“…Abdominoperineal resection (APR) was performed for 11 of 24 patients (45.8%). On the other hand, including our case, 10 patients (41.6%) were treated with local resection of the anal tumor as an anus-preserving curative operation [15–22]. Among 10 patients, 7 patients underwent perioperative chemotherapy or chemoradiotherapy.…”

A rare case of rectal cancer with perianal metastasis: a case report

Background Cancer metastasis from colon cancer to an anal fistula is very rare. We herein reported a rare case in which local excision was performed for metastatic anal fistula cancer originating from rectal cancer. Case presentation A 68-year-old man was referred to our institution with a diagnosis of rectal cancer. He had complained of anal fistula for 5 years. Based on a recent history of cerebral infarction, Hartmann’s operation was performed to treat the rectal cancer after the administration of preoperative chemotherapy for 3 months. However, 1 month after Hartmann’s operation, the anal fistula was found to have worsened. Pelvic magnetic resonance imaging (MRI) revealed tumor formation at the perianal lesion. Metastatic anal fistula cancer originating from the rectal cancer was diagnosed based on the examination of the biopsied tissue. We selected local excision because the anal tumor had not invaded the surrounding tissue. There has been no recurrence in the 31 months after the curative operation. Conclusion Metastatic cancer should be ruled out when treating left-sided colon cancer with anal fistula. Local excision is one possible treatment for metastatic anal fistula cancer.

“…We performed a pan-proctocolectomy after neo-adjuvant chemotherapy, because the patient developed an LBO. Three other case reports have also demonstrated lymph node involvement, with metastases in the liver, peritoneum, or lungs [ 1 , 7 - 8 ]. However, as there are a limited number of reports, with short periods of follow-up, the prognosis and best therapy for individual patients cannot be determined.…”

Synchronous Sigmoid Colon Cancer Seeding a Fistula-in-Ano

A seeded fistula-in-ano from a synchronous sigmoid colon cancer is rare. The literature is still divided regarding the standard treatment, although an abdominoperineal resection is considered the best option when curative resection is possible.This case is distinct from previous reports, as the patient had known metastatic liver disease before surgery, and proceeded with a pan-proctocolectomy after neo-adjuvant chemotherapy. The patient died 20 months post-operatively of his metastatic liver disease, having been otherwise asymptomatic for eight months on continued chemotherapy, before commencing palliative treatment (completed five cycles).Given its rarity, a low suspicion to biopsy a fistula-in-ano is advocated, and the exclusion of malignancy should be considered prior to surgery.
