Endoscope-Assisted Resection of Intramuscular Cavernous Hemangioma Within the Temporal Muscle

Hemangiomas are benign vascular soft tissue tumors, which most frequently occur in the skin or subcutaneous tissue. Intramuscular hemangiomas typically occur in the trunk and extremities and less frequently in the head and neck. Among these, those occurring in the temporalis muscle are extremely rare. The authors report the case of a 43-year-old Japanese male with a mass in his left temporal fossa. Computed tomography images showed no erosion of the zygomatic bone, and magnetic resonance imaging revealed an ovoid well-marginated mass within the temporal muscle. The lesion was surgically excised with an endoscopy procedure used for minimally invasive lesions and complete removal. Histopathological examination confirmed the diagnosis of intramuscular cavernous hemangioma. The postoperative clinical course was good, with no indications of temporary nerve paralysis. No signs of local recurrence were observed postoperatively. Therefore, a cavernous hemangioma should be suspected when a mass occurs in the temporal region with accompanying radiologic findings suggesting vascular origin. In surgical treatment, the endoscopy-assisted technique is very useful to achieve complete tumor resection and prevent relapse while avoiding serious complications due to surgical procedures.

CONCLUSIONS: Although these like-tumor lesions are uncommon, pediatric dentistry practitioners must be familiar with the inherent clinical characteristics, diagnosis approaches, and currently available treatment options. Nowadays, surgical removal and non-invasive medical/pharmacologic therapies are the best management modalities for pediatric oral hemangiomas. PMID: 31967983 [PubMed - as supplied by publisher]

We describe a comprehensive, multidisciplinary treatment approach for lumbar vertebral hemangiomas (VHs) with spinal stenosis and radiculopathy. A 59-year-old female presented with 1 year of pain predominantly in the lower back, with pain in the left buttock and proximal left anterior thigh as well and magnetic resonance imaging of the lumbar spine demonstrated lumbar scoliosis and an L3 vertebral lesion suspicious for hemangioma. A computed tomography guided biopsy was done, which supported the diagnosis. Definitive treatment entailed preoperative angiography and embolization, followed by L3 laminectomy, right L3 pedicle ...

We present a rare case of a neonate with PHACES syndrome (posterior fossa malformations, large facialhemangiomas, cerebralarterial anomalies,cardiovascular anomalies,eye anomalies andsternal clefting orsupraumbilical raphe) and diffuse hemangiomatosis of the ileum, presenting with multiple intestinal perforations and peritonitis. The infant was successfully treated with propranolol and methylprednisolone as well as octreotide, tranexamic acid, and supportive therapy for massive intestinal bleeding.

Authors: Matsumoto M, Kasai T, Saito A, Takanobu K, Senoh H, Umeda Y, Kanno J Abstract Butyl 2,3-epoxypropyl ether (CAS No. 2426-08-6, synonym: n-butylglycidyl ether, BGE) was exposed by whole body inhalation to F344 rats and BDF1 mice of both sexes (50 animals per group) 6 hours per day, 5 days per week for 104 weeks at targeted concentrations of 0, 10, 30 or 90 ppm (v/v) for rats and 0, 5, 15 or 45 ppm for mice. In rats, 90 ppm of BGE increased the incidences of nasal squamous cell carcinomas in both sexes. Nasal adenomas and splenic mononuclear cell leukemia were increased in male rats exposed to 30 ppm. Splenic...

Authors: Yang M, Yang X, Wang S, Xu L, Ke S, Ding X, Sun W, Gao J Abstract The goal of this study was to assess the role of high-mobility group box 1 (HMGB1)-induced endothelial cell (EC) pyroptosis in systemic inflammatory response syndrome (SIRS) following radiofrequency (RF) ablation of hepatic hemangiomas. We enrolled 76 patients with hepatic hemangioma who underwent RF ablation. Serum concentrations of HMGB1, interleukin (IL)-1β, IL-18 and lactate dehydrogenase (LDH) were determined at different time points. Immunohistochemistry staining (IHC) was performed to evaluate the expressions of HMGB1, NLRP3, cas...

While cavernous hemangioma are frequently observed in various tissues and locations in the body, mediastinal cavernous hemangiomas (CHMs) are rare, particularly in the middle mediastinum. Here, we report a case of a middle CHM which was diagnosed and treated in our hospital. A male patient age 57  years was admitted with a mediastinal circular low‐density lesion. Preoperative examination was performed with a subsequent diagnosis of a mediastinal lesion. The lesion was resected and post‐operative histopathology suggested that it was a cavernous hemangioma. Post‐operative recovery was uneventful, and a follow‐...

We present a large case series of 46 infants treated successfully with oral atenolol, a selective beta-1 blocker.ResumenEl propranolol, un betabloqueante no selectivo, sigue siendo la primera línea de tratamiento para el hemangioma infantil problemático. Sin embargo, aunque poco frecuente, un subgrupo de pacientes experimenta efectos secundarios indeseables, lo que despierta el interés sobre otros beta-bloqueantes selectivos. Presentamos una amplia serie de casos de 46 lactantes tratados con éxito con atenolol, un bloqueante selectivo beta 1.
