Type D lymphomatoid papulosis

Definition: Three histological subtypes of lymphomatoid papulosis (LyP), type A (histiocytic), type B (mycosis fungoides like) and type C (anaplastic large cell lymphoma like) are well recognized. Two new histological variants, type D (simulating an aggressive epidermotropic cytotoxic lymphoma) and type E (angioinvasive type) has been also described.

Authors emphasize the indolent course of this entity although the histology would suggest a more aggressive disease.

Synopsis

- atypical dermal lymphoid infiltrate with epidermotropism
- immunohistochemical markers show a diffuse positivity for CD3 , CD8 , CD56 , T1A and granzyme B with the focal positivity of CD30.
