androgenic alopecia as a physiologic process and benign prostatic hyperplasia (bph) as a pathologic process in the older population are androgen-dependent processes influenced by 5-alpha reductase enzyme which converts testosterone to dihydrotestosterone. this cross sectional study was done to evaluate the relationship between androgenic alopecia and bph. 150 men older than 50 years old, who pr...

Background & objective:Primary pleural neoplasms are rare entities compared with the pleural involvement by metastatic carcinoma. The current study aimed at investigating the complete spectrum of pleural neoplasms and differentiating between them with the aid of immunohistochemistry (IHC). Methods: Consecutive pleu...

Polypoid mass in the prostatic urethra is uncommon, yet the disease entities are so heterogeneous that the spectrum ranges from congenital malformations, benign polyps, to various malignancies. Prostatic urethral polyp (PUP) is a rare benign overgrowth of prostatic parenchyma protruding into prostatic urethra, and correspondingly, prostatic ductal carcinoma is a rare carcinoma originated from t...

Prostatic-Specific Antigen (PSA) is a low-molecular weight glycoprotein, that is uniquely associated with prostatic tissue. It has considerable diagnostic specificity for prostatic disease. Concentrations of PSA in serum correlate well with the stage of disease, and response to treatment in patients with prostatic cancer. It is, therefore, a good tumor marker for prostatic cancer. However, it h...

background : insulin-like growth factor-1 can act in both an autocrine and paracrine manner to promote normal growth and malignant cellular proliferation. the importance of this factor as a major regulatory peptide has been established for cells, in vitro and in vivo. however, the role of serum insulin-like growth factor-1 levels in the etiology of benign prostatic hyperplasia and prostate canc...

PURPOSE We evaluated the accuracy of detrusor wall thickness and intravesical prostatic protrusion, and the association of each test to diagnose bladder prostatic obstruction in patients with lower urinary tract symptoms. MATERIALS AND METHODS We enrolled in the study 100 consecutive patients with lower urinary tract symptoms due to benign prostatic hyperplasia. Baseline parameters were Inter...

PURPOSE To describe and illustrate the prostatic arterial anatomy from human cadaveric specimens, highlighting implications for prostatic arterial embolization. MATERIALS AND METHODS Dissection of 18 male pelves from white adults 35-68 years old was performed in the anatomy laboratory. Arterial branches were identified according to standard dissection technique using a 20-diopter magnifying l...

synchronous cancer is referred to two or more histological distinct malignancies diagnosed during the same hospital admission. globally more than 1 million people get colorectal cancer yearly resulting in about 0.5 million deaths. vulvar cancer is the fourth most common gynecologic cancer (following the corpus uterine cancer, cancer of ovary and cervix) and comprises only 4 percent of malignanc...

Prostatic calculi often occur in middle-aged and old men. Prostatic calculi are usually classified as primary/endogenous stones or secondary/extrinsic stones. Endogenous stones are commonly caused by obstruction of the prostatic ducts around the enlarged prostate by benign prostatic hyperplasia (BPH) or by chronic inflammation. Extrinsic stones occur mainly around the urethra, because they are ...

Bilateral breast mass was found in a 71-year-old male who had been placed on estrogen therapy for stage D2 prostatic adenocarcinoma. Microscopically the mass contained adenocarcinoma morphologically similar to that of the prostate, but the differential diagnosis was impossible between metastatic prostatic carcinoma and primary breast carcinoma. Formalin-paraffin sections of both tumors were sta...
