Surgical resection to achieve tumor-free margins resulted in durable relapse-free survival of patients with intra-epidermal extramammary Paget's disease alone. Extramammary Paget's disease with invasion was associated with regional metastatic progression. The latter scenario as well as failure to treat localized extramammary Paget's disease alone was associated with a fatal outcome. Systemic chemotherapy should be further explored in patients with invasive adenocarcinoma or lymph node positive disease.

Our results showed a fourfold increased prevalence of asymptomatic renal stone disease in patients with surgically proven primary hyperparathyroidism compared with subjects not affected by the disorder. The National Institutes of Health consensus conference on asymptomatic primary hyperparathyroidism recommended that patients with renal stone disease undergo parathyroid surgery. These patients should undergo surgery even if they have minimal or no elevation of the total serum calcium value and no other metabolic manifestations of hyperparathyroidism. The finding of nephrocalcinosis or nephrolithiasis is, therefore, a significant finding in evaluating patients for parathyroid surgery. Routine imaging of the kidneys is necessary when primary hyperparathyroidism is documented.

The purpose of this work is to question the conventional theory that all pulmonary emboli (PE) are abnormal, and to test the hypothesis that small peripheral PE are a function of life. Most radiologists report any filling defect, independent of size, as clinically significant PE when detected in the pulmonary arteries. We sought to reinforce the theory that small dots in the pulmonary arteries are not clinically significant clots in the conventional setting. The necessity for anticoagulation should be balanced against the risk of bleeding. This retrospective HIPAA-compliant study was approved by the institutional review board; informed consent was not required. All patients diagnosed with PE by 16-slice or 64-slice multidetector computed tomography (CT) over a 6-month period who also had a lower extremity venous ultrasound (US) performed within 7 days of CT were identified. The study group included 26 women and 24 men (mean, 56 years; range, 21-90 years). The locations of the PE were plotted on a pulmonary arterial diagram, and width of the most proximal clot for each patient was measured. Of 1,273 consecutive CT studies, 101 were positive (7.9%) and 50 patients underwent lower extremity US. Thirty-three (66%) patients had PE in the central pulmonary arteries, of which 19 (58%) had deep vein thrombosis (DVT). Seventeen (34%) patients had peripheral PE; DVT was detected in 0 (0%) patients. The peripheral clots measured 1.0-3.8 mm (mean, 2.5 mm). These clots appeared focal and rounded with a "dot-like" appearance. Peripheral, focal filling defects in the pulmonary arteries, which we termed "dots," are not traditional embolic clots, are not associated with detectable lower-extremity clot load, and may represent "normal" embolic activity originating from the lower extremity venous valves. We suggest that more in-depth understanding about small peripheral PE is needed. The necessity of conventional anticoagulation should be critically reviewed in patients with subsegmental PE and minimal clot burden.
