Primary mucosa-associated lymphoid tissue lymphoma in fallopian tubes: A case report and literature review

Rationale:
Mucosa-associated lymphoid tissue (MALT) lymphoma accounts for 7%-8% of newly diagnosed lymphomas. The stomach is the most common organ of origin (nearly 50% of MALT lymphomas). Only 2% of MALT lymphomas arise from the female genital tract, and most originated from uterus. We described a rare case of MALT lymphoma primarily arising from the fallopian tube.
Patient Concerns:
A 26-year-old woman was brought into our gynecological clinic because of a history of irregular menstruation. The transvaginal ultrasonography revealed cystic masses in bilateral adnexa and both of them showed rich vasculature. Laboratory tests showed a high level (455.3 U/mL) of cancer antigen-125 (CA-125).
Interventions:
A laparoscopy was performed.
Outcomes:
Frozen section of the removed specimen revealed acute and chronic inflammation with abundant inflammatory cells infiltrating the mesenchyme. The right fallopian tube was removed. However, the final histological results showed inflammation accompanied by hyperplasia of lymphoid tissue. Immunohistochemistry staining were consistent with MALT lymphoma. The patient received the second surgery to remove the left fallopian tube and also confirmed the same pathology.
Lessons:
Gynecologists should be aware of cystic masses which showed rich vasculature and high level of CA-125.
