Cutaneous lymphoma in Japan, 2012 –2017: A nationwide study

Non-Hodgkin lymphoma occurs at extranodal sites in approximately 27% of cases, with skin being the second most common site of extranodal involvement [1]. Cutaneous lymphomas (CLs) are divided into two categories as follows: CL in a narrow sense, so-called primary cutaneous lymphoma (PCL), and systemic lymphoma with skin involvement, known as secondary cutaneous lymphoma (SCL). Both PCL and SCL include a variety of subtypes. As PCL and SCL are rare disease entities, they are difficult to study on a large scale.
