Insights
Laparoscopic surgery successfully treated a giant malignant lymphoma of the ileocecum in a 78-year-old man. This minimally invasive approach offers a viable option for resecting gastrointestinal lymphomas.
Area of Science:
- Gastroenterology
- Surgical Oncology
- Pathology
Background:
- Malignant lymphoma of the ileocecum is rare.
- Giant tumors pose diagnostic and surgical challenges.
Observation:
- A 78-year-old male presented with right flank pain.
- Imaging revealed a large ileocecal tumor.
- Biopsy suggested lymphoma or adenocarcinoma.
Findings:
- Laparoscopic ileocecal resection was performed for diagnosis and treatment.
- Pathology confirmed malignant diffuse large B-cell lymphoma.
- The patient had an uneventful postoperative recovery and is undergoing chemotherapy.
Implications:
- Laparoscopic surgery is a feasible and effective treatment for gastrointestinal malignant lymphoma.
- Minimally invasive resection can be considered for ileocecal lymphoma.
- Early diagnosis and tailored treatment are crucial for patient outcomes.
Abstract:
We experienced a case ofa giant malignant lymphoma ofthe ileocecum treated with laparoscopic surgery. A 78-year-old man presented with right flank pain. Lower endoscopy and abdominal computed tomography revealed a giant tumor in ileocecum. Biopsy results suggested malignant lymphoma or adenocarcinoma. We performed a laparoscopic ileocecal resection for definite diagnosis and treatment. The postoperative course was uneventful. The pathological diagnosis was malignant diffuse large B-cell lymphoma. The patient underwent chemotherapy and is being followed. Laparoscopic surgery can be considered useful to resect gastrointestinal malignant lymphoma.
