Classic Kaposi's sarcoma: a case report.

A 60-year-old male from the Mediterranean area presented with edematous right leg and livid nodules and macules on the skin of upper and lower extremities. Biopsy specimen obtained from the right upper leg showed a pathohistologic finding indicative of Kaposi's sarcoma. Polymerase chain reaction testing revealed HHV-8 in the skin lesion. Serology for HIV was negative. Additional examinations did not reveal dissemination of the disease. Negative HIV serology, normal laboratory findings and absence of immunosuppressant therapy in the patient's history confirmed the diagnosis of the classic form of Kaposi's sarcoma.

Duplex-Doppler ultrasonography in the detection of lower extremities deep venous thrombosis and in the detection of alternative findings.

The diagnoses observed in patients referred for the Doppler ultrasonographic examination of peripheral and iliac veins for suspected deep venous thrombosis (DVT) are presented in this study. During 48 months 2,610 patients were examined by duplex Doppler ultrasonography (US). Among these, 1,879 were women (72%) and 731 men (28%), with the age-range 16-91 (mean 56, 2) years. Ultrasonic scanners Acuson 128 XP 10, ATL HDI 5000, GE Logiq 7, and GE Logiq 9 were used, with transducers in the frequency range from 2.5-14 MHz. Findings were categorized into four main categories: (1) deep venous thrombosis (DVT); (2) pathology predominantly related to superficial veins without DVT, (3) pathology of adjacent structures; (4) normal findings. 562 patients had DVT (21.5%). 1,108 patients (42.5%) had predominant pathology of superficial veins: postthrombotic syndrome, superficial thrombophlebitis and varicose veins. 390 patients (14.9%) had pathology of surrounding structures, unrelated to veins, the most common pathology being popliteal cysts and muscular hematomas. These lesions must be properly diagnosed by US to avoid erroneous anticoagulant treatment.
