Opis:: Malignant lymphomas represent approximately 5% of all malignant neoplasm of the head and neck and may involve nodal or extranodal sites. The head and neck region is the second most frequent anatomical site of extranodal lymphomas (after the gastrointestinal tract). Most are non-Hodgkin lymphomas (NHL) of B-cell lineage. Hodgkin's lymphoma (HL) rarely occurs in extranodal site.The aim of the study was to evaluate head and neck manifestation of lymphoma (both HL and NHL) and emphasize diagnostic difficulties of these pathologies.Material and methods. Retrospective review of medical records of patients diagnosed for lymphomas in our department was performed. Authors analyzed demographic data as well as clinical manifestation and diagnostic trials.Results. 9 patients were included to the study. 7 of them suffered from extranodal NHL and 2 of them from HL (one patient - extranodal and one nodal manifestation). There were diagnostic complications in all cases and final diagnosis was made after surgical material analysis.Conclusions. This data demonstrate low sensivity of fine needle aspiration for identification of lymphoma as well as clinical picture is non characteristic.

Opis:: Introduction: Dermoid cysts are benign epidermal tumors; in 7% of cases, they are located in the head and neck region. They are lesions of congenital origin, mostly presenting within the midline of the body. About 70% of cases are diagnosed before the age of 5 years. Methods: A retrospective analysis of medical data of children with dermoid cysts located within the head and neck region treated in the Department of Pediatric Otolaryngology in Bialystok in the period of 1994-2014 was performed. A review of relevant literature was presented. Results: A total of 17 patients were included in this study, with a mean age of 8.9 years; 76.5% of the study population was female. Dermoid cysts were mostly located in the anterior neck region and the floor of the mouth (76%). US and CT imaging scans were used in diagnostics. No recurrences were observed after surgical excision. Conclusion: Dermoid cysts should be taken into consideration when diagnosing head and neck masses in pediatric patients.

Tematy:: European Head and Neck Cancer Awareness Week
head and neck tumors
Opis:: Introduction: The aim of the study was to analyze the profile of patients who reported for free screening examinations during the 4th European Head and Neck Cancer Awareness Week to the Department of Otolaryngology, Miedzylesie Specialist Hospital, Warsaw, Poland. Material and methods: We enrolled 225 patients, aged 26-92 years (mean, 63 years). There were 149 women (66%) and 76 men (34%). All patients filled out a survey regarding risk factors of head and neck cancer (HNC), including symptoms and lifestyle characteristics. Subsequently, all participants underwent a complete laryngological examination. Results: Among the studied patients, we found the following lifestyle-related risk factors of HNC: tobacco use (22%), alcohol use more than 1 time per week (12%), oral sex (17%), multiple sexual partners (10%), rare dental checkups (24%), and dental prostheses (45%). The most frequent symptoms that prompted the patients to report for screening exams were as follows: chronic hoarseness (64%), xerostomia (39%), dysphagia (37%), nasal congestion (6%), and neck tumor (5%). Further imaging studies were ordered in 15 patients (7%), fiberoscopy in 25 (11%), and lesion excision in 18 (8%). Among the studied patients, 17 were referred for further oncological treatment, of whom 14 had benign tumors and 4 malignant tumors. Conclusions: The Head and Neck Cancer Awareness campaign increased the awareness of HNC, and it should systematically encompass people at increased risk. By implementing this program in our department, we were able to detect and initiate early treatment in 7.5% of the screened people. However, appropriate workup and treatment require funding and therefore systemic measures should be taken to enable a wide implementation of such screening programs.

Opis:: Neuroendocrine carcinoma is a rare neoplasm, and its most common location in the head and neck area is the larynx, especially the epiglottis and the supraglottic region. The first case of neuroendocrine carcinoma of the larynx was reported in 1969 by Goldman et al. Expression of the two crucial markers, synaptophysin and chromogranin, along with neural cell adhesion molecule (CD56) should be mentioned among the neuroendocrine features detected on immunohistochemistry. Human papilloma virus (HPV16/18) infection in the laryngeal neuroendocrine carcinoma can be one of the causal factors, and the detection of HPV should be considered as a standard procedure for the diagnosis and treatment.

Opis:: Paragangliomas are rare, most commonly non-malignant tumors of the autonomic nervous system. Their location within the head is rather an exception than a rule, similarly as their multifocal prevalence. The authors of this paper present a case of a patient with bi-focal paraganglioma. The first symptom of illness was facial nerve palsy, diagnosed for the period of about 3 years. After making the initial diagnosis of tympanic paraganglioma, the tumor was operated. During the next 7 years, there was a recurrence within the temporal bone. What is more, periodic imaging examination showed second foci within the neck, moreover asymptomatic. The authors discuss the natural development of paragangliomas in the region of head and neck and present the current knowledge about management of patients with a suspicion, diagnosis, and treatment of this disease.

