A rare case report of primary bone lymphoma and a brief review of the literature

A Case of Primary Sacral Lymphoma Evaluated by 18F-FDG PET/CT

Primary sacral lymphoma is an unusual bone malignant tumor that poses a diagnostic challenge. Herein, we report a rare case of primary sacral lymphoma, which was initially assessed as suspicious bone metastasis. The subsequent histology and immunohistochemistry of the sacral biopsy confirmed the diagnosis of diffuse large B-cell lymphoma.

Multiple osteolytic lesions due to Double-Expressor Primary non-Hodgkin Lymphoma of the Bone

Primary non-Hodgkin lymphoma of the bone (PLB) is a rare type of non-Hodgkin’s lymphoma (NHL) that affects the skeletal system with or without regional lymph node involvement. We present the case of a 74-year-old female patient with pain due to multifocal osteolytic lesions. The diagnosis of diffuse large B-cells (non-GCB) phenotype was made by clinical, laboratory, histopathological examination accompanied by an extensive immunohistochemical profile of one of the skeletal lesions.

Gastrointestinal tract metastasis of mandibular diffuse large B-cell lymphoma

Not only diffuse large B-cell lymphoma is a malignancy, but also is initially and orally diagnosed in early stages. However, it could be misdiagnosed with other oral pathologies. However yet, early diagnosis is still crucial for the prognosis, morbidity, and mortality in such cases. Additionally, whole-body scanning with positron emission tomography/computed tomography should be performed for diagnosis and treatment process.

A Rare Manifestation of Primary Bone Lymphoma: Solitary Diffuse Large B-Cell Lymphoma of the Little Finger

Solitary primary non-Hodgkin bone lymphoma of the hand is a rare entity with only 3 cases reported in the literature. We report the case of a 77-year-old patient with isolated large B-cell bone lymphoma of the proximal phalanx of the little finger without rheumatoid arthritis or methotrexate treatment. The patient was treated with digital amputation and at 6 months' follow-up showed no relapse or dissemination of the disease.

Classic Hodgkin lymphoma with osseous involvement mimicking Langerhans cell histiocytosis in a child

Hodgkin lymphoma (HL) commonly presents superficial lymphadenopathy. In addition, HL cells can arise in various organs including the liver and spleen as an extranodal lymphoma. HL in bone is unusual at the initial diagnosis, although some cases show late-stage localization of lymphoma cells to bone. We report the rare case of a young patient with cranial bone classic HL, presumably originating from the skull without any involvement of lymph nodes. As the main clinical manifestation was only tumor mass in the skull without osteoscopic pain, the tentative diagnosis of Langerhans cell histiocytosis was histologically confirmed by an excisional biopsy. Before the final pathological diagnosis as classic HL, we noticed several small lesions in extranodal regions through systemic surveys, suggesting that the cranial lesion appeared antecedent to those lesions. This is a rare and instructive case of cranial bone HL for which a histological diagnosis has been meticulously made.
