ABSTRACT
CONTEXT Primary adenocarcinomas of the bladder are uncommon and usually occur by contiguity with or hematogenic dissemination of other adenocarcinomas such as colorectal, prostate and gynecological tract carcinomas. Mucinous and signet-ring cell histological patterns are even rarer and it is often difficult to morphologically distinguish them from metastatic colorectal adenocarcinoma. CASE REPORT We present and discuss a rare case of primary mucinous adenocarcinoma of the bladder with signet-ring cells in a 57-year-old male patient. Other primary sites for the tumor had been excluded and, in the absence of digestive tract tumor and for confirmation that it was a primary bladder tumor, an immunohistochemistry study was performed.
RESUMO

CONTEXTO:

Adenocarcinomas vesicais primários são incomuns, o habitual é o comprometimento por contigüidade ou via hematogênica de outros adenocarcinomas como colorretal, próstata e trato ginecológico. O padrão histológico correspondente ao mucinoso e com células em anel de sinete é mais raro e, muitas vezes, há dificuldade em distingui-lo morfologicamente do adenocarcinoma colorretal metastático. RELATO DE CASO Apresentamos e discutimos um caso de adenocarcinama mucinoso com células em anel de sinete primário da bexiga em um paciente masculino, de 57 anos. Foram excluídos outros sítios primários do tumor e, na ausência de tumor do trato digestivo e para confirmação de tumor vesical primário realizou-se estudo imunoistoquímico.
