Transitional cell carcinoma of the ureter and struvite calculi

Context: The association of primary carcinoma of the ureter and lithiasis is extremely rare. We report a rare case of a primary carcinoma of the ureter with corariform calculus. Case Report: 60-year-old phaeodermal female, reported a history of right-side nephritic colic, hyperthermia and pyuria during the past 20 years andhad received treatment for urinary infections a number of times. The first clinical presentation was related to lithiasis and the tumor had not been shown up by excretory urography, cystoscopy or ultrasonography. Two months after the calculus had been eliminated, the patient began to have serious symptoms and a grade III transitional cell carcinoma of the ureter was discovered. Total nephroureterectomy and M.V.A.C. (Metrotrexate + Vinblastina + Doxo Rubicina + Cisplatina) chemotherapy were tried unsuccessfully. In this report we emphasize the diagnostic difficulty caused by the concomitant presence of the two pathologies. In our opinion, the rapid evolution in this case is directly related to the high grade of the tumor.

Penis wound by scorpion sting

The majority of scorpion stings are oligosymptomatic, occurring mainly on the hands and feet Fatality is rare. Case report: A 33-year old man suffered a severe sting on his penis from a scorpion of the species Tytius trivittatus. Alcohol and salt were used without success in an effort to relieve pain. Medical assistance was sought 4 hours after the event, at which time diffuse erythema, edema and punctiform injury on the glans penis were observed, with no systemic manifestation. Intravenous meperidine was administered with immediate relief of the pain. The local signs disappeared within 48 hours, with the patient remaining asymptomatic.
