OBJECTIVES Optical coherence tomography (OCT) is a high-resolution optical imaging technique that produces cross-sectional images of living tissues using light in a manner similar to ultrasound. This prospective study evaluated the ability of OCT to identify the characteristics of laryngeal cancer and measure changes in the basement membrane, tissue microstructure, and the transition zone at th...

conclusions small size, smooth lesion border and homogeneity favor benign nature of the incidental splenic lesions, while restricted diffusion might be a feature of malignancy. follow-up imaging might be helpful in a subset of patients to discriminate benign and malignant incidental splenic lesions. methods this retrospective study was performed in a tertiary referral center. data of patients w...

UNLABELLED Forceps biopsies of airway lesions have variable yields. The yield increases when combining techniques in order to collect more material. With the use of cryotherapy probes (cryobiopsy) larger specimens can be obtained, resulting in an increase in the diagnostic yield. However, the utility and safety of cryobiopsy with all types of lesions, including flat mucosal lesions, is not esta...

Sebaceoma is a benign tumor with sebaceous differentiation. It usually presents as a yellowish papule or nodule on the face and scalp. This is a report of a 27-year-old-woman who presented with a giant, 6cm×4.5 cm exophytic tumor on her head. Clinically, we considered several diseases; however, the histological and immunohistochemical features matched those of sebaceoma. The lesion was excised ...

in 30 patient with single cold thyroid nodule and normal thyroid function tests, 99mtc-mibi scan is performed. the nodules are divided to hot (10), warm (12) and cold (8). fna reported papillary ca in 4, suspicious follicular neoplasm in 3 and 23 benign lesions. 7 patients were operated on and had final pathology reports (4 papillary ca and 3 benign lesions). all the nodules with no mibi uptake...

Chondroblastoma is a benign epiphyseal chondromatous lesion typically seen as small, well-defined, eccentric with thin rim of surrounding bone sclerosis. Soft tissue extension, metaphyseal involvement, periosteal reaction, cortex breach though not pathognomonic, are reported in literature. We present case report patient chondroblastoma showing atypical radiological presentation exophytic mass o...

Background Radiation-induced osteosarcomas of the jaws are a rare but often fatal consequence radiation therapy in head and neck region. Here we present case radiation-induced osteosarcoma mandible. Case Presentation A male presented with severe trismus marked left lingual alveolus expansion 1 year following extractions lower quadrant. Four years previously, he had radical radiotherapy (70Gy) c...

We have analyzed the association between host hormonal status and growth rate of congenital exophytic melanomas of Sinclair swine. The growth of multiple exophytic lesions during the first year of life of intact males, orchiectomized males, intact females, and ovariectomized females was quantitated using a proliferative index which assigned a numerical value to fixed increments of gains or loss...

In 30 patient with single cold thyroid nodule and normal thyroid function tests, 99mTc-MIBI scan is performed. The nodules are divided to hot (10), Warm (12) and cold (8). FNA reported papillary Ca in 4, suspicious follicular neoplasm in 3 and 23 benign lesions. 7 patients were operated on and had final pathology reports (4 papillary Ca and 3 benign lesions). All the nodules with no MIBI ...
