Embryonal rhabdomyosarcoma of the bladder is a tumor thar presents sporadically in the adult patient and its treatment continues to be a controversy. One such case is presented herein. The epidemiological and histopathological features of this tumor type are described and the different therapeutic approaches advocated in the literature are discussed.
Necrosing vasculitis and, within it, nodosa polyarteritis, is an infrequent entity characterized by the absence of pathognomonic signs and symptoms, but which can potentially affect the entire body. The initial description was made by Kussmaul and Maier in 1866. Sings and symptoms of this clinical picture are not frequently circumscribed to the urinary tract. We describe here one case of a particularly infrequent presentation, as a vesical mass with gross haematuria. The paper discusses the clinical picture, diagnosis and treatment of this process.
We record a case of an 18 year old female patient with a history of asymptomatic, keratotic, waxy papules localized over the thenar and hypothenar eminence of palms and the internal aspect of the soles of feet. Histologically they were characterized by hyperkeratosis, acanthosis, elastorrexis and enlarged collagen fibers, typical of the picture known as Costa's acrokeratoelastoidosis. We establish a differential diagnosis with other clinically similar keratotic conditions.
Twenty seven children were followed up prospectively after renal transplant for evidence of infection and illness due to cytomegalovirus (CMV), Epstein-Barr virus (EBV) and varicella zoster virus (VZV). Virus shedding and serological status were tested at transplant day, biweekly for two months, monthly for six months and trimestrialy thereafter. Determinations were done by complement fixation test. CMV isolation was established by microscopic examination of urinary cultures. Primary infections were objetivated in 27 cases (18 CMV, 1 EBV, 8 VZV) and reinfection in 3 (2 CMV, 1 VZV). Irreversible allograft rejection related to infection was disclosed in 2 patients (1 primary CMV infection, 1 VZV reinfection). Renal function impairment occurred only with CMV (6 primary and 1 secondary infections). One patient died with CMV over infection.

Middle ear neuroendocrine neoplasms are rare and of benign behaviour. Diagnosis is difficult since they produce non-specific symptoms. Electron microscopy and immunochemistry are necessary. We present a carcinoid tumor in a 28-year-old man with one side deafness. He underwent tympanoplasty, staying free of recurrences two years and a half later.
