Practical Management of CD30⁺ Lymphoproliferative Disorders.

ABSTRACT

Primary cutaneous CD30⁺ lymphoproliferative disorders (LPDs) account for approximately 25% of cutaneous lymphomas. Although these LPDs are clinically heterogeneous, they can be indistinguishable histologically. Lymphomatoid papulosis rarely requires systemic treatment; however, multifocal primary cutaneous anaplastic large cell cutaneous lymphoma and large cell transformation of mycosis fungoides are typically treated systemically. As CD30⁺ LPDs are rare, there is little published evidence to support a specific treatment algorithm. Most studies are case reports, small case series, or retrospective reviews. This article discusses various treatment choices for each of the CD30⁺ disorders and offers practical pearls to aid in choosing an appropriate regimen.
