Abstract

Subcutaneous panniculitis-like T-cell lymphoma (SPTCL) is a rare subtype of cutaneous lymphoma. There have been a few case reports describing the radiologic imaging findings of SPTCL. We report a case of SPTCL, rarely presented with a breast mass. Here, we review her clinical history and radiologic (mammography and ultrasound) findings.

  Fig. 1 Subcutaneous panniculitis-like T-cell lymphoma of breast in 43-year-old woman. A. Mediolateral oblique mammographic view of left breast shows 5-cm, increased opacity with indistinct margin in upper portion of left breast. There are no calcifications or architectural distortion. Craniocaudal mammographic view of left breast shows no abnormal finding (not shown). B. Sonography of left breast shows diffuse hyperechogenicity with poorly defined margin in subcutaneous fat layer of left upper inner breast. C, D. Microscopic examination shows infiltration of neoplastic lymphoid cells into subcutaneous tissue (arrows), but not into overlying dermis and epidermis in low-power view (C, H&E staining, × 20) and focal rimming of adipocytes by atypical lymphocytes and phagocytic macrophages in subcutaneous tissue in high-power view (D, H&E staining, × 400). E. Immunohistochemical stain shows rimming of individual fat spaces by tumor cells with staining for CD8 (× 400).
