Abstract Objectives The goal of the current study was to evaluate the relative frequency of oral and maxillofacial pathological lesions among Egyptian children. Materials and methods Records of biopsies submitted to the department of oral and maxillofacial pathology from the year 1999 to 2019 were retrieved and reassessed for all cases under the age of 18 years. Information on age, sex, location of the lesion, and the histopathologic diagnosis was analyzed. Results Over the course of twenty-one years, 1108 specimens were analyzed where reactive soft tissue lesions, which accounted for 397 (35.8%) of all cases ranked the highest presented category, followed by inflammatory odontogenic cysts, which accounted for 213 cases (19.2%). With 208 cases, the inflammatory radicular cyst was on the top of the most common 20 lesions, followed by pyogenic granuloma (160 cases). Malignancy was found in 19 cases, with soft tissue tumors (10 cases) being the most common, followed by salivary gland (5 cases) and bone pathologies (4 cases). Conclusions The frequency of oral and maxillofacial pathological lesions among Egyptian children increased over the years but remained consistent with global trends. Clinical relevance This is the first study evaluating the relative frequency of oral and maxillofacial pathological lesions among Egyptian children and provides an insight into the most commonly encountered pediatric pathologies. This may aid in the understanding of the most prevalent oral lesions that impact the pediatric population, as well as providing the key to early detection of lesions.

The Right

Abstract Lipoblastomas are rare soft tissue tumors that predominantly affect the pediatric population. We describe a lipoblastoma of the right hand in a 16-month-old boy. Radiographically the tumor appeared large but fairly well circumscribed and composed primarily of fat. Pathologic evaluation revealed variably sized lobules of adipose tissue and myxoid immature mesenchymal tissue separated by prominent fibrous trabeculae. Cytogenetic analysis showed a clonal chromosomal rearrangement with a breakpoint involving chromosome 8q11.2, confirming the diagnosis of lipoblastoma and thus helping to expand the clinicopathologic spectrum of tumors in this diagnostic category.

Gallium 67

The radionuclide gallium-67 (67Ga) localizes preferentially but not specifically in many human and experimental soft-tissue tumors. Because of this localization, 67Ga is used in clinical trials to detect humar. cancers by external scintiscanning methods. However, the fact that 67Ga does not localize specifically in tumors requires for its eventual clinical usefulness a fuller understanding of the mechanisms that control its deposition in both malignant and normal cells. We have previously reported that 67Ga localizes in lysosomal-like bodies, notably, although not exclusively, in macrophages of the spocytaneous AKR thymoma. Further studies on the uptake of 67Ga by macrophages are needed to determine whether there are factors related to malignancy that might alter the localization of 67Ga in these cells and thus provide clues to discovering the mechanism of 67Ga localization in tumor tissue.

Similar Accuracy

AbstractBone and soft tissue tumors are a largely heterogeneous group of tumors. Biopsy of musculoskeletal (MSK) tumors is sometimes a challenging procedure. Although the open biopsy is still considered the gold standard for the biopsy of MSK lesions, core needle biopsy can replace it in most cases, with similar accuracy and a low complication rate. The biopsy should be performed in a tertiary sarcoma center where the multidisciplinary team consists of at minimum a tumor surgeon, an MSK pathologist, and an MSK radiologist who can assess all steps of the procedure. Several factors can influence the success of the biopsy including the lesion characteristics, the equipment, and the method used for the procedure. This review highlights some of the important aspects regarding the biopsy of the MSK tumors, with special attention to imaging a guided core needle biopsy and highlighting some of the recent advancements and controversies in the field.

Response To Chemotherapy

: Differentiation of malignant from benign soft tissue tumors is challenging with imaging alone, including that by magnetic resonance imaging and computed tomography. However, the accuracy of this differentiation has increased owing to the development of novel imaging technology. Detailed patient history and physical examination remain essential for differentiation between benign and malignant soft tissue tumors. Moreover, measurement only of tumor size based on Response Evaluation Criteria In Solid Tumors criteria is insufficient for the evaluation of response to chemotherapy or radiotherapy. Change in metabolic activity measured by 18F-fluorodeoxyglucose positron emission tomography or dynamic contrast enhanced-derived quantitative endpoints can more accurately evaluate treatment response compared to change in tumor size. Magnetic resonance imaging can accurately evaluate essential factors in surgical planning such as vascular or bone invasion and “tail sign”. Thus, imaging plays a critical role in the diagnosis and treatment of soft tissue tumors.
