[New national treatment guidelines for primary cutaneous lymphoma].

Primary cutaneous lymphoma is a heterogeneous group of diseases where the malignant lymphocytes are primarily present in the skin at the time of diagnosis. The most common type of primary cutaneous lymphoma is mycosis fungoides. Early stages of mycosis fungoides present with flat or slightly elevated red skin lesions and can resemble eczema or psoriasis. In advanced stages erythrodermia or skin tumors can develop. For many patients with mycosis fungoides effective albeit not curative treatment is available. Large randomized treatment studies for mycosis fungoides are largely lacking, which makes decisions on treatment strategy difficult. The new national clinical guidelines will hopefully enable more equal care for patients with mycosis fungoides and other types of primary cutaneous lymphoma in Sweden.
