abstract = {This manuscript summarizes the first part of the
proceedings of the 2023 Dublin ISUP Consensus Conference
encompassing the best practice recommendations on the
pathology of neoplasms of urachal origin. The rationale for
convening this consensus conference was the lack of
structured and consented histopathologic recommendations in
these rare tumors. Consensus among the meeting participants
(n=80) was reached on the following statements: (1)
combination of gross, histologic, clinical and imaging
findings with exclusion of secondary tumor metastasis are to
be used in the diagnosis of urachal carcinoma; (2) the 2022
World Health Organization (WHO) separate criteria for the
diagnosis of urachal adenocarcinoma and for nonglandular
carcinoma should be applied; (3) specific elements are to be
evaluated and recorded in the gross examination of resection
specimens containing urachal tumors; (4) sampling
considerations for resection specimens containing urachal
tumors are advised; (5) participants are against using $5\%$
or $10\%$ cutoff for the extent of intraepithelial carcinoma
in urachal mucinous cystic tumor of low malignant potential;
(6) use of immunohistochemical markers for the differential
diagnosis of urachal adenocarcinomas in transurethral
resection (TUR) specimen is considered optional; (7) similar
tumor classificatory (nosology) rules for carcinomas arising
from bladder mucosa (eg, urothelial carcinoma, squamous cell
carcinoma, and neuroendocrine carcinoma) should be applied
for nonglandular urachal carcinomas; (8) a new staging
approach other than the previously proposed systems should
be designed for urachal carcinoma; (9) a system modifying
the current Tumor-Node-Metastasis (TNM)/American Joint
Committee on Cancer (AJCC) staging system for urinary
bladder cancer is considered appropriate for a study in
urachal carcinoma; and (10) several histologic elements are
to be reported when diagnosing urachal carcinoma in TUR and
resection specimens. This report from the Dublin ISUP
consensus conference will serve as a practice recommendation
for pathologists and as a guide for future standardized
reporting protocols and research regarding urachal tumors.
In addition, an international database for urachal cancers
under the guidance of ISUP is being planned to be
established to address pertinent issues in the pathology of
urachal cancers.},
