AB Fibrolipoma is characterized by the presence of prominent bundles of mature fibrous tissue traversing the fatty lobules. We present a case of a pathologically-proven fibrolipoma arising in the right ring finger of a 66-year-old female. Physical examination showed a 2-cm, soft, mobile, nontender mass. Neurovascular examinations including Tinel sign were normal. Plain radiographs revealed a well-defined radiolucent area with no calcification. Magnetic resonance imaging showed a lipomatous tumor with an unusual biphasic pattern. The patient underwent an excisional biopsy. Histologically, the tumor consisted of mature adipocytes with sclerotic fibrous elements as well as myxoid changes. The patient has had no evidence of local recurrence within seven months of follow-up. To the best of our knowledge, this is the first report of fibrolipoma without nerve involvement in the finger. Although nonspecific, clinicians should know the various imaging features of fibrolipoma to avoid an unnecessarily extensive surgery.
