The choice of surgical method appears to be independent of the osteoma size and the decision is likely to be taken based on the experience of the surgeon, available equipment and knowledge of different surgical techniques.

Patient: Female, 36-year-old Final Diagnosis: NK/T-cell lymphoma Symptoms: Nasal congestion • rhinorrea • sinus congestion Medication: — Clinical Procedure: — Specialty: Otolaryngology Objective: Rare disease Background: Extranodal natural killer (NK)/T-cell lymphomas are rare neoplasms that result in the destruction of mid-facial tissues. Infrequently seen in ear, nose, and throat clinical practice, they are often misdiagnosed and treated as chronic sinusitis, which delays proper diagnosis. This study aimed to describe the insidious course of NK/T-cell lymphomas, nasal type. Case Report: A 36-year-old woman with a 2-year history of recurrent exacerbation of chronic sinusitis and allergies was admitted to our clinic. Multiple endoscopic sinus surgical procedures were performed. Repeated histopathological tissue examinations revealed extranodal NK/T-cell lymphoma, nasal type. Positron emission tomography combined with computed tomography (PET-CT) was performed to assess the extent of the disease. The patient was treated with antibiotics, steroids, and antifungal drugs for many months before the definitive diagnosis was made. The patient was eligible for modified SMILE chemotherapy; however, the patient died suddenly from septic shock several days before the beginning of treatment. Conclusions: Chronic rhinosinusitis with progressive necrosis of sinonasal tissue that persists despite adequate antibacterial and antifungal treatment should prompt further investigation. In such cases, it is important to consider the diagnosis of NK/T-cell lymphomas, nasal type. Early diagnosis increases the opportunity for successful treatment.

A significant increase in the incidence of benign tumours, especially mixed and Warthin tumours, was demonstrated. There was no significant increase in the number of malignant tumours over the analysed period of time.

Aim of the studyLymphomas are a heterogeneous group of tumours of lymphoid tissue in which there is an abnormal proliferation of cells of the lymphatic system. The literature notes a gradual increase in the incidence of this type of cancer in the whole population. The aim of the study was to evaluate whether the above tendency occurs in the head and neck area.Material and methodsIn the years 2005–2014, at the Otolaryngology and Laryngological Oncology Department of the Upper Silesian Medical Centre in Katowice, 77 cases of lymphoma were recorded, 58 of which were analysed in terms of location, histological type, age and sex of the patient, and the presence of risk factors.ResultsThe vast majority of them were non-Hodgkin’s lymphomas (NHL) – 67.53%. Hodgkin’s lymphomas (HL) accounted for only a small fraction of diagnoses (7.79%). In terms of histopathological types, in most cases of NHL, there occurred diffuse large B-cell lymphomas (DLBCL) – 51.92%. The most common location was the lymph nodes, representing the location of the primary lesion in more than half of the cases. As regards the extranodal location, the Waldeyer ring dominated (54.54%) along with the palatal tonsil (40.90%).There has been a significant upward trend, especially in the incidence of NHL.

The most common form of non-invasive fungal sinusitis is the so-called fungus ball, which was also confirmed in our report (95% of the test subjects). AFRS is more likely to occur in warm, moist climates that favour the growth of fungi.
