1/79. Waxing and waning gynecomastia: an indication of noncompliant use of prescribed medication.We present two cases of recurrent gynecomastia in men enrolled in a placebo-controlled trial evaluating the efficacy of finasteride in treating benign prostatic hyperplasia. When the pharmacologic records were examined, it was apparent that the breast tissue hyperplasia diminished when the patients become noncompliant with their study medication and then resumed therapy. Because of the difficulty in obtaining accurate data on an individual's ability to maintain a consistent pharmacologic regimen, we believe that observing such "waxing and waning gynecomastia" may provide the physician with a clue regarding a patient's actual compliance with certain medications.- - - - - - - - - - ranking = 1keywords = hyperplasia (Clic here for more details about this article) |

Penile necrosis: an unexpected complication following transurethral resection of the prostate.A 69-year-old man who had undergone a transurethral resection of the prostate for benign prostatic hyperplasia developed necrosis of the glans penis following traction of the urethral catheter- - - - - - - - - - ranking = 0.5keywords = hyperplasia (Clic here for more details about this article) |
3/79. A monthly period of symptoms associated with benign prostatic hyperplasia.The number of times that a man with benign prostatic hyperplasia awoke each night with the urge to urinate (nocturia) was analyzed for randomness by Bartlett's Kolmogorov-Smirnov white noise test and for a periodic component by fourier analysis. The data series (n = 1549) was not white noise; it had a peak periodic component of 25 days, with a range of 21 to 37 days. The possibility that the monthly period of nocturia is a general phenomenon and is coupled to a monthly menstrual period, and the implications for more accurate diagnosis and new modes of therapy, are discussed.- - - - - - - - - - ranking = 2.5keywords = hyperplasia (Clic here for more details about this article) |
4/79. Transperineal magnetic resonance image guided prostate biopsy.PURPOSE: We report the findings of a transperineal magnetic resonance image (MRI) guided biopsy of the prostate in a man with increasing prostate specific antigen who was not a candidate for a transrectal ultrasound guided biopsy. MATERIALS AND methods: Using an open configuration 0.5 Tesla MRI scanner and pelvic coil, a random sextant sample was obtained under real time MRI guidance from the peripheral zone of the prostate gland as well as a single core from each MRI defined lesion. The patient had previously undergone proctocolectomy for ulcerative colitis and, therefore, was not a candidate for transrectal ultrasound guided biopsy. Prior attempts to make the diagnosis of prostate cancer using a transurethral approach were unsuccessful. RESULTS: The random sextant samples contained benign prostatic hyperplasia, whereas Gleason grade 3 3 = 6 adenocarcinoma was confirmed in 15% and 25% of the 2 cores obtained from the MRI targeted specimens of 2 defined lesions. The procedure was well tolerated by the patient. CONCLUSIONS: Transperineal MRI guided biopsy is a new technique that may be useful in detecting prostate cancer in men with increasing prostate specific antigen who are not candidates for transrectal ultrasound guided biopsy.- - - - - - - - - - ranking = 0.5keywords = hyperplasia (Clic here for more details about this article) |
5/79. Inferior vena cava compression due to massive hydronephrosis from bladder outlet obstruction.A 71-year-old man presented with acute urinary retention due to benign prostatic hyperplasia and was found to have computed tomography-documented mechanical obstruction of the inferior vena cava (IVC) due to massive hydronephrosis. Obstruction of IVC flow promptly resolved after bladder decompression.- - - - - - - - - - ranking = 0.5keywords = hyperplasia (Clic here for more details about this article) |
6/79. Unusual retrovesical masses in men.Retrovesical masses in men not related to prostatic carcinoma or hyperplasia is an uncommon pathology. Rare masses or unusual manifestations of those common diseases are a diagnostic dilemma. We review our experience in three unusual retrovesical masses in men: carcinosarcoma filling a giant bladder diverticulum; cystic prostatic carcinoma; and acquired cystic dilatation of the seminal vesicle associated with a prostatic carcinoma that obstructed and invaded the vesicle. We report the imaging findings and review the literature. In our experience, the imaging findings are usually not specific for doing a precise diagnosis and biopsy procedures are necessary.- - - - - - - - - - ranking = 0.5keywords = hyperplasia (Clic here for more details about this article) |
7/79. diagnosis of retrovesical ectopic and hyperplastic prostate tissue by transrectal needle biopsy.We report on an ectopic prostate in a 50-year-old man. Transabdominal ultrasonography, pelvic computed tomography, and pelvic magnetic resonance imaging revealed a heterogeneous tumor 8 cm in diameter in contact with the posterior wall of the urinary bladder. The tumor was histologically confirmed to be a benign prostatic hyperplasia. This is the 3rd case of retrovesical ectopic prostatic tissue which was diagnosed by transrectal needle biopsy.- - - - - - - - - - ranking = 0.5keywords = hyperplasia (Clic here for more details about this article) |
8/79. Dyspnoea and hyperventilation induced by synthetic progesterone chlorpromadinone acetate for the treatment of prostatic hypertrophy.We describe a 74-year-old patient with dyspnoea and tachypnoea induced by chlorpromadinone acetate, a synthetic progesterone used to treat prostatic hyperplasia. The dyspnoea, tachypnoea and hypocapnia improved after discontinuing the chlorpromadinone acetate. It is important to recognize that synthetic progesterones can cause dyspnoea and hyperventilation.- - - - - - - - - - ranking = 0.5keywords = hyperplasia (Clic here for more details about this article) |
9/79. Acute renal failure directly caused by hemolysis associated with transurethral resection of the prostate.Transurethral resection of the prostate (TURP) for the treatment of benign prostatic hyperplasia may lead to TURP syndrome, and in some cases, acute renal failure can develop. hemolysis does happen during TURP. Whether hemolysis itself leads to acute renal failure merits discussion. We report a patient with chronic renal insufficiency who developed oliguric acute renal failure immediately as a major complication after TURP. The renal function of this patient recovered after six hemodialysis sessions, and the patient continued to do well in the subsequent follow-up period.- - - - - - - - - - ranking = 0.5keywords = hyperplasia (Clic here for more details about this article) |
10/79. Exaggerated signet-ring cell change in stromal nodule of prostate: a pseudoneoplastic proliferation.A stromal nodule of the prostate was incidentally identified in a simple prostatectomy specimen from a 66-year-old man with benign prostatic hyperplasia. Microscopically, the nodule consisted of short spindly cells with bland nuclear features. Many of the cells in the nodule, however, contained a large, clear cytoplasmic vacuole that displaced and indented the nucleus, generating signet-ring cell morphology. Immunohistochemically, these cells were strongly positive for vimentin and weakly positive for desmin, suggesting a myofibroblastic nature. Further immunostains demonstrated the cells to be negative for cytokeratins and prostate-specific antigen, excluding the possibility of signet-ring cell carcinoma. The cytoplasmic vacuoles also stained negative for mucin production. Electron microscopy revealed no intracytoplasmic lumina. Notably, thermal effect or other signs of cellular injury, frequently associated with signet-ring cell change seen in prostate specimens obtained by transurethral resection and needle biopsy, were not appreciated in this stromal nodule. This case demonstrates that signet-ring cell change may occur in benign, hyperplastic, prostatic stromal cells in the absence of cellular damage.- - - - - - - - - - ranking = 0.5keywords = hyperplasia (Clic here for more details about this article) |
