Solitary bone cyst (SBC) is an uncommon, nonneoplastic osseous lesion that mainly affects metaphysis of long bones and rarely presents in jaws. Due to the lack of true epithelial lining, it is considered as a pseudocyst. It is generally asymptomatic and often discovered incidentally during routine radiographic examination as well-defined unilocular or multilocular radiolucent lesion in the posterior mandible mainly in the first two decades of life. Here, we report a very rare case of a 15-year-old female patient having a lesion in the posterior maxilla with clinical, radiological, and histopathological presentations of SBC.

Objective: To propose a revised bone reporting and data system (Bone-RADS) and evaluate its diagnostic performance and inter-reader reliability compared to the original Bone-RADS for solitary bone lesions on CT.
Materials And Methods: This retrospective study included 159 adult patients (mean age: 56 ± 19 years; 88 men) who underwent bone biopsy for solitary bone lesions between March 2005 and September 2021. Two radiologists (R1/2) independently categorized the lesions twice, once using the original Bone-RADS and once using the revised version.

Primary solitary extramedullary plasmacytoma is a malignant neoplasm characterized by the monoclonal proliferation of plasma cells outside the bone marrow. The tumor rarely occurs in the sinonasal tract, accounting for about 4% of all non-epithelial sinonasal tumors. Herein, the authors describe a rare case of sinonasal extramedullary plasmacytoma in a 33-year-old man who presented with a 3-month history of progressively increasing nasal mass, causing obstruction.

Extramedullary plasmacytomas (EMP) are uncommon solitary tumors composed of neoplastic plasma cells occurring outside the bone. These lesions are of clinical significance due to their potential progression to multiple myeloma (MM), a more systemic and serious plasma cell malignancy. Although EMPs primarily arise in the head and neck region, cases involving the oral cavity are particularly rare.

Introduction: Osteochondroma is a bony lesion arising from the surface of the bone. It com-prises a large percentage of all benign bone tumors. A unique feature of this tumor is the conti-nuity of cortical and medullary components between the normal bony tissue and aberrant tissue of osteochondroma.
