conclusions results of the present study showed that hydroalcoholic extracts of pomegranate seeds had a significant protective effect against bleomycin-induced lung fibrosis by its antioxidant properties. the highest protective effect was observed for the 400 mg/kg dose. results histological analysis showed that pse could prevent pathological changes that were seen in the bleomycin group. objec...

there are many studies about epidural fibrosis after surgical manipulation of the spine. we have studied formation of the post laminectomy epidural fibrosis after application of two materials (silicone and teflon) in this report. this expriment is on two groups of rats. two separated laminectomies were done in each rat, one serving as control while in the other laminectomy spaces silicone was u...

Nodular fasciitis is a benign proliferation of myofibroblasts which presents clinically as a rapidly growing mass with nonspecific features on imaging and high cellular activity on histopathology. Nodular fasciitis can be mistaken for malignant fibrous lesions such as soft tissue sarcoma or breast carcinoma when located within breast tissue. This presents a problem for appropriate treatment pla...

Nodular lung disease is a rare pulmonary manifestation of sarcoidosis and resembles metastatic neoplasm disease. Nodular sarcoidosis is rare, varying from 1.6% to 4% of patients with sarcoidosis. Radiographic nodules measure from 1 to 5 cm in diameter that typically consist of coalescent granulomas. There is limited data on this form of sarcoidosis and its presentation can mimic primary or meta...

BACKGROUND To date, appropriate management for Bethesda IV thyroid nodules is controversial, and no specific features of follicular neoplasm and nodular hyperplasia on ultrasonography, computed tomography (CT), or other imaging modalities have been reported. This study aimed to compare CT features of follicular neoplasm and nodular hyperplasia and to determine the specific CT features that coul...

A case of nodular fasciitis occurring at the bladder vertex in a 34-year-old male is reported. The tumor was about 1 cm in diameter. A urachal tumor was diagnosed, and excised en bloc from the umbilicus to the bladder vertex. This tumor was diagnosed as nodular fasciitis from the histopathological findings. No recurrence has been seen for 3 years. Nodular fasciitis occurs mainly in the limbs or...

While regression of focal nodular hyperplasia of the liver is not uncommon, reports of near-complete involution or regression of these lesions are rare. We report two cases of focal nodular hyperplasia that underwent near-complete regression-one in a 27-year-old female that regressed over a period of 4 years, and one in a 46-year-old female that regressed over a 7-year period. Both patients dis...

Focal nodular hyperplasia and nodular regenerative hyperplasia are occasionally seen in patients with hepatic venous outflow obstruction as a consequence of circulatory stress in the liver. In addition, neoplastic processes such as hepatic adenoma, hepatocellular carcinoma, and metastatic disease may arise in these patients. Histologic evaluation is necessary when imaging modalities are unable ...

Nodular fasciitis is a rare benign lesion. Here we report a case of post-auricular nodular fasciitis, which was misdiagnosed by fine-needle aspiration cytology (FNAC) as pleomorphic adenoma. An 18-year-old male presented at Al-Nahdha Hospital, physical examination revealed a right post aural firm immobile mass. Radiology suggested the presence of a hypo-dense to iso-dense subcutaneous mass. The...
