    Opis:
    Sarcoidosis is a systemic disease of unknown etiology. It is characterized by a formation of lumps known as noncaseating granulomas, which are not affected by necrosis. Typical collections of inflammatory cells may be found in any organ tissues but mainly in the lungs, skin or lymph nodes. Head and neck organs involvement is rare, although sarcoidosis can be found in lymph nodes, salivary glands, larynx and sinuses. A search was performed based on medical records of patients admitted to the Department of Otolaryngology within four previous years. We analyzed two cases of sarcoidosis of salivary glands (parotid and submandibular), two cases of larynx involvement and one case of lymphadenopathy due to sarcoidosis. Patients (4 women and 1 man), age range 26–76 years old, were directed to the Otolaryngology Department with neck lymphadenopathy or a suspicion of a neoplastic tumor of salivary gland or larynx. Only one patient had previous diagnosis of pulmonary sarcoidosis. Preoperative diagnostic procedures such as ultrasonography, biopsy, chest radiography did not suggest sarcoidosis on the initial assessment in other patients. Surgical removal of the pathological findings and histopathological examination confirmed extrapulmonary sarcoidosis. The computed tomography of lungs confirmed coexisting pulmonary sarcoidosis in only one patient.

    Opis:
    Introduction: Parotid gland neoplasms represent a heterogenous group of tumors, either benign or malignant. The diagnosis and management of parotid gland tumors is complicated by their relative infrequency and their diverse biologic behavior. Aim: The aim of this study is to investigate the epidemiological characteristics, the recurrence rates and the surgical approach employed for parotid gland tumors in Northern Greece. Material and methods: This is a single-center retrospective study. All patients admitted to the ENT department of “G. Papanikolaou” General Hospital of Thessaloniki from January 2012 to June 2019 with the diagnosis of parotid gland tumor were included in the study. Patients with incomplete charts and patients that underwent revision surgeries were excluded. Chi-squared tests were used to assess the associations between variables. Results: A total of 207 patients with a mean age of 54.97 (range 16–91) were included in the study. Benign neoplasms accounted for 87.9% of the cases. Warthin’s tumor was the most common neoplasm encountered, with an incidence of 46.8%, followed by pleomorphic adenoma (31.9%). There was a higher incidence of parotid gland tumors in males and smokers (P = 0.025, P = 0.001 respectively). The majority of the patients were treated with an extracapsular resection (60.4%) or with a partial superficial parotidectomy (22.6%). In 12 cases (5.7%), there was a recurrence of the lesion. The most common complications encountered were facial nerve injury, Frey’s syndrome and hematoma formation. Conclusions: Parotid gland tumors are typically benign, non-aggressive tumors, more frequently seen in men than women. There is a positive association between smoking and parotid gland tumor development. Comprehensive information regarding recurrence and complication rates is presented.

    Opis:
    Introduction: Warthin’s tumor is a non-malignant tumor that occurs in major salivary glands. Diagnostics include an interview and physical examination as well as additional tests – ultrasonography, magnetic resonance tomography, fine-needle aspiration biopsy. Surgical tumor resection remains the method of treatment, the scope of which includes techniques from extracapsular tumor resection to a full range of parotidectomy. Material and methods: A retrospective analysis was conducted for available medical records of 53 patients treated surgically at the Department of Otolaryngology and Laryngological Oncology at the Collegium Medicum of the Nicolaus Copernicus University in Toruń in 2009–2016. Each patient underwent an interview, physical examination and a routine ultrasound examination. Results of treatment of 57 tumors were analyzed. Results: The study showed that in the case of extracapsular tumor excision in 57 patients in the treatment of Warthin’s tumors of the lower pole of the parotid lobe, there were no complications in the form of: permanent paralysis or facial nerve palsy, mucocele, symptoms of Frey’s syndrome or cosmetic facial defect. Ultrasound examination performed in 8 (14%) patients revealed lesions requiring further diagnostics or periodic ultrasound monitoring. Conclusions: 1. Extracapsular tumor excision appears to be an accurate surgical technique in Warthin’s tumor of the lower pole of the parotid gland’s superficial lobe. 2. After removal of a cancerous lesion of the parotid gland, every patient requires periodic laryngological monitoring.

    Opis:
    Pleomorphic adenoma, also known as tumor mixtus, is one of the most common types of benign neoplasm of the salivary gland, which presents as a slow growing, painless tumor. Major salivary glands are the typical localization of this neoplasm. It rarely undergoes malignant transformation, however may recur locally post resection. In this study, we present the results of a retrospective analysis of 104 patients treated at the Clinical Department of Cranio-Maxillofacial Surgery, Clinic of Otolaryngology and Laryngologic Oncology of the Military Institute of Medicine between 2004 and 2015 due to pleomorphic adenoma. The study confirmed the parotid gland as the most common location of tumor mixtus. In some cases, the large size of the tumor and its location were the cause of life-threatening complications.

