1/12. Immune-mediated pathology following hepatitis B vaccination. Two cases of polyarteritis nodosa and one case of pityriasis rosea-like drug eruption.

    The association of hepatitis b virus infection and vasculitis or other immune-mediated manifestations is well documented. Reports on such manifestations in relation to hepatitis B vaccination are scarce, however. We report 2 patients who developed polyarteritis nodosa following vaccination against hepatitis B. In one patient this resulted in an ischemic and necrotic digital ulcus, necessitating surgical amputation. The other patient presented with typical cutaneous polyarteritis nodosa which responded well to corticosteroid treatment. A third patient developed a severe pityrias rosea-like eruption. He was treated with topical steroids with healing of the lesions, leaving only post-inflammatory hyperpigmentation. The literature on these associations is reviewed.

2/12. Localized pityriasis rosea.

    pityriasis rosea is a relatively common skin disorder. In its typical form it is easily recognizable; however, atypical forms can pose diagnostic problems. We report a 44-year-old woman with an acute onset of a localized eruption on her left breast. The morphology of the rash and the time course were typical of pityriasis rosea. Localized pityriasis rosea is an unusual variant, which has been described previously.

3/12. pityriasis rosea-like eruption due to pneumococcal vaccine in a child with nephrotic syndrome.

    A pityriasis rosea-like eruption can occur as a consequence of treatments with gold compounds and captopril. It has rarely been reported to have an association with vaccinations such as smallpox, BCG, hepatitis B, and diphtheria toxoid. It has not previously been documented to develop after pneumococcal vaccination. We report a case of pityriasis rosea-like eruption that developed following pneumococcal vaccination in a child with nephrotic syndrome.

4/12. Atypical pityriasis rosea and Hodgkin's disease.

    pityriasis rosea (PR)-like eruptions have been associated with several neoplasms and drugs. These eruptions may be atypical. To date, the association of Hodgkin's disease with PR-like eruptions has rarely been reported. We report a 37-year-old patient with clinical lesions of PR-like, systemic symptoms and lymphadenopathies, who was subsequently diagnosed with Hodgkin's disease.

5/12. 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.

6/12. 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.

7/12. 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.

8/12. 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.

9/12. pityriasis rosea-like eruption due to bismuth.

    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.

10/12. pityriasis rosea-like eruption after bone marrow transplantation.

    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.
