Dermoid and epidermoid cysts in the oral cavity frequently develop in the midline or sublingual region of the floor of the mouth. Here, we report a rare case of an epidermoid cyst in the submandibular region. The patient was a 69-year-old man with a chief complaint of a mass in the right submandibular region. A mobile, elastic, relatively soft mass without tenderness was palpable in this region. The skin covering the mass was normal. MRI showed a cystic lesion measuring 3.5 × 3.0 cm under the platysma in the right submandibular region. Cystectomy was performed under general anesthesia. There was no adhesion to surrounding tissue and the right submandibular gland was preserved. The surgical specimen was cystic and contained soybean cord-like materials. Histopathologically, the cyst wall was lined by stratified squamous epithelium with no skin appendage, suggesting an epidermoid cyst. The postoperative course was uneventful and without recurrence after 28 months.

Background: Intranodal hemangiomas are rare benign vascular tumors of the lymph nodes, often misdiagnosed as malignant lymphadenopathies due to their clinical and radiological features. This case report and systematic review aim to elucidate the epidemiology, clinical profile, and therapeutic interventions for intranodal hemangioma, enhancing diagnostic accuracy and management.
Methods: A systematic review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines.

Background: Pharyngeal perforation has been documented as a consequence of substantial external force applied to the neck. Such trauma is frequently accompanied by additional organ injury and cervical fracture. In this report, we present an exceptionally rare instance in which minor blunt trauma to the neck resulted in pharyngeal injury without concomitant damage to other organs.

Introduction Surface electromyography (sEMG), a widely used noninvasive technique for assessing muscle activity, measures muscle activity during swallowing. However, changes in the activity of each swallowing-related muscle, depending on the materials swallowed, remain unclear. Therefore, we investigated changes in muscle activity in the submandibular region using a seven-channel sEMG when swallowing different materials.

We report the first travel-related case of a possible Mpox-Varicella zoster virus (VZV) co-infection in the Philippines, a country that is endemic for Varicella but non-endemic for Mpox. A 29-year-old Filipino, female, with a travel history to Switzerland and with no prior history of VZV infection sought consultation due to rashes. She presented with multiple papular, pustular, and vesicular skin lesions, some with umbilication and with irregular borders, on the face, neck, trunk, inguinal area, upper extremities, and right leg.

Objectives: Salivary gland cancer is a rare disease composed of more than 20 histological types with different grades of malignancy. The aim of this multicenter, retrospective study was to identify the most important predictors affecting recurrence and survival after surgery.
Material And Methods: A total of 543 patients with salivary gland cancers that underwent curative surgery between 2012 and 2022 in 13 institutions in northern Japan were evaluated in this study.
