[Lymphomas of the skin].
Malignant lymphoma of the skin is a type of extranodal lymphoma, in which the main organ involved is the skin, and 80-90% of cases in Japan show a T-cell phenotype. Mycosis fungoides (MF) and Sézary syndrome (SS) are common T-cell lymphomas of the skin with a benign prognosis. Therefore, various forms of topical therapy, such as topical steroid, photochemotherapy (PUVA) and interferons, have been indicated for the low-risk group (stages I A, I B and II A), whereas electron-beam irradiation, retinoid plus interferon (IFN), photopheresis and deoxycoformycin (DCF) plus IFN have been indicated for intermediate-risk group (stages II B and III). The cutaneous involvement of B-cell lymphoma has been considered an unmistakable sign of progression and dissemination of lymphoid disease, and is thus associated with a poor prognosis. However, some primary cutaneous B-cell lymphomas (CBCLs) show a benign prognosis, and electron-beam irradiation has been indicated for early-stage CBCL (stages I and II). However, the prognosis of high-risk group CTCL (stage IV) and cutaneous B-cell lymphoma (CBCL) (stages III and IV) is poor. Therefore, an effective multiagent combination chemotherapy, such as MACOP-B, M-BACOD or ProMACE-Cyta BOM is required for patients with advanced-stage CTCL and CBCL. With regard to age at the time of the first medical examination, patients with CTCL or CBCL at an advanced stage have a tendency to be older. Therefore, a mild but effective therapy, such as DCF plus IFN is recommendable.
