lymphomatoid actinic keratosis
Friday 12 October 2012
The lymphomatoid actinic keratosis is mentioned here for completeness although it does not have epidermal atypia or lichenoid (interface) changes.
It is an epidermotropic subtype of cutaneous lymphoid hyperplasia with a dense, band-like infiltrate of lymphocytes beneath a sometimes hyperplastic epidermis.
It looks like a lichen planus-like keratosis but with epidermotropism rather than basal cell death.
