We describe two patients who developed multiple itching nodules following immunization with vaccines adsorbed on aluminium hydroxide. Both patients had been treated with vaccines for extrinsic asthma and rhinitis for 4 and 10 years respectively. The lesions were persistent and lasted for several years. Histopathological findings were those of a foreign body reaction. Aluminium was most probably involved in the pathogenesis of these lesions because its presence could be demonstrated in macrophages using energy-dispersive X-ray microanalysis. Although some symptomatic relief was achieved with topical corticosteroids and oral antihistamines, treatment was unsuccessful.
