Rapidly growing juvenile xanthogranuloma in an adult: a case report

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.

Closed extensor tendon rupture caused by Kienböck disease: a case report

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 Spark Burn Injury to the Chest From a Transcutaneous Pacing Patch

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.

A propeller superficial transverse cervical artery perforator flap for defect coverage of the submental area: a case report

Reconstruction of submental defects is a challenge that needs to be approached carefully, since many important anatomical structures are located in this small space. Both aesthetic and functional outcomes should be considered during reconstruction. In this report, we describe a case where a superficial branch of the transverse cervical artery (STCA) perforator propeller flap was applied for coverage of the submental area. An 85-year-old woman presented with a 3-cm ovoid mass on her submental area. We covered the large submental defect with a STCA rotational flap in a 180° propeller pattern. The flap survived well without any complications at 1 year of follow-up. A STCA propeller flap is a useful surgical option in reconstruction for defect coverage of the submental area.

Angiolymphoid hyperplasia with eosinophilia attached to the masseter muscle

Angiolymphoid hyperplasia with eosinophilia (ALHE) is a rare benign vascular tumor. The pathogenesis of ALHE is unknown; however, it may be linked to local trauma. ALHE predominantly occurs in areas of the preauricular region, forehead, and scalp; the masseter area is rarely involved. A 49-year-old man was referred for a mass in the right cheek region that was felt 2 months prior. Physical and imaging examination results suggested the presence of a benign tumor. Thus, surgical excision was performed. Pathologic findings confirmed an unexpected diagnosis of ALHE. This case was interesting, since the mass occurred at an unusual site with a misdiagnosis of an epidermal inclusion cyst.

A giant solitary vellus hair cyst on the nasal root

Eruptive vellus hair cyst is a rare lesion of the vellus hair follicles as a result of developmental abnormality. This cyst is usually found in children, adolescents, and young adults most commonly involving the chest, upper and lower extremities, and abdomen. Herein, we introduce a 22-year-old male patient with a mass of nasal root, growing since childhood. The mass has grown over the years, causing the protruding of the nasal root contours, leading to decline in the patient’s aesthetic and mental quality of life. In response, we performed complete resection of the mass, which pathologically was a vellus hair cyst. The patient is now satisfied with his appearance and there was no local recurrence during follow up.

The Importance of Preoperative Imaging Study on a Solitary Neurofibroma Originated from the Digital Nerve

This case is about a rare type of a solitary neurofibroma that originated from the digital nerve between the proximal phalanx of a finger and the web space, which was first misdiagnosed as giant cell tumor, ganglionic cyst, or fibroma originating from the tendon before radiologic studies were done. The preoperative magnetic resonance imaging (MRI) showed a non-enhanced well-circumscribed mass and the digital nerve was deviated to the volar-medial side due to the mass effect. Since neurofibroma is difficult to differentiate from others by physical examination, crucial information such as the connection between the mass and the nerve or the deviation of the digital nerve can be obtained by MRI findings. And it is important to plan the surgery safely from this information.

Physical Therapy-Induced Secondary Bony Mallet Finger Deformity

After operation for fracture in the phalangeal bones, rehabilitation is initiated in order to minimize joint stiffness if in the case, complete bony union is confirmed by hand surgeons. The described case demonstrates that bony mallet deformity can occur during physical therapy following by surgical pinning of a proximal phalangeal fracture. This mallet finger deformity occurred due to vigorous rehabilitation for correction of postoperative joint stiffness. So, when hand surgeons treat patients with proximal phalangeal fracture, it is important to minimize joint space involvement and close follow-ups accompanying imaging studies during rehabilitation period.
