Abstract Primary dural Hodgkin lymphoma (PDHL) is an extremely rare subset of Hodgkin lymphoma (HL). Its existence is controversial, as Hodgkin lymphoma is not traditionally thought to arise from the central nervous system (CNS) or its meninges and only 0.02% of patients with Hodgkin lymphoma have any CNS involvement. We report a case of a 71‐year‐old Caucasian man who presented with progressive fatigue and sudden onset slurred speech, disorientation, and memory loss. Brain imaging identified a large extra‐axial right frontal mass, and he underwent urgent subtotal resection. Pathology and subsequent workup revealed Stage IAE classical Hodgkin lymphoma of the right frontal dura, with no extra‐cranial disease or leptomeningeal spread detected. The patient was subsequently treated with ABVD chemotherapy (completed 2.5 of 4 planned cycles) and 36 Gy in 20 fractions of consolidative involved‐site radiotherapy (ISRT). He has been followed for 5 years with no clinical or radiological signs of recurrence. This is the second confirmed case of intracranial PDHL reported in the literature, with the longest follow‐up for any case of PDHL.

Abstract Introduction This resource combines a variety of teaching tools to supplement bedside supervised teaching of the bone marrow aspirate and biopsy procedure with an emphasis on underlying deep anatomy. Methods This resources provides a video with a visualization exercise using live participants, cadavers, and skeletons to teach underlying anatomy involved in performing bone marrow procedures, in addition to a review of technical procedure-techniques. Also included is a PowerPoint presentation developed to address indications, contraindications, and risks of bone marrow procedures that can be used at a clinical teaching session. Results At pretest, 48% (15 out of 31) of residents landmarked accurately. At posttest, 74% (23 out of 31) of residents accurately performed the procedure. McNemar's test revealed a non-significant trend towards increased performance at posttest. A Wilcoxon signed-rank test demonstrates a significant difference between pre and posttest accuracy in the 16 residents initially inaccurate at pretest. No association was detected between participant demographics and pretest accuracy. Discussion Our study suggests that this anatomy-based video exercise improved resident procedural performance as measured by landmarking accuracy. Future research is needed to explore application of this form of intervention on teaching medical procedures. Using this easily-accessed intervention at point-of-care in programs would enhance its impact beyond that realized from our single teaching session.

Extramedullary relapse of acute lymphoblastic leukemia (ALL) is rare and has been primarily reported in pediatric patients or hematopoietic stem cell transplant recipients. We report a case of a 62-year-old woman who presented with relapsed ALL involving her kidneys, pancreas, and bone marrow 2 years after completing chemotherapy with a standard ALL protocol. Unfortunately, her extramedullary disease progressed despite treatment. To the best of our knowledge, this is the first reported case of extramedullary relapse of B-cell ALL to the kidneys and pancreas occurring in an adult patient who had not previously undergone a hematopoietic stem cell transplant. A literature review of kidney and pancreatic extramedullary relapse in ALL is also included.
