Umbilical Adenocarcinoma: When a Belly Button Becomes a Battleground

"Discover how recurrent sweat gland umbilical adenocarcinoma is treated with wide excision and reconstruction surgery combined with chemotherapy to prevent recurrence."


Adenocarcinoma found in the umbilicus is an exceedingly rare occurrence. Most often, when cancer appears in this region, it's due to secondary events—metastasis from another primary site. However, in even rarer instances, the cancer originates from the sweat glands located in the umbilicus itself, presenting unique challenges due to its resistance to radiation and unpredictable clinical appearance.

Recently, a case study detailed the experience of a 37-year-old woman who faced recurrent umbilical adenocarcinoma. Her journey involved previous tumor surgery followed by chemotherapy. The cancer's return prompted an aggressive treatment strategy that offers insights into managing this rare condition.

This article delves into the specifics of this case, exploring the diagnostic approaches, surgical techniques, and the role of chemotherapy in preventing recurrence. By examining this instance, we aim to shed light on the complexities of treating sweat gland umbilical adenocarcinoma and the potential for improved outcomes.

The Case: Recurrence and the Road to Reconstruction

The patient's ordeal began when she noticed a painless nodule in her umbilicus. A prior surgery, 14 months before, confirmed moderately-differentiated adenocarcinoma. Despite undergoing six cycles of oral chemotherapy with Capecitabine, the tumor recurred, highlighting the aggressive nature of this cancer. The recurrence prompted a more comprehensive diagnostic and therapeutic approach.

Diagnostic tests, including a Fine Needle Aspiration Biopsy (FNAB), confirmed the presence of malignant cells. A colonoscopy ruled out the possibility of the tumor being a secondary metastasis from the colon. The results of the CT scan revealed no distant metastasis. The surgical team then proceeded with a wide excision surgery, removing the tumor along with a 5 cm margin of surrounding tissue. This procedure left a significant 17 cm defect on the anterior abdominal wall, necessitating reconstructive surgery.
  • Surgical Strategy: The surgical team's decisions were guided by a thorough review of the patient's previous pathological reports.
  • Goal of Surgery: Complete removal of the tumor, ensuring that both the gross and microscopic margins were free of cancerous cells.
  • Margin: Aimed to achieve a wide margin during the excision to minimize the risk of recurrence.
The reconstruction involved using an anti-adhesive Parietex polyester mesh, measuring 30 x 30 cm, to repair the abdominal wall defect. Histopathology of the excised tissue confirmed the diagnosis of sudoriferous gland adenocarcinoma, with no tumor cells found in the adjacent tissues. The patient then continued additional chemotherapy with Capecitabine and Bevacizumab. Six months post-surgery, a Positron Emission Tomography (PET) scan showed no signs of residual tumor or lymphadenopathy. Two years after surgery, the patient remains in remission, demonstrating the success of the treatment strategy.

A Promising Path Forward

This case underscores the potential of combining wide excision and reconstructive surgery with adjuvant chemotherapy to effectively manage recurrent sweat gland umbilical adenocarcinoma. The aggressive surgical approach, coupled with systemic therapy, offers a chance at long-term remission and improved quality of life for patients facing this rare and challenging condition.
