Early postsurgical lethal outcome due to splenic littoral cell angioma: A case report.

BACKGROUND

Littoral cell angioma (LCA) is a rare benign vascular tumor of the spleen. Given its rarity, standard diagnostic and therapeutic recommendations have yet to be developed for reported cases. Splenectomy is the only method of obtaining a pathological diagnosis and providing treatment to obtain a favorable prognosis.

CASE SUMMARY: A 33-year-old female presented with abdominal pain for one month. Computed tomography and ultrasound revealed splenomegaly with multiple lesions and two accessory spleens. The patient underwent laparoscopic total splenectomy and accessory splenectomy, and splenic LCA was confirmed by pathology. Four months after surgery, the patient presented with acute liver failure, was readmitted, rapidly progressed to multiple organ dysfunction syndrome and died.

CONCLUSION

Preoperative diagnosis of LCA is challenging. We systematically reviewed online databases to identify the relevant literature and found a close relationship between malignancy and immunodysregulation. When a patient suffers from both splenic tumors and malignancy or immune-related disease, LCA is possible. Due to potential malignancy, total splenectomy (including accessory spleen) and regular follow-up after surgery are recommended. If LCA is diagnosed after surgery, a comprehensive postoperative examination is needed.
