- Gelatinous bone marrow transformation (GBMT) is a rare medical condition involving the atrophy of fat cells and the buildup of a gelatinous substance in the bone marrow, leading to decreased blood cell production (hypoplastic hematopoiesis).
- A study reviewed bone marrow specimens from patients with a BMI of <18.5, revealing that 30% of those evaluated had GBMT associated with ring sideroblasts, a specific type of abnormal red blood cell.
- Notably, one patient’s ring sideroblasts were linked to copper deficiency, highlighting that GBMT may be misdiagnosed as myelodysplastic syndrome without further investigation.
Primary central nervous system (CNS) diffuse large B-cell lymphoma with MYC and BCL2 rearrangements is a very rare lymphoma subtype. Deep brain stimulation is an effective minimally invasive therapeutic option for the treatment of refractory movement disorders, as well as some psychiatric disorders and chronic pain syndromes. Herein, we report a case of CNS lymphoma, which developed around an electrode of a deep brain stimulation (DBS) device.

- Breast implant-associated anaplastic large cell lymphoma is classified as a distinct type of cancer linked to textured breast implants, prompting new challenges for medical professionals handling patients with these devices.
- While much focus has been on this more serious lymphoma, benign issues related to breast implants also affect 20-30% of patients, necessitating careful assessment.
- The review discusses a variety of benign complications, detailing their clinical presentations and imaging features, and outlines a structured method for diagnosing and managing breast implant-related specimens.
