Subcutaneous Panniculitis-Like T-Cell Lymphoma of the Breast

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.

Usefulness of high‐frequency ultrasonography in the assessment of cutaneous lesions in children with hematologic malignancies

“…The lack of high blood flow in Doppler mode noted in our patient is consistent with the literature; only half of cutaneous lymphoma Doppler images show profuse intralesional vascularity . In addition, cases of panniculitis‐like T‐cell lymphoma and extranodal natural killer cell/T‐cell lymphoma have produced images that resemble cutaneous panniculitis …”

“…The lack of high blood flow in Doppler mode noted in our patient is consistent with the literature; only half of cutaneous lymphoma Doppler images show profuse intralesional vascularity 9,11. In addition, cases of panniculitis-like T-cell lymphoma and extranodal natural killer cell/T-cell lymphoma have produced images that resemble cutaneous panniculitis 8,11. B-cell lymphoblastic lymphoma arising from B-cell precursors is a rare hematologic neoplasm that can manifest as a nodule on the head and neck,[12][13][14] primarily or as part of systemic disease.…”

“…Few reports on the use of ultrasound in cutaneous lymphoma have been published, with most images obtained using 10‐ to 18‐MHz probes . A diffuse pattern has been associated with primary cutaneous T‐cell lymphomas, in which ill‐defined, nonhomogenous dermal thickening can extend to the hypodermis .…”

“…Intralesional or peripheral and multifocal vascularity is also more likely to appear in malignant lesions, whereas avascularity or peripheral monofocal vascularity are more frequently found in benign tumors 3. Few reports on the use of ultrasound in cutaneous lymphoma have been published, with most images obtained using 10-to 18-MHz probes [5][6][7][8][9]. A diffuse pattern has been associated with primary cutaneous T-cell lymphomas, in which ill-defined, nonhomogenous dermal thickening can extend to the hypodermis 5.…”

T-Cell Non-Hodgkin Lymphomas: Spectrum of Disease and the Role of Imaging in the Management of Common Subtypes

“…Patients with SPTCL typically present with one or more usually painless nodules or poorly circumscribed indurated plaques most commonly located on the trunk or lower extremities (5758). Initial diagnosis of SPTCL is often delayed because inflammatory or infectious processes may be suspected both clinically and on imaging.…”
