Decubital Ischemic Fasciitis/Atypical Decubitus Fibroplasia- A Pseudosarcomatous Lesion Commonly Presented as a Sarcoma: Case Report and Brief Review of Literature

Decubital ischemic fasciitis is a rare disease process characterized by pseudosarcomatous fibroblastic proliferation. The disease process is most commonly observed in elderly debilitated or immobilized patients. Its pathophysiology is characterized by degeneration and regeneration of mitotically active fibroblasts. Due to its histologic appearance, proximity to bone, and patient population, decubital ischemic fasciitis is occasionally mistaken for a soft tissue sarcoma. We report a case of this rare condition, diagnosed utilizing magnetic resonance imaging and subsequent core needle biopsy with microscopic evaluation. We also discuss the importance of early and accurate diagnosis in patients suspected of having this condition, as it is vital to rule out the potentially malignant soft tissue sarcoma, while also utilizing effective quaternary prevention and avoiding overtreatment in patients with benign decubital ischemic fasciitis.
