## TL;DR

A rare case of a lipoma in the hypothenar region causing ulnar nerve symptoms is reported, with successful surgical removal and recovery.

## Contribution

The paper presents a rare clinical case and emphasizes the importance of early diagnosis and nerve-sparing surgery for hypothenar lipomas.

## Key findings

- A lipoma in the hypothenar region caused ulnar neuropathy symptoms in a 43-year-old male.
- Surgical excision with nerve preservation led to complete sensory recovery and no recurrence.
- Early diagnosis and nerve-sparing techniques are crucial for effective treatment.

## Abstract

Lipomas of the hand are rare, particularly in the hypothenar region. We present a case of a 43-year-old male patient with a slow-growing, painless mass in the right hypothenar area causing intermittent tingling and paresthesia in the ulnar nerve distribution. Magnetic resonance imaging (MRI) confirmed a lipomatous lesion. Surgical excision revealed the mass adherent to the superficial branch of the ulnar nerve. Histopathology confirmed a benign lipoma. The patient experienced complete sensory recovery six months postoperatively, with no recurrence. This report discusses the importance of early diagnosis and nerve-sparing excision in hypothenar lipomas.
