A Giant Retroperitoneal Lymphangioma: A Case Report

Area of Science:

• Pediatric Surgery
• Surgical Oncology
• Gastrointestinal Surgery

Background:

• Lymphangiomas are congenital malformations of the lymphatic system, commonly affecting the head and neck in children.
• Intra-abdominal lymphangiomas are exceptionally rare, particularly in adults, often leading to diagnostic complexities.
• While frequently asymptomatic, lymphangiomas can manifest as acute abdominal conditions.

Observation:

• This report details an unusual case of a massive, asymptomatic retroperitoneal lymphangioma in an adult patient.
• The retroperitoneal location and large size of the tumor presented unique diagnostic and surgical considerations.
• The patient remained asymptomatic prior to diagnosis, underscoring the potential for silent progression.

Findings:

• Complete surgical excision of the retroperitoneal lymphangioma was successfully achieved.
• The postoperative period was uneventful, indicating a favorable outcome following surgical intervention.
• Histopathological confirmation of lymphangioma was established post-excision.

Implications:

• This case expands the understanding of adult intra-abdominal lymphangioma presentations and management.
• It emphasizes the importance of considering rare diagnoses in adult patients with abdominal masses.
• Successful surgical excision offers a curative option for symptomatic or incidentally discovered retroperitoneal lymphangiomas.
