BAT are multilocular
cells that have lipid droplets scattered throughout cytoplasm.
The lesion may be uni- or multilocular
and contain internal septations; the resultant "honeycomb" or 'bubbly" appearance is typical but not pathognomonic.
The differential diagnosis for TCC includes collecting duct carcinoma, multilocular
cystic renal cell carcinoma, cystic nephroma, and mixed epithelial and stromal tumors.
Imaging demonstrates massive, bilateral multilocular
radiolucent cystic areas within the gnathic bones (figure 2).
marginatus are as follows: body elongate oval, 8 antennal segments, 17 pairs of cerarii, oral-rim tubular ducts restricted to margin and sub-margin on dorsum, presence of translucent pores only on hind coxa, these unusually large and abundant, ventral oral-rim tubular ducts present on lateral areas of the thorax, ventral multilocular
pores absent from lateral areas of abdomen, anal bar present ventrally on each anal lobe, and dorsal setae generally equal to or shorter than conical cerarian setae (Fig.
The lesion comprised a circumscribed, fibrous-encapsulated multilocular
cyst, lined by plump, goblet-type, cuboidal epithelial cells lying in abundant mucinous matrix.
Worse, it can cause alveolar hydatid disease or multilocular
hydatidosis, a truly scary disease, which results in hundreds of tumor-like cysts in the lungs.
Depending on the stage of disease, the cyst can range from simple to a multilocular
complex cystic lesion.
Cases within the "other" subgroup included: acquired cystic disease-renal cell carcinoma (ACD-RCC; n = 4); translocation-associated RCC (TA-RCC; n =4); multilocular
cystic RCC (n = 5); squamous cell carcinoma (n = 2); and 1 case of renal medullary carcinoma.
The fossil fruit Duabangocarpon deccanii Kadoo and Kolhe (2002) is a multilocular
capsular fruit from the Maastrichtian-Danian Deecan Intertrappean Beds at Mohgaon Kalan.
cysts, as in our case are very rare accounting for only 4% of the cases (8).
The differential diagnosis of cystic angiomyolipomas involves distinguishing between mixed epithelial and stromal tumors (previously classified as cystic hamartomas of the renal pelvis, adult mesoblastic nephroma, or renal pelvic or cortical hamartomas), cystic nephroma, multilocular
cystic renal cell carcinoma, liposarcoma and vascular malformations.
