Twenty-four patients with chest wall tumors underwent resection during the past twenty years. There were 12 female and 12 male patients with ages ranging from 7 months to 78 years (mean 44 years). Five patients had primary malignant neoplasms, 7 had metastases, and 12 had benign tumors. The tumor was located in the soft tissue in 14 patients and in the ribs and the sternum in 10. Ninety-two per...

CONTEXT Since benign and malignant mucin-producing tumors of the pancreas may be difficult to distinguish from each other; preoperative methods for differential diagnosis would reduce unnecessary surgery. OBJECTIVE To compare syndecan-1 and tenascin immunoexpression in benign and malignant cystic pancreatic tumors. DESIGN We used immunohistochemical staining for syndecan-1 and tenascin anti...

CONTEXT Pancreatic dermoid cysts are rare, benign, germ cell tumors and part of the differential diagnosis for cystic neoplasms of the pancreas. CASE REPORT A 35-year-old man presented with an incidentally discovered, 2 cm cystic pancreatic neoplasm of the pancreatic tail identified on CT scan. Endoscopic ultrasound (EUS) revealed a complex, honeycomb lesion. Fine needle aspiration (FNA) yiel...

Introduction Meningiomas are the most common benign intracranial neoplasms. Extracranial metastasis from benign meningiomas is exceedingly rare and is seen in less than 0.1% to 0.2% of cases. Lungs (60%) and liver (34%) are the most common sites of extracranial metastasis. We describe a patient with delayed hepatic metastasis of a benign fibroblastic meningioma that was detected 31 years after ...

Introduction There are a variety of predictable circumstances in which benign lung lesions are at risk of being interpreted as malignant neoplastic processes. This brief overview will focus on three of them chosen because of their relative frequency in cases received for consultation. The most common diagnostic challenge is separating hyperplasia and/or metaplasia of non-neoplastic respiratory ...

Lipoma, a benign tumour of adipose tissue, is one of the most common benign neoplasms of the body. However, its occurrence in oral cavity is relatively rare. It accounts for 1 to 4% of benign neoplasms of the oral cavity, affecting predominantly buccal mucosa, floor of mouth and tongue. They have been known to grow to sufficiently large sizes causing problems in mastication and speech. The usua...

Background: Heparanase and endothelin-1/endothelin A receptor (ET-1/ETAR) expressions increase in cancer. This condition enhances tumor progression and correlates with poor survival. Limited data are documented regarding the role of heparanase and ET-1/ETAR in epithelial ovarian cancer (EOC). We sought to characterize the correlation between heparanase and ET-1/ETAR in EOC.Methods: Thirty patie...

BACKGROUND To determine the incidence and prevalence of salivary gland tumours in the province of Valparaíso, Chile. MATERIAL AND METHODS Retrospective review of salivary gland tumours diagnosed between the years 2000 and 2011 from four local pathology services. Information on demographics and histopathology were retrieved from the medical records. RESULTS The study sample consisted of 279 ...

Over the 8-year period 1971--1978, 743 benign lesions of the larynx, of which 551 were pseudotumors and 192 were benign neoplasms, were surgically treated at Groote Schuur Hospital. In comparison, during the same period 402 malignant tumours of the larynx were also seen. The commonest benign lesions were vocal cord nodules, almost exclusively found in women, and the vocal cord polyp, predominan...

Background: Soft tissue tumours are more diverse and heterogenous group of rare tumours. Sarcomas comprise <1% adult cancers which pose a great challenge in diagnosis treatment. The aim the study is to compare incidence evaluate type, sex predilection, anatomical location size all soft tumours.Methods: A prospective reported department Pathology, Thanjavur Medical College Hospital from July ...
