Summary
This case study details a rare retroperitoneal mixed capillary venous hemangioma in a 61-year-old male. Surgical excision and immunohistochemistry confirmed the diagnosis of this vascular tumor.
Area of Science:
- Vascular Surgery
- Surgical Pathology
- Diagnostic Imaging
Background:
- Retroperitoneal tumors are uncommon, and vascular malformations like hemangiomas are rare in this location.
- Accurate preoperative diagnosis is crucial for appropriate surgical planning and management.
Purpose of the Study:
- To report a case of mixed capillary venous hemangioma in the retroperitoneum.
- To highlight the diagnostic features on imaging and confirm with histopathology and immunohistochemistry.
Main Methods:
- A 61-year-old male presented with a retroperitoneal mass.
- Diagnostic imaging included abdominal ultrasonography and dynamic contrast-enhanced computed tomography (CECT).
- The mass was surgically excised laparoscopically, followed by histological and immunohistochemical analysis.
Main Results:
- Ultrasonography showed a hypoechoic mass with increased vascular flow.
- CECT revealed centripetal enhancement, suggestive of a hemangioma.
- Immunohistochemistry was positive for CD31 and CD34, confirming vascular origin, and negative for other markers.
- Histological examination confirmed a mixed capillary venous hemangioma.
Conclusions:
- Mixed capillary venous hemangioma is a rare retroperitoneal neoplasm.
- Multimodality imaging, including CECT, is valuable for preoperative diagnosis.
- Laparoscopic excision is a feasible treatment option, and definitive diagnosis relies on histopathology and immunohistochemistry.

01:22Portal Hypertension
Portal hypertension is an increase in blood pressure within the portal venous system. Normally, this pressure is less than 5 mmHg. It is considered clinically significant when it rises above 10 mmHg. At this threshold, complications from altered blood flow and venous congestion emerge.EtiologyPortal hypertension arises from conditions that impede blood flow through the liver. The most common cause is cirrhosis, in which chronic liver injury leads to fibrotic scarring. This fibrosis narrows or...
01:20Venous Thrombosis II: Clinical Manifestations and Diagnostic Studies
The key difference between Superficial Vein Thrombosis (SVT) and Deep Vein Thrombosis (DVT) lies in their location and severity.Clinical ManifestationsSVT typically presents with localized pain, tenderness, and redness along the course of a superficial vein, often accompanied by a palpable, cord-like structure under the skin. This condition is usually less dangerous than DVT but can be uncomfortable and may lead to complications such as cellulitis or, rarely, a clot extension into the deep...
01:28Esophageal Varices-II: Clinical Features and Management
Esophageal varices often manifest as gastrointestinal bleeding episodes, presenting symptoms like hematemesis (vomiting of blood), hematochezia (passing fresh blood via the rectum), and melena (black, tarry stools). Other signs can include weight loss, anorexia, abdominal discomfort, jaundice, pruritus, altered mental status, and muscle cramps.
