Gunshot vaginal trauma.

Nonobstetric vaginal or vulva trauma is an extremely rare occurrence, with an incidence of < 0.2% of traumas. CT represents the gold standard in the diagnosis of gunshot lesions due to its ability to detect and stage injuries with very high sensitivity and specificity. A standardized protocol for penetrating trauma is still under debate for the use of intravenous contrast only or also rectal and oral contrast. Herein, we report a case of gunshot vaginal trauma in a 43-year-old patient presenting with vaginal bleeding. In our case, the protocol was "patient's tailored," the intravaginal selective use of air was administered due to symptoms (vaginal bleeding) and CT findings, this 2-step protocol increased diagnostic confidence and allow a correct and challenging diagnosis.

Iatrogenic superior vena cava syndrome with concomitant deep vein thrombosis of azygos and hemiazygos veins.

Iatrogenic superior vena cava syndrome (SVCs) represents an emergent diagnostic entity and its correlation with deep vein thrombosis is extremely rare. Recently, the increased use of indwelling lines, pacemakers and intracardiac devices has led to more cases of SVC syndrome also associated with a higher frequency of DVT. We report an unusual complication in a 74-year-old female, who has been undergoing hemodialysis via CVC for 14 years, who referred at our Emergency Department complaining of shortness of breath, headache, face and neck swelling. She underwent chest Computed Tomography Angiography (CTA), that showed a thrombus extending from the superior vena cava to the azygos and hemiazygos veins. Acute SVCs should be suspected in emergency settings in symptomatic patients with indwelling central lines, catheters and pacemakers. CTA represents an accurate and quick imaging modality for the diagnosis and the assessment of the extension of the thrombus.

Squamous cell carcinoma and pilonidal cyst disease.

AIM: Squamous cell carcinoma developed on a chronic pilonidal cyst. CASE REPORT: Authors describe the case of a squamous cell carcinoma developed on a chronic pilonidal cyst in a 63- years-old patient with a 43 years history of recurrent pilonidal sinus disease. RESULTS: The patient underwent incisional biopsy, staging with total body CT and, finally, radical surgery. After 30 months there were no evidence of recurrence. DISCUSSION: Pilonidal sinus disease is a common disease that affects especially male subjects, obese and with excess of body hair. The complications that arise most frequently are cellulitis, abscess formation and developments of recurrences. Malignant transformation appears rather rare and is reported in the literature with a percentage that goes from 0.02% to 0.1%. CONCLUSIONS: Authors recommend accurate inspection of the pilonidal area in all chronic and longstanding inflammatory lesions and possibly practice incisional biopsies to exclude malignant degeneration.