    Opis:
    Introduction: Tumors of large salivary glands constitute about 2–3% of all head and neck tumors. Their incidence is statistically greater in males than in females, with the first symptoms usually appearing between the 4th and 7th decade of life. Aim: The aim of the study was to assess the usefulness of the new classification proposed by European Salivary Gland Society (ESGS) in comparison with the divisions of procedures previously valid in the literature, making a retrospective analysis of patients operated on due to benign tumors of large salivary glands in the Department of Otolaryngology, Head and Neck Oncology of the Medical University of Lodz in 2012–2020. Material and methods: The retrospective examination was based on the material consisting of: surgical protocols, histopathological results, imaging results and clinical observations. The material includes 283 patients (141 women and 142 men): 249 patients with parotid gland tumor and 34 patients with submandibular gland tumor. The most common histopathological diagnosis was pleomorphic adenoma, which was found in 105 patients (42.17%) and adenolymphoma diagnosed in 94 patients (37.75%). Results: The most common type of surgery was superficial parotidectomy including total superficial parotidectomy in 86 patients (34.54%) and partial superficial parotidectomy in 49 cases (19.68%). Then, according to the frequency of surgery, extracapsular tumor dissection (ECD) was performed (91 patients – 36.55%). According to the ESGS classification, in most cases parotidectomy I, II (37.34% of all parotidectomies) and parotidectomy II (28.49%) were performed. In case of ECD, all tumors were located at level II. Conclusions: In summary, the new classification is aimed at unifying, but also simplifying the current nomenclature, reducing the existing nomenclature errors. Determination of the exact location and extent of the tumor within the parotid gland facilitates postoperative monitoring of patients by ENT doctors and those of other specialties.

    Opis:
    Introduction: Neoplasms of the parotid glands constitute about 6% of head and neck tumours, the most common of which are: adenoma multiforme and Warthin’s tumor. Schwannoma is benign, encapsulated tumor of the nerve cells (lemocytes, Schwann cells), most often it occurs in the trunk, head, extremely rarely observed in the parotid gland. 9% Schwannomas derives from the facial nerve sheath, constituting from 0.5–1.2% of all salivary gland tumors. The literature describes 80 cases of intraparotid Schwannoma. Malignant Schwannoma (MPNST) account for 5% to 10% of all soft tissue sarcomas. Highgrade MPNST tumors are aggressive, with a tendency to relapse and metastasis. Case report: We present a case report of a 84-year-old female patient presented to the Head and Neck Oncology Clinic of the Medical University of Lodz, due to the painful tumor of the left parotid region. The tumor appeared six months before hospitalization. During the physical examination, there was a polycyclic tumor with reduced mobility, the skin on the tumor was slightly red, lymph nodes uninvolved, facial nerve function preserved. BACC revealed tumour tissue composed of sheets and spindle-shaped cells. The patient was qualified for surgical treatment. Under the general anesthesia the superficial lobe of the parotid gland along with the tumor was removed. After the procedure, no facial nerve palsy was found. The patient did well post-operatively and was discharged home on the 8th day after surgery. Immunohistochemical staining showed the tumour cells to be diffusely and strongly immunoreactive for S-100 protein and Ki67 40–50%. Strong and diffuse staining for S-100 protein were consistent with the malignant peripheral nerve sheath tumour (MPNST). The patient was referred for radiotherapy, due to the postoperative outcome and advanced age, no adjuvant treatment was proposed. The patient has been in observation for 1 year. No relapse was found in the follow-up studies.
    Wprowadzenie: Guzy ślinianki przyusznej stanowią ok. 6% nowotworów głowy i szyi. Najczęstsze z nich to: gruczolak wielopostaciowy i guz Warthina. Schwannoma jest zmianą wywodzącą się z komórek osłonki nerwów obwodowych (lemocytów, komórek Schwanna); najczęściej dotyczy tułowia i głowy, wyjątkowo rzadko obserwowany jest zaś w śliniance przyusznej. 9% Schwannoma pochodzi z osłonki nerwu twarzowego, stanowiąc od 0,5–1,2% wszystkich guzów ślinianek. W literaturze opisano 80 przypadków wewnątrzśliniakowych Schwannoma. Transformacja złośliwa dotyczy 14%. Złośliwe Schwannoma (MPNST) stanowią od 5% do 10% wszystkich mięsaków tkanek miękkich. Nowotwory MPNST o wysokim stopniu złośliwości są agresywne, z tendencją do wznowy oraz przerzutowania. Opis przypadku: Prezentujemy opis przypadku 84-letniej pacjentki, która zgłosiła się do Kliniki Nowotworów Głowy i Szyi UM w Łodzi z powodu bolesnego guza lewej okolicy przyusznej. Wspomniana zmiana pojawiła się 6 miesięcy przed hospitalizacją. W badaniu przedmiotowym stwierdzono policykliczny guz o ograniczonej ruchomości, skóra nad guzem była lekko zaczerwieniona, węzły chłonne niepowiększone, funkcja nerwu twarzowego zachowana. W BACC atypowe komórki wrzecionowate, budzące podejrzenie rozrostu złośliwego. Chora została zakwalifikowana do leczenia operacyjnego. W znieczuleniu ogólnym usunięto płat powierzchowny ślinianki przyusznej wraz z guzem i zmienioną skórą. Po zabiegu nie stwierdzono porażenia nerwu twarzowego. Przebieg pooperacyjny prawidłowy, pacjentka wypisana do domu w 8. dobie po zabiegu w stanie ogólnym i miejscowym dobrym. Wynik badania histopatologicznego materiału pooperacyjnego: dobrze odgraniczony wrzecionowaty guz z polami martwicy, profil immunohistochemiczny: S100+; Ki67 40–50%. Rozpoznanie – MPNST. Pacjentka została skierowana na konsultację radioterapeutyczną. Z uwagi na wynik pooperacyjny oraz zaawansowany wiek, nie zaproponowano leczenia adiuwantowego. Chora pozostaje w obserwacji 1 rok. W badaniach kontrolnych nie stwierdzono wznowy.
