Differentiation between tumors and tumor-like lesions of the central nervous system is essential for planning adequate treatment and for estimating outcome and future prognosis. Neuroimaging fulfills an essential role in the correct differentiation between both entities. The radiologist should be aware of all non-neoplastic pathologies and diseases that may mimic tumors. High-end anatomic and f...

The clinical presentation of paracoccidioidomycosis is spectral. Spontaneous cure, state of latency or active disease with different levels of severity can occur after the hematogenous dissemination. The morphology and number of skin lesions will depend on the interaction of host immunity, which is specific and individual, and fungus virulence. Some individuals have natural good immunity, which...

Rhinosporidiosis is a granulomatous disorder caused by Rhinosporidium seeberi, an aquatic parasite. It spreads through contaminated water and soil. It frequently involves the nasal cavity and nasopharynx. Disseminated or systemic lesions are rare. A 56 year old man presented with multiple tumor like lesions all over the body in our cancer institute in April 2012. Fine needle aspiration cyto...

introduction: several treatment options have been introduced for removal of gingival hyperplasic lesions, but using diode lasers have many advantages such as less bleeding, time saving, better shaping, improved healing and less complication for the patients. case: a 15-year-old girl with multiple fibroma-like lesions in the oral cavity, who had a medical history of tuberous sclerosis, was selec...

Valvular tumor and tumor-like lesions are rare. Fibroelastoma is the most common valvular tumor, followed by myxoma. Atypical valvular lesions, such as organized thrombus, valvular calcification and valvular abscess may develop symptoms and present morphological features similar to those of the valvular tumors. The Author here reports a case of a tumour or tumourlike lesion over the mitral valv...

Cone beam computed tomography is a useful technique for imaging the craniofacial lesions. It produces more realistic images that facilitate interpretation. Juvenile ossifying fibroma (JOF) is a rare and benign fibro-osseous neoplasm that arises within the craniofacial bones, especially in the maxilla. Mandibular lesions can be seen in 10% of the cases.In both jaws, it has a predilection for the...

objective: the use of sugar-free chewing gums has been reported to be highly effective in the prevention of dental caries. this study carried out to compare the effect of mastic gum and a xylitol chewing gum on remineralization of caries-like lesions. materials and methods: in this cross-over, single blinded, in situ study, first, artificial caries-like lesions were created in six extracted hum...
