Rapidly progressive polyostotic eosinophilic granuloma involving spine: a case report

Abstract

17 yrs. old boy presented with low back pain and progressive deformity with no history of trauma or tuberculosis. Clinically there was tender knuckle formation at L2 level. X-rays showed vertebra plana (concentric collapse) at L2 level along with skull involvement. While being investigated patient developed partial collapse at L3 level and pelvis involvement within a week. On biopsy from L3 vertebra the lesion was found to be eosinophilic granuloma. This is a case report of a rare instance in which acute progression of eosinophilic granuloma occurred involving multiple skeletal sites in an adult.
