background: neuroectodermal tumors (pnet) are malignant small cells neoplasm mainly occurring in children but can occur at any age. extensive bleeding into the pleural cavity is rare in children. hemothorax would be compatible with a variety of congenital anomalies including sequestration, patent ductus artreiosus, and pulmonary arteriovenous malformation. case report: a 2.5-years old girl who ...

Metastasis to the oral region is very rare and accounts for less than 1% of oral malignant tumors. Breast, lung, kidney, adrenal, gastro intestinal tract and prostates are most common primary tumors from which metastasis to oral region occur frequently. Metastasis from thyroid gland is extremely rare to oral region. We present an unusual case of metastatic follicular carcinoma of thyroid in max...

A spectrum of benign and malignant neural tumors can occur in oral and perioral region. The growth pattern and subsequent clinical behavior of the neurogenous tumors differs in different sites and pose significant diagnostic and therapeutic problems. This paper reviews the neural tumours of oral & paraoral region.

Primary malignant melanoma of the oral cavity is a rare neoplasm. The tumors tend to metastasize or locally invade tissue more readily than other malignant tumors in the oral region. The survival of patients with mucosal melanomas is less than for those with cutaneous melanomas. Tumor size and metastases are related to the prognosis of the disease. Early detection, therefore, is important.

Introduction: Oral tumors are one of the most challenging tumors regarding their good prognosis if diagnosed early and very difficult to control in advancing stages. Objectives: To study the prevalence, histopathological types and clinical presentation of various malignant oral tumors and their precursor lesions. Materials and Methods: This study includes the analysis of oral tumors received in...

Background: The oral cavity is one of the most common sites for various tumors and tumor like lesions. Among the malignant lesions, squamous cell carcinoma is single most common malignant lesion of this region. Aims and Objectives: To study the histopathology of different tumor and tumor like lesion of oral cavity with relation to age, sex , site and risk factors involved in these lesions. Mate...

BACKGROUND The purpose of this study was to assess and compare angiogenesis in ameloblastoma, keratocystic odontogenic tumors, dentigerous cysts, and normal oral mucosa. METHODS Angiogenesis was assessed in 28 ameloblastoma-36 keratocystic odontogenic tumors, 28 dentigerous cysts, and 19 normal oral mucosa by measuring the mean vascular density (MVD), total vascular area (TVA) and mean vascul...
