Acute exanthem and pancreatic panniculitis in a patient with primary HIV infection and haemophagocytic syndrome.

We report a patient with an acute infection with the human immunodeficiency virus (HIV), who initially presented due to a mononucleosis-like illness that included a rash on the upper trunk and limbs, and oral ulceration. The patient developed a haemophagocytic syndrome with severe systemic involvement. Three weeks after the initial presentation, lesions of a pancreatic panniculitis appeared on both legs.

Widespread angiokeratomas and tuberous sclerosis.

We report a 29-year-old woman who had prominent cutaneous markers of tuberous sclerosis, with subependymal nodules and renal cysts on computerized tomographic scan, who also showed multiple angiokeratomas widely distributed on the buttocks and posterior thighs. Enzymatic studies ruled out Fabry's disease and other lysosomal storage disorders. This is the first reported association of widespread angiokeratomas and tuberous sclerosis.

[Health education in school].

OBJECTIVES: To discover the contents of health education taught at present in the EGB (basic) schools of Castelldefels, the opinions of teachers on health education in schools, and to stimulate reflection among teachers and health-workers on health education at school. DESIGN: A crossover study using a self-administered questionnaire. SETTING: EGB schools in the town of Castelldefels. PARTICIPANTS: All the EGB teachers in Castelldefels (n = 261). MEASUREMENTS AND MAIN RESULTS: 148 teachers (57%) replied to the survey. Health education was considered necessary by 56.8% and essential by 33.1%. They needed technical support and adequate material to carry it through. Integration of health education into the teaching programmes of the school syllabus's different subjects was the best way of carrying it out, in the view of the majority. The advantage of different subjects coincided with those described in the "Health Plan for Catalonia". CONCLUSIONS: Given that we consider teachers to be the professionals best-placed to carry out health education at school, it is useful to confirm their awareness of its importance. As health education is also an objective of the primary care teams, these should be the reference and support point for teachers' demands for technical help.

Sinus histiocytosis confined to the skin. Case report and review of the literature.

Sinus histiocytosis with massive lymphadenopathy is an uncommon disease affecting individuals of either sex and of all ages and ethnic backgrounds. We present a case of sinus histiocytosis confined to the skin in a 65-year-old woman whose diagnosis was coincident with herpes simplex virus infection and polybacterial urinary infection, both asymptomatic. The polymerase chain reaction for herpes simplex virus and human herpesvirus-6 from involved skin was negative. We review previously published cases of sinus histiocytosis limited to the skin.

Erythroderma. A clinicopathological study of 56 cases.

BACKGROUND AND DESIGN: Erythroderma may be the result of many different causes. There are several publications on this subject, most of them from England, the United States, and the Scandinavian countries reporting a different incidence of each etiologic group. Our objective has been to determine the frequency of erythroderma in our environment, its cause, and patient evolution. We reviewed the clinical, laboratory, and biopsy material of 56 patients diagnosed with erythroderma who were treated in our department in the last 8 years (1984 through 1991). Patients were followed up to know the evolution of the erythroderma. RESULTS: The male-female ratio was 4:1. The mean age at diagnosis was 57 years. Dermatoses were the most frequent cause of erythroderma (62.5%), followed by topical or systemic drug reactions (16%), and cutaneous T-cell lymphomas (12.5%). Follow-up information was obtained from 42 patients (66%). Eight patients died (19%), but only in three cases was death directly related to erythroderma (7.14%). The group associated with the best prognosis was that related to drugs. The best clinicohistologic correlation was found in cutaneous T-cell lymphoma-related erythroderma. CONCLUSIONS: Erythroderma of unknown cause and protracted course may be secondary to senile atopic dermatitis, intake of drugs overlooked by the patients, and patients who are in slow progression to cutaneous T-cell lymphoma. Close follow-up of erythrodermas of unknown cause by repeating cutaneous biopsies will in time allow an early diagnosis in patients in the latter group.

Juvenile xanthogranuloma with central nervous system involvement.

An 18-year-old man has been followed in our department since age 10 years when he began to develop numerous yellow, papular lesions on the scalp, face, neck, trunk, and upper extremities. The lesions enlarged slowly to form yellow-brown nodules measuring up to 6 cm. During this period five of the nodules and two small papules were excised. Histopathology was consistent with juvenile xanthogranuloma (JXG). Recently, the patient complained of significant loss of memory, and a computed tomography scan was performed showing several cerebral and cerebellar lesions. The cutaneous lesions in our patient were almost identical to those described elsewhere as being characteristic of progressive nodular histiocytoma. The many clinical and histopathologic similarities between lesions of progressive nodular histiocytoma and JXG suggest that they may represent a continuum rather than two distinct disease processes. Given the fact that there are no histopathologic differences with JXG, as well as the wide range of clinical lesions that JXG may adopt, there is no reason to separate the entities. Although JXG lesions are usually believed to be benign and self-healing, large nodular forms can be associated with visceral lesions. Only four previous cases of cutaneous JXG with central nervous system involvement were found in a review of the literature.

Erythema elevatum diutinum associated with celiac disease: response to a gluten-free diet.

An 11-year-old girl with a history of insulin-dependent diabetes mellitus had erythema elevatum diutinum (EED) associated with a celiac disease related to a possible kidney disease. Dapsone did not improve the skin manifestations. However, the lesions disappeared after a gluten-free diet was begun. To our knowledge, this report describes the first case of EED in a patient with celiac disease.
