Obesity-induced Upper Extremity Lymphedema
Summary: Obesity increases the risk of upper extremity lymphedema following treatment for breast cancer and can cause lower extremity lymphatic dysfunction in extremely obese individuals. We report the first patient with obesity-induced upper extremity lymphedema. A 62-year-old man with a previous body mass index (BMI) of 105.6, presented with a BMI 60.3 following weight loss. He complained of lymphedema of all 4 extremities, which was confirmed by lymphoscintigraphy. Because the upper limbs are more resistant to lymphedema than the lower extremities, a higher BMI threshold may be necessary to cause upper extremity lymphatic dysfunction

Combined Lymphedema and Capillary Malformation of the Lower Extremity
Background: Primary lymphedema and capillary malformation are independent vascular malformations that can cause overgrowth of the lower extremity. We report a series of patients who had both types of malformations affecting the same leg. The condition is unique but may be confused with other types of vascular malformation overgrowth conditions (eg, Klippel–Trenaunay and Parkes Weber). Methods: Our Vascular Anomalies Center and Lymphedema Program databases were searched for patients with both capillary malformation and lymphedema. Diagnosis of lymphedema–capillary malformation was made by history, physical examination, and imaging studies. Because lymphedema–capillary malformation has phenotypical overlap with other conditions, only patients who had imaging confirming their diagnosis were included in the analysis. Clinical and radiological features, morbidity, and treatment were recorded. Results: Eight patients (4 females and 4 males) had confirmed lymphedema–capillary malformation. Referring diagnosis was Klippel–Trenaunay syndrome (n = 4), diffuse capillary malformation with overgrowth (n = 3), or lymphatic malformation (n = 1). The condition was unilateral (n = 6) or bilateral (n = 2). Morbidity included infection (n = 6), difficulty fitting clothes (n = 6), bleeding or leaking vesicles (n = 5), leg length discrepancy (n = 4), and difficulty ambulating (n = 3). All patients were managed with compression regimens. Operative management was liposuction (n = 3), treatment of phlebectatic veins (n = 3), staged skin/subcutaneous excision (n = 1), and/or epiphysiodesis (n = 1). Conclusions: Lymphedema and capillary malformation can occur together in the same extremity. Both conditions independently cause limb overgrowth primarily because of subcutaneous adipose deposition. Compression garments and suction-assisted lipectomy can improve the condition. Lymphedema–capillary malformation should not be confused with other vascular malformation overgrowth diseases that have different morbidities and treatments

Expression Analysis of Macrodactyly Identifies Pleiotrophin Upregulation
Macrodactyly is a rare family of congenital disorders characterized by the diffuse enlargement of 1 or more digits. Multiple tissue types within the affected digits are involved, but skeletal patterning and gross morphological features are preserved. Not all tissues are equally involved and there is marked heterogeneity with respect to clinical phenotype. The molecular mechanisms responsible for these growth disturbances offer unique insight into normal limb growth and development, in general. To date, no genes or loci have been implicated in the development of macrodactyly. In this study, we performed the first transcriptional profiling of macrodactyly tissue. We found that pleiotrophin (PTN) was significantly overexpressed across all our macrodactyly samples. The mitogenic functions of PTN correlate closely with the clinical characteristics of macrodactyly. PTN thus represents a promising target for further investigation into the etiology of overgrowth phenotypes

Resolution of Primary Lymphedema: A Case Report
Summary: Primary lymphedema is a rare, progressive disease that typically affects the lower extremity. The condition is not curable, and the limb enlarges over time because of subcutaneous fibroadipose deposition. We present a patient with clinical and radiographical evidence of resolution of primary lymphedema. This observation may provide greater insight into the pathophysiology of the disease

Abstract P11: Pediatric Orbital Floor Fractures: Clinical and Radiological Predictors of Tissue Entrapment and the Effect of Operative Timing on Ocular Outcomes
Operative management of vascular anomalies/ edited by Arin Greene, MD, MMSc, Department of Plastic and Oral Surgery, Lymphedema Program, Boston Children's Hospital, Harvard Medical School, Boston, Massachusetts
Includes bibliographical references and indexVascular anomalies are common lesions affecting at least 5% of the population. Patients often require multi-disciplinary care. This is a ""how-to"" text that illustrates the principles and techniques for the surgical management of vascular anomalies. The book covers the entire field of vascular anomalies. In addition, the text describes the operative management of these lesions in different anatomical locations. The book was designed so that it can be easily referenced, and contains classification, operative principles, figures, and video provided by experts in the field1 online resource (xiii, 262 pages)
