Insights
This case report details a rectal mucosa-associated lymphoid tissue (MALT) lymphoma successfully treated with surgery. The patient experienced no recurrence for nearly three years, highlighting surgical resection as an effective therapy.
Area of Science:
- Gastroenterology
- Oncology
- Surgical Pathology
Background:
- Rectal mucosa-associated lymphoid tissue (MALT) lymphoma is a rare extranodal non-Hodgkin lymphoma.
- Early diagnosis and appropriate treatment are crucial for favorable outcomes.
Observation:
- A 64-year-old woman presented with occult blood in stool and a palpable rectal mass.
- Histopathological examination of biopsy specimens confirmed MALT lymphoma of the rectum.
Findings:
- The patient underwent abdominoperineal excision of the rectum.
- No adjuvant chemotherapy was administered.
- The patient remained disease-free with no recurrence for 2 years and 11 months post-surgery.
Implications:
- Surgical resection is a viable and effective treatment modality for rectal MALT lymphoma.
- This case underscores the importance of considering MALT lymphoma in the differential diagnosis of rectal masses.
- Further research into optimal management strategies for rectal MALT lymphoma is warranted.
Abstract:
A case of mucosa-associated lymphoid tissue (MALT) lymphoma of the rectum is reported. A 64 year-old woman was referred to us for the evaluation of occult blood in the stool. A hard mass was palpable on digital examination. Biopsy specimens revealed a histologic picture compatible with MALT lymphoma. Abdominoperineal excision of the rectum was carried out. Chemotherapy was not performed, and the post-operative course was uneventful, with no evidence of recurrence for 2 years and 11 months. Surgical resection is an effective therapy for MALT lymphoma of the rectum.
