Summary

This case report details a rare MALT lymphoma in the uvula and breast of a woman with Sjögren syndrome. Progesterone may have influenced the breast tumor development, suggesting hormonal links to MALT lymphoma.

Area of Science:

  • Oncology
  • Immunology
  • Endocrinology

Background:

  • Marginal zone B cell lymphoma of mucosa-associated lymphoid tissue (MALT) type can occur in various extranodal sites.
  • Sjögren syndrome (SS) is an autoimmune disorder associated with an increased risk of MALT lymphoma.
  • Hormonal influences on lymphomagenesis are increasingly recognized.

Observation:

  • A 30-year-old woman with Sjögren syndrome presented with MALT lymphoma in the uvula and breast.
  • The patient had a history of childbirth and lactation.
  • Immunohistochemical analysis revealed progesterone receptor expression in the lymphoid cells of the breast.

Findings:

  • MALT lymphoma of the uvula was associated with Sjögren syndrome.
  • Progesterone receptor expression suggests a potential role for progesterone in the development of breast MALT lymphoma.

Related Experiment Videos

  • The interplay between autoimmune conditions, hormonal factors, and MALT lymphoma is highlighted.

    • Implications:

    • This case suggests a potential hormonal influence, specifically progesterone, on the development of MALT lymphoma in the breast.
    • Further research is warranted to explore the relationship between reproductive hormones and MALT lymphoma in patients with autoimmune diseases.
    • Understanding these associations may lead to novel diagnostic or therapeutic strategies for MALT lymphoma.
