Giant lipofibromatous hamartoma of median nerve in a child

Lipofibromatous hamartoma (LFH) is a rare fibrofatty tumor of adipocytes within peripheral nerves, affecting mainly children. It typically presents as a palpable mass surrounding the nerves of the upper limbs, causing pain and neurological deficits in the affected nerve distribution. We report the case of a child with a 2-years presentation of a mass in the right wrist associated with pain and paresthesia, who underwent investigation with magnetic resonance imaging (MRI). It showed thickening of the median nerve with spaghetti-like appearance associated with lipomatous tissue in a coaxial cable-like pattern, both features characteristic of LFH. This case illustrates the importance of MRI in the differential diagnosis of limb masses in the pediatric population.

Lipofibromatous hamartoma of the digital branches of the median nerve presenting as carpal tunnel syndrome: A rare case report with review of the literature.

Lipofibromatous hamartoma (LFH) is a rare, benign fibrofatty tumor composed of a proliferation of mature adipocytes within peripheral nerves, which form a palpable neurogenic mass. It affects the median nerve in 66–80% of cases, causing pain and sensory and motor deficits in the affected nerve distribution. Patients typically present with gradually enlarging nontender lesions in the distribution of the affected nerve. The lesion is also seen to be associated with macrodactyly. The pathophysiology of LFH is unknown. Treatment of LFH is based on symptoms of the condition. Histopathology is characteristic. We present a case of young male diagnosed as lipofibromatous hamartoma of the median nerve involving the right index finger. The case is presented due to its rarity.

The Change of Preoperative and Postoperaive Magnetic Resonance Imaging Findings in Lipofibromatous Hamartoma of the Median Nerve

Lipofibromatous hamartoma is a very uncommon, benign tumor that involves diffuse infiltration of peripheral nerves by normal-appearing fibrous and adipose tissues. We repost a rare case of secondary carpal tunnel syndrome due to a lipofibromatous hamartoma of the median nerve with preoperative and postoperative magnetic resonance images.

Recurrent Lipofibromatous Hamartoma of the Median Nerve / 대한정형외과학회잡지

Lipofibromatous hamartoma is a rare tumor of the peripheral nerves which is characterised by an excessive infiltration of the epineurium and perineurium by fibroadipose tissue and very few cases have been described and reported in the literature. Surgical treatments of lipofibromatous hamartoma include partial excision, debulking operation, nerve decompression and so on. We report a case of recurrent lipofibromatous hamartoma of the median nerve that partial excision was done previously but causing secondary carpal tunnel syndrome and a review of the literature regarding the etiology, pathogenesis and surgical management of lipofibromatous hamartoma.

Symmetric Lipofibromatous Hamartoma Affecting Digital Nerves

Lipofibromatous hamartoma of the nerve is a benign tumor, which affects the major nerves and their branches in the human body. It is often found in the median nerve of the hand and is commonly associated with macrodactyly, but it is rarely found in the digital nerves at the peripheral level. This tumor is often found in young adults and may go through a self- limiting course. However, operation is indicated when the tumor size is large or when the associated nerve compressive symptoms are present. We have experienced a rare case of lipofibromatous hamartoma that symmetrically involved the volar digital nerves of both index fingers on the ulnar side. With the aid of a microscope, we dissected and removed the tumor as much as possible without sacrificing the nerve. No sensory change occurred in both fingers and no sign of recurrence was observed upon follow-up.

Lipofibromatous Hamartoma of Median Nerve with Carpal Tunnel Syndrome: A Case Report

Lipofibromatous hamartoma of median nerve is an extremely rare tumor that involves the palmar aspect of the hand, wrist and distal forearm. Other terms to describe this condition include macrodystopia lipomatosa of median nerve and median nerve territory-oriented macrodactyly. Lipofibromatous hamartoma is the most common condition associated with macrodactyly in the hand Also it most commonly involves the median nerve and is one of the causes of carpal tunnel syndrome. We present a review of our experience with this unusual neoplasm and give a detailed follow-up on patient treated by surgical exploration with carpal tunnel release.
