Primary extranodal marginal zone B-cell lymphoma of the fallopian tube

Abstract

Background: Only 2% of all extranodal primary lymphomas affect the female genital tract. Involvement of the fallopian tubes by primary lymphoma is extremely rare.

Case: A 34-year-old patient presented with the symptoms of salpingitis. Laparoscopy with salpingectomy was performed. Salpingitis caused by Acinetobacter species was diagnosed and antibiotic treatment was administered. Histologic examination of the fallopian tube revealed primary extranodal marginal zone B-cell lymphoma (MALT-type lymphoma) of the fallopian tube. After 12 months no tumoral recurrence occurred.

Conclusion: Although the female genital tract is rich in mucosa and the existence of mucosa-associated lymphoid tissue (MALT) has been demonstrated previously, extranodal marginal zone B-cell lymphoma of the fallopian tube is exceptional. To our knowledge only two cases with extranodal marginal zone B-cell lymphoma of the fallopian tube have been previously reported. Existence of inflammation close to the tumor is interesting to emphasize.
