p63-expressing prostate adenocarcinoma
Prostatic adenocarcinoma with aberrant diffuse expression of p63 (p63-PCa) is a recently described variant of prostatic adenocarcinoma. (#23774168#, #18300803#)
p63-PCa can show a distinctive morphology consisting of atrophic, poorly formed glands, with multilayered and often spindled nuclei.
It is recommended that these tumors not be assigned a Gleason score and their favorable findings at RP be noted.
In a study of 8 cases [#18300803#], the (...)
prostatic glandular proliferation
18 March 2016

glandular proliferations in the prostate
A variety of small acinar lesions of the prostate can mimic prostate cancer in punch biopsies and in transurethral resection material.
Differential diagnostic problems are seen in the central and transition zone, including:
atypical adenomatous hyperplasia of the prostate,
atrophic processes,
sclerosing adenosis,
basal cell hyperplasia,
low-grade adenocarcinoma.
Differential diagnostic problems also occur in the peripheral zone (...)
prostatic calcifications
18 March 2016

Calcifications in prostate and ejaculatory system
Although calcifications in the prostate are a common manifestation, the relationship between calcifications and prostate cancer is not clearly documented as in breast cancer.
Calcifications are a very common finding in prostatectomy specimens and seem mostly to be associated with benign prostatic hyperplasia.
However, calcifications can occur in direct association with prostatic adenocarcinoma, although the incidence of this association (...)

central zone glands of the prostate
Definition: The central zone (CZ) is located at the base of the prostate adjacent to the seminal vesicles. Its histology can be potential mimicker of high-grade prostatic intraepithelial neoplasia (PIN).

prostate carcinoma with neuroendocrine differentiation

prostate cancer with neuroendocrine differentiation
On July 31, 2013, the Prostate Cancer Foundation assembled a working committee on the molecular biology and pathologic classification of neuroendocrine (NE) differentiation in prostate cancer. New clinical and molecular data emerging from prostate cancers treated by contemporary androgen deprivation therapies, as well as primary lesions, have highlighted the need for refinement of diagnostic terminology to encompass the full spectrum of (...)
