Bilineal T lymphoblastic and myeloid blast transformation in chronic myeloid leukemia with TP53 mutation-an uncommon presentation in adults

T cell acute lymphoblastic lymphoma complicated with myeloid sarcoma in an adult: A case report

The present case report describes a rare case of T cell acute lymphoblastic lymphoma (T-LBL) in the lymph node with myeloid sarcoma in the pericardium. A 33-year-old Chinese male was admitted to hospital on 4 July 2015 exhibiting a fever and having experienced wheezing and fatigue for the previous 7 days. Routine pathological, computed tomographic, cytological and immunophenotypic observations revealed a diagnosis of T-LBL in the lymph node on 7 August 2015, without evidence of bone marrow (BM) involvement. The patient received induction chemotherapy for T-LBL and achieved partial remission. The patient was identified to have multiple serous effusion and analysis of pericardial effusion cells revealed the diagnosis of T-LBL with extramedullary myeloid sarcoma (without BM involvement) on 25 November 2015. On 30 December 2015, the patient was identified to exhibit proliferation of primary myeloid cells in the peripheral blood and BM, and an abnormal karyotype in BM cells, indicating that the complicated myeloid sarcoma involved the BM. No matched donor was available so the patient received chemotherapy to manage the disease. The patient was discharged on 31 January 2016 and ceased treatment. The patient succumbed on 19 February 2016 at home. To the best of our knowledge, T-LBL complicated with myeloid sarcoma had not been previously reported in Chinese adult male patients. In addition, the involvement of the BM and aberrant karyotype of the complicated myeloid sarcoma in the patient were rare.

Philadelphia chromosome-negative non-Hodgkin's lymphoma occurring in Philadelphia chromosome-positive chronic myeloid leukemia: A case report and literature review

The current study reports the case of a patient with Philadelphia chromosome-negative (Ph^-) non-Hodgkin's lymphoma (NHL) and chronic phase (CP) Philadelphia chromosome-positive (Ph⁺) chronic myeloid leukemia (CML) that also possessed characteristic enlarged lymph nodes. A lymph node biopsy resulted in the diagnosis of CP-CML, in addition to T-lymphoblastic cell NHL with negative break point cluster/Abelson tyrosine kinase fusion genes in the lymph node of the patient, which was diagnosed as Ph^- NHL. A review of the literature was performed in the present study to investigate the genetic differences between Ph^- NHL and Ph⁺ NHL in patients with CML. The median age of patients with NHL and CML was 41 years. The follow-up time of patients with Ph⁺ NHL was significantly shorter (mean, <6 months) compared to the follow-up time of patients with Ph^- NHL (mean, >15 months). Therefore the present study concludes that Ph⁺ NHL may be more aggressive compared with Ph⁺ NHL. The present study suggests that additional studies are required to assess the clinical and genetic characteristics of NHL patients with CML.
