Recurrence of carcinoma cervix in the scar of previous cesarean section: a case report.

Although rare, reports of carcinoma cervix recurring in abdominal incision, episiotomy scars, laparoscopic port sites, and drain sites are available. However, recurrence in the scar of a previous cesarean section (CS) is unreported. A 49-year-old female with a diagnosis of keratinizing squamous cell carcinoma (SCC) of cervix, stage IIB, was treated by radical radiotherapy. She had undergone CS, through midline abdominal incision, for three previous deliveries. Twenty months later, she presented with a nodule of size 2.5 x 2 cm(2) on the 26-year-old abdominal CS scar. Infiltration of the skin and extension into the deeper structures of the abdominal wall was present in an area of 5 x 4 cm(2). There was no evidence of disease on the cervix. A fine-needle aspiration cytologic examination from the nodule revealed keratinizing SCC. Ultrasonography and computerized tomography scan revealed a mass lesion along the abdominal CS scar with subcutaneous nodule and peritoneal extension. Multiple metastatic lesions were present in the liver. She was treated with chemotherapy and radiotherapy. The patient has lived for more than 12.5 months. The first report of recurrence of carcinoma cervix in a CS scar is presented. Literature on surgical scar recurrence in carcinoma cervix is reviewed.
