Insights
This case study presents the first documented instance of a primary carcinoid tumor originating in the umbilicus. The patient successfully recovered after surgical resection and adjuvant therapies for metastatic carcinoid cancer.
Area of Science:
- Oncology
- Gastroenterology
- Surgical Pathology
Background:
- Carcinoid tumors are rare neuroendocrine neoplasms.
- Umbilical tumors are uncommon, with varied etiologies.
- Metastatic disease requires comprehensive treatment strategies.
Observation:
- A 78-year-old male presented with inguinal lymphadenopathy and an abdominal wall tumor.
- History of an untreated umbilical tumor and chronic diarrhea three years prior.
- Biopsy confirmed carcinoid metastasis.
Findings:
- Radical resection of the abdominal wall tumor, lymphadenectomy, and right hemicolectomy were performed.
- Malignant villous adenoma of the right colon was identified.
- Adjuvant therapy included alpha-interferon and longastatin.
Implications:
- This case represents the first reported instance of a primary umbilical carcinoid tumor.
- Highlights the importance of thorough histopathological examination for umbilical lesions.
- Successful management of metastatic carcinoid disease through combined surgical and adjuvant therapies.
Abstract:
A 78-year old male came to our observation presenting and enlargement of bilateral inguinal lymph nodes and a tumor of the mesogastric abdominal wall. Three years before the patient had been operated on for a primary tumor of the umbilicus with concomitant longstanding diarrhea. No histological examination was performed at that time. We performed a lymph node biopsy which demonstrated carcinoid metastasis. We went on to perform radical resection of the abdominal wall, regional lymphadenectomy and right hemicolectomy for malignant villous adenoma of the right colon. The abdominal defect was repaired by using Goretex mesh. Cyclic adjuvant alpha-interferon therapy was continued for more than 1 year, followed by long term therapy with longastatin. Twenty months after the operation the patient is in good clinical conditions and disease-free. On the basis of literature review our case appears to be the first primary carcinoid of the umbilicus.
