Histologically, it is recognized by clusters of CD30+ atypical lymphocytes in the background of mixed inflammatory infiltrate. It has been classified as type A, B, C, and D. Recently, a further variant of LyP was described as “angioinvasive LyP” in a series of 16 patients. We report a case of a 73-year-old female presenting with papules and nodules on the extremities evolving into eschar-like necrotic plaques. Histological examination revealed medium- to large-sized atypical lymphoid CD30+ cells densely infiltrating the dermis with distinct angioinvasion and angiodestruction. No systemic involvement was identified. The clinicopathologic features conformed to the newly described angioinvasive LyP.
