To be a “Lymphomatoid Papulosis Type E” or not to be? That Is a Question

Lymphomatoid papulosis (LyP) Type E is a recently introduced subtype of LyP presenting with escar-like lesions and characterized with angiocentric invasion of dermal blood vessels by CD30 positive atypical lymphocytes resulting necrosis of their walls. Owing to its considerable histologic characteristics such as dense dermal infiltration of CD30 positive large atypical lymphocytes showing high mitotic activity, and angiodestructive invasion, it is challengible to discriminate LyP Type E to aggressive cutanoues lymphomas.
