Subcutaneous panniculitis-like T cell lymphoma (SPTCL) is a rare cutaneous T cell malignancy of cytotoxic T cell origin. It is frequently associated with autoimmune diseases. It is known to preferentially involve subcutaneous adipose tissue and histologically resembles lupus panniculitis. The aetiology and risk factors of SPTCL are unclear and there are limited studies available since this entity was initially described in 2001. There are even fewer case reports describing the association between SPTCL and chronic lymphocytic leukemia (CLL). In this article, we present a case of SPTCL arising during treatment for CLL. We conducted an extensive review of literature to delve into the possible risk factors for SPTCL development in association with CLL, including pre-existing haematological malignancies, autoimmune conditions, immunomodulation and immunosuppressive chemotherapy.
