CONCLUSION :
AFH is a rare disease that is often misdiagnosed initially. Patients can present with a clinical picture suggestive of other diseases, such as popliteal cyst as in our patient. In our series, AFH occurred in relatively older patient and was found in deep lesions. Although patients with AFH seem to have excellent prognoses, the chances of local recurrence and metastasis might be higher than initially expected. Therefore, Surgeons must be aware of AFH and include it in clinical, radiological, and histopathological differential diagnosis .