Opis:: Alongside surgery, radiation therapy remains the mainstay of treatment for head and neck cancers. Because the head and neck contain a number of critically important structures, it is crucial to try to curtail the adverse effects of radiation therapy by increasing its precision. Such precise radiation techniques include the three-dimensional conformal as well as highly conformal radiotherapy. The latter includes, for instance, intensity modulated radiation therapy (IMRT), stereotactic radiation, and proton-beam therapy. All of the above-mentioned techniques are available in Poland and give the opportunity of a more aggressive treatment that lead to improved outcomes, curtailment of adverse effects, and by that, a better quality of life.

Opis:: Introduction: Malignant lymphoma (ML) is a neoplasm caused by clonal expansion of undifferentiated B, T and NK-lymphoid cells. WHO classification divides lymphomas into two main types, i.e. Hodgkin lymphoma (HL), and non-Hodgkin lymphoma (NHL), with numerous subtypes. The majority of MLs are localized in lymph nodes, but extranodal locations are also possible. MLs represent approximately 3-5% of all malignant neoplasms in Poland, but their incidence has been increasing in recent years, especially in young patients. The objective of the study was to evaluate clinical manifestations and diagnostic process in patients with malignant lymphomas of the head and neck region as diagnosed in the Department of Otorhinolaryngology of the Medical University of Lodz in years 2013-2017. Material and method: 30 patients diagnosed with malignant lymphomas of the head and neck region at the Departbadament of Otorhinolaryngology of the Medical University of Lodz in 2013-2017. Results: The study group consisted of 8 cases of nodal lymphomas and 22 cases of extranodal lymphomas. In 29 cases B-cell lymphomas were diagnosed. The most common symptoms included lymphadenopathy or neck tumor. Other symptoms were associated with the location of tumors in particular body organs. The diagnosis was based on histopathological examination of biopsy (needle or surgical) samples. Conclusion: Malignant lymphomas should be taken into account during differential diagnosis of the tumor or lymphadenopathy of the neck. The diagnosis is difficult because of the nonspecificity of symptoms and the need for interdisciplinary cooperation of many specialists.

Opis:: The neck posture of sauropod dinosaurs has long been controversial. Recent reconstructions position the cervical vertebrae and skull in an “osteological neutral pose” (ONP), the best fit arrived at by articulating the vertebrae with the zygapophyses in maximum contact. This approach in isolation suggests that most or all sauropods held their necks horizontally. However, a substantial literature on extant amniotes (mammals, turtles, squamates, crocodilians and birds) shows that living animals do not habitually maintain their necks in ONP. Instead, the neck is maximally extended and the head is maximally flexed, so that the mid−cervical region is near vertical. Unless sauropods behaved differently from all extant amniote groups, they must have habitually held their necks extended and their heads flexed. The life orientation of the heads of sauropods has been inferred from the inclination of the semi−circular canals. However, extant animals show wide variation in inclination of the “horizontal” semi−circular canal: the orientation of this structure is not tightly constrained and can give only a general idea of the life posture of extinct animals’ heads.

Opis:: Treating patients with squamous cell carcinoma of the head and neck is a significant problem. There is an increase in the incidence of malignant neoplasms in this region. Surgery, radiotherapy and chemotherapy are often not sufficient methods of treatment. Thorough analysis of processes occurring in the tumor microenvironment has allowed to distinguish three stages that make up the reaction of the human body to hostile antigens, which are tumor antigens. Understanding these mechanisms has resulted in the introduction of a new term immune-oncology. It is an area of cancer treatment that focuses on use of the patient’s immune system to combat the disease. Immunotherapy has had positive effects in cancer patients. The use of immune checkpoint inhibitors, such as anti-CTLA-4 and PD-1 monoclonal antibodies has enabled the modulation of T cell functions, consequently eliminating immunosuppression in the tumor microenvironment. Clinical trials were conducted using nivolumab and ipilimumab, which confirmed their clinical usefulness. The approval by FDA of nivolumab in treatment of recurrent and metastatic squamous cell carcinoma of the head and neck has increased the overall survival time of patients as well as disease free survival. Statistical data indicate an advantage of immunotherapy over other treatment methods at an advanced stage of cancer. This work aims to discuss basic issues related to immunotherapy, in particular immunotherapy in patients with squamous cell carcinoma of the head and neck.

Opis:: Elective tracheostomy before resection of a malignancy in head and neck region assures unobstructed ventilation during postoperative period but is associated with an increased risk of complications. We aimed to evaluate retrospectively, how the application of elective tracheostomy scales would influence the frequency of tracheostomy in comparison with preoperative clinical judgement. In 205 patients operated on from 2013 till 2017, theresection of a malignancy involved suprahyoid or pharyngeal muscles, neck dissection and flap reconstruction. The decision on elective tracheostomy was made on the clinical basis. Score for each patient in 3 published scales was calculated. In the study group 76 patients had elective tracheostomy at the outset of a resection procedure. Among 129 patients without elective tracheostomy, 9 had tracheostomy in the postoperative period. Indications for elective tracheostomy were calculated for scale I, II and III. Only in 120 patients the decision whether to perform elective tracheostomy would be identical in each scale. Our results suggest that decisions to perform elective tracheostomy based on 3 scales show low specificity. The factors used in the published scales should be evaluated in a prospective multicenter study
