Paraffin filling has been previously used for muscle atrophy treatment. However, the formation of paraffin granulomas (paraffinomas) can occur over the long term. We encountered a patient with leprosy who had hypothenar muscle atrophy caused by ulnar neuropathy. The patient was treated with paraffin injection at the hypothenar site for cosmetic appearance 60 years ago. Consequently, the paraffin formed a paraffinoma and a recurrent infected skin ulcer. Thus, paraffinoma removal and transfer of ulnar artery perforator adiposal flap (140&nbsp;× 20 mm) were performed. The ulnar artery perforator adiposal flap was used for infection control and filling the dead space after paraffin removal. The skin healed without complications. Ultrasound confirmed residual adipose tissue and blood flow at the last follow-up.</p>
