Robotic assisted excision of retroperitoneal capillary hemangioma: a case report and review of literature

Objective This study presents a rare instance of retroperitoneal reproductive vascular capillary hemangioma, offering a review and critical discourse on pertinent scholarly works.Methods We conducted a detailed follow-up on a patient who received a robot-assisted laparoscopic excision for the said hemangioma. Postoperatively, the patient’s clinical data were meticulously monitored, and a thorough analysis of the hemangioma’s clinical profile was performed, integrating pathological assessments and immunohistochemical (IHC) findings to formulate innovative diagnostic and therapeutic perspectives.Results The pathological report of the patient’s left retroperitoneal tumor was a capillary hemangioma with a diameter of 3 cm and a gray-red, solid, soft-cut surface; IHC showed: CD31 (+), CD34 (+), CK-pan (−); The patient was followed up for 2 years without any signs of recurrence or metastasis.Conclusions Initial diagnostic considerations on retroperitoneal tumors should extend to capillary hemangiomas, which are often overlooked and prone to misdiagnosis; The early and judicious examination of retroperitoneal tumors, particularly utilizing abdominal enhanced CT when renal function is adequate, is of paramount importance for tumor localization and preliminary characterization; While hemangiomas are typically benign, the scarcity of retroperitoneal capillary hemangioma cases necessitates broader clinical studies and statistical analysis for a more nuanced understanding of these tumors.
