PURPOSE Bone scans showing solitary hot spots in the ribs pose diagnostic problems in patients with proved extraskeletal cancers. The authors wanted to determine the importance of solitary rib lesions and their correlation with other clinical manifestations. MATERIALS AND METHODS The study included 199 patients with solitary rib hot spots on their bone scans. The follow-up radiographic and sc...

We describe the first definitive case of a fibrous dysplastic neoplasm in a Neandertal rib (120.71) from the site of Krapina in present-day Croatia. The tumor predates other evidence for these kinds of tumor by well over 100,000 years. Tumors of any sort are a rare occurrence in recent archaeological periods or in living primates, but especially in the human fossil record. Several studies have ...

BACKGROUND Chest wall injury after stereotactic radiotherapy (SRT) for primary lung cancer has recently been reported. However, its detailed imaging findings are not clarified. So this study aimed to fully characterize the findings on computed tomography (CT), appearance time and frequency of chest wall injury after stereotactic radiotherapy (SRT) for primary lung cancer MATERIALS AND METHODS...

BACKGROUND Amplification and rearrangement of the epidermal growth factor receptor (EGFR) gene is frequently associated with malignant gliomas. One type of EGFR mutation in primary gliomas results in overexpression of an aberrant EGFR messenger RNA (mRNA) that lacks sequences of exons II through VI of the human EGFR gene. We observed that the aberrantly spliced EGFR mRNA contains a ribozyme cle...

BACKGROUND Radiation-induced rib fracture after stereotactic body radiotherapy (SBRT) for lung cancer has been recently reported. However, incidence of radiation-induced rib fracture after SBRT using moderate fraction sizes with a long-term follow-up time are not clarified. We examined incidence and risk factors of radiation-induced rib fracture after SBRT using moderate fraction sizes for the ...

Chondromyxoid fibroma (CMF) is a rare, benign cartilaginous tumor, comprising less than 1% of primary bone tumors, and usually occurs in the metaphysis of a long tubular bone around the knee. We report a rare case of CMF of the rib. The patient was a 25-year-old man who visited the hospital for left upper back pain. Roentgenography revealed an 8-cm mass in the left upper lung field; computed to...

A retrospective study of one decade of rib biopsy in four hospitals in Nashville, Tenn, showed 61 biopsies were done in 60 patients. The typical patient was a male in his seventh decade. Preferred operative technique was open biopsy with general anesthesia. One half of the patients had metastatic malignancy; most of the known primary tumors were lung cancer. About one fifth of specimens were no...

Method 220 patients from June 2002 to Dec 2014 were retrospectively analyzed. Patients of all ages, both sexes and operable primary chest wall tumor were included. Clinical evaluation, routine investigations, chest radiographs, computed tomography and biopsy were done. Incisional biopsy was done for >5 cm mass while excisional biopsy was done in smaller tumors. Complete excision of the chest wa...

Small cell osteosarcomas are very rare tumors which are classified as the component of Ewing's sarcoma family. Although the tumor generally is seen on long bones, short bone involvement is rare. Moreover, rib localization is quite uncommon and to the best of our knowledge, only one case has been reported so far. Herein, we described a case of rib-localized small cell osteosarcomas which was onl...
