Extensive prostatic calculi in alkaptonuria: An unusual manifestation of rare disease.

Extensive prostatic calculi in a young man should always elicit the suspicion of alkaptonuria. Although prostatic calculi are seen in chronic prostatitis, chronic pelvic pain syndrome and benign prostate hyperplasia, none of these have prostatic calculi or calcification as extensive as in alkaptonuria. A 36 years young man who had severed obstructive lower urinary tract symptoms with extensive prostatic calculi was found to be alkaptonuric on further evaluation.

Elevated international normalized ratio associated with concomitant warfarin and erlotinib.

Purpose: The case of a patient who developed elevated International Normalized Ratio (INR) values after concomitant administration of warfarin and erlotinib is reported.

Summary: A 47-year-old Caucasian man with a history of atrial fibrillation, anxiety, and a 40-pack-year smoking history was diagnosed with advanced, moderately differentiated adenocarcinoma of the lung. Soon after being diagnosed with non-small-cell lung cancer, warfarin was initiated for the treatment of a venous thromboembolism.
