Abstract
Florid reactive periostitis is a benign and rare lesion that is a recurrent diagnostic
problem. Its etiopathogenesis remains unknown. Florid reactive periostitis consists
of a fibrotic, cartilage-producing tumor accompanied by an aggressive inflammatory
periosteal and soft tissue reaction. It typically occurs in adolescents and young
adults, mostly female; it often affects hand and foot bones, and it may occur in long
bones. Its diagnosis remains a major challenge due to the vast possibility of differential
diagnoses. Therefore, careful clinical, radiological, and pathological evaluation
is required to establish a proper diagnosis. We report the case of a patient with
florid reactive periostitis in the proximal phalanx of the right index finger, who
underwent surgical excision with a wide margin, from the second ray to the proximal
third of the second metacarpal bone, and evolved without complications, with satisfactory
range of motion and strength.
