2000-01). All PA patients who attended our department were evaluated clinically and underwent bacteriologic, mycologic, and histopathologic examinations. Forty healthy control persons were similarly subjected to bacteriologic and mycologic investigations of their scalp hairs. A total of 85 PA patients were collected and studied. Pathological diagnosis of scalp psoriasis was confirmed in 35.3% of cases. Eczematous features suggesting a diagnosis of seborrheic and atopic dermatitis were detected in 34.2%. Diagnosis of tinea capitis, diagnosed by potassium hydroxide preparation, fungal culture, and periodic-acid Schiff staining, was detected in 12.9% of the PA patients. Staphylococcus isolates were detected in 96.5% of the PA patients compared with 15% in healthy persons as the control (P > 0.00001). Pityriasis amiantacea represents a particular reaction pattern of the scalp to various inflammatory scalp diseases. The most frequent skin diseases associated with PA are psoriasis and seborrheic dermatitis. It is important to keep the diagnosis of tinea capitis in mind when evaluating PA patients. Staphylococci on the scalp could participate in the pathogenesis of PA.
