This atlas contains excellent clinical and histopathologic images and text of each of the types of cutaneous lymphoma (around 25 entities). It is the first go-to text for those who are considering a diagnosis of cutaneous lymphoma in their differential diagnosis. The text also includes diagnostic mimics of lymphoma and differential diagnosis tables and algorithms. The target audience is general practitioners, dermatologists, pathologists and students, residents and fellows. The diagnosis of lymphoma in the skin is confounded by the myriad of disorders that can mimic lymphoma clinically and histopathologically and by inconsistencies in the diagnostic classification that have only recently been resolved. In the last decade the European Organization for Research and Treatment of Cancer (EORTC) Cutaneous Lymphoma Group and the World Health Organization (WHO) Collaborated in a series of workshops and consensus meetings to arrive at a definitive classification scheme for cutaneous lymphoma. Unfortunately, the publication by the WHO that described this schema included all lymphomas and has the skin tumors scattered throughout the volume. There is currently no go to text for those who are considering a diagnosis of cutaneous lymphoma in their differential diagnosis. As a result there continues to be confusion about the diagnosis of cutaneous lymphoma, although this classification scheme was published in 2008.
