Isolated metastasis to colon from carcinoma cervix

Sigmoid colonic metastasis from a squamous cell carcinoma of the cervix: A rare case report with literature review

RATIONALE

As the third most common cancer in women, cervical cancer usually spreads to adjacent organs. Distant metastasis from the cervix to the gastrointestinal tract is an extremely rare occurrence.

PATIENT CONCERNS

Herein, we present a rare case of a 57-year-old woman who was treated by hysterectomy and bilateral salpingo-oophorectomy with pelvic lymphadenectomy for squamous cell carcinoma (SCC) of the uterine cervix. A metastatic location in the sigmoid colon was revealed after 8 years causing an acute intestinal obstruction in this patient.

DIAGNOSES

Final surgical pathology showed an invasive lesion with squamous differentiation in full thickness of the colon wall from mucosa to serosa. Meanwhile, the results of immunohistochemistry (IHC) showed the cancer cells were positive for CK5/6, P63, P40, and P16 confirming the diagnosis of metastatic sigmoid colonic carcinoma originating from SCC of the uterine cervix.

INTERVENTIONS

Sigmoid colon resection with lymph node dissection followed by adjuvant chemotherapy (paclitaxel, carboplatin, and paprillizumab) was performed on the patient.

OUTCOMES

The patient was disease-free 16 months after surgery.

LESSONS SUBSECTIONS

SCC is one of the rare malignant tumors of the gastrointestinal tract occurring as either a primary or secondary lesion. However, the secondary SCC of the colon has a poorer prognosis compared with the primary SCC. Therefore, colonic metastasis must be considered in the differential diagnosis of acute intestinal obstruction, especially in patients with the medical history of SCC in other organs.

Postoperation of cervical cancer with intestine metastasis: a case report and literature review

Background

Cervical cancer can infiltrate locally and directly spread to adjacent organs including the vagina, peritoneum, urinary bladder, ureters, rectum, and paracervical tissue, but the intestine metastasis from cervical cancer is extremely rare, which can easily be misdiagnosed.

Case presentation

Here, we report a case about a 45-year-old postoperative cervical cancer patient with metastases to small intestine and sigmoid colon who presented abdominal distention and dull pain due to intestinal obstruction. The patient underwent exploratory laparotomy, and two intestinal segments including the tumors were resected. The postoperative pathological diagnosis illustrated sigmoid colon and terminal ileum metastatic squamous cell carcinoma.

Conclusions

This case demonstrates that intestine metastasis must be considered in the differential diagnosis of acute abdomen in patients with cervical cancer even at an early tumor stage.
