Transperineal core-needle biopsy of a rectal subepithelial lesion guided by endorectal ultrasound after contrast-enhanced ultrasound: A case report.

World J Gastroenterol 2021 Apr;27(13):1354-1361

Department of Gastroenterology, West China Hospital, Sichuan University, Chengdu 610041, Sichuan Province, China.

Background: Rectal subepithelial lesions (SELs) are commonly seen in endoscopic examination, generally manifested as bumps with a smooth surface. Precise preoperative diagnoses for rectal SELs are difficult because abnormal tissues are not easily to be obtained by regular endoscopic forceps biopsy. Traditional guidance modalities of preoperative biopsy, including endoscopic ultrasound, computed tomography, and transabdominal ultrasound, are often unsatisfactory. Read More

Prostate carcinomas mimicking a digestive malignancy.

Rom J Morphol Embryol 2020 Jul-Sep;61(3):751-758

Discipline of Morphopathology, Department of Microscopic Morphology, Victor Babeş University of Medicine and Pharmacy, Timişoara, Romania; e-mail:

Aim: To report our experience with specific cases of prostate cancer (PC) in which patients presented digestive symptoms, cases that represent a challenge and a source of error regarding the clinical and morphological diagnosis.

Methods: The most important clinical and pathological data were collected from three patients with PC which presented symptoms and/or investigations that initially suggested a digestive malignant tumor.

Results: We identified three patients with PC where the prostate tumor was not suspected based on the clinical-imagistic data, the correct diagnosis being the prerogative of the morphological investigation: in the first case, PC was detected during the microscopic examination of the lymph nodes (LN) in the intestinal resection specimen performed for suspected rectal cancer (RC), in the second case, in which the PC was synchronous with a RC, the dominant symptomatology was gastrointestinal, and in the third case, initially, the patient presented a widely disseminated PC, with pleural and bone metastases, as well as LN metastases, and apparent peritoneal involvement.

Prospective Validation of Pentraxin-3 as a Novel Serum Biomarker to Predict the Risk of Prostate Cancer in Patients Scheduled for Prostate Biopsy.

Cancers (Basel) 2021 Mar 31;13(7). Epub 2021 Mar 31.

Department of Urology and Organ Transplantation, University of Foggia, 71122 Foggia, Italy.

Arch Ital Urol Androl 2021 Mar 22;93(1):92-100. Epub 2021 Mar 22.

Division of Urology, School of Medicine, Università Politecnica delle Marche, Ancona.

Reasons why significant prostate cancer is still missed in early stage were investigated at the 22nd National SIEUN (Italian Society of integrated diagnostic in Urology, Andrology, Nephrology) congress took place from 30th November to 1st December 2020, in virtual modality. Even if multiparametric magnetic resonance (MR) has been introduced in the clinical practice several, limitations are emerging in patient with regular digital rectal examination (DRE) and serum prostate specific antigen (PSA) levels approaching the normal limits. The present paper summarizes highlights observed in those cases where significant prostate cancer may be missed by PSA or imaging and DRE. Read More
