Accessory extensor pollicis longus tendons are rare tendon anomalies. This report describes the case of a 54-year-old man who presented with pain and difficulty extending his thumb. Upon initial examination, despite a history of trauma, he could extend the interphalangeal joint, but with limited range. During the surgical exploration, an accessory extensor pollicis longus tendon was unexpectedly discovered. This tendon ran parallel to the extensor pollicis longus on the radial side and then attached to the distal phalanx of the thumb. Accessory extensor tendons are more commonly found on the ulnar side than on the radial side of the hand; therefore, this case is notable due to the unusual location of the tendon. After appropriate repair surgery, the patient successfully regained a normal range of motion. While previous classifications of extensor tendon anomalies have focused on the relationship between the extensor indicis proprius and extensor digitorum communis, this case suggests that it is also necessary to consider the relationship with the extensor pollicis brevis tendon. This case highlights the importance of recognizing tendon variations, especially in trauma situations. Detecting such variations preoperatively using imaging can significantly impact the treatment plan and surgical approach.

The growing popularity of cosmetic procedures such as liposuction and fat grafting has been accompanied by a rise in associated side effects. Among these, fat embolism syndrome stands out as a potential complication that sometimes has critical consequences. It is important to recognize that fat embolism affects organs through distinct mechanisms from those involved with other types of embolisms. Early diagnosis is crucial. Unfortunately, no effective treatments have been established for this condition. Therefore, starting with a more detailed categorization of diagnoses, developing new treatment methods for each subtype is essential.

Juvenile xanthogranuloma is a benign tumor made up of non-Langerhans histiocytes that predominantly occurs in infancy and early childhood. Juvenile xanthogranuloma can be differentiated from xanthoma by the distribution of the lesions and the absence of lipid abnormalities. It usually develops on the trunk and upper and lower extremities. Histologically, xanthogranulomas show a mixed cellular dermal infiltration with histiocytes, lymphocytes, eosinophils and Touton-type multinucleated giant cells. Classically, juvenile xanthogranuloma is a disease that largely affects infants and children. We describe a rare case of juvenile xanthogranuloma that suddenly developed in the axillary region of a male adult.

Background: Axillary osmidrosis is a disease characterized by axillary malodor. The conventional treatment method of subdermal excision uses Metzenbaum scissors. Recently, subdermal excision using the Versajet system was introduced. However, it is an expensive surgical tool, and a recent study demonstrated a higher frequency of axillary skin necrosis with the Versajet. We propose a novel, cost-effective, and safe subdermal excision method that utilizes an electrosurgical tip cleaner (ETC). Methods: Our retrospective cohort study included 27 patients who underwent subdermal excision from June 2012 to November 2021. The patients were classified into three groups according to the surgical method: Metzenbaum scissors, Versajet, and ETC. The operation time, hospitalization cost, and postoperative complications were investigated. Results: The number of patients in the Metzenbaum scissors, Versajet, and ETC groups was seven, eleven, and nine, respectively. The mean operation time and hospitalization cost were significantly different among the three groups (P<0.05). The longest mean operation time was observed in the Metzenbaum scissors group (112.9±23.6 minutes), followed by the ETC and Versajet groups (76.4±27.1 and 64.2±24.8 minutes, respectively). The most expensive method was the Versajet ($2,346.1±517.7), followed by the ETC and Metzenbaum scissors ($1,391.8±317.7 and $1,279.6±287.5, respectively). No postoperative complications were observed. Conclusions The ETC is a novel method of subdermal excision, comparable to Metzenbaum scissors or Versajet. Therefore, it is recommended for situations where it is necessary to consider both the time and cost of surgery.

Kienböck disease, a rare disease that can cause chronic pain and motor dysfunction, occurs due to avascular necrosis of the lunate bone, which leads to dislocation of the carpal bone. Among various other etiologies, Kienböck disease can cause closed tendon rupture of the finger. In this report, we introduce a case of total rupture of the second extensor digitorum communis and the extensor indicis proprius tendons caused by undiagnosed Kienböck disease in an elderly female patient.

Iatrogenic electrical burns that occur from the use of a defibrillator, a paddle-type cardiac shock device, have been reported in various forms. Electrical burns are usually conducted directly through the skin and are more damaging than scald burns or contact burns. A transcutaneous cardiac pacing device is a patch-type cardiac shock device that automatically delivers a shock when an abnormal heart rhythm is detected. We introduce a unique case of iatrogenic electrical burns caused by the transcutaneous pacing patch of a cardiac shock device. Electrical energy was converted into a spark due to foreign bodies deposited around the patch, resulting in damage to the peripheral area of the skin.
