Generalized Telangiectasia as a Hallmark of Intravascular Lymphoma: A Case Report and Literature Review

Abstract

A 55-year-old woman had remarkably generalized telangiectasia. Large atypical lymphoid cells were found within the lumen of small vessels, and CD20 was positive in her third skin biopsy. She was diagnosed with intravascular large B-cell lymphoma (IVLBCL) and went into remission of the skin manifestations after seven courses of R-CHOP (rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisolone) and four courses of intravenous high-dose methotrexate (HD MTX). To our knowledge, this is the first case report of IVLBCL with generalized telangiectasia in China. From a review of the literature, we found that generalized telangiectasia is a remarkable manifestation of intravascular lymphoma, and the differential diagnosis of intravascular lymphoma and panniculitis or vasculitis is very important. When the diagnosis is confusing, multiple skin biopsies are useful.
