Tubulocystic carcinoma of kidney: A challenging diagnostic entity mimicking multicystic
kidney and presenting with bone metastasis.
, peritoneal mesothelioma: a report with electron microscopy of a case mimicking intra-abdominal cystic hygroma (lymphangioma) Cancer.
36) On gross pathology, TC-RCC appears as a well-circumscribed, encapsulated, multicystic
tumor with a characteristic "bubble wrap" or "sponge" appearance.
The ultrasound characterized a peripherally calcified, multicystic
, and septated lesion that was close to both the pancreatic tail and the upper pole of the left kidney.
Magnetic resonance imaging revealed a multicystic
mass with little perifocal edema (Figure 1).
The differential diagnosis of a cystic mass located between the kidney and the spine includes urinoma, lymphangioma, hemorrhagic neuroblastoma, mesenteric cyst, enteric duplication, multicystic
kidney disease, polycystic kidney disease and ureteric duplication.
Multiple mesothelial-lined cysts, also known as benign multicystic
mesothelioma, represent a rare but well-described entity that may enter the differential diagnosis of mesothelial neoplasia.
The most commonly diagnosed CAKUT include a multicystic
dysplastic kidney (MCDK), vesico-ureteric reflux (VUR) and obstructive uropathy due to posterior urethral valves (PUV) or pelvoureteric junction obstruction (PUJO).
A 8-year old boy was operated for multicystic
craniopharyngeo ma three years previously and after this operation he progressively lost vision and hearing ability and developed hydrocephalus (Figure 1).
Sectioning the orchidectomy specimen revealed a well circumscribed, predominantly multicystic
, mass measuring 17 mm in the tail of epididymis (Figure 1).
Multiple areas of necrosis may give leiomyosarcomas a cystic or multicystic
