Squamous cell carcinoma (SCC) is a rare variant of prostate cancer. We report a case of a patient who was diagnosed with metastatic adenocarcinoma of the prostate, treated with leuprorelin and subsequently found to have SCC 18 months later. We have found one case in the literature with a similar scenario of possible transformation of adenocarcinoma to SCC secondary to luteinizing hormone-releas...
Small cell carcinoma of the prostate is a rare neoplasm, with only a few series hitherto reported. A little less than half of the cases are associated with conventional acinar adenocarcinoma, which are usually high grade. Although consensus has not been reached, the majority of patients with small cell neuroendocrine carcinoma of the prostate have advanced disease at diagnosis and disproportion...
The outer dense fiber (ODF) genes encode proteins that co-assemble along the axoneme of the sperm tail. Recently, it was demonstrated that some ODF genes are aberrantly expressed in tumors, including prostate adenocarcinoma, basal cell carcinoma, and chronic myeloid lymphoma. We cloned ODF3 and ODF4 cDNA from the testis of a patient suffering from prostate adenocarcinoma and found two alte...
INTRODUCTION We aim to present transperineal template-guided prostate biopsy (template biopsy) outcomes at a tertiary referral centre. Furthermore, to identify the detection rate of prostate cancer in those with a previous negative transrectal ultrasound guided prostate biopsy and the upgrade rate of those on active surveillance for Gleason 3 + 3 = 6 prostate adenocarcinoma. MATERIAL AND METH...
RATIONALE About 95% of prostate cancers are adenocarcinoamas. Depending on the detection method used, neuroendocrine cells are found in 10% to 100% of prostate cancer specimens. OBJECTIVE A 64-year-old patient was diagnosed in 2006 with adenocarcinoma of the prostate, PSA 4.1 ng/ml, Gleason 6, T3b, positive PSA immunohistochemistry. METHODS AND RESULTS The patient was started on hormone the...
The number of trinucleotide repeats [CAG (coding for polyglutamine), GGC (coding for polyglycine)] in the first exon of the androgen receptor (AR) gene and prostate-specific antigen (PSA) gene androgen response element I A/G polymorphism are both related to prostate cancer prognosis. We investigated whether these genomic changes occur in the AR and PSA genes, which are usually found in in...
Intraductal carcinoma of prostate has been previously described in radical prostatectomies. It's rarely encountered in needle biopsies in the absence of infiltrative carcinoma. But, both histogenesis and nomenclature of the lesion is still controversial. Among the pure intraductal carcinoma of prostate cases, a different solid patern was described with smaller nuclei at the center of the ducts....
Generalized lymphadenopathy is a rare manifestation of metastatic prostate cancer. Here, we report the case of a 59-year-old male patient with supraclavicular, mediastinal, hilar, and retroperitoneal and inguinal lymphadenopathy, which suggested the diagnosis of lymphoma. There were no urinary symptoms. A biopsy of the inguinal lymph node was compatible with adenocarcinoma, whose prostatic orig...
Adenocarcinoma of prostate metastasizing to testis is a rare occurrence and is incidentally detected in orchiectomy specimens. The pattern of metastasis may mimic a primary neoplasm of testis like a seminoma or lymphoma and pose a diagnostic difficulty for the pathologist. A rare case of bilateral testicular metastasis of prostatic adenocarcinoma is presented wherein the metastatic cells expres...
OBJECTIVES A subset of prostate carcinomas is composed predominantly, even exclusively, of neuroendocrine (NE) cells. In this report, we sought to characterize the gene expression profile of a prostate small cell NE carcinoma by assessing the diversity and abundance of transcripts in the LuCaP 49 prostate small cell carcinoma xenograft. METHODS We constructed a cDNA library (PRCA3) from the L...
