Schwannoma of the sigmoid colon

et al. 2015

Colonic schwannomas are very rare gastrointestinal tumours originating from Schwann cells, which form the neural sheath. Primary schwannomas of the lower gastrointestinal tract are very rare and usually benign in nature. However, if they are not surgically removed, malign degeneration can occur. We report a case of a 79-year-old woman who presented to our clinic with rectal bleeding and constipation. She underwent a lower gastrointestinal tract endoscopy. A mass subtotally obstructing the lumen of the sigmoid colon was seen and biopsies were taken. Histopathological examination indicated a suspicion of gastrointestinal tumour and the patient underwent sigmoid colon resection after preoperative evaluation by laboratory analysis, abdominal ultrasonography and CT. Her postoperative course was uneventful and she was discharged on the fifth day for outpatient control. The histopathology report revealed schwannoma of the sigmoid colon. This was a case of schwannoma of the sigmoid colon that was successfully treated with total resection.

Schwannomas are rare tumors that arise from Schwann cells in neural sheaths. They are commonly found in the central nervous system, spinal cord, or peripheral nerves of the body. Occasionally, they occur in the gastrointestinal tract, with the stomach being the most common site. However, colorectal and retroperitoneal schwannomas are very rare. Preoperative diagnosis is often difficult and definitive treatment entails surgical excision. We herein present 3 cases of intraabdominal schwannomas.

“…2 In addition, gastrointestinal schwannomas are most commonly in the stomach, whereas extremely rare in the rectum. 3,4 Most rectal schwannoma grow slowly and are asymptomatic; sometime they may cause rectal bleeding, colonic obstruction, defecation disorders, and pain. [3][4][5] Gastrointestinal schwannoma grossly and clinically resembles gastrointestinal stromal tumor (GIST).…”

[3][4][5] Gastrointestinal schwannoma grossly and clinically resembles gastrointestinal stromal tumor (GIST). However, the distinction between schwannoma and GIST is important because the former is benign even when large and mitotically active; moreover, the treatment and prognosis can differ markedly.…”

Simultaneous Rectal Schwannoma and Prostatic Adenocarcinoma Detected on FDG PET/CT

A case of an 84-year-old man with suspicious rectal cancer has been reported. The patient underwent FDG PET/CT for whole-body survey. Unexpectedly, FDG PET/CT demonstrated abnormally increased FDG uptake in rectum (SUV max : 3.33) and prostate (SUV max : 5.66) simultaneously. Ultimately, biopsies of rectal tumor and prostatic gland confirmed diagnoses of synchronous schwannoma in the rectum and adenocarcinoma in the prostate. To our best knowledge, this is the first case of rectal schwannoma with representative FDG PET/CT scan in the literature.
