A case of recurrent nodular fasciitis

Nodular fasciitis is a benign, reactive, myofibroblastic, proliferative process of unknown etiology. It presents as a solitary, painless, rapidly-growing nodule over several weeks' duration. The condition is self-limiting, and proper diagnosis is essential to avoid unnecessary aggressive treatment. Diagnosis is often a challenge because nodular fasciitis may be confused with a malignant tumor due to its aggressive clinical behavior and histological features. It is most commonly located on the extremities and then the trunk. Such lesions also usually occur in middle age and are rarely diagnosed in childhood. We report a case of recurrent nodular fasciitis that arose from subcutaneous tissue on the back of a pediatric patient.
