Among diffuse large b-cell lymphoma (DLBCL) subtypes, primary testicular lymphoma (PTL) has one of the highest risks of central nervous system (CNS) relapse. The converse, primary CNS lymphoma (PCNSL) relapse outside the CNS is rare. Molecular analysis has illustrated a genetic similarity between PTL and PCNSL. Here we present a case of a 64-year-old man with testicular relapse of PCNSL 20 months after a complete response to high dose methotrexate-based chemotherapy. His tumor demonstrated a molecular profile similar to both PCNSL and PTL on next generation sequencing, and molecular analysis confirmed common clonal origin of his CNS and testicular lesions. We review prior cases of testicular relapse of PCNSL, which lacked molecular investigations, and discuss the implications of the genomic findings in our patient, including future treatment options.

Background: Adenovirus infection is usually mild in presentation. However during pregnancy, the course can be more severe. Case: A 21-year-old woman in her second pregnancy presented with abdominal pain, vomiting, and fevers at 34 weeks and 4 days of gestation. Her respiratory pathogen panel on nasopharyngeal secretions was positive for adenovirus. Electrolytes were notable for hypomagnesaemia and persistent hypokalemia (nadir of 2.6 mmol/L) despite repletion but otherwise unremarkable. During her course, she developed rhabdomyolysis. During routine fetal monitoring at 35 weeks and 6 days of gestation, prolonged fetal bradycardia was identified, and an emergency caesarean delivery was performed. The infant had no clinical or laboratory evidence of adenovirus infection. The patient had a protracted clinical course but recovered with supportive care. Conclusion: Adenovirus can present with severe complications in a pregnant woman including hypokalemia and rhabdomyolysis. The mainstay of treatment is supportive care and monitoring of electrolyte abnormalities and renal function. [ABSTRACT FROM AUTHOR]
