A Rare Case of Adrenal Intravascular Large B-Cell Lymphoma Diagnosed via Percutaneous Needle Biopsy

IVLBCL is often overlooked due to its varied and nonspecific clinical presentation, making early diagnosis difficult. The disease progresses rapidly and has a poor prognosis, with definitive diagnosis relying on pathological findings. Increased awareness of this rare lymphoma is crucial, particularly for diagnosing needle biopsy specimens in patients with mild symptoms and no distinct space-occupying lesions. Careful morphological examination, supported by targeted immunohistochemical staining (for B-cell and endothelial markers), is essential for timely diagnosis.
