In the WHO classification, subcutaneous panniculitis-like T-cell lymphoma (SPTL) is defined as a distinct type of T-cell lymphoma with an aggressive clinical behavior. Recent studies suggest that distinction should be made between SPTL with an alpha/beta T-cell phenotype (SPTL-AB) and SPTL with a gammadelta T-cell phenotype (SPTL-GD), but studies are limited. To better define their clinicopathologic features, immunophenotype, treatment, and survival, 63 SPTL-ABs and 20 SPTL-GDs were studied at a workshop of the EORTC Cutaneous Lymphoma Group. SPTL-ABs were generally confined to the subcutis, had a CD4-, CD8+, CD56-, betaF1+ phenotype, were uncommonly associated with a hemophagocytic syndrome (HPS; 17%), and had a favorable prognosis (5-year overall survival [OS]: 82%). SPTL-AB patients without HPS had a significantly better survival than patients with HPS (5-year OS: 91% vs 46%; P<.001). SPTL-GDs often showed (epi)dermal involvement and/or ulceration, a CD4-, CD8-, CD56+/-, betaF1- T-cell phenotype, and poor prognosis (5-year OS: 11%), irrespective of the presence of HPS or type of treatment. These results indicate that SPTL-AB and SPTL-GD are distinct entities, and justify that the term SPTL should further be used only for SPTL-AB. SPTL-ABs without associated HPS have an excellent prognosis, and multiagent chemotherapy as first choice of treatment should be questioned.

    • "Up until now, there has not been standard treatment established for SPTL due to its low incidence and lack of clinical trials. Anthracycline-based chemotherapy has been commonly used; however, the response rate is unsatisfactory [3]. Previous studies [5,7-14] demonstrated that 11 out of 14 SPTL cases were successfully treated with cyclosporine A, and 11 were induced to CR. "

    ABSTRACT: Subcutaneous panniculitis-like T cell lymphoma (SPTL) is a distinctive cutaneous lymphoma characterized by an infiltration of subcutaneous tissue by neoplastic T cells, similar to panniculitis. It is well-established that patients who are diagnosed with SPTL usually respond poorly to chemotherapy, showing fatal outcome. As a first line treatment for SPTL, anthracycline-based chemotherapy was most frequently used. For the treatment of SPTL, the efficacy of cyclosporine A has been recently reported in relapsed SPTL after anthracycline-based chemotherapy. However, it is still not clear whether cyclosporine A can be used as a first-line treatment against SPTL. Here, we report a case of SPTL, which achieved complete remission for nine years after first-line cyclosporine A therapy. This study suggests that cyclosporine A can induce a complete long-term remission as a first-line treatment.

    • "One patient presented the 1168C>T (Arg390stop) in a single allele and the other had two mutations, the 272C>T (A91V) and the 1262G>T (Phe 421Cys), in heterozygosity. Both patients suffered from HLH, a widely described phenomenon in both subcutaneous panniculitis αβ and γδ T-cell lymphomas [26]. "

    ABSTRACT: NK/T-cell lymphoma (NKTCL) is the most frequent EBV-related NK/T-cell disease. Its clinical manifestations overlap with those of familial haemophagocytic lymphohistiocytosis (FHLH). Since PERFORIN (PRF1) mutations are present in FHLH, we analysed its role in a series of 12 nasal and 12 extranasal-NKTCLs. 12.5% of the tumours and 25% of the nasal-origin cases had the well-known g.272C>T(p.Ala91Val) pathogenic SNP, which confers a poor prognosis. Two of these cases had a double-CD4/CD8-positive immunophenotype, although no correlation was found with perforin protein expression. p53 was overexpressed in 20% of the tumoral samples, 80% of which were of extranasal origin, while none showed PRF1 SNVs. These results suggest that nasal and extranasal NKTCLs have different biological backgrounds, although this requires validation.

    • "Marzano et al. [18] suggested that these conditions might span a clinical-pathological spectrum in which there is a natural progression from CHP to SPTL. Since the distinction of CHP from SPTL is difficult and CHP might be a precursor of SPTL [19], some authors proposed to use the term “panniculitis-like subcutaneous lymphoma with cytophagocytosis” instead of CHP, even when T-cell clonality was not documented [20]. This approach would have a beneficial effect on treatment planning towards oncological rather than anti-inflammatory therapy. "

    ABSTRACT: Cytophagic histiocytic panniculitis is a rare disease, associated with either nonmalignant conditions or subcutaneous panniculitis-like T-cell lymphoma, and often also associated with hemophagocytic lymphohistiocytosis (HLH). We report the case of a 11-year-old boy with a history of secondary HLH who, after a local trauma, developed a painful, indurated plaque over the right thigh associated with relapsing HLH. Histopathologic findings from skin biopsy specimens revealed significant lobular panniculitis with benign histiocytes showing hemophagocytosis. High-dose intravenous methylprednisolone and cyclosporine A treatment was highly effective. A genetic study after a new, relapsing episode of HLH revealed an heterozygous missense mutation on STX 11 gene inherited from the mother.
