A General Approach to the Diagnosis of Cutaneous Lymphomas and Pseudolymphomas.

Both pathology and dermatology rely heavily on a visual approach to learning, generating differential diagnoses, and making diagnoses. Pattern recognition and the development of diagnostic frameworks are essential elements in this process. In addition to images, several algorithms and summaries are presented in this article to provide a practical approach to the diagnosis of cutaneous lymphoproliferative disorders. The critical importance of clinical pathologic correlation is also emphasized.
