Recent trends of incidence and mortality of cutaneous lymphomas in Germany. [PDF]
J Dtsch Dermatol GesSummary Background Primary cutaneous lymphomas (PCL) are primarily composed of cutaneous T‐cell lymphomas (CTCL), followed by cutaneous B‐cell lymphomas (CBCL). This study aimed to assess the incidence and survival rates of PCL in Germany. Methods We analyzed data from the North Rhine‐Westphalia Cancer Registry (2008–2021), which covers a population of
