Most pleural neoplasms are metastatic in origin. Primary tumours of the pleura are rare and categorized as diffuse or localized. Diffuse or malignant mesothelioma is more common, related to asbestos exposure, and associated with a poor prognosis. Localized or solitary fibrous tumour (SFT), of the pleura is a less common neoplasm of controversial histogenesis and is unrelated to asbestos exposur...

Problem statement: Elastography is developed as a quantitative approach to imaging linear elastic properties of tissues to detect suspicious tumors. We propose an automatic feature extraction method in ultrasound elastography and echography for characterization of breast lesions. Approach: The proposed algorithm was tested on 40 pairs of biopsy proven ultrasound elastography and echography imag...

This chapter presents a bibliographic review of asbestos-related diseases. The latest diagnostic, radiological, computed tomography and lung function aspects of benign pleural disease, asbestosis, occupational lung cancer and mesothelioma are discussed.

Benign cystic teratoma is recognized as one of the most common tumors in women during the reproductive age and frequently is treated by pelviscopic operation. Malignant transformation of a benign cystic teratoma is a rare event, and adenocarcinoma is extremely rare, and distinguishing this malignant change from benign disease preoperatively is nearly impossible even by the use of radiological i...

cystic lymphangioma is a rare benign tumour occurring during childhood. this tumour, caused by lymphatic system malformations, commonly occurs in head and neck regions. herein, we report the case of a three-month-old male infant, diagnosed with a large cystic mass in the abdominal cavity and groin. the infant presented with low-grade fever and significant abdominal distension. abdominal ct scan...

Surgical excision has traditionally been the treatment of choice for benign non-thyroid cystic neck masses, including lymphatic malformation, ranula, branchial cleft cyst, thyroglossal duct cyst, and parathyroid cyst. However, there is a tendency toward recurrence after surgery, and surgery may be accompanied by complications, including nerve injuries, vascular injuries, and scar formation. Ult...

cystadenoma is a rare benign salivary gland tumor that chiefly originates in the minor salivary glands as a cystic growth with papillary projections into the cystic lumen without the lymphoid element. it is further classified into two histopathological variants that have been recognized by world health organization as the papillary and the mucinous forms of cystadenoma. clinically, it is diffic...

In 2005 we reported in this journal the treatment of cystic nephroma, a rare but presumed benign renal tumor, with percutaneous resection. Initial follow-up confirmed removal of the intra-pelvic portion of the cystic nephroma and persistence of the unresected intra-parenchymal portion. Surveillance with computed tomography revealed gradual regrowth of the mass, ultimately resulting in a size gr...

We herein report the clinicopathologic features of a rare case of biliary adenofibroma (BAF) of the liver in a 79-year-old man. Grossly, tumour presented as a well-circumscribed, 5.5-cm mass with a solid and microcystic appearance. Histological examination was typical of biliary adenofibroma, showing a proliferation of variable-sized tubulocystic structures embedded in a moderately cellular fib...
