INTRODUCTION: Delayed diagnosis of intravascular large B-cell lymphoma (IVLBCL) is associated with a poor prognosis, making early diagnosis and treatment essential. However, early diagnosis remains challenging.
CASE DESCRIPTION: Here we present the case of a 75-year-old man with fever of unknown origin, in whom random skin biopsy (RSB) allowed early diagnosis of IVLBCL.
DISCUSSION: The usefulness of RSB, which involves incisional skin biopsies of three or more sites that contain subcutaneous fatty tissue, such as the thighs, abdomen and upper arms, has been debated. In cases of suspected IVLBCL, RSB is less invasive than a biopsy of the internal organs.
CONCLUSION: We suggest that combining RSB with bone marrow examination may facilitate the diagnosis of IVLBCL.
LEARNING POINTS: Delayed diagnosis of intravascular large B-cell lymphoma (IVLBCL) is associated with a poor prognosis, but early diagnosis is difficult due to its diverse, non-specific presentation.This case report illustrates the value of random skin biopsy in the early diagnosis of IVLBCL in a man with fever of unknown origin and haematological abnormalities without lymphadenopathy, splenomegaly or bone marrow abnormalities.The diagnostic accuracy of random skin biopsy depends on several factors, including the location and number of sites biopsied, and the depth and width of the biopsy.
