Longitudinal ultrasound image of the bladder in a young child shows a solid excrescence arising from the posterior wall of the bladder. At resection, this was diagnosed as a papillary urothelial carcinoma. Bladder carcinoma is rare in children. The most common pediatric bladder neoplasm is rhabdomyosarcoma. Bladder carcinoma typically affects adults in their 70s and is more common in males. #TummyTuesday

Coronal (image 1) and axial (image 2) images from fetal MRI show an abnormal appearance of the kidneys (arrows) with multiple cortical cysts and massive enlargement of the ureters (arrowheads). On postnatal voiding cystourethrogram (image 3) bladder rupture is visible. Contrast fills the urinary bladder (arrowhead). There is leakage of contrast (arrow) from the right lateral aspect of the bladder and pooling (dashed arrow) within the right lower quadrant. Posterior urethral valves is the most common cause of fetal bladder outlet obstruction. Bladder rupture is an uncommon manifestation of this obstruction. High-grade vesicoureteral reflux is more common and leads to kidney damage.

A 68 year-old male presents with a recent history of hematuria and a bladder mass seen on cystoscopy. The patient undergoes a bladder washing which is submitted to the cytopathology laboratory; some representative fields are seen in the above figure. A concurrent tissue biopsy of the mass is taken, but the interpretation is limited due to extensive crush artifact in the specimen. What would be the most appropriate diagnosis (and any associated comments) for the bladder washing specimen based on the cytomorphological findings seen above?](https://app.figure1.com/case-detail/4c885d61-2c43-4785-ba84-9be307b6a7a1)
