Keratocystic odontogenic tumor (KCOT) is a benign cystic intraosseous tumor of odontogenic origin. An infection of a KCOT is not common because KCOT is a benign developmental neoplasm. Moreover, a severe deep neck space infection with compromised airway caused by infected KCOT is rare. This report presents a 60-year-old male patient with a severe deep neck space infection related to an infected KCOT due to cortical bone perforation and rupture of the exudate. Treatment of the deep neck space infection and KCOT are reported.

Descending necrotizing mediastinitis (DNM) is a severe, life-threatening infection that requires prompt diagnosis and aggressive surgical intervention. Management is particularly challenging when the condition is complicated by bilateral empyema and perivascular involvement. A 73-year-old woman presented with septic shock several days after experiencing pharyngeal pain.

First-bite syndrome (FBS) is manifested as acute and severe pain in the parotid region occurring at the first bite of a meal. While most cases of FBS arise after surgeries involving the deep lobe of the parotid gland, chemotherapy-induced FBS is extremely rare. Some adverse effects of oxaliplatin resemble FBS, suggesting it may be under-recognized.

Background: Cervical lymph node metastasis (LNM) is a well-established poor prognosticator of oral squamous cell carcinoma (OSCC), in which occult metastasis is a subtype that makes prediction challenging. Here, we developed and validated a deep learning (DL) model using magnetic resonance imaging (MRI) for the identification of LNM in OSCC patients.
Methods: This retrospective diagnostic study developed a three-stage DL model by 45,664 preoperative MRI images from 723 patients in 10 Chinese hospitals between January 2015 and October 2020.

The search for reliable prognostic markers in oral squamous cell carcinoma (OSCC) remains a critical need. Tumor-infiltrating lymphocytes (TILs), particularly T lymphocytes, play a pivotal role in the immune response against tumors and are strongly correlated with favorable prognoses. Computational pathology has proven highly effective for histopathological image analysis, automating tasks such as cell detection, classification, and segmentation.

Purpose: The main objective of this study was to conduct a radioanatomical study of the osteo-myo-cutaneous scapulo-dorsal pedicled flap.
Methods: A radiological study was performed to study the anatomical variations of the dorsal scapular pedicle (origin, course of the deep branch of the dorsal scapular artery (DSA) in relation to the medial border of the scapula, perforators from the superficial branch of the DSA). Perforators from the superficial branch of the DSA were also identified on anatomical subjects, and their cutaneous vascular territory was determined.
