It is rare for small lymphocytic B-cell malignancies to be associated with osteolytic bone lesions and/or hypercalcemia. The authors present an unusual case of well-differentiated lymphocytic lymphoma (DWDL) in a 70-year-old man who had osteolytic bone lesions and subsequently developed severe refractory hypercalcemia. The possible etiologic mechanisms responsible for these findings are discussed, and a brief review of the literature is presented.

Multiple myeloma (MM) is a hematologic disease characterized by the clonal expansion of malignant plasma cells that accumulate in the bone marrow, leading to osteolytic bone disease, hypercalcemia, anemia, and renal dysfunction. Daratumumab was the first monoclonal anti-CD38 antibody approved for the treatment of MM, initially in relapse/refractory settings and, more recently, for newly diagnosed patients. Increased first-line usage of daratumumab will also substantially change treatment approaches for patients with relapsed/refractory disease.

Background: Hybrid Odontogenic Tumors (HOT) are defined by the presence of two or more independent odontogenic tumors that originate from and affect the same maxillofacial site.
Methods: The present study is the first case report of a mandibular HOT consisting of Ameloblastoma, Calcifying Epithelial Odontogenic Tumor, and Ameloblastic Fibroma.
Case Report: A 37-year-old otherwise healthy male presented with the chief complaint of swelling in the right mandibular body.

Aneurysmal bone cysts (ABCs) are rare benign osteolytic tumors which occur most frequently within the first two decades of life and can lead to pathological fractures. They have characteristic imaging and histologic features and have historically been classified into two types: primary ABCs, which are true neoplasms linked to specific oncogenes, and secondary ABCs, which are preceded by other bone lesions. The occurrence of multiple concurrent primary ABCs is exceedingly rare; with only a few cases reported in the published literature.

Aneurysmal bone cysts (ABCs) are aggressive, osteolytic lesions usually seen in childhood and young adulthood. The patient's age, location, and behavior of the lesion in the bone may cause patients to present with different clinical findings. Appropriate treatment of these rare, aggressive bone lesions is essential for recurrence.
