Brucella may cause testicular masses, which may be confused with a testicular tumour. We present the case of a man with fever and oedema in the scrotum. Ultrasound and colour Doppler ultrasound with a 6 to 15 MHz high-frequency linear-array transducer was performed, revealing bilateral scrotal wall oedema, heterogeneous echo texture and slightly increased vascularization of the right testis, with hypoechoic lesions characterized by hypervascular margins and no flow within them. These findings were compatible with testicular abscesses. Three blood cultures grew Brucella melitensis, so the patient received treatment with doxycycline and rifampin for 8 weeks, which resulted in disappearance of the testicular abscesses.

A significant percentage of B-cell lymphomas are characterized by bone marrow involvement (BMI) at diagnosis. In most cases, there is concordance between the type of lymphoma present in the lymph node and the lymphoma present in the bone marrow. Herein, we present a sixty-seven years old female patient, who was diagnosed with High-Grade B-cell Lymphoma (HGBL) in the bone marrow, while simultaneously, in the peripheral lymph node, the presence of Follicular Lymphoma (FL) was noted. The patient presented to the hospital with spontaneous tumor lysis syndrome, a finding compatible with the aggressive course of the HGBL. To our knowledge, this is the first case of the co-existence of HGBL in the bone marrow and FL in a lymph node, which might be attributed to merely a coincidence or to the transformation of the cells in the preferable milieu of the bone marrow.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
