Background: Neonatal tumors are usually prenatally diagnosed or within the irst 30 days of life. The true incidence ofneonatal tumors is unknown as a great number of pregnancies with a prenatally diagnosed mass result in stillbirth ormiscarriage. Most solid neonatal tumors are benign whereas less than 50% of neonatal neoplasms are malignant;however, some tumors with malignant ...

breast cancer is common and is considered second cause of cancer related mortality in females. regarding importance of breast cancer, more investigation in this field is recommended. for many years investigators believed that neoplasms were not innervated but new findings have proved otherwise. this descriptive study was carried out to compare number of nerve fibers in benign, malignant and nor...

Of 291 juvenile and adult snakes examined post mortem over a 20-year period (1978-1997) at the National Zoological Park (NZP) in Washington, DC, 36 (24 females and 12 males) had neoplasms. Two snakes had tumours of two or three different types, but the other 34 snakes had only one type. All affected animals were adults and their average time on exhibit at the NZP was 108-9 months. Malignant neo...

Primary neoplasms of the pleura are rare tumors and the majority are generally mesotheliomas. Mesotheliomas are either localized and mostly benign, or diffuse and uniformly malignant neoplasms. Localised benign pulmonary mesothelioma (solitary fibrous tumor of the pleura) are originally thought to be a variant of diffuse pleural mesothelioma because they consists of a spindle cell stroma associ...

The grass carp (Ctenopharyngodon idella) is a herbivorous, freshwater fish species of the family Cyprinidae, and the only species of the genus Ctenopharyngodon. Neoplasms in fishes are generally less aggressive than neoplasms in mammals and are most commonly discrete, focal and benign neoplasms. A 3-year-old grass carp with a big mass on the vertebrae was referred to the clinic...

INTRODUCTION Ovarian cancer has a high mortality and delayed diagnosis. Inflammation is a risk factor for ovarian cancer, and the inflammatory response is involved in almost all stages of tumor development. Immunohistochemical staining in stroma and epithelium of a panel of cytokines in benign and malignant ovarian neoplasm was evaluated. In addition, immunostaining was related to prognostic fa...

Background and objective: Fine needle aspiration cytology (FNAC) of salivary gland lesions is an accepted and useful diagnostic tool to differentiate between benign and malignant lesions. Majority of the neoplasms are benign, and specific diagnosis on cytology can be made in most of the cases. However, the utility is limited by the overlapping and heterogeneous morphol...

BACKGROUND: Sebaceous lymphadenoma is a rare benign salivary gland tumour of uncertain histogenesis. So is synchronous occurrence of two benign or malignant neoplasms. CASE-REPORT: 68-year-old female presented with right side parotid swelling associated with pain and gradual increase is size. Fine needle aspiration cytology of parotid swelling was suggestive of pleomorphic adenoma. Total conser...

Despite of the fact that the vulva contains a high density of apocrine and anogenital mammary glands in addition to eccrine glands and folliculosebaceous units, the benign vulvar adnexal tumours are rare. Though the varied clinical presentation and diverse histopathological spectrum of vulvar neoplasms has amazed the pathologists, only few studies have been reported in literature. The present f...
