Rare Case of a Cutaneous Fingertip Schwannoma: A Case Report and Review of Literature.

Background: Soft tissue masses of the hand are common and mostly benign, including ganglion cysts, glomus tumors, lipomas, and giant cell tumors of the tendon sheath. Schwannomas are benign nerve sheath tumors but are rarely found on the distal parts of the digits. The authors present a case of a schwannoma located at the tip of the finger. Methods: An otherwise healthy 26-year-old man presented because of a 10-year history of a slowly growing mass on the tip of his right little finger that significantly interfered with his right hand function. The patient underwent hand radiographs and surgical excision of the tumor. Results: Pathologic evaluation determined that the mass was a schwannoma with positive immunohistochemistry for S-100 and SOX-10. The patient reported complete resolution of symptoms associated with the tumor and his satisfaction with the surgical outcome. Conclusions: Imaging studies, such as radiographs, ultrasound, and magnetic resonance imaging, are critical in the diagnostic workup of soft tissue masses of the hand to better understand involvement of the tumor to musculature, vasculature, and other pertinent bony structures. Although quite common, schwannomas may be hard to differentiate from other soft tissue tumors, and a review of the literature demonstrates the importance of providers utilizing imaging and other diagnostics before proceeding to treatment.

Pediatric Replantation after Traumatic Amputation at the Distal Forearm: Rehabilitation Protocol and Outcomes.

Major limb replantation is a formidable task, especially in the pediatric setting. While meticulous microsurgical technique is required in the operating room, the authors aim to highlight the importance of postoperative rehabilitation therapy for optimal function. We highlight the case of a 12-year-old boy who suffered complete traumatic amputation through the distal left forearm. The limb was successfully replanted with successful restoration of sensation and function with the aid of intensive postoperative occupational therapy. A multidisciplinary team is of paramount importance to maximize function of a replanted upper extremity.

Treating Wounds With an Avascular Component With a Dermal Regenerative Template.

INTRODUCTION: Partially avascular wounds pose a challenge to wound care surgeons. OBJECTIVE: The authors reviewed the literature and institutional results on the use of a dermal regenerative template (DRT) over partially avascular wounds to quantify the ability of the DRT to vascularize over these wounds. MATERIALS AND METHODS: A review of the literature was performed using Ovid MEDLINE, Google Scholar, and Cochrane Library. Patient demographics, comorbidities, wound types, surface area of avascular tissues, and skin graft take were analyzed. A retrospective review of institutional cases was conducted. RESULTS: A total of 32 articles met inclusion criteria. The retrospective review included 26 patients with partially avascular wounds reconstructed with the DRT. Seventeen patients experienced 100% graft take, 6 experienced partial take, and 3 suffered complete loss. The percent and absolute size of avascular surface area in the wound was significantly lower in cases of complete graft take compared with partial take and complete loss (1.9% and 2.7 cm2; 9.3% and 10.0 cm2; 18.0% and 9.3 cm2, respectively, P ⟨ .001). Chronic wound status (P ⟨ .001) was significantly associated with less graft take. CONCLUSIONS: This literature review and retrospective study confirm the DRT is a viable option to provide vascularized coverage over wounds with avascular components. This study suggests the DRT is more reliable in wounds with less than 1.9% avascular tissues and less successful in chronic wounds.

The Impact of Metabolic Syndrome on Patients Undergoing Breast Reduction Surgery.

Metabolic syndrome affects 35% of individuals in the USA and has been correlated with increased complications following certain surgical procedures. There has been an increase of 11% in breast reduction procedures from 2016 to 2017 making it the seventh most common reconstructive procedure in the USA. Previous studies have identified an increase in demand for breast reduction among obese patients with BMI ≥ 30 but have not defined the role of metabolic syndrome in surgical outcomes. The authors aim to investigate the impact of metabolic syndrome on 30-day postoperative morbidity and mortality in patients who underwent reduction mammoplasty.

An incidental finding of pleomorphic adenoma of the minor salivary glands in the skin area of the lower lip.

Salivary gland tumors are uncommonly seen and account for less than 3% of the head and neck tumors. Pleomorphic adenoma is a well-described benign tumor of the salivary glands, originating from myoepithelial and intercalated duct cells. It is most commonly found in major salivary glands. We present a rare and unusual case of pleomorphic adenoma of the minor salivary glands in the lower lip. The tumor was diagnosed upon excision of 1.5 × 1.2 cm(2) well-circumscribed nodule at the junction of the lower lip and chin in a 46-year-old man. The histopathological analysis confirmed presence of an epithelial salivary gland tumor with islands of plasmacytoid cells, and duct-like structures within a variable and mixed stroma.

