ABSTRACT
Lymphomatoid papulosis (LyP) is a relatively uncommon CD30+ lymphoproliferative disorder with a good prognosis. However, it is important to be cautious because 4%∼25% of the cases are accompanied by secondary lymphoma. LyP is divided into subtypes of infiltrate-descriptive categories based on the histological findings. Classically, LyP shows a patchy, wedge-shaped, dermal infiltrate of small to intermediate-sized lymphocytes, with atypical lymphoid cells and a variable mixture of neutrophils, histiocytes, and eosinophils. Follicular LyP (type F LyP), which was recently described and is not yet included as an official subtype in the World Health Organization classification, shares these characteristics, although its infiltrate is folliculocentric. Variable folliculotropism, follicular dilation, rupture, and mucinosis can occur. This entity is commonly misdiagnosed and is possibly underreported because its histopathologic features can masquerade as more common follicular-based entities. Herein, we report the case of follicular type LyP, which has not been reported in in Korean dermatology literature.
