Thyroid B-Cell Lymphoma in the Background of Hashimoto's Thyroiditis: A Case Report and Literature Review.

Primary thyroid lymphoma (PTL) is a rare type of thyroid cancer, comprising less than 5% of all thyroid cancer cases. PTL includes subtypes like diffuse large B-cell lymphoma (DLBCL) and mucosa-associated lymphoid tissue lymphoma (MALT). The connection between PTL and autoimmune diseases of the thyroid, particularly Hashimoto's thyroiditis, has gained recognition in recent years.

Nasopharyngeal Branchial Cleft Cyst: A Rare Case Report and Literature Review.

Branchial cleft cysts are birth defects that happen when the first through fourth pharyngeal clefts do not close properly and most of these cysts develop from the second cleft. Second branchial cleft cysts are almost always in the neck, so it is rare for them to present in the nasopharynx. We report an extremely rare case of a branchial cleft cyst that is located in an unusual site in the nasopharynx in a 36-year-old male with no prior medical history.

Giant Cell Reparative Granuloma of Parotid Region Infiltrating the Zygomatic Bone: A case report.

Introduction: Giant cell reparative granuloma is a rare, locally benign tumor with an aggressive behavior resembling malignant neoplasm, originating mainly from the mandible and maxilla; however, it can originate from other sites, such as zygomatic and temporal bones, with a young adult female predilection.

Case Presentation: A 28-year-old female presented to the Department of Otolaryngology and Head and Neck Surgery with a history of a slowly enlarging swelling over the left parotid region for four months. Physical examination revealed a non-erythematous, non-tender, firm mass with no overlying skin changes.

Accuracy of (18) FDG PET-CT for treatment evaluation 3 months after completion of chemoradiotherapy for head and neck squamous cell carcinoma: 2-year minimum follow-up.

Background: The purpose of this study was to assess the accuracy of (18) F-fluorodeoxyglucose positron emission tomography ((18) FDG PET)-CT in detecting residual or recurrent disease after nonsurgical treatment for head and neck squamous cell carcinoma (HNSCC).

Methods: We conducted a retrospective analysis of patients with oral cavity, oropharynx, larynx, hypopharynx, or cervical lymph node location of SCC treated with chemoradiotherapy. Twelve weeks posttreatment, (18) FDG PET-CT results were compared to histology if residual disease was suspected.
