Subcutaneous panniculitis-like T-cell lymphoma (SPTCL) is an uncommon form of T-cell non-Hodgkin lymphoma in which cytotoxic CD8 (see 186910)+ T cells infiltrate adipose tissue forming subcutaneous nodules. Both children and adults can be affected, with a median age at diagnosis of 36 years and a female gender bias. Most patients have accompanying systemic features such as fever or flank pain. A subset (about 20%) of patients develop hemophagocytic lymphohistiocytosis (HLH), usually associated with CD8+ T cells rimming adipocytes in the bone marrow. An infectious agent is not identified, and the disorder is believed to result from improperly activated inflammation. Immunosuppressive therapy may be helpful; hematopoietic bone marrow transplantation is usually curative (summary by Gayden et al., 2018).
For a general discussion of genetic heterogeneity of HLH, see HLH1 (267700).
