Jejunal hemolymphangioma: A case report.

Rationale: Hemolymphangioma is a benign tumor comprised of the newly-formed lymph spaces and blood vessels, which can usually be found in the head and neck of the affected children. There are few reports regarding cases with hemolymphangioma in small intestine, spleen, esophagus, and other organs.
Patient Concerns: Herein, a 55-year-old woman was presented in this study, she had complained of discomfort in the right upper abdomen for 2 months, and was discovered with a space-occupying lesion in proximal jejunum on computed tomography (CT). Eventually, the lesions were confirmed through double-balloon enteroscopy (DBE) to be located in the jejunum 60 cm away from the Treitz ligament.
Diagnose: Subsequently, the small intestine was partially resected, and postoperative pathology had confirmed the diagnosis of small intestinal hemolymphangioma.
Interventions: Excisional surgery of the lesion was planned. On surgery, the lesions were discovered to be about 33 cm to 22 cm when engorged the superficial vessels. No enlarged lymph nodes were seen at the root of the mesentery, and no obvious lesion was observed in the remaining small intestine.
Outcomes: Follow-up for 6 months showed no recurrence.
Lessons: Hemolymphangioma lacks typical clinical symptoms, and the correct preoperative diagnosis of hemolymphangioma remains challenging. Due to the increasing use of endoscopic diagnostic techniques, it is expected that hemolymphangioma in gastrointestinal tract may be detected and endoluminal located before surgery more feasibly. This case report aimed to highlight the contributions of CT and DBE to an accurate preoperative diagnosis and surgical strategy planning.
