Tularemia is a zoonotic bacterial infectious disease caused by a gram-negative coccobacillus namely Francisella tularensis. In humans, disease leads to several different clinical forms (ulceroglandular, glandular, oculoglandular, respiratory, typhoidal and oropharyngeal). Since the main mode of transmission of the disease to humans in Türkiye is by drinking water contaminated with F.tularensis, the oropharyngeal form is the most common clinical manifestation. Since tularemia cases with pregnancy are rare, the literatüre about maternal and fetal complications of tularemia is sparse...

BACKGROUND: The tumor localization/extent and imaging characteristics of rhabdomyosarcomas (RMSs) especially parameningeal type, could overlap with the common tumors of the head and neck (H&N) such as lymphoma and nasopharyngeal carcinoma (NPC). Our goal was to investigate magnetic resonance imaging (MRI) features that could favor the diagnosis of RMS over lymphoma and NPC in H&N region. METHODS: Pretreatment MRI of 42 pediatric patients (mean: 9.7±5.1 years, min-max: 2-18 years) with a recent diagnosis of RMS (n=12), lymphoma (n=14) and NPC (n=16) were retrospectively studied...

Nasopharyngeal Hodgkin's lymphoma is a rare disorder. We describe a case of a 24-year-old male with Hodgkin's lymphoma (HL) primarily originating from the nasopharynx. He presented with symptoms including snoring and bilateral nasal congestion. After evaluation, endoscopic surgery was performed. Surprisingly, the pathological result proved to be classic HL. Postoperative MRI showed that the tumor was completely resected, and PET-CT was further examined. No lesions were found in other places. Shortly thereafter, the patient was transferred to the hematology department for chemotherapy, and the patient was followed up for 5 months without tumor recurrence...

Nasopharyngeal MALT lymphoma is a rare disease, with limited cases reported in the literature. To the best of our knowledge, there is no research detailing the treatment of nasopharyngeal MALT lymphoma. In this present paper, we report an unusual case of a 70-year-old female patient with nasopharyngeal MALT lymphoma. The patient was treated with radiotherapy alone. The detailed radiation therapy of the treatment was demonstrated. The patient is free of locally recurrent or distant disease at two years. Radiotherapy alone can be a helpful treatment for MALT lymphoma confined to the nasopharyngeal cavity...

Introduction: Nasopharyngeal carcinoma (NPC) is a nasopharyngeal epithelial neoplasm that has distinct aetiological, epidemiological and biological characteristics compared to other head and neck malignancies. Patients usually present late due to non-specific symptoms and deep location of the tumour in the nasopharynx. Case Report: We would like to highlight a case of advanced NPC presenting with generalised lymphadenopathy, without the presence of an obvious nasopharyngeal mass that masqueraded as lymphoma in the initial stage...

A man with history of chronic lymphocytic leukemia (CLL) in remission had multiple rapidly growing lumps in recent 2 months. FDG PET/CT demonstrated disseminated FDG-avid nodal and extranodal lesions including those in unusual locations such as the nasopharynx, salivary glands, lungs, gastric wall, peritoneum, bones, and muscles. Subsequent biopsy of the right axillary mass showed absolute lymphocytosis with focus of large B-cell lymphoma. Flow cytometric immunophenotyping demonstrated κ-restricted CLL and B-cell lymphoma, consistent with Richter transformation of CLL...

Extranodal NK/T cell lymphoma (ENKL) is a rare subtype of lymphoma that shows a poor clinical outcome. The most common sites are the nasal cavity, nasopharynx, paranasal sinuses, tonsils and larynx. Because of P-glycoprotein expression on ENKL cells, ENKL is resistant to anthracycline-based chemotherapy. L-asparaginase-based chemotherapy with or without radiotherapy shows promising outcomes for advanced ENKL, but has limited efficacy in relapsed/refractory ENKL. immune-checkpoint inhibitors, histone deacetylase inhibitors, and monoclonal antibodies are being investigated...

Epstein-Barr virus-infected B cells are found at high frequency in peripheral T cell lymphoma. Herein, we report a case involving excessive EBV-positive B cells accompanying peripheral T cell lymphoma, not otherwise specified in the nasopharynx masquerading as nasopharyngeal extranodal NK/T cell lymphoma. A large number of Epstein-Barr virus-infected B cells infiltrate in between CD3-positive cytotoxic tumor T cells, as if EBV was infecting tumor T cells. After chemotherapy, the T cell lymphoma population decreased, but the B cell population expanded to form EBV-positive diffuse large B cell lymphoma in the tonsils and nasopharynx...

Mantle cell lymphoma (MCL) is a subtype of B-cell lymphoma derived from CD5-positive antigen-naïve pre-germinal center B-cells within the mantle zone that surrounds normal germinal center follicles. MCL comprises approximately 5 to 10% of all lymphomas. Tonsil is the most common location of MCL in the head and neck region, followed by the nasopharynx. Primary MCL involving the nasopharynx is extremely rare. Its clinical course is very aggressive with frequent relapses after conventional chemotherapy. It always presents as a protruding mass on the mucosal lining of the pharyngeal cavity...
