Primary intra-renal teratoma associated with renal dysplasia: an unusual entity.

Primary intrarenal teratomas are uncommon, and their association with renal dysplasia is rarer. We report a case of primary renal teratoma in a 1-year-old child who had undergone a retroperitoneoscopic nephrectomy. Pathologic examination showed evidence for a primary mature teratoma with renal dysplasia.

Serous microcystic adenoma (glycogen rich cystadenoma) of the pancreas.

Serous microcystic adenoma (SMCA) is a rare pancreatic tumor with a striking predilection for elderly females and a rather unique morphology. Classically, the tumor is riddled with innumerable small cysts around a stellate scar. The quintessential histological features are closely placed small cysts lined by glycogen rich cuboidal epithelium.
