Abstract

fetched live from OpenAlex

Hodgkin lymphoma (HL) is a hematologic malignancy that comprises about 10% of all lymphomas with the most common type being classical HL (cHL). The typical clinical presentation of cHL involves multiple region lymphadenopathy and a chest mass found on imaging. However, not all patients present with the typical symptomology of cHL which poses a diagnostic challenge. Extranodal HL, especially primary bone marrow HL (PBMHL), has been described in immunocompromised patients with human immunodeficiency virus (HIV). In this case report, we present a PBMHL case in an immunocompetent patient with no HIV exposure. We discuss a 51-year-old immunocompetent female who presented with 2 - 3 months of fever, confusion, generalized myalgias, and fatigue. She had no lymphadenopathy on physical exam. On further testing, the patient's blood work demonstrated cytopenia and imaging confirmed no lymphadenopathy. Eventually, a bone marrow evaluation established her diagnosis of PBMHL. The patient expired after receiving one cycle of a modified chemotherapy regimen. This case illustrates that HL can be associated with an atypical clinical presentation which may delay diagnosis and treatment. PBMHL can occur in the normal population who is not immunocompromised nor HIV positive. In this situation, the best diagnostic approach is a thorough medical history, physical exam, and bone marrow aspiration and biopsy. Presence of constitutional symptoms without any lymphadenopathy or chest mass should raise the concern for possible atypical HL such as PBMHL. Accurate and timely identification of PBMHL allows for timely initiation of appropriate therapy. While cHL is responsive to chemotherapy, further research is required to improve the therapy for PBMHL.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
