We describe a 51-year-old patient with endstage renal disease who developed vancomycin-associated exfoliative dermatitis. After four weeks of vancomycin hydrochloride treatment for staphylococcal pericarditis this patient developed a hypersensitivity reaction characterized by intermittent fevers, lymphadenopathy, peripheral eosinophilia, and exfoliative dermatitis. The reaction persisted for five weeks, probably because of inability to rapidly eliminate vancomycin secondary to underlying renal failure. Maculopapular rashes have been reported in two to six percent of patients who receive this drug, with severe skin reactions rarely reported. In addition to this case report, a review of the literature including 11 Eli Lilly/Food and Drug Administration case reports is presented. Although severe skin reactions to vancomycin rarely occur, they prolong morbidity, particularly in patients with renal failure.
This study was to investigate the epidermiological, etiological, clinical and prognostic aspects of patients with Generalised Exfoliative Dermatitis in Singapore. From 1981 to 1985, all patients with exfoliative dermatitis or erythroderma admitted to our dermatology wards were included into this study. A standard protocol was filled in for each patient, and they were subsequently followed up at our out-patient clinics. There were 79 male and 29 female patients (sex ratio 2.7:1). The average age was 61.5 years. Most of the patients were from low social income groups. Apart from scaling and erythema, peripherial oedema was the most common finding (44%), followed by hair loss (25%) and lymphadenopathy (22%), 15% of patients had haemoglobin level 10G/dl. The main etiological groups were eczema/dermatitis, psoriasis, drug reactions and those with unknown causes. Two patients were suffering from congenital dermatoses. None of our patients was casually related to malignancy. This study suggested that GED was not a fatal disease among our patients, and they often had a good prognosis.

Lymphocytes (T cells and B cells) of a patient with chronic lymphatic leukemia (CLL) were studied immunologically and scanning electron microscopically. The subpopulation percentage of rosette forming cells (T cell) and surface immunoglobulin bearing cells (B cell) were decreased in the peripheral blood. Moreover, tritiated thymidine uptake by lymphocytes in the cell culture stimulated by phytohaemagglutinin (PHA), porkweed mitogen (PWM) and purified protein derivatives (PPDs) was decreased. Scanning electron microscopy (SEM) showed many long villi on the surface of the lymphocytes in the peripheral blood, which implies B cell origin, Observation by electron microscopic immunohistochemistry using the ferritin antibody technique revealed that beta1C/beta1A receptors normally seen on the B cells were also seen on the leukemic lymphocytes. Thus it appears that the leukemic cells in the peripheral blood of this patient are functionally and morphologically abnormal B cells.
