Silk suture granuloma with false-positive findings on PET/CT accompanied by peritoneal metastasis after colon cancer surgery

View Article: PubMed Central - PubMed

ABSTRACT

Suture granuloma is relatively rare.

After tumor resection, positive PET/CT findings could indicate suture granuloma.

Postoperative PET/CT surveillance might give false-positive findings.

PET/CT cannot detect small peritoneal metastatic lesions.

A surgical examination should be performed when metastases are suspected.

Gross tumor and histological findings.(a and b) The cut surface of the tumor, measuring 15 × 11 × 12 mm, was yellowish-white. (b) A histopathologic examination revealed a suture fragment at the center of the tumor (arrows) and necrotic tissue around it. Numerous atypical multinucleated giant cells surrounded the foreign body with massive polymorphonuclear cell infiltration.

Mentions: Peritoneal metastatic recurrence to the liver surface was suspected and surgery was performed. He underwent a partial hepatectomy (S5/S8) and partial resection of diaphragm. In addition, white nodules were detected in the Douglas pouch, which were diagnosed intra-operatively as adenocarcinoma by frozen section analysis. A pathological examination after surgery showed that the liver tumor was not malignant and was actually a foreign body granuloma with silk suture inclusions (Fig. 2).
