Benign atypical intravascular CD30+ T-cell proliferation: a recently described reactive lymphoproliferative process and simulator of intravascular lymphoma: report of a case associated with lichen sclerosus and review of the literature.

摘要

This benign cutaneous lymphoproliferation needs to be distinguished from intravascular T-cell lymphoma, particularly from the intravascular variant of anaplastic large cell lymphoma. Obstruction of lymphatics due to lichen sclerosus with disrupted immune cell trafficking may result in the accumulation of activated CD30+ lymphocytes.
