Renal medullary carcinoma, also referred to as the seventh sickle cell nephropathy, is an extremely rare malignant neoplasm occurring almost exclusively in patients with sickle cell trait ( ATT: board question !!!). Rrenal medullary carcinomas show sheets of poorly differentiated, mucin-producing eosinophilic cells associated with inflammatory, fibrous, or edematous stroma. Characteristic sickled erythrocytes are found in most tumors

The lesion consists of multiple locules, variable in size, each lined by epithelium, and the entire mass circumscribed by a thick capsule. The stroma is quite cellular in some areas and, unlike dysgenesis, contains no glomeruli.

The typical Wilms' tumor consists of three elements, all seen on this slide: epithelial, stromal and undifferentiated. The darkly staining, intensely cellular areas are the undifferentiated nephrogenic component. In places, these appear to differentiate into tubules, occasionally glomeruloid structures all lined by neoplastic cells. The above structures are contained in a spindle cell stroma.

The lesion is very pleomorphic with numerous mitotic figures. Three distinct cell types may be identified: very small ones with round, pyknotic nuclei and pink cytoplasm, very large, sometimes bizarre, cells with either dark or vacuolated nuclei and a third predominant type, comparable in size to the cells of typical seminoma. The latter two-cell types often display a rather distinctive chromatin pattern which is filamentous spireme-like, rather than punctate, as in other seminomas.

Note the marked anaplasia of the cells, mitotic activity, hemorrhage and tumor necrosis.

There is a testis with seminiferous tubules lined mostly by Sertoli cells, and some of the lumina are calcified. A tumor is present in the tubules and consists of two elements: seminoma-like germ cells and Sertoli-granulosa cells arranged around pink, round masses resembling Call-Exner bodies. This combination of stromal and germ cell tumor constitutes gonadoblastoma. There is also marked Leydig cell proliferation.

Urothelial mucosa with moderate to marked anaplasia, failure of maturation from the base to the surface, condensation of nuclei and many mitotic figures in various levels of the epithelial layer.

The glands are approximately the size of other hyperplastic glands, the secretory cells have a normal appearance except that they are markedly increased in number and show cribriform bridging across the lumen or largely fill the lumen. This has been reported as "clear cell cribriform hyperplasia" although the cells are not water clear. This is distinguished from PIN by the absence of any nuclear atypia and from cribriform carcinoma by the presence of basal cells.

Grossly, adrenocortical carcinomas are often large, with a tan-yellow cut surface, and areas of hemorrhage and necrosis. On microscopic examination, the tumor usually displays sheets of atypical cells with some resemblance to the cells of the normal adrenal cortex. The presence of invasion and mitotic activity help differentiate small cancers from adrenocortical adenomas. There are several relatively rare variants of adrenal cortical carcinoma: Oncocytic adrenal cortical carcinoma, Myxoid adrenal cortical carcinoma, Carcinosarcoma, Adenosquamous adrenocortical carcinoma, Clear cell adrenal cortical carcinoma. Differential diagnosis includes: Adrenocortical adenoma, Renal cell carcinoma, Adrenal medullary tumors, Hepatocellular carcinoma.

Multilocular cystic renal tumor is characterized as a solitary, well-circumscribed, multiseptated mass of noncommunicating fluid-filled loculi that is surrounded by a thick fibrous capsule and compressed renal parenchyma. The mass is typically large. I
