A 48-year-old Chinese woman presenting with continuing dull pain in the right lower back and abdomen was found to have a tumor with extensive osseous metaplasia in the upper-middle pole of the right kidney. The excised neoplasm specimen revealed a 29 × 26 mm hard tumor with dense ossification. Histopathological examination of the tumor showed that it contained lamellar bone forming trabeculae intermingled and spherical or polygonal epithelial cells that contained slightly irregular nuclei with small nucleoli and abundant pink to clear cytoplasm...

We report 13 cases of unique polypoid urothelial tumors with inverted growth pattern (PUTIPs) occurring in the proximal ureter and renal pelvis. We describe their morphologic features and further characterize them in regard to TERT promoter mutation status and microsatellite instability. Thirteen cases were identified in our consult archives from 1994 to present. Patients ranged in age from 52 to 83 years at the time of diagnosis (mean, 68.4 years). Grossly, lesions were described variously as pink-tan to white exophytic and friable lesions that were polypoid or pedunculated, located in the renal pelvis or proximal ureter...

Rare, sporadic uterine leiomyomas arise in the setting of severe metabolic aberration due to a somatic fumarate hydratase mutation. Germline mutations account for the hereditary leiomyomatosis and renal cell carcinoma syndrome, which predisposes for cutaneous and uterine leiomyomas and aggressive renal cell carcinomas. Altered fumarate hydratase leads to fumarate accumulation in affected cells with formation of S-(2-succino)-cysteine, which can be detected with the polyclonal antibody. High levels of these modified cysteine residues are found characteristically in fumarate hydratase-deficient cells but not in normal tissues or tumors unassociated with hereditary leiomyomatosis and renal cell carcinoma syndrome...

Adult onset Still's disease (AOSD) is a systemic inflammatory disease with unknown etiology and characterized by evanescent salmon pink rash, sore throat, liver dysfunction, lymphadenopathy, hepatosplenomegaly, arthritis, and leukocytosis. It is a diagnosis of exclusion; however, there are case reports in the literature about patients with malignancies and AOSD-like signs and symptoms. Here we report a patient with AOSD seems to be associated with sarcomatoid renal cell carcinoma. This phenomenon is not distinguishable from primary AOSD either in presentation or in treatment; except for the main purpose of the management should be targeted to the underlying malignancy...

Keratoacanthoma is a well-known, fast-growing, benign squamous epithelial neoplasm that usually presents as a solitary, dome-shaped, pink or flesh-colored nodule developing a central keratin-filled crater. Few authors consider it to be a benign cutaneous tumor whereas others suggest that it should be regarded as a low-grade variant of cutaneous squamous cell carcinoma (SCC). A 21-year-old female presented with a firm, nontender, well-defined plaque with irregular margins measuring about 8 × 4 cm over the dorsal aspect of the right foot along with an exuberant growth from the plaque measuring 4 × 5cm...

A 20-year-old African American male presented with a history of left flank pain and passing of light pink urine. Medical history included sickle cell trait. Urine analysis was positive for protein and blood. Metabolic profile, autoantibody screen, and complement levels were normal. Hemoglobin electrophoresis revealed an 41.8% HbS diagnostic of sickle cell trait. Creatinine clearance was normal and proteinuria was nonnephrotic. A noncontrast computed tomography (CT) scan showed left proximal hydronephrosis. Urology follow-up was arranged and the differential included renal papillary necrosis, or renal cyst rupture...

A 53-year-old Chinese man presented with a history of painful lesions on the chest of 20 years' duration. He experienced sharp pain especially on touching and after spicy food. The lesions were stable with no increase in size or number. He was otherwise well. There was no significant family history. Physical examination revealed multiple, grouped, pink papules on the left chest, extending to the right back in a segmental distribution, each measuring 2-5 mm (Figs 1 and 2). They appeared pearly and keloid-like, and had a firm consistency...

We report the rare but serious association between sebaceous carcinoma of eyelid and Muir-Torre syndrome in two cases, a 79-year-old woman and 54-year-old man. The presenting sign was a yellow-pink nodule with telangiectatic vessels on the left lower eyelid in one patient and a yellowish-red, pedunculated lesion with intrinsic vascularization on the right superior tarsal conjunctiva in the other. A history of multiple primary colon cancers was present in both patients, associated transitional cell carcinoma of bladder and renal cancer in one patient and prostate cancer in the other...

Renal oncocytomas are rare renal parenchymal neoplasms which have a good prognosis. An accurate pre-operative diagnosis by guided fine needle aspiration cytology helps to plan a more conservative surgery. Cytologic findings in a case of renal oncocytoma are presented. Smears showed polygonal or rounded cells in groups and acinar pattern having a well-defined, granular, eosinophilic cytoplasm, and round regular nuclei displaying very little pleomorphism. Intra and extracellular hyaline material staining pink with May Grunwald Giemsa stain were seen...

1-Amino-2,4-dibromoanthraquinone is an anthraquinone-derived vat dye, a member of a class of insoluble dyes that are impregnated into textile fibers. Five anthraquinone-derived dyes with representative and diverse structures, as well as the parent chemical, anthraquinone, were selected for NTP Toxicology and Carcinogenesis evaluation. Similar to the benzidine dye initiative, the rationale for selecting these vat dyes was to generate sufficient toxicologic data to permit more reliable predictions of carcinogenicity to be made on other chemicals in this class, thereby eliminating or reducing the need to study every anthraquinone dye...

A case of adult mesoblastic nephroma (MN) was erroneously interpreted as a benign mesenchymal tumor on fine-needle aspiration (FNA) cytology. MN is a rare tumor in infants and is extremely uncommon in adults. A 50-yr-old female presented with a renal lump with the clinicoradiological possibility of renal-cell carcinoma. Giemsa-stained smears were highly cellular and showed cohesive interlacing fragments of spindle cells embedded in abundant pink fibrillary stromal matrix. Epithelial component was seen in the form of tubules...

PURPOSE: Small renal tumors are frequently detected during the screening of patients with a hereditary type of renal cancer. The development of nonsurgical treatment modalities would greatly improve quality of life in these patients. We present our experience with radio frequency interstitial tissue ablation, a heating device approved by the Food and Drug Administration for treating soft tissue tumors. MATERIALS AND METHODS: Patients underwent radio frequency interstitial tissue ablation of small renal tumors just before surgical excision...

A 59-year old woman was diagnosed with a tumour in her right kidney. A nephrectomy was performed, and a 45 mm diameter tan-pink coloured tumour was found. Microscopy revealed small, dark cells in organized arrays of small round acini and tubules with glomeruloid infoldings. A diagnosis of metanephric adenoma was made. The tumour cells proved diploid on flow cytometry and immunohistochemical staining was positive for CAM 5.2 and AE-3. FISH analysis of three chromosomes did not reveal any abnormal karyotype. It is important to differentiate metanephric adenoma from renal cell carcinoma and adult Wilm's tumour, since it has a benign course...
