background : this study evaluates estrogen and progesterone expressions in patients with ovarian tumors (both benign and malignant) and their correlation with various clinicopathological prognostic parameters. receptors for estrogen and progesterone are predictive and prognostic markers of endometrial and breast cancers. however, their clinical significance in epithelial ovarian cancer is not c...

An 87 year-old white female presented with a two-year history of intermittent discomfort in her left foot. PET-CT identified intense18F-fluorodeoxyglucose (FDG) uptake corresponding to the lesion. Histology of a fine needle aspiration and open biopsy were consistent with a benign giant cell tumor (GCT) of the bone. GCT of bone is an uncommon primary tumor typically presenting as a benign solita...

Argon beam coagulation is becoming a user-friendly, safe adjuvant for treatment of benign aggressive bone tumors, despite little scientific literature available pertaining to the use of the device for bone tumors. It is becoming a part of the orthopaedic oncologist armamentarium used in treating bone tumors with a documented high rate of local recurrence. Our goal is to discuss the literature a...

Objective(s): This study aimed to evaluate the role of pretreatment SUVmax and volumetric FDG positron emission tomography (PET) parameters in the differentiation between benign and malignant mediastinal tumors. In addition, we investigated whether pretreatment SUVmax and volumetric FDG-PET parameters could distinguish thymomas from thymic carcinomas, and low-risk from high-risk thymomas.Method...

Submit Manuscript | http://medcraveonline.com benign bone tumors and %8-15 of all primary bone tumors. The World Health Organization describes the OC as a cartilage-capped bony protrusion on the external surface of bone [1]. Although Von Langenbeck defined coronoid process hyperplasia in 1853, Jacob first described OC of the coronoid process forming pseudojoint between the coronoid process and ...

Aneurysmal bone cyst (ABC) is a rare benign cystic lesion of the bone that composes 1-2% of the entire bone tumors. Some are idiopathic, and some occur secondary to other tumors such as giant cell tumor and chondroblastoma. In this article, we report the clinical, radiographic, and histological findings of a secondary ABC following chondroblastoma of the patella with a review of the literature.

Introduction: Different imaging modalities are used to evaluate salivary gland diseases, including tumors. Ultrasonography (US) is the preferred method on account of its ease of use, affordability, safety profile, and good tolerance among patients. The aim of this study was to evaluate the role of US in differentiating malignant from benign parotid tumors, in the context of previous controversy...

We present a case of spinal tumor, with fibrohistiocytoma combined with aneurysmal bone cyst (ABC) at the pedicle and transverse process of T7 in a 63-year-old female. ABC is a rare skeletal tumor and spinal ABC is extremely rare. Fibrohistiocytoma is a type of primary benign bone tumor. ABC is also a rare bone tumor that most often occurs in the pelvis. The combined lesion of two primary bone ...

INTRODUCTION Giant cell tumor of the bone is a relatively uncommon tumor. It is characterized by the presence of multinucleated giant cells. The tumor is usually regarded as benign. In most patients, giant cell tumors have an indolent course, but tumors recur locally in as many as 50% of cases. Metastasis to the lungs may occur. Cooper first reported giant cell tumors in the 18th century. In 19...

BACKGROUND Primary bone tumors remain a daunting challenge to orthopaedic surgeons. The challenge is heightened in developing countries due to limited diagnostic and therapeutic facilities and ignorance. The published literature on the subject is sparse in our environment. OBJECTIVE To describe the pattern of primary bone tumors seen in a tertiary hospital in Nigeria. METHODS This is a retr...
