Mujer de 49 años con clínica urinaria de larga evolución. Estudio histológico e inmunohistoquímico de un caso de mullerianosis vesical

Bladder müllerianosis is defined by the presence of Müllerian epithelium (endometrial, endocervical or endosalpinx) in the bladder. It is a rare benign disease that affects women and presents a non-specific clinical presentation that poses a broad differential diagnosis. We present the case of a 49-year-old woman who presented with recurrent urinary tract infections, urinary discomfort and abdominal pain. The approach is carried out by ultrasound and urethrocystoscopy that reveal the presence of a 5 mm polypoid lesion that is removed. The histological study revealed bladder müllerianosis together with the complementary finding of glandular cystitis and cystic cystitis.
