Non-nodal mantle cell lymphoma mimicking hairy cell leukemia.

This case of non-nodal mantle cell lymphoma (MCL) showcases atypical hairy cell-like features, distinguishing it via next-generation sequencing. Despite a TP53 mutation indicating poor prognosis, our case followed an indolent course, highlighting the importance of genetic testing and phenotypical examination in MCL.

Intravascular lymphoma masquerading as septic shock.

Intravascular lymphoma (IVL) is a rare type of extranodal lymphoma that selectively affects small blood vessels. We report a patient who presented with dyspnea and weight loss as well as refractory shock and multiple-organ dysfunction. The postmortem revealed disseminated involvement of an IVL but no evidence of infection.
