PURPOSE: The differentiation between renal cell carcinoma(RCC) and transitional cell carcinoma(TCC) is important due to the different methods of treatment and prognosis. But occasionally it is difficult to draw a distinction between the two diseases when renal parenchyme and renal collecting systems are invaded simultaneously. MATERIAL AND METHOD: We reviewed CT scans of 37 cases of renal cell carcinoma and 12 cases of transitional cell carcinoma which showed involvement of renal parenchyma and renal sinus fat on CT. Retrospective analysis was performed by 3 abdominal radiologists. Check points were renalcontour bulging or reniform shape, location of mass center, intact parenchyme overlying the tumor, cystic change, calcification, LN metastasis, vessel invasion, and perirenal extention. RESULT:There were renal contour bulging due to the tumor mass in 33 out of 37 cases of renal cellcarcinima, wherea and nine of 12 cases of transitional cell carcinoma maintained the reniform appearance. This is significant statiscal difference between the two(p<0.005). Center of all TCCs were located in the renal sinus, and 24 out of 35 cases of RCC were located in the cortex(p<0.005). Thirty-six out of 37 cases of RCC lost the overlying parenchyma, whereas 4 out of 9 cases of well enhanced TCC had intact overlying parenchyma(p<0.005) RCC showed uptic change within the tumor mags in 31 cases which was significanity higher than the 4 cases in TCC(p<0.05). CONCLUSION: CT findings of renal cell carcinoma are contour bulging, peripheral location, obliteration of parenchyma, and cystic change. Findings of transitional cell carcinoma are reniform appearance, central location within the kidney, intact overlying parenchyma, and rare cystic change.

Cutaneous angiosarcorriias occur most commonly on the face and scalp of elderly individuals and are characterized by poor prognosis. We present a case of angiosarcoma in a 17-year-old boy not associated with any predisposing factors. The patient had three, ill-defined, 3 to 5 cm sized, erythematous, indurated subcutaneous nodules on the right upper extremity with a duration of 3 months. On histological examination, there were extravasated erythrocytes and irregular vascular channels lined by atypical endothelial cells in the dermis and subcutaneous tissue. The tumor cells appeared to dissect the collagen bundles. The patient was treated by wide surgical excision and post operative radiation therapy. However, 16 months after the operation, local recurrence was found to involve the close areas to the excision site on the right upper extremity and right axillary lymph nodes.

Higenamine is known to possess stimulatory activity on beta-receptor of the heart. Chronotropic actions of higenamic were studied in spontaneously beating right atrial muscle isolated from rabbits. The frequency of spontaneous beating and the relative threshold voltage of the right atrium were examined. The relative threshold voltage was defined as the minimal voltage of the given impulse above which the right atrium could be paced at the frequency of 20% of higenamine was also observed. Higenamine caused the postive chronotropic effect. This response became prominent as the ca2+ concentration in the bathing solution lowered. When tetrodotoxin was added to the bathing solution, the effect of higenemine altered and became similar to that of epinephrine. Higenamine reduced the relative threshold voltage of the right atrium in the bathing solution with [ca2+] of 0.5mM. Such effect was abolished by tetrodotoxin. The effects of verapamill on the spontaneous rate and the relativel threshold voltage were inhibited by higenemine. The above results suggest that, aithough the main action og higenamine is on the Ca channel, higenamine also have a minor effect of augmenting the Na channel.
