Abstract

Subcutaneous panniculitis-like T-cell lymphoma (SPTCL) is an unusual subtype of cutaneous lymphoma and clinically appears as erythematous, subcutaneous infiltrates, and recurrent papulonodules. It is deﬁned as a rare cytotoxic a/b T-cell lymphoma characterized by primary involvement of subcutaneous tissue-mimicking panniculitis and a predominant CD3+/CD4/CD8+ phenotype in (2005) the World Health Organization-European Organization for Research and Treatment of Cancer classiﬁcation for cutaneous lymphomas. On metabolic imaging, these lesions are invariably fluorodeoxyglucose (FDG) avid. SPTCL which presents as a breast mass is a rare entity. Here, we present a case of SPTCL presents as FDG avid breast mass and subcutaneous nodules.

Keywords: Breast mass; fluorodeoxyglucose positron emission tomography/computed tomography; subcutaneous panniculitis-like T-cell lymphoma.
