Prostate Cancer Nonascitic Peritoneal Carcinomatosis After Robot-assisted Laparoscopic Radical Prostatectomy: 3 Case Reports and Review of the Literature. Urology 2019; 137:121-125.

Abstract
Robot-assisted laparoscopic radical prostatectomy is one of the treatment options for localized prostate cancer, with an excellent disease control rate. However, these patients can experience late disease recurrence with metastatic dissemination. Peritoneal metastases are an uncommon recurrence site. Here, we discuss 3 cases of peritoneal metastases following robot-assisted laparoscopic radical prostatectomy and the mechanisms of peritoneal invasion. Through a literature review and our case reports, we postulate the existence of 2 distinct mechanisms of peritoneal invasion: one being iatrogenic, following a laparoscopic surgery with a well differentiated prostate cancer at a nonadvanced stage of the disease, the other involving the natural course of poor-prognosis tumors, even without surgery.

Abstract
In patients with prostate cancer, metastases mostly develop in bone, lung, liver, pleura and adrenal glands. Prostate carcinoma metastases to the ureter are very rare, and the peritoneum is an even rarer site of prostate metastases. We present two cases of ureteral metastases of prostate cancer, of which one patient also developed malignant ascites and peritoneal metastases. An overview of the literature on these metastatic sites is also provided. Both patients presented with hydronephrosis and a ureteral mass. Biopsies of the masses were taken, which showed the presence of prostate carcinoma metastases. The first patient was treated with chemotherapy but was diagnosed with progressive disease and died 3 years later. The second patient was diagnosed with pathology-confirmed peritoneal metastases 8 months later. He died 2 years after presentation with hydronephrosis.

Abstract
Malignant ascites from advanced prostate cancer is rare and has a poor prognosis. We report a case of a 57-year-old African American male presenting with weight loss, lower urinary tract symptoms and voiding dysfunction. He also had renal failure with metabolic abnormalities associated with significant abdominal distention and pain. Computed tomography showed ascites, which was pathologically confirmed by immunostaining and cytological identification of malignant cells. Prostate biopsy identified high-grade prostate cancer which responded to hormonal therapy with a significant decrease in serum prostatic-specific antigen. Ascites was managed with paracentesis and renal failure with hemodialysis as needed.

Abstract
Mucin-producing tumors of the prostate include both primary and secondary tumors with mucinous differentiation or features involving the prostate gland. These tumors are relatively rare and have variable prognostic and therapeutic implications. Primary mucinous (colloid) adenocarcinoma of the prostate is defined as prostatic adenocarcinoma with mucinous differentiation involving 25% or more of the entire tumor. Another primary tumor of the prostate that may have mucinous features is primary mucin-producing urothelial-type adenocarcinoma of the prostate (mucinous prostatic urethral adenocarcinoma). Primary mucin-producing urothelial-type adenocarcinoma of the prostate is a distinct entity that typically arises from the prostatic urethra possibly from urethritis glandularis or glandular metaplasia with malignant transformation, and it is analogous to adenocarcinoma with mucinous differentiation arising from the urinary bladder. Signet ring cell tumors of the prostate, though rare, may also have mucinous features. Secondary tumors with mucinous differentiation that may involve the prostate include adenocarcinomas of the urinary bladder and colorectum. Pathologists should also be aware of mucin-producing tumor-like lesions involving the prostate, including mucinous metaplasia, and benign Cowper glands that may mimic malignancy. Herein we present an updated and comprehensive review of the clinicopathologic, immunohistochemical, molecular, and prognostic features of mucinous tumors and tumor-like lesions involving the prostate gland, with emphasis on mucinous prostatic adenocarcinoma and its mimickers, including potential diagnostic pitfalls.

Abstract
Beyond the typical acinar morphology observed in the majority of prostatic adenocarcinomas, a spectrum of morphologic variants and prostate cancer subtypes exists. These unusual entities may be classified as: (1) cancer morphologies arising by divergent differentiation of prostatic ductal, acinar, or basal cells and associated with unique clinical features and/or therapeutic approaches, and (2) histologies occurring in the context of usual prostatic adenocarcinoma that may result in diagnostic misinterpretation or difficulties in Gleason grade assignment, especially in limited samples. This article details a number of variants, with emphasis on diagnostic criteria, differential diagnoses, and clinical significance.

