Rectal cancer in pregnancy : a diagnostic and therapeutic challenge

الملخص EN

Introduction : The occurrence of colorectal cancer during pregnancy is rare and is associated with diagnostic and therapeutic challenges.

Herein, we report such a case of rectal cancer in pregnancy and review the literature.

Case report : A 31-year-old multiparous, pregnant woman, in the 20th week of gestation, presented with rectal bleeding progressing to spasmodic abdominal pain and right flank vague pain.

A flexible rectosigmoidoscopy showed a large ulcerative mass located in the rectosigmoid junction, 15 cm away from anal verge.

Imaging studies and biopsy proved it to be rectal adenocarcinoma with single liver metastasis.

The patient’s pregnancy was terminated and neoadjuvant therapy followed by curative surgery was performed.

She is currently receiving adjuvant systemic therapy to eradicate potential micrometastatic disease.

Conclusion : This case suggests that colorectal cancer can mimic the signs and the symptoms of pregnancy and tends to present at an advanced stage in pregnant women.
