| pityriasis rosea (PR) is a relatively common disease although its aetiology has not yet been identified. It occurs worldwide and there is no racial susceptibility factor. It usually affects teenagers and young adults between 10 and 35 years of age. Typical PR is much easier to diagnose than the rare atypical forms. We report a rare case of vesicular PR in a black woman who had vesicular lesions limited to her palms and soles in addition to regular typical lesions. We devised an efficient oral erythromycin treatment for this patient. ( info) |
12/19. 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.

13/19. pityriasis rosea with palmoplantar plaque lesions. pityriasis rosea is a skin disease characterized by sharply defined pruritic red patches covered by fine scales. It affects mostly adolescent and young adults. Typical lesions usually affect the trunk in a Christmas-tree pattern. The eruption usually resolves after 6 weeks but symptomatic treatment may be needed. Two patients are reported with classic presentation of pityriasis rosea except for the unusual associated palmoplantar lesions; both patients had negative RPR (with dilutions) and MHA-TP. They responded to 2-week courses of either oral erythromycin or clarithromycin with complete resolution. ( info) |
14/19. pityriasis rosea-like eruption during treatment with imatinib mesylate: description of 3 cases. Imatinib mesylate (IM) represents the first-line treatment for chronic myeloid leukemia (CML). We hereby relate 3 cases of an IM-induced pityriasis rosea (PR)-like cutaneous eruption. patients developed an erythematous, slightly pruritic, macular skin eruption, with many lesions having a peripheral collarette of desquamation, confined to the trunk, limbs, and arms with a vaguely dermatomal diffusion. The histologic findings suggested a reactive process to the drug. Full dermatological recovery was obtained after IM discontinuation, but lesions reappeared upon restoring therapy, suggesting the drug-related nature of the rash. To our knowledge this is the first reported PR-like cutaneous eruption to IM. ( info) |
15/19. pityriasis rosea-like eruptions due to mustard oil application. A young man employed in a construction company, presented with cutaneous lesions clinically simulating pityriasis rosea. Satisfactory and complete response to corticosteroids and antihistamines was followed by recurrence. Multiple recurrences within a short span of time arose a suspicion of alternative diagnosis. Site visit helped us to rule out occupational contact dermatitis. Further history taking revealed that he was recently using mustard oil for body massage. Subsequent patch testing confirmed contact hypersensitivity to mustard oil. Avoidance of the contact with mustard oil arrested appearance of further skin lesions. We stress the importance of taking a good history in clinical practice in disclosing a possible contactant. ( info) |
| We report a case of bismuth-induced pityriasis rosea-like drug eruption. Although historical accounts of bismuth hypersensitivity exist, contemporary reports are lacking. Given the frequency of bismuth administration, a modern review of this phenomenon would seem prudent. ( info) |
| bone marrow transplantation is associated with numerous cutaneous complications that may be related to the underlying (preexisting) disease, to pretransplant conditioning, to immunosuppression, to concomitant medication, or to graft-versus-host reaction. We describe four bone marrow transplant recipients with the clinical and histologic features of pityriasis rosea, a hitherto unreported association. ( info) |
18/19. A pityriasis rosea-like eruption secondary to bacillus Calmette-Guerin therapy for bladder cancer. The use of bacillus Calmette-Guerin (BCG) for the treatment of bladder cancer has been followed by reports documenting adverse reactions. Eruptions of the skin have been included (although not well described) in the list of side effects. We report a pityriasis rosea-like rash secondary to BCG therapy for bladder cancer. Although the treatment was interrupted because of this reaction, the medication was restarted later with only a mild transient recurrence of the eruption. ( info) |
19/19. Cutaneous adverse effects associated with terbinafine therapy: 10 case reports and a review of the literature. Terbinafine is an allylamine antifungal agent widely used to treat dermatophyte onychomycosis and dermatomycoses. We report 10 severe cutaneous adverse reactions associated with terbinafine therapy which required discontinuation of the antifungal agent: erythema multiforme (five patients), erythroderma (one), severe urticaria (one), pityriasis rosea (one) and worsening of pre-existing psoriasis (two patients). The spectrum of cutaneous adverse effects associated with terbinafine therapy is reviewed. patients should be counselled about discontinuing terbinafine at the onset of a cutaneous eruption and about seeking medical advice about further management.
