Vascular tumors represent a challenging pathologic subset for surgical treatment as they show a propensity for profuse bleedings. This is especially applicable to the skull base region, where surgical access is difficult due to its complex anatomy. To overcome this problem, the authors introduced the use of a harmonic scalpel in endoscopic skull base surgery for vascular tumors. Here, the authors report the outcomes of endoscopic harmonic scalpel-assisted surgery in 6 juvenile angiofibromas and 2 hemangiomas. All surgeries were performed using Ethicon Endo-Surgery HARMONIC ACE 5 mm Diameter Shears. The median intraoperative blood loss was 400 mL (range: 200-1500 mL). The median length of hospital stay was 7 days (range: 5-10 days). Recurrence was recorded in 1 patient with juvenile angiofibroma, which was successfully resolved with revision surgery. In this institutional experience, ultrasonic technology showed precise cutting with minimal bleeding, resulting in reduced surgical morbidity compared with conventional endoscopic instruments.

Congenital intracranial hemangiomas are rare benign vascular tumors that develop before birth. Although various treatments, including surgery, steroids, interferon-α, thalidomide, bevacizumab, or propranolol, have been reported, no standard therapy has been established. We report the case of a neonate with congenital intracranial hemangioma and central nervous system symptoms requiring therapeutic intervention.

Background: Perivascular epithelioid cell tumors (PEComas) rarely appear in the head and neck region. This case report describes two transcription factor E3 (TFE3)-rearranged PEComa cases, consisting of one in the orbit and one in the nasal cavity.
Case Presentation: Both cases demonstrated sheet-like or focal nested architecture and comprised epithelioid cells with abundant clear to eosinophilic cytoplasm and vascular stroma.

Mast cells (MCs) are critical components of both innate and adaptive immune processes. They play a significant role in protecting human health and in the pathophysiology of various illnesses, including allergies, cardiovascular diseases and autoimmune diseases. Recent studies in tumor-related research have demonstrated that mast cells exert a substantial influence on tumor cell behavior and the tumor microenvironment, exhibiting both pro- and anti-tumor effects.

Surgical resection and postoperative adjuvant chemotherapy have enhanced the outlook for breast cancer patients. However, tumor relapse and serious side effects of chemotherapy continue to impact patients' quality of life. Designing injectable composite hydrogel made of biodegradable polymers providing sustained release of antiangiogenic and chemotherapeutic agents might play a vital role in elimination of cancer cells.