Examination of possible predictors of complications after free tissue transfer to the head and neck for oncologic defects.

INTRODUCTION: The advent of vascularized free tissue transfer marked an incredible addition to the breadth of options available to the reconstructive surgeon when treating head and neck defects. The goal of this study is to determine if readily available laboratory tests may be used to stratify the risk for developing complications after free tissue transfer in specific patients. METHODS: Institutional review board approval was obtained for a retrospective chart review of all patients who underwent free tissue transfer for reconstruction of oncologic head and neck defects between 2001 and 2010 by the senior author (R.O.D.). RESULTS: There were 107 free tissue transfers to the head and neck for oncologic defects during this period. A significant relationship was found between a preoperative hemoglobin less than 10 mg/dL and a postoperative albumin less than 2.5 mg/dL and complications. CONCLUSIONS: Preoperative hemoglobin less than 10 mg/dL and postoperative albumin less than 2.5 mg/dL seem to be useful as indicators of an increased likelihood of developing postoperative complications. Correction of these values preoperatively and postoperatively may lead to improved surgical outcomes.

Management of complicated wounds of the extremities with scapular fascial free flaps.

Management of complicated open wounds of the extremities represents a reconstructive challenge. The goal of reconstruction is to provide coverage of exposed vital structures with well-vascularized tissues for optimal restoration of its form and function. We present our experience with the use of scapular fascial free flaps in the reconstruction of complicated open wounds of the extremities. During the period 2001 to 2009, a total of 12 reconstructions utilizing scapular fascial free flaps were performed: nine for upper extremity wounds and three for lower extremity wounds. Two flaps failed: in one case due to intractable vasospasm, in the other case due to lack of adequate recipient vessels. In the ten successful cases, good functional and aesthetic outcomes were achieved. Based on our experience, we conclude that the scapular fascial free flap, although technically demanding, could be considered as the flap of choice for reconstruction of complicated open wounds of the extremities; it provides ample thin and well vascularized soft tissue coverage with restoration of function and a natural contour of the extremity.

Biobrane in the management of critical microsurgical wounds of the upper extremity.

PURPOSE: Evolving soft tissue necrosis and/or edema can complicate microsurgical reconstruction by leading to open wounds with exposure of critical structures: anastamosed vessels, nerves, and tendons. Not infrequently, primary closure of these wounds is not possible. Immediate skin grafting may lead to anatomical and/or functional failure of reconstructed structures, compromising immediate or long-term functional outcomes. In addition, local tissues are often unavailable, and free tissue transfer in those settings could be ill-advised, especially for small wounds. METHODS: All of the senior author's microsurgical cases were reviewed. Four cases of replantation and one microsurgical reconstruction, where biologic dressings were used to treat critical wounds, were identified and are presented in this study along with an algorithm for the management of these types of wounds. RESULTS: Biologic dressings are simple, effective, and reliable tools for intermediate treatment of critical microsurgical wounds. Flap or replant viability was preserved in 100% of cases without compromising functional results. CONCLUSIONS: Biologic dressings can be used safely to treat microsurgical wounds with exposed critical structures. This use of a biologic dressing greatly simplifies the management of these types of wounds, avoiding the need for complex surgical intervention.

Complications following expander/implant breast reconstruction utilizing acellular dermal matrix: a systematic review and meta-analysis.

BACKGROUND: The recent increase in popularity of acellular dermal matrix assistance in immediate expander/implant breast reconstruction has led to variety of viewpoints. Many studies are published indicating an increase in complications with the use of acellular dermal matrix, while others indicate there is no increase in complications. METHODS: This meta-analysis utilizes information from available studies that directly compare one specific type of acellular dermal matrix with traditional methods of immediate expander/implant breast reconstruction. Eight studies were found through a meticulous literature search that met these criteria. RESULTS: There was more than a 2-fold increase in the number of infections and explanations in the acellular dermal matrix group compared to the control. There was a 3-fold increase in seroma formation in the acellular dermal matrix group compared to the control. There was a significant difference of intraoperative fill volumes between the acellular dermal matrix group compared to the control. CONCLUSIONS: This study illustrates that after pooling all available date regarding the use of acellular dermal matrix in immediate expander/implant breast reconstruction there appears to be an increased rate of complications. However, the increased intraoperative fill volume may lead to ultimately greater patient satisfaction.
