This paper presents the case of a 58-year-old heavy smoker female who came to our clinic with acute pain, as well as mastication and feeding difficulties. The macroscopic examination revealed oral erosive lesions and ulcerations. The polymorphic aspect of the lesions required the differential diagnosis of oral erythroplakia or carcinoma, which were excluded by biopsy. At the same time, we assessed the expression of S100 protein, Ki67 and the cluster of differentiation (CD) 4, CD8 (T-cell) and CD20 (B-cell) immune cell markers by immunohistochemical analysis. As a result, after the clinical and pathological assessment, the diagnosis of oral lichen planus was established, and a therapy plan was conducted. We observed a favorable clinical evolution after the administration of corticosteroids and immunomodulatory agents.

Cystic hygromas (CHs) are benign congenital malformations of the lymphatic system mainly diagnosed in small children aged less than two years old. They may give a multitude of local, sometimes severe complications. The most used method of treatment is surgical removal. In this paper, we present the case of a CH of a 13-year-old boy, localized in the right lateral region of the neck, diagnosed through magnetic resonance imaging (MRI), with excellent results of the surgical treatment.

Background: The presence of metastatic cervical adenopathy is essential for treatment planning and prognosis assessment. Treatment of patients with head and neck cancer with clinically negative cervical lymphadenopathy (N0) remains controversial. Neck palpation, as the method used in tumor, node, metastasis (TNM) staging, has limitations and can provide false negative results in some cases. Lymph node metastases are associated with a reduced survival rate but at the same time, neck dissection for the patient with N0 neck is not without risks or complications. Objectives: In prospective study, we compared palpation, ultrasonography (US) examination of the neck and histopathological examination in patients with cancers of the pharynx and larynx. Patients, Materials and Methods: Forty-six patients with cancers of the pharynx and larynx that presented with a N0 neck were prospectively analyzed. They were divided in two groups: 23 patients operated with an external approach including the control of the lymph node areas, and a second group of 23 patients operated using endoscopy and carbon dioxide (CO2) laser, no neck dissection-"watchful waiting policy". All patients have had a flexible endoscopy of the pharynx and larynx, US of the neck and all received surgical treatment for their primary tumor. Imaging was performed in selected cases. All the removed lymph nodes were sent for histopathology. US was also used as a follow-up method. The US features of the examined lymph nodes were: diameters [longitudinal (L) and transverse (T)]; the ratio of the two diameters (L/T); shape; lymph node area; central hypodensity; regular/irregular margins; aspect (homogeneous or not). Results: US has detected 25 lymph nodes in the open surgery group and intraoperatively, we excised 31 (sensitivity of 80.6%). Ten lymph nodes showed metastases, with 100% accuracy of US, which have been confirmed both pathologically and immunohistochemically. US in the second group-patients treated with CO2 laser-detected at four patients 10 cervical lymph nodes that did not presented any malignant features. At recurrence alone, the US confirmed 100% presence of nodes metastases. Conclusions: US was superior to palpation and this method can be recommended as a diagnostic tool in preoperative assessment of patients without palpable metastasis (N0).

Anti-vascular endothelial growth factor (anti-VEGF) monoclonal antibodies can inhibit neovascularization and also to block the growth of several tumor cell lines. Treatment with anti-VEGF drugs like Bevacizumab (Avastin ® ) and Aflibercept has proven optimistic results in various malignant diseases. The present study was aimed to investigate Bevacizumab and Aflibercept in vitro effects on two human melanoma cell lines (A375 and SK-Mel-28), as well as on a healthy cell line (HaCaT human keratinocytes), followed by characterization of the in ovo effects on the chorioallantoic membrane (CAM). Our data indicated that Bevacizumab and Aflibercept decreased human melanoma cells viability in a dose-dependent way, a more significant effect was obtained for Aflibercept. Regarding the safety profile of the active compounds tested, they showed a low-moderate irritation score. In the case of the tested samples, the vascular capillaries were not majorly affected. In both cases, the only notable change was the appearance of a slight vascular coagulation. The viability of the embryos after application was good, they survived more than 24 hours after testing the compounds on the CAM.