Abstract
Omental metastasis with malignant ascites from prostatic adenocarcinoma is rare. This case report is about a patient who presented with a 24-hour history of a swollen right leg. Clinical examination revealed a hard prostate and blood biochemistry demonstrated an elevated prostate specific antigen level. A Doppler ultrasound scan excluded deep venous thrombosis, but a CT scan of the abdomen revealed marked para-aortic lymphadenopathy and prostate gland biopsy confirmed prostatic adenocarcinoma. The patient was treated with goserelin. Three years later, he presented with ascites and an omental mass. Histology of the omental mass showed metastasis from the prostatic adenocarcinoma. He was treated with second-line hormonal therapy but died after 4 months. We discuss the clinical progression, with a review of the literature.

Abstract
Nine patients treated with primary signet ring cell carcinoma of the prostate were identified among 29,783 cases of prostate cancer evaluated at Mayo Clinic from January 15, 1970, until January 2, 2009. A PubMed search of the English-language literature published from January 1, 1980, to January 1, 2010, was then performed using the key words signet ring cell and prostate, identifying 42 cases. This study reviews those cases, along with the additional 9 reported herein, and evaluates clinical characteristics, histologic diagnoses, treatment modalities, and outcomes. Mean age at diagnosis was 68 years (range, 50-85 years), and mean prostate-specific antigen level was 95.3 ng/mL (range, 1.9-536.0 ng/mL; to convert to μg/L, multiply by 1). Most patients (66%) had non-stage IV carcinoma, the most common Gleason sum was 8 (33%), and mean survival was 29 months. The presence of a primary signet ring cell carcinoma of the prostate was best confirmed by negative findings on gastrointestinal work-up, a positive stain for prostate-specific acid phosphatase, and negative carcinoembryonic antigen test results.

Abstract
BACKGROUND In the present study, we had the rare opportunity to study immunological responses of TAL from ascites fluid in a patient with hormone-refractory prostate cancer. METHODS We evaluated tumor antigen-specific T-cell responses, induced by either prostate specific antigen (PSA) pulsed dendritic cells (DCs) or PSA peptides, in TAL and peripheral blood lymphocytes. RESULTS DC stimulation with PSA protein induced recognition of naturally processed PSA epitopes by both blood and ascites T cells. In contrast, only ascites T cells recognized the PSA-3 peptide, after stimulation with PSA-pulsed DCs or peptides. Finally, although IFNgamma secreting T cells were detectable in both blood and ascites by ELISPOT, multiplex cytokine assay detected the presence of predominantly Th2 cytokines. CONCLUSIONS Although tumor antigen-specific TAL were detected in ascites fluid, these cells were producing immunosuppressive cytokines which may contribute to tumor escape from recognition and/or destruction by the immune system.

Abstract
Primary signet-ring cell carcinoma (SRCC) of the prostate is very rare and has a poor prognosis, even when treated with aggressive therapy. We report herein a case of a 72-year-old man with prostatic SRCC. The patient had a tumor that extended directly to the rectum. Maximal androgen blockade was started and 20 months later, the patient was alive without evidence of recurrence. The present case of prostatic SRCC responded well to medical therapy, however, tumors can recur after a long period of time. Therefore, adjuvant therapy is recommended.

Abstract
Signet-ring cell carcinoma (SRCC) of the prostate is a very rare neoplasm and there have been only 38 cases reported to date. Here the 39th case of prostatic SRCC containing a small amount of neutral mucin, prostatic specific antigen (PSA) and prostatic specific acid phosphatase (PSAP) in the signet-ring cells is reported. It was also found that some intracytoplasmic lumina were derived from the shallow or deep invagination of luminal membranes of cancer cells that formed the neoplastic glands. Using immunohistochemistry, a combination of monoclonal antibodies against cytokeratins 7 and 20 as well as PSA and PSAP may be useful in differentiating prostatic primary SRCC from metastatic SRCC originating in the gastrointestinal tract.

