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


Kempf, W; Keller, K; John, H; Dommann-Scherrer, C (2014). 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. American Journal of Clinical Pathology, 142(5):694-699.

Abstract

Objectives: Intravascular accumulations of atypical large lymphoid cells are a rare finding in skin biopsy specimens and raise the suspicion for intravascular lymphoma. The intravascular accumulation of atypical large CD30+ T cells, however, as a reactive process is very uncommon in the skin, with only four cases documented so far in the literature. This condition, referred to as benign intravascular atypical CD30+ T-cell proliferation, has been associated with chronic inflammation after trauma.
Methods: We report on a case of atypical intravascular CD30+ T-cell proliferation in a patient with ulcerated lichen sclerosus on the foreskin, discuss the differential diagnoses, propose diagnostic criteria, and review the literature on this uncommon reactive intralymphatic CD30+ T-cell lymphoproliferation.
Results: The atypical intravascular CD30+ T-cell proliferation is characterized by the accumulation of large CD30+ polyclonal T cells within lymphatics in close vicinity to ulceration or an inflammatory skin disease. There is no association with Epstein-Barr virus infection.
Conclusions: 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.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
