Cutaneous invasion from sarcomatoid urothelial carcinoma: clinical and dermatopathologic features

Abstract In Brazil, without considering the non-melanoma skin tumors, bladder cancer in men is the eighth most common, and the urothelial carcinoma or transitional cell carcinoma is the most common among these. Cutaneous metastases from urothelial neoplasms appear as single or multiple erythematous, infiltrated nodules or plaques, and like other cases of distant disease, it is indicative of poor prognosis. The invasive urothelial carcinoma is recognized for its ability to present divergent differentiation and morphological variants. The sarcomatoid urothelial carcinoma is a rare cancer that consists of two different components: one composed of epithelial tissue and the other with sarcomatoid features of mesenchymal origin. The authors describe a case of cutaneous metastasis of sarcomatoid urothelial carcinoma in a 63-year-old male patient.

Insuficiência tricúspide severa por infarto do músculo papilar anterior do ventrículo direito secundário à hipóxia neonatal / Critical tricuspid insufficiency due to papillary muscle infarction of the right ventricle in a distressed newborn infant

Os autores relatam um caso fatal de insuficiência tricúspide severa observada no período neonatal, devida a infarto do músculo papilar anterior do ventrículo direito (VD), secundário à hipóxia. Logo após o nascimento o bebê necessitou de manobras de ressuscitaçäo e, ao exame do precórdio, havia sopro sistólico. O exame ecocardiográfico evidenciou falta de coaptaçäo do folheto anterior da válvula. O exame macroscópico do coraçäo revelou ruptura da corda tendínea entre os folhetos anterior e posterior e a microscopia mostrou, nesta área, necrose e depósito de cálcio. A anóxia no período perinatal, na maioria dos casos, leva a alteraçöes cardíacas transitórias, mas em alguns, pode ser fatal e, por isso, é importante a avaliaçäo cardiológica em todos os recém-nascidos com sofrimento prolongado

A fatal case of a stressed newborn baby who developed tricuspid insufficiency due to an anterior papillary muscle infarction of the right-ventricle, related to perinatal anoxia is reported. The baby needed resuscitation management and had a systolic murmur soon after birth. The echocardiographic examination showed aflail anterior leaflet of the tricuspid valve due to an avulsed anterior papillary muscle. There was rupture of chordae tendineae between anterior and posterior leaflet. Necrosis and calcinum deposit were found in the area. The conclusion was that the anoxia in perinatal period, in most cases, causes transient lesions, but infew cases might be severe and fatal. It is important a complete cardiac evaluation in every case of prolonged perinatal stress
