Summary

A rare uterine T-cell lymphoma, negative for Human T-lymphotropic virus type 1 (HTLV-1), was identified alongside atypical endometrial hyperplasia. This marks the first reported case of primary T-cell lymphoma originating in the uterus.

Area of Science:

  • Gynecologic Oncology
  • Hematology
  • Pathology

Background:

  • Endometrial hyperplasia is a common condition with varying degrees of atypia.
  • Uterine malignancies encompass a range of epithelial and mesenchymal tumors.
  • Lymphomas primarily affect lymphoid tissues, with rare extranodal presentations.

Observation:

  • A 63-year-old Japanese woman presented with findings suggestive of uterine pathology.
  • Histopathological examination revealed a CD8-positive T-cell lymphoma within the uterine tissue.
  • The lymphoma was confirmed to be negative for Human T-lymphotropic virus type 1 (HTLV-1).
  • Atypical endometrial hyperplasia was concurrently observed in the same patient.

Findings:

  • The study describes a novel case of primary uterine T-cell lymphoma.

  • This represents the first documented instance of a T-cell lymphoma originating in the uterus.
  • The tumor was characterized as CD8-positive and HTLV-1-negative.

    • Implications:

    • This case expands the known spectrum of extranodal lymphomas.
    • It highlights the importance of considering lymphoma in the differential diagnosis of uterine lesions, particularly atypical hyperplasia.
    • Further research is needed to understand the pathogenesis and optimal management of primary uterine T-cell lymphoma.
