Sporadic Desmoid-Type Fibromatosis Occurring at Laparoscopic Trocar Site: An Unusual Entity
Open accessAbstract
Desmoid-type fibromatosis (DF) or desmoid tumours are rare benign soft tissue tumours of musculo-aponeurotic origin, which have no malignant potential but are locally aggressive and can result in significant morbidity. They may be hereditary (in association with FAP, i.e. familial adenomatous polyposis syndrome resulting from APC gene mutation) or sporadic, with hereditary cases having a much higher risk of developing DF compared to sporadic ones. Desmoids are known to occur in previous surgical scars. However, previous laparoscopic port site/trocar site is an extremely uncommon site for sporadic desmoids, with only two cases of sporadic laparoscopic trocar site desmoids (occurring in absence of FAP) reported in world literature. We thus describe a case of sporadic DF, occurring at the site of umbilical port 8 months following laparoscopic cholecystectomy for cholelithiasis, treated successfully by margin-negative resection. To the best of our knowledge, this appears to be the first such case in Indian literature and the first being reported after laparoscopic cholecystectomy. In the era of laparoscopic surgery, one must be aware of the existence of such an entity after laparoscopy as it may be confused with conditions such as metastatic deposit, port site tumour recurrence, port site hernia, scar site endometriosis, soft tissue sarcoma etc. and may result in diagnostic dilemma.

The Abstract and Case Presentation describe one case of sporadic desmoid-type fibromatosis at the umbilical port site, eight months after laparoscopic cholecystectomy. The claim's plural “cases” is not supported: Gupta et al. report a single such case. (LLM, conf=0.88)

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
