Unusual cutaneous lymphomas.
BACKGROUND
New variants of cutaneous lymphoma other than mycosis fungoides and Sezary syndrome continue to be described.


OBJECTIVE
A practical classification of cutaneous lymphomas is presented with detailed discussions of angiocentric T cell lymphoma, subcutaneous T cell lymphoma, and malignant angioendotheliomatosis.


METHODS
The recent pertinent medical literature relating to unusual cutaneous lymphomas is reviewed.


CONCLUSIONS
The utilization of immunohistochemistry in the dermatopathology laboratory has greatly enhanced the ability to recognize and categorize cutaneous lymphoma. Some illnesses previously believed to be non-neoplastic diseases are malignant lymphomas.
