Primary cutaneous B-cell lymphomas— clinical and histopathologic features, differential diagnosis, and treatment
In this article, we discuss the clinical features, differential diagnoses, histopathologic features, and treatment options for each of the 4 types of CBCL. The proper categorization of these diseases can allow physicians to properly treat a patient with CBCL, including the avoidance of unnecessary therapy.

Histopathologic approach to epidermotropic lymphocytic infiltrates
Herein, we review the wide array of epidermotropic T-cell lymphomas and discuss distinguishing features between these entities. We also offer an algorithmic approach utilizing histopathologic, immunophenotypic, and molecular techniques that can be used for analyzing an epidermotropic T-cell infiltrate in order to render a specific diagnosis.

Approach to dermal-based lymphoid infiltrates and proliferations
In this review we advocate a stepped histopathological approach for dermalbased lymphoid infiltrations, employing as key elements the general lymphocytic composition (relative B- versus T-cell ratio), coupled with the predominant cytomorphology (cell size) present.
