Prostate-Specific Antigen Density: A Measurement to Differentiate Benign Hypertrophy of Prostate from Prostate Carcinoma.

 Determination of isolated prostate-specific antigen (PSA) in asymptomatic individuals has not demonstrated sufficient sensitivity and specificity to be useful in the routine evaluation of prostate disease. To enhance the accuracy of serum PSA we have used a proportion of serum PSA and prostate volume, which we refer to as prostate-specific antigen density (PSAD). Prostate volume in this study was calculated using transrectal ultrasonography (TRUS).

Primary urinary bladder mucosa associated lymphoid tissue type lymphoma presenting as a close mimic for genitourinary tuberculosis: Case report and review of literature.

Primary lymphoma of the urinary bladder is a rare entity. It has a distinctively different presentation than the urothelial carcinoma, which is the most common form of bladder cancer, but might mimic inflammatory lesions such as tubercular cystitis, clinically as well as radiologically. We present a case of primary extranodal marginal zone lymphoma of the bladder, which was a close mimicker of tuberculosis, leading to delay in diagnosis.

Lymphoepithelioma-like carcinoma of the urinary bladder: A rare case report.

Bladder cancers are the second most common urogenital malignancy, its most common type being urothelial carcinoma. Lymphoepithelioma-like carcinoma (LELC) which is commonly described in the nasopharynx is a very rare presentation in the bladder. Diagnosis of this entity poses a histopathological challenge.

Sub-cutaneous abscess caused by Nocardia asteroides in renal transplant recipient.

Nocardia is a significant opportunistic pathogen in patients with compromised immunity. Nocardia asteroides was isolated from subcutaneous abscesses on the left thigh and shoulder of a renal transplant recipient. Direct examination of the aspirated pus showed branching filaments that were gram-positive and acid fast.
