Methotrexate (MTX), an antimetabolite targeting certain autoimmune conditions and various hematologic malignancies, has been associated with iatrogenic lymphoproliferative disease (LPD) primarily of B-cell lineage.

A 9-month-old girl was evaluated for recurrent fevers, rash, and indurated plaques, with laboratories demonstrating hyperferritinemia, hypertriglyceridemia, and pancytopenia, concerning for hemophagocytic lymphohistiocytosis. Biopsy of thigh lesion ultimately demonstrated subcutaneous panniculitis-like T-cell lymphoma. In a rare neoplasm of cytotoxic T-cells, subcutaneous panniculitis-like T-cell lymphoma presents with subcutaneous nodules in all age groups including children.

Localized inflammatory reactions in patients with past procedural history of intradermal injections can quickly drive the clinician's attention towards a diagnosis of soft-tissue infection in the context of symptoms such as fever, malaise, and local induration of the adipose panniculus. However, in patients with a long-term history of granulomatous events, a rheumatologic approach must be taken into consideration when the clinical course overwhelms the odds for more conventional diagnoses. In this case, a 39-year-old female patient who underwent bilateral lower limbs intradermal filllers presented with a two-year clinical course of repetitive flares of external bilateral hip tenderness, pain that limits her walking, soft-tissue nodular inflammation, redness, fever and a soft mobile nonpainful right supraclavicular lymphadenopathy.

Introduction: Subcutaneous panniculitis-like T-cell lymphoma (SPTCL) is a rare subtype of non-Hodgkin lymphoma with a good prognosis, but the optimal treatment for relapsed/refractory (R/R) SPTCL has been rarely discussed.
Methods: This study aims to compare the efficacy of conventional chemotherapy and chemo-free immunomodulatory regimen for R/R SPTCL. We retrospectively reviewed the patients with first relapse or primary refractory SPTCL between September 1997 and October 2020.
