Study summary

The purpose of this study is to describe the clinical, biological, and radiographic characteristics at the time of cryptococcosis diagnosis, as well as the time interval between the initiation of BTK inhibitor therapy and the diagnosis of cryptococcosis.

And also, the clinical course of each patient at 12 months in order to evaluate the susceptibility to cryptococcosis correlated with BTK inhibitor therapy.
