Pleomorphic adenoma - 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.

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.

Temporal muscle flap in reconstruction of maxillo-facial tissues.

AIM OF THE STUDY: Presents our experience in reconstruction of postsurgical defects with use of temporal muscle flap. MATERIAL AND METHODS: In the years 1996-2010 we treated 10 patients with malignant neoplasms of maxillo-facial region. Following tumor removal the fascia-muscle flaps of temporal muscle were used for reconstruction. Temporal muscle flaps were applied in 5 cases for reconstructing the defect of eye socket tissue after extensive resections and in the other 5 patients was used for reconstructing the defect of palate following maxillary resections. RESULTS: All the flaps of temporal muscle that were used for reconstructing eye sockets incorporated with no local reaction. In one case of flap applied into the oral cavity for tightly separate from nasal, partial necrosis of flap's edge and oro-nasal fistula occurred. CONCLUSIONS: Fascia-muscular flap of temporal muscle is a simple, easy and effective method of tissue reconstruction in maxillo-facial region following extensive oncologic procedures.

Comparison of positron emission tomography/computed tomography imaging and ultrasound in surveillance of head and neck cancer - The 3-year experience of the ENT Department in Poznan.

BACKGROUND: Posttreatment surveillance for the local and regional recurrence of the head and neck squamous cell carcinoma often requires a multimodality techniques that include PET combined with CT, MRI, US. AIM: The purpose of this study is to compare the diagnostic performance of two imaging techniques (PET/CT and US), and their combined use for the detection of a subclinical regional recurrence in patients after HNSCC treatment. MATERIALS AND METHODS: 83 patients after completion of the HNSCC treatment underwent both US and PET/CT on the mean follow-up of 14 months after initial treatment. RESULTS: The sensitivity and specificity of PET/CT were 86% and 82%, respectively; US values reached 81% and 87%, respectively. PPV was 79% for PET/CT, and 83% for US. NPV was 89% for PET/CT, and 85% for US. The overall accuracy for PET/CT and US was 84% for both methods. CONCLUSION: US could be regarded as complementary to PET/CT as the procedures with highest sensitivity, specificity and NPV for detecting subclinical regional recurrences after HNSCC treatment.

An upper lip tumour as the presenting symptom of metastatic renal cancer.

INTRODUCTION: Renal cell carcinoma (RCC) constitutes about 3% of solid tumours in adults. Unfortunately, in spite of continuous development of more and more efficient diagnostic methods, in about 30% of patients with RCC metastatic spread is found at presentation. Only in 1% of patients with advanced RCC metastases are limited exclusively to the head-and-neck region. We present a case of a male patient in whom a tumour of the upper lip was the first symptom of advanced renal cancer. CASE REPORT: A 59-year-old male was admitted to the Urology Department due to a large tumour of the right kidney. About two months earlier the patient noted a nodule located within the upper lip. In the same period painless hematuria occurred twice, which was disregarded by the patient. A CT scan of the chest and abdomen showed a large tumour of the kidney, multiple lung and bone metastases. The patient underwent local surgical excision of the lip tumour and palliative renal artery embolization. CONCLUSIONS: In natural history of renal cancer there is a risk of metastatic spread to the head-and-neck region. Contrast enhanced computed tomography of the abdomen should be considered if a tumour of unknown origin is found within the head-and-neck region. Prognosis in case of confirmed metastatic renal cancer is unfavourable and patient's treatment should be conducted in specialist centres.

[Face cancer infiltrating of ethmoid-orbito-nasal complex]. / Raki plaskonablonkowe skóry twarzy naciekajace masyw nosowo-sitowo-oczodolowy.

Face cancer is one of the most common skin tumors and because of its locations is usually early diagnosed. In spite of this a lot of recurrence after surgical treatment are observed. It is caused a lack of proper margins in sequence of limitation excision because of esthetic and functional reasons. The recurrence of skin cancer primarily localized in periocular region and infiltrating intraorbital, ethmoidal and nasal tissues demand extensive and injurious surgical procedures. The authors present their experience in diagnostic and treatment patients with recurrent cancers infiltrating of ethmoid-orbito-nasal complex.
