Most prostate cancers (PCas) are classified as acinar type (conventional) adenocarcinoma which are composed of tumor cells with luminal differentiation including the expression of androgen receptor (AR) and prostate-specific antigen (PSA). There are also scattered neuroendocrine (NE) cells in every case of adenocarcinoma. The NE cells are quiesecent, do not express AR or PSA, and their function...

INTRODUCTION Chronic inflammation of longstanding duration has been linked to the development of carcinoma in several organ systems. It is controversial whether there is any relationship of inflammatory atrophy to prostate cancer. It has been suggested that the proliferative epithelium in inflammatory atrophy may progress to high-grade prostatic intraepithelial neoplasia and/or adenocarcinoma. ...

INTRODUCTION Prostatic metastasis from a primary bowel adenocarcinoma has been only rarely reported in the medical literature. The case reported here is rare in the fact that the primary tumor was from a right-sided bowel adenocarcinoma. It is unusual because initial immunostaining was not fully conclusive, and so a relatively new method of immunostaining, CDX2, was used to ascertain its histop...

Sarcomatoid carcinoma of the prostate is among the rarest malignant neoplasm types and has been well known for its aggressive clinical course. Patient was admitted with the symptoms of lower urinary tract. Transurethral resection of prostate (TUR-P) was carried out. Revealing Gleason 5 + 3 = 8 prostate adenocarcinoma in TUR-P material. Thereby, a Radical Prostatectomy procedure was planned. In ...

Docetaxel has been widely used in the treatment of several cancers, including adenocarcinoma of the prostate gland. As docetaxel is insoluble in water, it must be administered with polysorbate 80 and ethanol, which are known to cause hypersensitivity reactions. Premedication with corticosteroids and antihistamines is advocated prior to docetaxel administration; however, toxicities, occasionally...

INTRODUCTION The sign of Leser-Trélat is defined by the sudden appearance and rapid increase in number and size of seborrheic keratoses, preceding or revealing a malignancy. Even though this sign remains controversial, it has been described during a wide range of malignancies, including mainly adenocarcinoma of the gastro-intestinal tract or the breast. CASE PRESENTATION We report the case of...

Radiation therapy (RTx) has been employed as a curative therapy for prostatic adenocarcinoma. RTx-induced sarcomas (RISs) are rare, late adverse events, representing less than 0.2% of all irradiated patients. RISs are more aggressive tumors than prostatic adenocarcinomas. Herein, we present a case with RTx-induced prostatic leiomyosarcoma after permanent brachytherapy for prostatic adenocarcino...

Background The survival benefit of adjuvant radiotherapy (ART) in prostate adenocarcinoma, with limited numbers of pathologically involved lymph nodes (LNs) after radical prostatectomy (RP), is controversial. Materials and Methods From 2004 to 2014, data for prostate cancer patients categorized as N1M0 after RP were retrieved from the Surveillance, Epidemiology, and End Results (SEER) databas...

Prostatic ductal adenocarcinoma (PDA) is an uncommon histological variant of prostatic adenocarcinoma that may present clinically as a cystic mass [1-3]. We report a case of cystic PDA presenting as a cystic perirectal mass in a 61 year old male. Fine needle aspiration cytology showed malignant cells with round-oval to focally elongated nuclei, conspicuous nucleoli, and amphophilic cytoplasm wi...
