Transumbilical single-site laparoscopic resection of splenic papillary angioendothelioma in a pediatric patient: a rare case report and review of literature

Pediatric splenic PILA is diagnostically challenging because of its rarity and overlapping radiological features with other vascular neoplasms. Complete surgical excision and longitudinal surveillance are critical to mitigate the risk of local recurrence or metastasis, given the tumor's borderline malignant potential. Single-port laparoscopic partial splenectomy represents a feasible, minimally invasive approach for pediatric patients, balancing oncological safety with preservation of splenic function. This case underscores the importance of integrating intraoperative frozen-section analysis and advanced imaging to guide surgical decision-making, particularly in children.
