ABSTRACT
Papillary adenoma (PA) of kidney is defined as a lesion measuring less than 15 mm and featuring papillary or tubular architecture along with nuclei of low grade.Clear cell renal cell carcinoma (CCRCC) is the most common seen group of malignant neoplasms consists of cells with clear or eosinophilic cytoplasm.The coexistence of these two kinds of tumor is rare and was only reported in one piece of literature to date.We report a thought-provoking case in which CCRCC is coexisting with multiple PAs.The CCRCC shows no difference with other common cases while the PAs share the same clinical and pathological features with other ones and demonstrates no amplifying of 3,7 or 17 chromosome.However,the multiple PAs were neglected by imaging doctors and surgeons,and some tiny lesions were not found until the observation under microscope.This case reminds that patients accepting partial nephrectomy for CCRCC may have PAs,so attention should be paid to the image studies along with routine pathological examination of kidney for that there may exists two or more kinds of lesions.

We report herein an uncommon tumor of the nipple. A 26 year-old woman visited our outpatient department of plastic surgery for skin lesion and discharge from the right nipple. Biopsy was performed on the lesion, and diagnosed as papillary adenoma. The nipple was resected and reconstructed including adjacent subareolar tissue. Thus, full thickness skin was harvested from labium minor and grafted on the reconstructed nipple. Donor site was primarily closed. On the histologic study, the lesion was compatible with florid papillomatosis of the nipple(adenoma of the nipple). In 2 months follow-up period, we could not find any complications such as skin necrosis, infection, wound dehiscence, or tumor recurrence. This is a case of papillary adenoma of the nipple which was excised and successfully reconstructed with local flap.

Aggressive digital papillary adenoma is a rare neoplasm of eccrine sweat gland origin. We report a case of aggressive digital papillary adenoma with literature reviews. Pathogenesis of this tumor is unclear but, according to his past history, possible induction by defoliants could not be ruled out. Several immunohistochemical studies were done to confirm tumoral origin and to evaluate histological potential of malignancy.

Biliary papilloma usually consists of single or multiple papillary adenomas in the biliary tract and has a potential for recurrence and malignant transformation. We described herein a case of papillary adenoma of intrahepatic duct that transformed into papillary adenocarcinoma. A 49-year-old male patient was admitted to our hospital because of right upper quadrant pain. A CT scan revealed marked dilatation of S7 segmental duct and cholangioscopy and biopsy revealed mucin-secreting papillary adenoma in the right intrahepatic duct. Three years later, a follow up of CT scan showed aggravated S7 ductal dilatation and inner ill-defined mass. Cholangioscopy revealed multiple papillary mucosal projections with large amount of mucin in the right intrahepatic duct and biopsy revealed well differentiated papillary adenocarcinoma. The patient underwent right lobectomy, the papillary adenocarcinoma was extended in the dilated right intrahepatic duct and also showed hepatic parenchymal invasion.

A 24-year-old woman was seen for evaluation of an skin lesion on thiright nipple. Examination revealed a solitary 1.5 x 1cm-sized, erythematous, oozing, eroded andruted, verrucous nodule on the right nipple. A small amount of serous discharge was found but there was no pain or tenderness. Histopathologic findings showed cystic invaginations extending down vard from the epidermis and papillary projections extending into the lumina of the invagination. Pupiae were lined by two rows of cells. In stroma, there were marked inflammatory infiltrates containing any plasma cells. The overlying dermis showed an adenomatous growth pattern with a prolifertion of round, oval or irregular shaped ducts and fibrotic stroma.

Prostate papillary adenoma is very rare benign disease in posterior urethra and until recently, it was called under the various different names. There is no case which was reported in this country until now. We experienced two cases of prostate papillary adenoma in patients over 55 years old who had combined with lower urinary tract obstructive symptoms and we report these cases with the review of literatures.
