Cutaneous T-cell lymphoma (CTCL) has been described as a 'great mimicker'. The correct diagnosis hinges on effective collaboration between clinicians and pathologists to correlate pathological and clinical findings. The patient's history, lesion description and diagnostic work-up will help the pathologist interpret the histopathology, whilst the clinician’s diagnosis is aided by a clear understanding the terminology used in the pathology report. The treatment of early and advanced mycosis fungoides and its variants is potentially lifelong, with patients typically cycling among treatments, interspersed with periods of expectant therapy providing palliation and symptomatic relief. Effective management requires knowledge of the wide range of options, how they are used, and their side-effect profile, in order to tailor treatment to the individual patient. ' Fast Facts: Cutaneous T-Cell Lymphoma' is designed to help primary care providers, dermatologists, and oncologists to communicate effectively with pathologists in the diagnosis of this chronic condition, aided by over 100 superb clinical and pathological images, and to provide tailored long-term care for their patients. This concise, practical handbook will ensure clear communication with respect to the clinical presentation, histopathology, immunophenotyping and treatment of: • early and advanced mycosis fungoides and its variants • Sézary syndrome • other non-mycosis fungoides CTCLs. It is essential reading for pathologists, non-specialist clinicians and dermatology and oncology trainees.
