Аннотация
BACKGROUND: Lymphoblastic lymphoma (LBL) is a high grade, aggressive neoplasm, usually presenting in children and young adults. Precursor B-cell LBL is uncommon and may present with cutaneous or, less likely, bone lesions. This case represents the first reported presentation of LBL as a sacral lesion and was only the second fine needle aspiration biopsy (FNAB) of LBL presenting as a bony mass.
CASE: A 50-year-old man presented with a 3-month history of a 7 x 5 x 4-cm mass in the sacral region. The mass was radiologically described as an expansile one with lytic bone destruction. Diagnosis of a chordoma was radiologically favored. Computed tomography (CT)-guided FNAB, with flow cytometry and cytochemical staining, was used to make the diagnosis of precursor B-cell LBL.
CONCLUSION: FNAB was instrumental in reaching this unusual diagnosis in a patient who was free of disease after chemotherapy.
