Adenoid Cystic Carcinoma of Pterygopalatine Fossa: Report of a Rare Case.

Adenoid cystic carcinoma (ACC) is an uncommon malignant neoplasm that predominantly arises from major and minor salivary glands, accounting for about 1% of head and neck malignancies. ACCs originating from the pterygopalatine fossa (PPF) are extremely rare. In this case report, we present a 77-year-old male patient who experienced a two-year hemi-facial numbness and mild trismus, with intact nasal mucosa.

Neurofibromatosis Type 1-Associated Malignant Peripheral Nerve Sheath Tumor in the Nasal Cavity.

Malignant peripheral nerve sheath tumors (MPNSTs) are rare soft tissue sarcomas, with 50% of cases associated with type 1 neurofibromatosis (NF-1). A 27-year-old male patient was referred to our department with an extended right nasal cavity MPNST. The lesion extended to the skull base, intracranial, parapharyngeal space, and infratemporal fossa.

Epigenetic editing and tumor-dependent immunosuppressive signaling in head and neck malignancies.

Head and neck cancer (HNC) comprises a heterogeneous variety of malignant tumors, characterized by a relatively high tumor mutation burden. Previous data have revealed that immune system dysfunction appears to serve a key role in the development and progression of HNC and established immunosuppression is vital for evading the host immune response. Despite progress in chemotherapy and radiotherapy, the survival rate of patients with HNC is still low.

[The use of acoustic rhinometry for the assessment of adenoid hypertrophy: a clinical study].

Objective: In our study, we employed the method of acoustic rhinometry for preoperative and postoperative (after adenoidectomy) evaluation of 25 children between 3-12 years of age who suffered from adenoid hypertrophy.

Material And Method: This method showed with accuracy the changes of the dimensions of the nasal cavity following the operation. The parameters which were evaluated prior and subsequent to the operation were the diameter of the nasal cavity in the area of the adenoids and the total volume of the nasal passage.
