RESUMO
BACKGROUND: Secretory carcinoma (SC) has been described as a distinct salivary gland tumor in the fourth edition of the World Health Organization (WHO) classification of head and neck tumors. SC is generally considered as a slow-growing low-grade malignant tumor, while several cases have been reported with high-grade features, and even metastases in the literature up until now. In this article, a soft tissue SC case is discussed with high-grade microscopic features and neural invasion. A review of the salivary gland SC cases with aggressive behavior is also debated. CASE PRESENTATION: A 65-year-old Caucasian man presented with a left neck mass for the past six months. The imaging studies demonstrated a very large cystic cervical mass (46 × 23 mm) with papillary projections in the anterolateral aspect of the left neck zone Vb. He underwent left radical neck dissection (level I-V) and was followed up for 12 months with the diagnosis of Secretory carcinoma. CONCLUSION: Although SC generally has a good outcome, multiple recurrences and unusual metastases may occur, which should be considered by either the pathologists or clinicians.

As a rare entity, sarcomas of the head and neck are challenging cases. In this paper, we represent a unique case of Ewing sarcoma of mandible, serving as an example of multidisciplinary team importance in a developing country.
RESUMO
INTRODUCTION: Antioxidants are essential elements in reducing the harmful effects of free radicals. The aim of this study was to compare the serum levels of total antioxidant before and after adenotonsillectomy procedure. MATERIALS AND METHODS: This study was conducted on 41 children with the age range 3-12 who underwent adenotonsillectomy. The total level of antioxidants was measured before and two months after adenotonsillectomy. RESULTS: The mean±SD level of serum antioxidants raised significantly from 11.17 (15.36) before surgery to 22.19 (10.87) IU/mL after surgery (P<0.001). The mean value was increased from 15.50 (17.97) to 24.89 (12.66) and 6.62 (10.67) to 19.36 (7.98) IU/ml among males and females, respectively. CONCLUSION: Adenotonsillectomy can efficiently increase the serum levels of total antioxidant among children with adenotonsillar hypertrophy. Moreover, it can improve the immune system against free radicals.
RESUMO
BACKGROUND: Bleeding during functional endoscopic sinus surgery always been a challenge for the quality of surgical field for surgeons. This study aimed to evaluate the effect of local nasal desmopressin premedication on blood loss and the quality of surgical field in functional endoscopic sinus surgery. METHODS: This study was conducted on 90 patients with chronic rhinosinusitis who were candidate for endoscopic sinus surgery. They were randomly assigned to two study groups. One group received a single puff of local desmopressin (10 µg) in each side of nasal cavity 30 min before the surgery and the other received normal saline instead. Blood loss and the quality surgical field were determined in 15, 30, 60 and 90 min during the surgery (scoring by BOEZAART grading system). All data were analyzed. RESULTS: Blood loss was significantly lesser in the desmopressin group (mean ± SD, 16.289 ± 5.605 ml) than in the control group (24.289 ± 5.2722 ml, P < 0.001).Surgeons were more satisfied with the surgical field in the desmopressin group than control group in all cutoff points (15, 30, 60, and 90 min during the surgery, P < 0.001). No side effects were observed using local desmopressin. CONCLUSIONS: Premedication with local desmopressin can reduce bleeding effectively and clear the surgical field during functional endoscopic sinus surgery.
