[WHO classification and clinical spectrum of cutaneous lymphomas].

BACKGROUND

Cutaneous lymphomas are rare skin cancers with a wide clinical spectrum.

OBJECTIVE

To give an overview of the current classification and the clinical spectrum of cutaneous lymphomas.

MATERIAL AND

METHODS

Analysis and summary of the current literature concerning the different entities of cutaneous lymphomas.

RESULTS

A few modifications in the nomenclature of cutaneous lymphoma have been introduced in the revised version of the WHO classification 2016. In the last years new types of lymphomatoid papulosis were described. Moreover, two subgroups of folliculotropic mycosis fungoides are now mentioned. The CD4+ small/medium T‑cell lymphoproliferative disorder is no longer classified as an overt lymphoma. As new entities the EBV+ mucocutaneous ulcer, an EBV-associated diffuse large B‑cell lymphoma (not otherwise specified) and a primary cutaneous acral CD8+ T‑cell (provisional) lymphoma are being considered.

CONCLUSION

The classification of cutaneous lymphomas is based on the revised version of the WHO classification (2016). The clinical pathological correlation is an elementary component for correct diagnosis.
