Abstract Background Head and neck melanoma (HNM) is specific from the anatomical etiopathogenetic aspects. In addition to morphopathological parameters, rich vascularization lymphatic drainage of head affect occurrence lymphogenic hematogenous metastases, as well metastases on both sides neck. Methods A retrospective cross-sectional study included cutaneous patients who underwent surgery at a clinical center over 10-year period. The follow-up was least 60 months.

Background and Objectives: Diabetic gastroenteropathy (DG) is a common complication of diabetes mellitus type 2. Interstitial cells are non-neural mesenchymal origin inserted between nerve elements smooth muscle cells, necessary for normal function peristaltic contractions in the gastrointestinal (GI) tract. There at least two types interstitial within GI layer-interstitial Cajal (ICC) platelet-derived growth factor receptor α-positive (IPC). The mechanism diabetic unclear, disorders caused...

Introduction. Metastatic melanoma of unknown primary (MMUP) is already a well described oncologic phenomenon in the literature, whereas tissue defects? reconstructions on neck region always present challenge for reconstructive surgeon. Two cases giant metastatic, skin infiltrative tumor masses are presented. In both MMUP was diagnosed. Both intraoperative defects were reconstructed using pectoralis major (PM) regional flap. Outline cases. The first patient admitted with mass right side neck....

Diabetic peristalsis disorders are common complications in diabetes mellitus type 2. Disturbance of interstitial cells Cajal (ICC) caused by metabolic changes could explain the symptoms diabetic gastroenteropathy. Although heterogenous cell types represent only 5% population muscle layer gastrointestinal tract (GIT), they important for conducting electrical signals and regulating excitability. The aim this study was to investigate alterations myenteric intramuscular ICCs gaster rats with 2...
