The diagnostic conundrum of Florid Reactive Periostitis: A case report and review of the literature

We report on a case of digital benign fibroblastic proliferative lesion that aggressively recurred after multiple excisions and showed histologic progression from a Fibrosseous Pseudotumor (FOPT) to Florid Reactive Periostitis (FRP). We recommend caution on incisional biopsies that do not excise the lesion fully based on the clinical course, radiographic, and histologic findings. Our case demonstrates the protean nature of this entity and the difficulty in obtaining an accurate diagnosis based on the clinical course and radiographic and histologic findings.
