The efficacy of photodynamic therapy (PDT) depends upon the delivery of both photosensitizing drug and oxygen. In this study, we hypothesized that local vascular microenvironment is a determinant of tumor response to PDT. Tumor vascularization and its basement membrane (collagen) were studied as a function of supplementation with basement membrane matrix (Matrigel) at the time of tumor cell ino...
Basal cell carcinoma (BCC) commonly affects the elderly and is mostly confined to the head and neck region. Only 10% of all cases occur on the trunk. We presented a case of bullous lesion on the abdomen in a young male, initially diagnosed by clinicians as a vascular nevus. Histopathological examination and immunohistochemistry (IHC) revealed it to be Nodular cystic variant of BCC. This rare va...
Tubulin-binding vascular-disrupting agents (VDA) are currently in clinical trials for cancer therapy but the factors that influence tumor susceptibility to these agents are poorly understood. We evaluated the consequences of modifying tumor vascular morphology and function on vascular and therapeutic response to combretastatin-A4 3-O-phosphate (CA-4-P), which was chosen as a model VDA. Mouse fi...
There are few reported cases of endobronchial metastasis of pheochromocytoma literature. We present here a 56-year old woman who underwent left lower lobectomy of lung, following pneumonia with unresolved chest radiographs. Computed tomography showed a lobulated soft tissue mass, measuring, 38×27 mm, at the perivascular space of anterior mediastinum. The resected specimen, showed lobulated tumo...
AIMS Vascular invasion by tumor cells is known to be important for cancer progression. By microarray and qPCR analyses, we earlier identified an 18-gene signature associated with vascular involvement in endometrial cancer. Here, we explored the significance of this vascular invasion signature in multiple series of breast cancer patients. METHODS AND RESULTS The study includes 11 open access g...
Haemangioma is a benign tumor of vascular endothelial cells or their progenitors. In spring of 2016, an Acipenser baerii, (+3 years, 2.2 kg weight) was reffered to the Department of Aquatic Animal Health, Faculty of Veterinary Medicine, Shahid Chamran University of Ahvaz. After dissection it was found that the heart had a cobblestone appearance which was characterized by multiple dark red cysts...
Introduction: Solid and cystic papillary epithelial neoplasm of pancreas is a rare neoplasm with low malignant potential which often occurs in young women. The tumor is usually large and encapsulated. Microscopic examination reveals small round cells with papillary-configuration in a delicate vascular stroma. Case Report: The cases presented in this report were 2 women at the age of 15 & 26...
