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.
皮下脂膜炎样T细胞淋巴瘤（SPTCL）是皮肤淋巴瘤的一种罕见亚型，临床上表现为红斑、皮下浸润及反复出现的丘疹结节。在2005年世界卫生组织-欧洲癌症研究与治疗组织皮肤淋巴瘤分类中，它被定义为一种罕见的细胞毒性α/β T细胞淋巴瘤，其特征为主要累及模仿脂膜炎的皮下组织，且具有占主导的CD3+/CD4/CD8+表型。在代谢成像上，这些病变总是摄取氟脱氧葡萄糖（FDG）。表现为乳腺肿块的SPTCL是一种罕见情况。在此，我们报告一例表现为FDG摄取的乳腺肿块及皮下结节的SPTCL病例。
