RESUMO

Nodal peripheral T-cell lymphoma (PTCL) with a T follicular helper phenotype (PTCL-TFH) is a new type of PTCL. We aimed to define its clinical characteristics and prognosis compared to PTCL not otherwise specified (PTCL-NOS) and angioimmunoblastic T-cell lymphoma (AITL). This retrospective observational study included 175 patients diagnosed with PTCL between 2008 and 2013 in 13 Spanish sites. Patient diagnosis was centrally reviewed, and patients were reclassified according to the World Health Organization (WHO) 2016 criteria: 21 patients as PTCL-NOS, 55 as AITL and 23 as PTCL-TFH. Median follow-up was 56.07 months (95% CI 38.7-73.4). Progression-free survival (PFS) and overall survival (OS) were significantly higher in patients with PTCL-TFH than in those with PTCL-NOS and AITL (PFS, 24.6 months vs. 4.6 and 7.8 months, respectively, p = 0.002; OS, 52.6 months vs. 10.0 and 19.3 months, respectively, p < 0.001). Histological diagnosis maintained an independent influence on both PFS (hazard ratio [HR] 4.1 vs. PTCL-NOS, p = 0.008; HR 2.6 vs. AITL, p = 0.047) and OS (HR 5.7 vs. PTCL-NOS, p = 0.004; HR 2.6 vs. AITL, p = 0.096), regardless of the International Prognostic Index. These results suggest that PTCL-TFH could have more favourable features and prognosis than the other PTCL subtypes, although larger series are needed to corroborate these findings.

RESUMO

Neurolymphomatosis is a rare disorder characterised by infiltration of neoplastic lymphocytes into the peripheral nervous system. A wide variety of symptoms can manifest depending on its nature and location, making its diagnosis a real challenge. Treatment is based on methotrexate, although various chemotherapy regimens are currently available for patients with systemic disease. We present the case of a male patient with neurolymphomatosis of the cauda equina, together with a review of all cases published to date.

RESUMO

OBJECTIVES: To report the 7th case of pararenal angiomyolipoma published in the world literature and to review the international bibliography. METHODS: We report the case of a 46-year-old female with history of renal colic and a complex mass on radiological tests. RESULTS/CONCLUSIONS: Extrarenal retroperitoneal angiomyolipoma is a rare pathology with no more than 7 published cases. The diagnostic difficulty and radiological similarities with liposarcoma make surgery the treatment of choice.
