Neurofibroma is a rare nerve sheath tumor of neuroectodermal origin, especially the huge and isolated neurofibroma located in the inguinal region. To our knowledge, no such case has previously been reported. We report a case of 34-year-old male patient with a 4-year history of progressive enlargement of the medial root mass in his left thigh with sitting and standing disorders along with pain. The tumor was completely removed by operation, and pathological diagnosis showed neurofibroma. There was no obvious neurologic defect after surgery, and no recurrence tendency was found in the follow-up of 2 years. For a large solitary mass with slow growth and no malignant clinical manifestations for a long time, clinicians cannot rule out the hypothetical diagnosis of neurofibroma, even though its growth site is very rare, such as this case of a huge tumor located in the groin. For neurogenic tumors, early operation should be performed, and the prognosis of patients after tumor resection is excellent.
