Lipofibromatous hamartoma (LFH) is a rare, benign lesion of the peripheral nerves, which most frequently involves the median nerve and its digital branches (80 %). It is characterized by gradual proliferation of perineural fibroadipose tissue, which also invades epineurium and perineurium. As an outcome of invasion, the nerve fascicles separate from each other yielding a pathognomonic cable-like appearance on magnetic resonance imaging (MRI). Even though the treatment of LFH is debatable, since it causes symptoms due to nerve compression, decompression surgery, along with the reduction of fibroadipose tissue and limited excision following microsurgical dissection are recommended. We present a case of lipofibromatous hamartoma of the digital nerve.
