Endoscopic ultrasound-guided fine-needle biopsy in patients with unexplained diffuse gastrointestinal wall thickening.

Endosc Int Open 2021 Oct 16;9(10):E1466-E1471. Epub 2021 Sep 16.

Endoscopy Department, Hospital Universitario Río Hortega, Valladolid, Spain.

Endoscopic ultrasound-guided fine needle biopsy (EUS-FNB) is recommended after non-diagnostic biopsy in gastrointestinal wall thickening, although the performance of currently available FNB needles in this setting is unknown. We aimed to assess the diagnostic accuracy and safety of EUS-FNB and to evaluate the "T" wall staging in malignant pathology. This was a single center retrospective study that included all consecutive patients undergoing EUS-FNB for diffuse gastrointestinal wall thickening with at least one previous negative conventional endoscopic biopsy between January 2016 and November 2019.

Pleomorphic liposarcoma with liver metastasis diagnosed by combined fine-needle aspiration cytology and core-needle biopsy.

Diagn Cytopathol 2021 Sep 15. Epub 2021 Sep 15.

Department of Medicine and Surgery, University of Salerno, Salerno, Italy.

Pleomorphic liposarcoma (PLPS) is the rarest liposarcoma subtype, with high-local recurrence and metastasis rates. Fine-needle aspiration cytology (FNAC) is successfully used in the diagnosis of primary or metastatic soft tissue tumors, but liver metastases of PLPS diagnosed by FNAC have never been reported. The cytological diagnosis depends on the identification of lipoblasts with sharply defined cytoplasmic vacuoles indenting and distorting the nucleus in the context of a pleomorphic tumor and in a proper clinical and imaging context.
