Case of rectal angioleiomyoma in a female patient

Abstract

Angioleiomyoma represents a benign stromal tumor, which usually occurs in the subcutaneous tissue of the extremities, although its occurrence in the gastrointestinal tract is very rare. A case of rectal angioleiomyoma in a 40 year-old female patient is described here. Six months earlier, the patient suffered from periodical prolapse of an oval tumor from the anus, along with difficulties in bowel movement. A transanal extirpation of the tumor was performed. This is the first reported case in the English literature of a patient presenting with prolapsed angioleiomyoma of the rectum. During the immediate postoperative period, as well as 6 mo later, the patient had an unremarkable postoperative recovery.

A case of primary rectal angioleiomyoma: review of radiologic finding with histopathologic correlation

“…Primary angioleiomyomas of the rectum are even rarer. To the best of our knowledge, only one case of rectal angioleiomyoma has been reported in the English literature ( 2 ); however, that report did not describe any radiological findings.…”

“…They appear as skin or subcutaneous nodules in the extremities ( 1 ) and rarely develop in organs other than the skin. To the best of our knowledge, only one case of rectal angioleiomyoma has been reported in the English literature ( 2 ); however, in that case, the tumor was not described radiologically. Therefore, our case report is the first description of the radiological findings of a rectal angioleiomyoma.…”

Perianal Angioleiomyoma: A Case Report and Review of the Literature

“…Moreover, these benign neoplasias are often presented on the skin of lower extremities,[ 6 ] while less common localizations are hands, female reproductive organs, scrotum, mouth cavity, kidneys, and rectum. [ 3 7 8 9 10 11 ] Regarding the treatment of angioleiomyomas, local excision of the lesion and ligation of feeder vessels are the most common ways of treatment. [ 2 ] Nonetheless, our presented case appeared as a painless lump, and pain is the most referred clinical symptom of angioleiomyomas.…”

“…Regarding the histological division, angioleiomyomas can be classified into four types: (1) capillary/solid, which is the most common type and is characterized by the presence of smooth muscle fibers that surround slit-like vascular channels (preponderance in females); (2) venous, which is characterized by abundant vascular small channels with thickened muscular walls (preponderance in males); (3) cavernous, with a thin layer of smooth muscle cells that enclose wide vascular small channels (preponderance in males); and (4) a type of angioleiomyomas with combined characteristics between capillary and venous.
