Allergic periorbital mucopyocele in children

Two patients, an 11-year-old boy and a 13-year-old girl, with firm nontender progressive swelling in the medial canthal region also had histories of asthma and peripheral eosinophilia. Radiologic studies disclosed ethmoidal sinus ectasia and opacification. At surgery, a firm mass that filled the sinus was found in each case. Histologically, these masses consisted of inspissated mucus and a dense infiltrate in eosinophils. Surgical drainage resulted in a cure of one case and improvement in the other. Because of the marked allergic diathesis in both patients and the specific or unique character of the sinus contents, we propose the term allergic periorbital mucopyocele for this disorder.
