[Phenylbutazone-induced sialadenitis fever simulating angioedema].

BACKGROUND: Drug-induced sialadenitis is uncommon and unrecognized. Drugs such as nitrofurantoïn, nifedipine and methimazole have been reported to induce sialadenitis. However, phenylbutazone and oxyphenbutazone are the most frequently implicated agents. We describe a case of phenylbutazone-induced parotitis and submaxillitis with cutaneous and hepatic involvement. CASE REPORT: A 51 year-old woman who had received phenylbutazone for the past 6 days was hospitalized for diagnosis of Quincke's oedema. Clinical examination in fact revealed bilateral parotitis and submaxillitis. The patient had contracted mumps in infancy. Improvement was noticed 8 days after stopping the drug and treatment by glucocorticosteroid. Nevertheless a pruritic eruption with fever appeared. Laboratory data showed leukocytosis with neutrophilia, ESR of 75 mm/hr, hepatic cholestasis and cytolysis. Infectious and autoimmune causes were ruled out. The eruption spontaneously disappeared after 5 days. Laboratory studies 3 weeks later were normal. DISCUSSION: Quincke's edema diagnosis had been established too fast on "allergic past history" and patient interrogation. Complete clinical examination revealed the correct diagnosis of sialadenitis. This observation shows similarities with other publications: unbearable xerostomia appearing before sialadenitis and with a long course, parotitis with sub-maxillitis, 6 days delay after the first administration of phenylbutazone before fever, local evolution without complication, inflammatory biological syndrome with neutrophilia and absence of infectious cause. Pruritic maculo-papulous eruption and biological hepatic abnormalities are however rare. An hypersensibility mechanism is discussed.

[Plaque variant of trichoblastic fibroma].

BACKGROUND: Tricoblastic fibroma is a rare benign skin tumor originating in the hair follicle. There are two clinical presentations: nodular and plaque variants. The plaque variant is almost exclusively located on the face with deep tissue infiltration. CASE REPORT: A 38-year-old man presented with a 2 cm diameter cutaneous plaque located on the right cheek. It had first been noted by the patient 3 years earlier and had enlarged slowly. On examination, the plaque was well defined, yellowish and slightly indurated. The first clinical diagnosis was basal cell carcinoma and the plaque was removed. Histology provided the diagnosis of trichoblastic fibroma. The patient remains well, with no evidence of recurrence, 10 months after excision. DISCUSSION: Trichoblastoma is an inclusive term for all benign cutaneous neoplasms that are mostly composed of follicular germinative cells. According to Altman, the plaque variant of trichoblastic fibroma is a poorly circumscribed neoplasm, particularly at its lateral and deep margins. This author also states that mitotic figures are more numerous in the plaque variant of trichoblastic fibroma and considers this clinical variant as a low-grade follicular malignancy.

Pulmonary embolism and transitory anti-beta2-GPI antibodies in an adult with chicken pox.

Anti-beta2-glycoprotein I antibodies are considered as a specific marker for the antiphospholipid syndrome. In contrast to lupus circulating anticoagulant and anticardiolipin (aCL) antibodies, they are usually not found at significant levels in infections. We report a case of pulmonary embolism in an adult with varicella. Transient significant levels of aCL antibodies and of IgM anti-beta2-GPI antibodies were observed. No other prothrombotic factor, including free protein S antigen deficiency, was found. The direct pathogenic role of these transient antibodies on the thrombotic event may then be suspected. They are probably associated with VZV acute infection and are absent two months after varicella.

[Multiple trichodiscomas associated with colonic polyposis].

BACKGROUND: Trichodiscoma is an uncommon benign tumor of the pilosebaceous system. CASE REPORT: An 83-year-old man had a past history of adenomatous polyps of the colon. The subject's brother had died from cancer of the colon. Over the past 4 years, the patient had developed approximately 30 small asymptomatic papulonodular tumors on the trunk. Skin biopsy demonstrated trichodiscomas. DISCUSSION: Together with fibrofolliculomas and perifollicular fibromas, trichodiscomas are benign tumors of the pilosebaceous system. These different tumors may occur simultaneously as in Birt-Hogg-Dubé syndrome which associates trichodiscoma and familial colonic polyposis. This combination has only been reported in Birt-Hogg-Dubé syndrome or with perifollicular fibromas. CONCLUSION: This case suggests that patients with hamartomas of the pilosebaceous system should undergo explorations in search for digestive tract polyposis.

[Pigmented pemphigoid].

BACKGROUND: Pigmented bullous pemphigoid has many clinical manifestations. We report a pigmented erythematous form with disseminated bullae. CASE REPORT: A 70-year-old woman with a history of breast adenocarcinoma developed an eruption of pigmented macules on the trunk and members of 72 hour duration. At five days, there was an eruption of tight bullae. The diagnosis of bullous pemphigoid was retained because of the association of infraepidermic bullae, linear deposits of C3 along the basal membrane and the presence of the 180 kDa minor bullous pemphigoid antigen on immunoblotting. DISCUSSION: The initial pigmented aspect of this bullous pemphigoid suggested disseminated pigmented bullous erythema, but histology data with immunotransfer corrected the diagnosis. This very atypical presentation led us to look for a particular etiology. There was no argument in favor of a malignancy in this patient in complete remission after treatment of her breast adenocarcinoma. The fact that the patient was phototype IV would probably explain the pigmented nature of the initial lesions.
