Subcutaneous panniculitis-like T-cell lymphoma of the breast in an adolescent female: An Uncommon presentation

Abstract

Subcutaneous panniculitis-like T-cell lymphoma (SPTCL) is a rare form of peripheral T-cell lymphomas (PTCL) and is extremely uncommon in the pediatric population. We present a case of a 15-year-old girl with SPTCL and an unusual involvement of the breast. The FDG-PET/CT showed avid uptake of 18F-FDG in the breast predominantly involving the subcutaneous tissue that improves post treatment. To our knowledge, this is the first case of breast SPTCL reported in pediatric patient. A study published by Goto-et-al in 2019 [(1)](#ref-0001), found only 27 cases of SPTCL under 15 years, including four infants and none of them shown breast involvement.
