SUBCUTANEOUS GRANULOMA-ANNULARE - RECOGNITION AND TREATMENT

Subcutaneous granuloma annulare (SGA) is a benign inflammatory disorde r that occurs in children. The profiles of 12 children with SGA who we re diagnosed and treated at our institution were reviewed. The patient s presented with a rapidly growing, painless soft-tissue mass of the e xtremities or scalp. Parental concerns of malignancy and lack of recog nition of this condition by the physician led to excessive diagnostic testing and, on occasion, inappropriate therapy. The mean age at prese ntation was 3.9 years, and the mean follow-up after biopsy study was 3 .4 years. The lesions were most commonly located about the elbow, knee , and scalp. While complete blood count, erythrocyte sedimentation rat e, and plain radiographs were helpful in ruling out other conditions, no ancillary test was specific for this disorder. In all cases, defini tive diagnosis required a biopsy sample. Excisional biopsy was diagnos tic but not therapeutic, because 75% of the children had one or more r ecurrences of this condition at either local or distant sites. Two of the subsequent lesions resolved spontaneously, and no child within the study group has progressed to any recognized systemic illness or conn ective-tissue disorder.
