A case of late-onset sinusoidal obstruction syndrome diagnosed histologically before meeting diagnostic criteria.

Sinusoidal obstruction syndrome (SOS), also known as hepatic veno-occlusive disease (VOD), is a life-threatening complication of hematopoietic stem cell transplantation. In severe cases, SOS/VOD progresses to multiple organ failure with a mortality rate higher than 80%. Early diagnosis and treatment based on severity assessment improve the prognosis of severe SOS/VOD, but conventional diagnostic criteria may be insufficient for an early diagnosis.

[Peripheral T-cell lymphoma, not otherwise specified: a retrospective single-center analysis].

We retrospectively analyzed clinical and pathological features, treatments, and prognoses in 28 patients with newly diagnosed peripheral T-cell lymphoma, not otherwise specified (PTCL-NOS) in Niigata University Medical and Dental Hospital. Of them, 16 were males and 12 were females, and their median age was 62.5 (range, 26-88) years.

[Successful umbilical cord blood hematopoietic stem cell transplantation in a patient with adult T-cell leukemia/lymphoma initially achieving complete remission with anti-CC chemokine receptor 4 antibody combined chemotherapy].

A 62-year-old man with CHOP refractory adult T-cell leukemia/lymphoma (ATLL) received anti-CC chemokine receptor 4 antibody (mogamulizumab) combined with CHOP and achieved complete remission. At 71 days after the final administration of mogamulizumab, he received umbilical cord blood transplantation (CBT) using reduced intensity conditioning. Umbilical cord blood engraftment was confirmed on day16.
