Objectives The aim of the present study was to document the frequency and clinicopathologic features of intra-osseous jaw lesions in an Iranian pediatric population over a 20-year period. Methods Data were obtained from the archives of the Oral Pathology Department, Shahid Beheshti University of Medical Sciences, Tehran, Iran. The lesions were classified into four groups: (A) odontogenic cysts...

renal masses can be categorized as benign and malignant lesions. among the renal malignancies, renal cell carcinoma is the most common malignancy. however, other rare malignant lesions should be considered in differential diagnosis. primary renal lymphoma is quite rare and might be mistaken for renal cell carcinoma. due to lack of lymphatic tissue in the kidney, pathogenesis of renal lymphoma i...

Background: Abdominal cutaneous and subcutaneous nodules are uncommon benign or malignant lesions. The majority of the malignant nodules are metastatic in origin and may be the initial presentation of a primary malignancy; hence, an early diagnosis is important. Our aim of this study was to find out the spectrum of lesions (both non-neoplastic and neoplastic) that present as cutaneous and subcu...

To retrospectively review the causes of categorization errors using O-RADS-MRI score and to determine presumptive these misclassifications. EURAD database was queried identify misclassified lesions. In this cohort, 1194 evaluable patients with 1502 pelvic masses (277 malignant / 1225 benign lesions) underwent standardized MRI characterize adnexal histology or 2 years’ follow-up as a reference s...

many types of cancers develop in the oral and maxillofacial region. squamous cell carcinoma is the most common cancer and constitutes over 90 percent of these tumors. malignant transformation is a genetic process, which later makes a phenotyping change at the cellular level. some cancers such as oral squamous cell carcinomas (osccs) develop from pre-malignant lesions and conditions. despite adv...

Thirty cases of benign prostatic hyperplasia and 30 cases of prostatic adenocarcinoma were selected and stained by AgNOR (argyrophilic staining of the nucleolar organizer region) method. Specimens were obtained by either prostatectomy (open!TIJR) or needle biopsy of the prostate. In this study, the sections of prostatic adenocarcinoma were reviewed. 6 cases were diagnosed as well-differen...
