Angiomyoma and vascular ectasia of the small bowel as a cause of intestinal bleeding

Small intestine angioleiomyoma as a rare cause of perforation: A case report

BACKGROUND

Angioleiomyoma is a rare and benign stromal tumor typically found in subcutaneous tissue. It rarely occurs in the gastrointestinal tract. Among the reported cases, the most common complication was gastrointestinal bleeding. Perforation has only been reported as a complication in the last few decades.

CASE SUMMARY

This case report detailed the discovery of intestinal angioleiomyoma in a 47-year-old male presenting with abdominal pain that had persisted for 3 d. After suspecting hollow organ perforation, surgical intervention involving intestinal resection and anastomosis was performed.

CONCLUSION

The report underscores the significance of early surgical intervention in effectively treating angioleiomyoma while emphasizing the pivotal role of timely and appropriate measures for favorable outcomes.

A Small Jejunal Angioleiomyoma Detected by Double-Balloon Enteroscopy: A Case Report

BACKGROUND Angioleiomyoma in the small intestine is a rare cause of gastrointestinal bleeding. Only 7 cases of angioleiomyoma in the small intestine were reported in the English literature, with 4 of them causing gastrointestinal bleeding. The diagnosis of angioleiomyomas in the small intestine before surgery is difficult. CASE REPORT We report the case of a 42-year-old man with recurrent melena who underwent repeated esophagogastroduodenoscopy and colonoscopy, without positive finding. During a double-balloon enteroscopy, an elevated lesion with a diameter of 6 mm was found in the jejunum. The lesion was resected laparoscopically assisted with double-balloon enteroscpy. A microscopic examination showed fibric membrane of the mass and numerous vascular channels surrounded by proliferated smooth muscle. There were exudative fibrin and many thrombi formed by red blood cells. Immunohistochemistry was positive for SMA and CD34. A pathological diagnosis of jejunal angioleiomyoma with thrombus was established. During a 5-year follow-up, there was no further gastrointestinal bleeding. CONCLUSIONS The gastroenterologists should consider angioleiomyoma in the small intestine when assessing obscure gastrointestinal bleeding.

Recurrent Midgut Bleeding due to Jejunal Angioleiomyoma

Angioleiomyoma being a type of true smooth muscle gastrointestinal tumors can lead to serious life-threatening gastrointestinal bleeding. We report a case of 21-year-old male patient with recurrent midgut bleeding. Contrast-enhanced CT revealed highly vascular small bowel neoplasm. The patient underwent laparotomy with bowel resection and recovered uneventfully. Histopathology revealed jejunal angioleiomyoma.

Leiomyosarcoma of the small intestine presenting as fever of unknown origin

We report a patient with a jejunal leiomyosarcoma who presented with fever of unknown origin. Resection of the tumour resulted in resolution of his symptoms.
