Management for lymphatic malformations of head and neck. Frontiers in neurology Background:To explore the management of lymphatic malformation in head and neck. Methods:This is a retrospective study at a single center. Data on demographic, surgery, sclerotherapy and follow-up information were collected from our Vascular Anomalies Center database. Patients with lymphatic malformation of head and neck who had undergone surgery and sclerotherapy between March 2020 and March 2024 were included. Results:There were 94 patients in this study, the lesion sites included head ( = 60), tongue ( = 7), neck ( = 41), pharynx ( = 7), and head and neck ( = 7). Symptoms included bleeding ( = 6), infection ( = 2), dyspnea ( = 2), dysphonia ( = 4), and dysphagia ( = 4). Lymphatic malformation included macrocystic ( = 61), microcystic ( = 12) and mixed ( = 21). Surgeries for LM included radical resection, subtotal or partial resection and staged surgeries. Sclerotherapies included bleomycin monotherapy and combined sclerotherapy with ethanol and bleomycin, under ultrasound or fluoroscopy guidance. The follow-up period was from 3 months to 1 year. The therapeutic effect was evaluated according to the size of the treatment area. 55 patients, 21 patients, 11 patients and 7 patients were evaluated with excellent, good, moderate and no response, respectively. Conclusion:Surgical resection, sclerotherapy and the combination of the two are efficacious treatment modalities for head and neck LM. Combined with oral drugs and other new therapies may be warranted in future for challenging conditions. 10.3389/fneur.2024.1450102

Usefulness of ultrasound in dermatofibrosarcoma protuberans and correlation with histopathological findings: A series of 30 cases. Diago Adrian,Llombart Beatriz,Serra-Guillen Carlos,Arana Estanislao,Guillén Carlos,Requena Celia,Traves Victor,Bancalari Bernardo,Bernia Eduardo,Ríos-Viñuela Elisa,Sanmartín Onofre Skin research and technology : official journal of International Society for Bioengineering and the Skin (ISBS) [and] International Society for Digital Imaging of Skin (ISDIS) [and] International Society for Skin Imaging (ISSI) BACKGROUND:Small series of ultrasound findings in dermatofibrosarcoma protuberans (DFSP) have been published, but the usefulness of this technique as a preoperative planning tool for tumor resection has not been studied. MATERIALS AND METHODS:We retrospectively reviewed patients with DFSP at our hospital that underwent ultrasound examination. Depth of invasion was evaluated by ultrasound and histopathology. Accuracy of ultrasound for assessing depth of tumor invasion was estimated. RESULTS:Thirty histopathologically confirmed DFSPs were studied. Classic finger-like projections were observed in 73.3% of cases. A posterior hyperechoic area extending deep into the subcutaneous tissue correlated with the honeycomb DFSP pattern and was observed in 53.3% of patients. Concordance between ultrasound and histopathologic depth measurements was excellent. Lateral tumor extension and Doppler activity were not evaluated in our series. CONCLUSION:Ultrasound showed excellent prediction of depth of invasion. Further studies are required to define the usefulness of ultrasound for determining lateral tumor extension. 10.1111/srt.13003
