Safety and efficacy of hairy scalp donors in thick split-thickness skin grafting: Healing and complications at donor sites.

Background: We aimed to investigate how the thickness of removed skin grafts affects the healing time at the donor site, with a focus on the depth of the donor wound and the normal thickness of the scalp.

Methods: We examined the outcomes of the donor sites of thick split-thickness skin grafts using hairy scalp skin in 102 Korean patients. We measured the thickness of the scalp donor skin using preoperative ultrasonography, histometric thickness of normal scalp skin in 61 patients, and histometric thickness of the thickest part of the grafted skin after surgery.

Development of AI-Based Diagnostic Algorithm for Nasal Bone Fracture Using Deep Learning.

Facial bone fractures are relatively common, with the nasal bone the most frequently fractured facial bone. Computed tomography is the gold standard for diagnosing such fractures. Most nasal bone fractures can be treated using a closed reduction.

Salvage percutaneous transluminal angioplasty of the superficial femoral artery in the diabetic foot with deteriorating limb ischemia.

Introduction: PAD frequently co-occurs with diabetes, often leading to chronic nonhealing wounds. Foot gangrene and amputation are common outcomes of untreated CLI.

Case Report: A 67-year-old male with diabetes and deteriorating limb ischemia following surgical stress underwent successful surgical repair after emergency PTA of the SFA for extensive heel necrosis.

Early-Stage Pilomatricoma with Cystic Features: A Case Report and Literature Review.

A conventional pilomatricoma presents as an asymptomatic, firm, subcutaneous nodule, commonly in the head, neck, and extremities of the paediatric population. However, its variants show diverse clinical features, which often pose a diagnostic challenge to clinicians. We recently treated an unusual case of pilomatricoma with cystic features in the upper chest of a 9-year-old girl, which manifested as a single solid tumour floating in a serous-filled sac formed by thick fibrous tissue.

Masson Tumor of the Heel Fat Pad.

Intravascular papillary endothelial hyperplasia (Masson tumor) is an uncommon benign vascular lesion characterized by a reactive proliferation of endothelial cells. This lesion commonly occurs in the head, neck, and upper extremities. Although it can be found anywhere in the body, the lesion has never affected the heel fat pad.

Double Primary Malignancies Involving Cutaneous Carcinoma.

Multiple primary malignancies (MPMs) refer to the presence of 2 or more histologically distinct malignant tumors in the same individual. The prevalence of MPMs has increased owing to earlier detection of tumors by screening tests and improved treatment modalities for primary tumors. Although any combination of malignant tumors is possible, reports of MPMs involving cutaneous carcinoma are uncommon in the literature.

Ossifying pilomatricoma and a novel hypothesis for its pathogenesis: A case report and comprehensive literature review.

Rationale: Pilomatricoma is a benign skin appendageal tumor derived from hair follicle matrix cells that commonly affects the head, neck, and upper extremities of the pediatric population. Since the original tumor description, diverse variants have been reported in the literature. Pilomatricoma with florid osseous metaplasia is described as an ossifying pilomatricoma and is recognized as a distinct variant of this benign tumor.

Salvaging a Totally Avulsed Nail Bed Using Free Grafting and Postoperative Ice Cooling: A Case Report.

Most nail bed injuries occur along with other fingertip injuries; however, isolated total avulsion injuries of the nail bed are uncommon. To obtain optimal results, reconstructive methods should be selected judiciously depending on the type of injury, the patient's needs for their economic status and postoperative aesthetics, and postoperative morbidities. Replantation with an avulsed nail bed, if feasible, can be a reasonable treatment option to avoid the morbidities of other donor sites.

Intravascular papillary endothelial hyperplasia of the finger: a case of Masson's tumor.

Intravascular papillary endothelial hyperplasia is an uncommon benign vascular lesion characterized by a reactive proliferation of endothelial cells. The lesion of the finger often presents diagnostic challenges to surgeons because of its rarity. We report a case of intravascular papillary endothelial hyperplasia to facilitate the recognition of this uncommon lesion.

An unusual presentation of acquired periungual fibrokeratoma: A mixed form of dome-shaped and branching type.

Acquired periungual fibrokeratoma is an uncommon benign fibrous tumour occurring in the periungual area, predominantly the proximal nail fold. We describe a case of acquired periungual fibrokeratoma with an unusual presentation of mixed features including dome-shaped and branching type in order to facilitate the recognition of this variant.

Pseudocystic pilomatricoma: A new variant and review of the literature.

A classic pilomatricoma, which usually presents with an asymptomatic, solitary, firm, subcutaneous nodule in the head, neck, or extremities of the paediatric population, is easily diagnosed based on its characteristic clinical and histopathological features. However, its variants often pose particular diagnostic challenges to clinicians due to their rarity and diverse clinicopathological features. We present a new pseudocystic variant, manifesting as solid lesions floating in a fluid-filled sac.

Giant Mixed Tumor of the Skin Affecting the Hemiface.

Mixed tumor of the skin (MTS) is a rare skin adnexal neoplasm occurring in sweat glands. It is usually benign, measures 0.5 to 3 cm, and presents as a slowly growing, painless, firm nodule commonly in the head and neck regions.

Chemical Burns Following Massage With Chopped Pulsatilla koreana.

Herbal massage is commonly used for cosmetic and antirheumatic purposes in the Republic of Korea. Cutaneous burns can complicate herbal massages, but this is a very rare occurrence. Pulsatilla koreana, the Korean pasque flower, is a species of the genus Pulsatilla from the Ranunculaceae family.

An Alternative to the Wire Scalpel for Nasolabial Fold Subcision: A Preliminary Study Using a Tuohy Epidural Needle and Vicryl Sutures.

Background: Subcision techniques involving wire scalpels are used to correct prominent nasolabial folds, depressed scars, and wrinkles. However, these instruments are not universally available.

Methods: We devised a substitute device, consisting of a Tuohy epidural needle and Vicryl sutures, which are easily accessible and inexpensive.

Nonoperative Management of Extravasation Injuries Associated With Neonatal Parenteral Nutrition Using Multiple Punctures and a Hydrocolloid Dressing.

Introduction: Neonatal extravasation injuries are often associated with peripheral parenteral nutrition. Several treatment modalities have been developed and used for managing these injuries with variable results. However, there is a lack of consensus regarding the management of neonatal extravasation injuries.

Toe resurfacing with a thin thoracodorsal artery perforator flap.

Background: In toe reconstruction, amputation procedures are much more common than salvage procedures. However, toe resurfacing, rather than amputation, provides superior functional and aesthetic results. In this study, we report the clinical outcomes of toe resurfacing using a thin thoracodorsal artery perforator flap.

A Chronic, Nonhealing Wound of the Finger Caused by Polypropylene Suture Material.

Chronic wounds usually result from poor peripheral circulation, neuropathy, pressure, radiation, or infection. Such common types of chronic wounds are easily diagnosed and managed with traditional wound care techniques. In contrast, chronic nonhealing wounds caused by cancerous skin lesions, mycobacterial infections, and foreign-body reactions that are refractory to traditional wound therapy present a particular diagnostic challenge, resulting in erroneous or delayed diagnosis.

Subcision using a spinal needle cannula and a thread for prominent nasolabial fold correction.

Deepening of the nasolabial crease is an esthetically unpleasing aging phenomenon occurring in the midface. Various treatment modalities have been introduced to improve the appearance of prominent nasolabial folds, all of which have pros and cons. Currently, a minimally invasive technique using synthetic dermal fillers is most commonly used.
