Introduction. The diagnosis of B-cell lymphoma, unclassifiable, with features intermediate between diffuse large B-cell lymphoma (DLBCL) and classical Hodgkin’s lymphoma (cHL), also referred to as grey zone lymphoma (GZL), is a challenging diagnosis. There are no standardized guidelines; however, evidence strongly suggests that DLBCL-based regimens are effective in the treatment of GZL. Brentuximab vedotin (BV) is an anti-CD30 antibody drug conjugate that has established efficacy in relapsed/refractory Hodgkin and some T-cell lymphomas. There is some evidence that BV has a positive response in non-Hodgkin lymphoma (NHL) with a wide range of CD30 expressions—including GZL.Case. We present a case of a patient initially diagnosed with cHL who underwent repeat biopsy which was revealed to be GZL. Based on PET scanning and immunohistochemical studies, she was classified as a stage IIIA CD20+/CD30+ GZL patient. Given her strong CD30 expression, she underwent 6 cycles of R-BV-CHP (rituximab, brentuximab vedotin, cyclophosphamide, doxorubicin, and prednisone) chemotherapy and achieved complete response (CR) both clinically and radiographically.Discussion. Given the rarity of GZL, this case illustrates the immense challenges in making the diagnosis, discusses the current treatment options, and suggests that BV may be a viable therapeutic candidate in the treatment of GZL.

A female patient presented with severe, symptomatic multivessel spontaneous coronary artery dissection (SCAD) with no known medical history or risk factors. The affected vessels were left anterior descending artery (LAD), right coronary artery (RCA), and the ramus. She was treated with conservative medical management. Two months later, repeat coronary angiogram to evaluate for any residual disease was performed which showed near-complete resolution of all involved vessels.

A 60-year-old male was brought into the emergency department by EMS after he was found unresponsive by his neighbors. He was initially admitted to the hospital for chronic obstructive pulmonary disease exacerbation secondary to pneumonia. However, due to a sudden, rapidly progressing course of events, the patient was evaluated for COVID-19.
