NUT Carcinoma of the Ethmoid Sinus: A Rare Case Report Highlighting Aggressive Behavior and Management Challenges.

NUT carcinoma is a rare, aggressive malignancy characterized by chromosomal rearrangements involving the NUTM1 gene. We present the case of a 47-year-old male with a history of hypertension, diagnosed with NUT carcinoma originating in the ethmoid sinus and accompanied by extensive neck metastases. The patient underwent a left modified radical neck dissection and endoscopic nasal tumor excision, followed by concurrent chemoradiotherapy.

Parapharyngeal Ganglioneuroma Detected by 18F-FDG PET/CT in a Patient With Hodgkin Lymphoma.

A 38-year-old woman with anterior mediastinal Hodgkin lymphoma underwent F-FDG PET/CT, revealing abnormal uptake at the left retrostyloid parapharyngeal space. After chemotherapy, follow-up PET/CT showed regression of previously avid lesions but not the left retropharyngeal mass. Subsequent MRI revealed findings suggestive of neurogenic tumor.

Neck xanthogranuloma mimicking malignancy in a patient with diabetes mellitus: A case report and literature review.

Occurrences in the neck are extremely rare and would usually be associated with a preexisting cyst or glandular tissues.