Abstract
High-grade prostatic intraepithelial neoplasia (HGPIN) is the most likely precursor proliferation of peripheral zone, moderately to poorly differentiated prostatic adenocarcinomas. The usual cell type of the epithelial lining of HGPIN is a glandular epithelial cell with characteristic nuclear abnormalities. Here we report nine cases of unusual types of HGPIN, including three cases of signet-ring cell HGPIN, one case of small cell neuroendocrine HGPIN, and five cases of HGPIN with distinctive mucinous features. The three examples of signet-ring cell PIN were all associated with an invasive primary signet-ring cell carcinoma of the prostate. The HGPIN assumed a classical tufted and micropapillary architectural growth pattern, with the constituent cells exhibiting a morphologic appearance identical to that of the invasive signet-ring cells. The intraepithelial and invasive signet-ring cells were mucin negative and were immunoreactive for prostate-specific antigen (PSA). A fourth case displayed a mixed intraepithelial glandular-small cell neoplastic proliferation, where intraepithelial small cells were histologically identical to surrounding invasive small cell carcinoma cells. The small cell HGPIN and invasive small cell carcinoma cells were positive for the neuroendocrine markers chromogranin, synaptophysin, and neuron-specific enolase. In five cases, mucinous distension of HGPIN glands, producing a flat pattern of the epithelial lining layer, comprised the third unusual pattern of HGPIN. These blue mucinous secretions were readily detected by hematoxylin and eosin staining and were composed of both neutral (periodic acid-Schiff-positive) and acidic (alcian blue-positive) mucins. Herein we document the existence of an intraepithelial proliferation of neoplastic cell types-small cell neuroendocrine and signet-ring cell-that are usually considered as stromal-invasive cells in the prostate. The presence of these rare prostatic cell types in both HGPIN and invasive carcinoma provides further support for a close relationship between HGPIN and invasive carcinoma of the prostate. All three unusual types of HGPIN-signet-ring cell, small cell neuroendocrine, and mucinous-are important to diagnostically recognize because of the strength of association of HGPIN with invasive carcinoma.

Abstract
A case of prostatic signet-ring adenocarcinoma is described in a man with a history of open prostatectomy for prostate carcinoma (18 years previously). Immunostaining confirmed the prostatic origin of the signet-ring tumor which stained for prostatic acid phosphatase (PSAP) and prostate specific antigen (PSA). Cytokeratin immunostaining showed the vacuoles to be true lamina with clear and distinct outlines, the feature confirmed by ultrastructural examination. This aggressive tumor is an uncommon but distinct variant of primary prostatic carcinoma which should be distinguished from artefactual vacuolation of tumor, inflammatory and stromal cells, and metastatic disease.

Abstract
It is generally believed that signet-ring cell carcinoma (SRCC) of the prostate is a high-grade neoplasm with a poor prognosis. We report a case of a long-term survivor diagnosed with localized prostatic SRCC (T3N0M0), who has been alive without any clinical evidence of disease for 100 months after combination therapy which consisted of local irradiation and hormone administration. A posttreatment needle biopsy confirmed the pathological complete response.

Abstract
We report an uncommon case of primary prostatic signet-ring cell carcinoma which meets all criteria that define this clinicopathologic entity. Histologically, the tumor showed three different growth patterns, all of which contained large numbers of signet-ring cells. The predominant pattern, comprising approximately 50 percent of the tumor, was solid sheets of pure signet-ring cells. An intriguing finding was the presence of intestinal metaplasia involving the prostatic urethra and the large periurethral ducts. All mucin stains were intensely positive within the signet-ring cells and in the mucin lakes. Signet-ring cells stained positively for prostatic specific antigen, prostatic acid phosphatase, and carcinoembryonic antigen immunoperoxidase markers. Our patient presented with symptoms of urinary tract obstruction and locally widespread disease, infiltrating the rectum and the bladder, thus demonstrating the aggressive biologic behavior that traditionally has been ascribed to signet-ring cell carcinomas.
