title: Benefits of skin biopsy of senile hemangioma in intravascular large B-cell lymphoma: A case report and review of the literature.
abstract: Intravascular large B-cell lymphoma (IVLBCL) is a rare subtype of B-cell lymphoma characterized by selective growth of clonal B-cells in the lumen of the small vessels of various organs including the liver, spleen, lungs, skin, brain, and kidney. An 86-year-old male presented with weight loss, fever and night sweats (known as B symptoms). Blood examination revealed pancytopenia, high lactate dehydrogenase and high soluble interleukin-2 receptor, suggesting hematopoietic malignancy. However, there were no abnormal hematopoietic cells in the peripheral blood. No lymph node swelling was identified on examination by whole-body computed tomography scan. Therefore, IVLBCL was suspected, and random skin biopsies and a skin biopsy from a senile hemangioma were carried out. A small number of large atypical lymphoid cells resided in the small blood vessels in the deep dermis and subcutaneous tissue of the random skin biopsies, and numerous atypical lymphoid cells were identified in the small vessels of the senile hemangioma. These results suggest the usefulness of skin biopsy from senile hemangiomas in the diagnosis of IVLBCL.
