Value of imaging and aspiration cytology in the diagnosis of oncocytic carcinoma

Oncocytic carcinoma of the parotid gland is a rare neoplasm. To date 70 cases have been described in 55 reports. To the best of our knowledge the simultaneous occurrence of oncocytic carcinoma and second malignancy in another site (outside the parotid gland) has not been reported. An oncocytic carcinoma of the parotid gland is described in 56-year-old male with simultaneous breast cancer, emphasising the value of aspiration cytology and imaging procedures in the diagnosis of parotideal neoplasms

Small renal oncocytoma (≤4 cm): enhancement patterns on triphasic spiral computed tomography

In 18 patients with 19 RO, 9 hypervascularity and hypovascularity was identified in 9 and 10 RO, respectively, in the cortico-medullary phase (CMP). Hypervascular RO showed increased density in the CMP (151.438.5 HU) and a gradual wash-out in the nephrographic phase (133.834.6 HU) and excretory phase (7923 HU). Hypovascular RO showed increased density in the CMP (87.820.1 UH) and a gradual wash-out in the nephrographic phase (100.333 UH) and excretory phase (20.986.9 UH)

[Small renal oncocytoma (≤4 cm): enhancement patterns on triphasic spiral computed tomography].

Gli autori determinano criteri semeiologici qua- li-quantitativi per l’oncocitoma renale (OR) di piccole di- mensioni (≤4 cm) mediante TC trifasica. In 18 pazienti con 19 OR in fase cortico-midollare (FCM) le lesioni sono risultate ipervascolari (n=9) e ipovascolari (n=10). Gli OR ipervascolari hanno mostrato un incremento densitometrico in FCM (151,4±38,5 UH) ed un graduale wash-out in FN (133,8±34,6 UH) e in FP (79±23 UH). Gli OR ipovascolari hanno evidenziato un incremento densitome- trico in FCM (87,8±20,1 UH) ed un graduale wash-out in FN (100,3±33 UH) e in FP (86,9±20,9 UH)

[Role of CT in the preoperative diagnosis of a giant benign solitary fibrous tumor of the pleura].

Gli autori sottolineano il ruolo della TC nella dia- gnosi preoperatoria di un tumore gigante benigno solita- rio della pleura. La TC può stabilire la possibilità di comple- ta resezione della lesione e mostrare un evidente pedun- colo. La citologia aspirativa non è un approccio diagnostico affidabile
