[Cranial osteomas of atypical localization]. / Kostniaki czaszki o nietypowej lokalizacji.

Osteomas have a very characteristic localisation and frequency of occurrence. Based on a representative materials the authors present literature review in which the sequence of occurrence of osteomas in paranasal sinuses is described. A very rare occurrence of osteomas out of the paranasal sinuses is stressed and the hypothesis of development of osteomas in the sinuses and latter migration of osteomas from sinuses to nasal cavities or orbit is mentioned. Three cases of untypical size and localization of osteomas are presented, in two cases the tumors have develop primary outside the paranasal sinuses and in one case the osteoma was present in both frontal sinuses and in the ethmoid labyrinth.

Ventriculosaccular lymphoepithelioma of the larynx: case report and literature review.

BACKGROUND: Lymphoepithelioma is a very rare neoplasm of the larynx. The authors have reviewed the available published literature on the subject and found eight studies on lymphoepithelioma. Lymphoepitheliomas derive from the epithelial and lymphatic tissues of the laryngeal ventricule. The rarity of the occurrence of lymphoepithelioma makes it difficult to define its clinical features and general treatment methods. METHODS: The authors present a description of a lymphoepithelioma located in the left laryngeal sacculus, extending into the pre-epiglottic space and infiltrating the epiglottis with an ulceration of its laryngeal surface. A total laryngectomy and a left radical neck dissection were performed. After surgery, radiotherapy treatment was applied to the left cervical and laryngeal areas. Two years after the initial radiotherapy, the patient died during palliative chemotherapy (for metastases). RESULTS: In patients with lymphoepithelioma of the larynx, the following can be observed: (1) bulging of the laryngeal ventricule, with or without ulceration of the laryngeal surface of the epiglottic mucosa; (2) early lymph node and remote matastases. CONCLUSIONS: In the early stages of lymphoepithelioma, radiotherapy is the method of choice. In advanced cases of lymphoepithelioma, radiotherapy supplements surgical treatment.

[The effect of laryngectomy on selected physiologic functions of the nose]. / Wplyw laryngektomii na wybrane czynnosci fizjologiczne nosa.

The paper is a continuation of the author's research on pathophysiology of the nose in patients subjected to total laryngectomy due to cancer of the larynx. The aim of the research was to discover how the condition of the nasal mucous and its physiology are affected by the elimination of the nose from the respiratory pathway which is the case in laryngectomy, and also the evaluation of the influence that the nose can exert on the physiology of the respiratory and circulatory systems, despite the elimination of the nose as a first section of the respiratory pathway. The research material was obtained from 110 patients who were subjected to total laryngectomy due to malignancy of the larynx and from a control group number of 30. The research was carried out before the surgery and in different periods after an operation. The condition of the nasal mucous was estimated on the basis of clinical examination including rhinoscopy, measurement of the warmth of the air in the nose and the temperature of the nasal mucous and also on the basis of observation of mucociliary transport. From patients who underwent laryngectomy a cytological material was obtained for examination. In all patients naso-cardiac and naso-pulmonary reflexes were examined. On the basis of the research it was stated that the morphological condition of the nasal mucous does not undergo significant changes despite the elimination of the nose from the respiratory pathway and the nose still maintains its potential ability to perform physiological functions. It can also be said that the elimination of the nose from the first section of the respiratory pathway not only does not remove reflex reactions from the side of the nose, but also often changes their course and character.

[Crystallization test in patients with head and neck neoplasms]. / Test krystalizacyjny u chorych z nowotworami zlosliwymi glowy i szyi.

The authors try to estimate a clinical value of crystallization test with cupric chloride solution. 21 patients with planoepithelial cancer of the head and neck, and 10 healty volunteers underwent the test. 71.5% of positive results was obtained in cases with the cancer, what suggest a high sensitivity of the analyzed test.

[Triton tumor]. / Guz trytona.

A lethal case of a very rare Triton Tumor is described in a 57 year old woman who was treated surgically and postoperatively radiated with Co-60. Finally an adjuvant chemotherapy was performed on her. The characteristic of the tumor and difficulties in diagnosis and management were pointed out.
