Subcutaneous panniculitis-like T-cell lymphoma (SPTCL) with probable mesentery involvement with associated hemophagocytic syndrome (HPS) - how to treat it?

Subcutaneous panniculitis-like T-cell lymphoma (SPTL) is a rare, cutaneous lymphoma involving subcutaneous adipose tissue. SPTL is associated in less than 20% with hemophagocytic syndrome (HPS). A 5-year overall survival rate is inferior in pts with SPTLand HPS (46%) as compared with 91% in pts without HPS. No standardized therapy for SPTCL has yet been established. A case of 35-year-old Caucasian man with a one-month history of B symptoms with the suspicion of Still's disease. At admission with leucopenia, high LDH, ferritin, sIl-R2, and triglycerides levels, hepatosplenomegaly, small right supraclavicular nodule, and irregular thickening of trunk subcutaneous tissue. The abdomen MRI showed generalized thickening of mesentery and colonic mucosa. In the patient diagnosis of SPTCL was established with secondary HPS. CHOEP chemotherapy and modified HLH 2014 protocol were applied with subsequent high dose chemotherapy (BEAM) supported by autologous stem cells transplantation. Treatment was complicated by pancytopenia and pneumonia. The outcome of the disease treated by intensive protocol seems to be good.
