A Retropubic Cartilaginous Cyst in a Context of Surgery for Prostate Cancer.

Teaching Point: Retropubic cartilaginous cysts are rare, benign lesions originating from the symphysis pubis that should be considered in the differential diagnosis of a small slow-growing retropubic nodule.

Clinical Importance of Histopathological Inflammation in Patients with Lower Urinary Tract Symptoms Due to Benign Prostatic Hyperplasia: A Prospective Study of 222 Patients.

OBJECTIVE: To investigate the relationship between the severity of histopathological prostatic inflammation with lower urinary tract symptoms and prostate specific antigen (PSA) levels. METHODS: We prospectively included 222 consecutive patients eligible for transurethral resection of the prostate in a non-academic referral center by a single surgeon. Patients with proven urinary tract infection or prostate cancer were excluded. Preoperative assessment included PSA levels, International Prostate Symptom Score (IPSS), mean peak flow, mean resected prostate weight and post-residual volume. Finally, the presence and severity of inflammation was determined histopathologically. RESULTS: Mean patient age was 69.1 ± 8.6 years with mean preoperative PSA levels of 4.7 ± 5.4 ng/mL and IPSS of 15.7 ± 6.9. Mean peak flow was 10.7 ± 6.5 ml/s and the mean resected prostate weight 39.4 ± 27.3 g. Positive correlations between PSA (log) and prostate weight (r = 0.54, p < 0.001) and between PSA (log) and active (r = 0.30, p < 0.0001) and chronic inflammation (r = 0.19, p = 0.005) were observed. No correlations were found between IPSS and PSA (log) (r = -0.14, p = 0.040) or between IPSS and active inflammation (p = 0.659) or chronic inflammation (p = 0.125). CONCLUSION: The study showed a weak correlation between PSA and the active or chronic inflammation. It also showed that there was no correlation between the active or chronic histopathological inflammation and IPSS.

Giant hepatic carcinoid: a rare tumor with a favorable prognosis.

Primary hepatic carcinoids are rare tumors that are often diagnosed at a locally advanced stage. Their primary nature can only be ascertained after thorough investigations and long-term follow-up to exclude another primary origin. As with secondary neuroendocrine liver tumors, surgical resection remains the mainstay of therapy. Despite their large size and often central location liver resection is often feasible, offering long-term survival and cure to most patients. In selected patients liver transplantation appears to be a good indication for tumors not amenable to liver resection. An aggressive surgical attitude is therefore warranted. We report a large and unusually fast-growing liver carcinoid that appeared only marginally resectable in a patient who remains free of disease four years after surgery.
