Abstract
Lipomas are benign tumors that rarely settle in the hand. They usually present with mass, pain, and nerve compression symptoms. Although isolated median or ulnar nerve compression neuropathy secondary to a lipoma of the hand has been widely reported, simultaneous median and ulnar nerve compression neuropathy are exceedingly rare and there are only three reported cases in the current literature to date. Herein, a case of a 50-year-old woman with a giant palmar lipoma that caused median and ulnar compression neuropathy is presented. The removal of the tumor resulted in the complete recovery of the patient’s symptoms. A deep-seated palmar lipoma should be kept in mind in patients with unilateral compression neuropathy symptoms with a palmar mass.
Highlights
Lipomas are benign soft tissue tumors derived from mature adipose tissue
In a retrospective study of the epidemiology of hand tumors, only 20 (4.9%) out of 402 hand tumors were diagnosed as lipomas [1]
A lipoma may masquerade as thenar or hypothenar atrophy, which is an important physical examination finding in nerve compression syndromes
Summary
Lipomas are benign soft tissue tumors derived from mature adipose tissue. Theoretically, these tumors may involve every organ throughout the entire body where fat tissue is present. Several nerve compression neuropathy cases of the hand secondary to lipomas have been described and published. Most of these cases involved either the ulnar nerve or the median nerve [3,4,5]. Simultaneous median and ulnar nerve compression neuropathy due to lipomas is exceedingly rare and there are only three reported cases in the current literature to date (Table 1) [6,7,8].
