This book provides a current experience in the diagnostic techniques and treatment approaches available for unusual cutaneous lymphomas. It features concise case-based chapters with a particular emphasis on instances of mature T-cell and NK-cell neoplasms, mature B-cell neoplasms, immature hematopoietic malignancies, and other lymphoproliferative disorders. Clinically-oriented cases emphasize the importance of physical examination along with modern tests of laboratory diagnostics and clinico-pathological correlations.

Cutaneous Lymphomas: Unusual Cases 3 presents a range of difficult and rare cases, which would be uncommon even to the specialists in this field. Therefore, it is a vital reference source for dermatologists, dermatophatologists, cutaneous oncologists, hematooncologists, pathologists, oncologists, and other medical professionals who treat these patients.
