Dupuytren contracture after acute traumatic hand injury in an adolescent: A case report.

Dupuytren's disease is a fibroproliferative disease that affects the palmar hand, causing progressive, permanent, and symptomatic flexion contracture of the digits. It is a disorder of polygenetic and multifactorial origin, usually affecting middle-aged males. Dupuytren's disease developing as a result of hand trauma in younger ages is rarely reported.

Giant lipoma in the index finger of the dominant hand of a swimmer: A case report.

Lipoma is a very common benign tumor that occurs in areas of adipose tissue and is commonly found on the whole body, although its occurrence in the hand and finger is rare. Giant lipoma, defined as over 5 cm long in diameter, is a rare benign tumor of abundant soft tissue in the finger. A 24-year-old male patient presented with a giant lipoma on the volar aspect of the index finger of his right hand.

The Oblique Extended Reverse First Dorsal Metacarpal Artery Perforator Flap for Coverage of the Radial-Volar Defect of the Proximal Interphalangeal Joint in the Index Finger: A Case Report.

The dorsal metacarpal artery perforator flap is a flap that rises from the hand dorsum. Owing to its reliability and versatility, this flap is used as a workhorse for finger defect. However, to cover the radial-volar defect of the proximal interphalangeal joint (PIPJ) of the index finger, a longer flap is required than before.

Neck Pain Caused by Giant Dorsal Lipoma.

Giant lipomas are uncommon in the neck or craniofacial region. A 55-year-old male presented with a large pendulous mass arising from the dorsal aspect of his neck, which he had known about for 20 years. Discomfort during sleeping, frequent headaches, and chronic neck pain were his chief complaints.

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.

Chondrocutaneous posterior auricular artery perforator free flap for single-stage reconstruction of the nasal tip: a case report.

Full-thickness nasal tip reconstruction is a challenging process that requires provision of ample skin and soft tissue, and intricate cartilage structure that maintains its architecture in the long term. In this report, we describe reconstruction of a full-thickness nasal tip and ala defect using a posterior auricular artery perforator based chondrocutaneous free flap. The flap consisted of two lay ers of skin covering conchal cartilage, and was based on a perforating branch of the posterior auricular artery.

Apocrine tubular adenoma on the palm: A case report.

Rationale: Tubular apocrine adenoma (TAA) is a very rare benign neoplasm of the apocrine gland. The typical anatomical locations are mostly hair-bearing areas, where normal apocrine glands are abundant.

Patient Concerns: We report the case of a 40-year-old patient with a tubular apocrine adenoma on a non-hair-bearing area.

Undifferentiated Pleomorphic Sarcoma of a Chronic Burn Scar of the Knee With Lymph Node Metastasis.

Malignant transformation of chronic burn scars are usually toward cutaneous lineages, including squamous cell carcinoma, basal cell carcinoma, and malignant melanoma. Sarcomas are less common. Undifferentiated pleomorphic sarcoma(UPS) is a subtype of soft tissue sarcoma with storiform-pleomorphic cells of uncertain origin, and has sparingly been reported to arise from burn scars.

Propeller posteromedial thigh perforator flaps for coverage of extensive perineal defects.

Background: Reconstruction of perineal defect is challenging. The goal of reconstruction is to maintain normal function with good esthetic outcomes. Coverage of the perineal defect is often difficult with one loco-regional flap when the size of defect is very extensive.

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.

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 Systematic Review of the National Breast Implant Registry for Application in Korea: Can We Predict "Unpredictable" Complications?

Since silicone breast implants were introduced to the market several decades ago, the safety of breast implants has remained controversial. Recently, several studies have explored breast implant-associated anaplastic large-cell lymphoma (BIA-ALCL) and breast implant illness (BII). Several countries have developed national breast implant registries to improve the safety and quality of breast implant surgery.

Necrotizing fasciitis of the masticator space with osteomyelitis of the mandible in an edentulous patient.

Necrotizing fasciitis (NF) is a rapidly progressive necrosis of the subcutaneous tissue and fascia, caused by bacterial infection. Usually presenting in the extremities, trunk, or perineum, it is uncommon in the craniofacial or cervical area. Cervicofacial NF is a potentially fatal infection, which should be managed with early detection and intervention.

Subpectoral Implantation of Cardiovascular Implantable Electronic Device: A Reasonable Alternative for the Conventional Prepectoral Approach.

Background: The prepectoral implantation technique has been the standard procedure for cardiovascular implantable electronic device (CIED). However, it cannot be performed in such patients with thin skin or patients with cosmetic concerns. This study was designed to demonstrate the feasibility and safety of the subpectoral compared to the prepectoral approach.

Acellular dermal matrix (Insuregraf) in the prevention of Frey's syndrome and surgical site depression after parotidectomy.

Background: Parotidectomy is the treatment of choice in many parotid tumors. Due to the extensive nature of the procedure, unfavorable complications such as gustatory sweating, surgical site depression are common. Various techniques using fascia, muscle or AlloDerm have been developed but debate still remains regarding its availability and affordability.

Eccrine porocarcinoma on the cheek.

Eccrine porocarcinoma is a rare malignant tumor arising from the intraepidermal ductal portion of the eccrine sweat gland. It develops either spontaneously or from a long standing benign eccrine poroma. This entity usually affects older people and is commonly located on the lower extremities, the trunk, and the head.

Intraparotid facial nerve schwannomas.

Schwannoma is a benign tumor rarely found in the head and neck and much less commonly found in the intraparotid facial nerve. It is a slow-growing encapsulated tumor originating from the Schwann cells or axonal nerve sheath. It can occur anywhere along the course of the facial nerve.

Successful replantation of an amputated helical rim with microvascular anastomosis.

Replantation using microvascular anastomosis is considered to be the optimal method in treating the amputated ear in terms of resulting color, texture, and shape. Only a few cases of ear replantation have been reported because it is anatomically difficult to identify suitable vessels for anastomosis. We successfully replanted the amputated helical rim of the ear using single arterial anastomosis.

Giant Lymphatic Malformations in Lower Extremity in an Adult: A Case Report.

Lymphatic malformations are benign vascular malformations rarely seen in adults. There have been only around 100 cases reported in the literature, most of them located in the head and neck area. The etiology is poorly understood but trauma, infection, or tumors have been suggested as possible causes.

Skeletal cavernous hemangiomas of the frontal bone with orbital roof and rim involvement.

Skeletal cavernous hemangiomas are rare, benign tumors that may involve the supraorbital rim and orbital roof. However, such involvement is extremely rare. We report a case of skeletal cavernous hemangioma of the frontal bone involving the orbital roof and rim.

Cutaneous intramuscular lipoma: A new subtype of intramuscular lipoma.

Intramuscular lipoma is an uncommon variant of lipoma that occurs inside muscle tissue. Pathogenesis is thought to be related to neoplastic activity of mesenchymal stem cells, but there still is not an established theory. This entity can be found in almost all areas of the body, mostly within or in connection with skeletal muscle tissue.

Sensate hypothenar perforator free flap for resurfacing large volar surface defect of the digit.

In this report we present a case of large sized volar surface defect of a digit reconstructed by hypothenar perforator free flap coverage. A 57-year-old male patient presented with a 5 × 2 cm sized avulsive injury on his left little finger involving near total loss of the volar surface. The perforator arteries of the hypothenar area were identified around 5-15% on the x-axis and 25-50% on the y-axis (y-axis: a line from the pisiform base to the metacarpophalangeal joint, x-axis: a line perpendicular to the y-axis.
