ABSTRACT
Cystadenoma of salivary glands is an uncommon benign neoplasm that presents intraluminal papillary projections. The authors describe one case of cystadenoma located in the buccal mucosa and highlight its histomorphological features and differential diagnosis.
O cistadenoma de glândula salivar é uma neoplasia benigna incomum, que exibe projeções papilíferas intraluminais. Os autores descrevem um caso de cistadenoma localizado na mucosa jugal, discutindo os aspectos histomorfológicos e o diagnóstico diferencial desse tumor.

Papillary solid and cystic neoplasm (PSCN) is a rare neoplasm of the pancreas with low-grade malignant potential and favorable prognosis. We report an 18-year-old girl with PSCN presenting with advanced disease. The tumor regressed with six cycles of gemcitabine and cisplantin-based neoadjuvant chemotherapy; spleen-preserving distal pancreatectomy was then done. She is disease-free at 13 months' follow-up.

Fine needle aspiration cytological features of solid-cystic tumor (SCT) of pancreas occurring adjacent to pancreas is reported for its rare occurrence. On cytology, diagnosis of paraganglioma was suggested. After histologic diagnosis of SCT, cytology was reviewed that showed typical features of SCT. On cytology, diagnostic problem in SCT occurring outside pancreas is illustrated.

Solid and papillary tumors of the pancreas are very rare malignancies, more commonly occurring in young women. They usually present as asymptomatic, large abdominal masses, and different from the most common neoplasm of the pancreas, which is the adenocarcinoma, these tumors have a high percentage of curability when treated by complete surgical resection. (6) For this reason, when the diagnosis of Frantz's tumor is made or strongly suspected, every attempt should be made for complete surgical excision since curability is high and radiotherapy and, or chemotherapy are of no use for its treatment

During a period of four years three cases of solid and cystic (papillary) tumour of the pancreas were encountered. The patients presented predominantly with chief complaints of lump abdomen associated with dull aching pain in right hypochondrium. Radiologically diagnosis was suspected in two cases. Excessive bleeding during surgery was observed in two cases. In two survivors no recurrence or distant metastasis was noted after surgical excision (follow up 6 months to 3.5 years), third patient died after eight hours of operation.

Paratesticular tumors are uncommon tumors, most being found incidentally at autopsy. The most common benign paratesticular tumor is the adenomatoid tumor. A somewhat less frequent benign paratesticular tumor, papillary cystadenoma, accounts for approximately 33 percent of all the primary epididymal tumors and is frequently seen in patients with Von Hippel-Lindau disease. Malignant tumors are rare. Of these, rhabdomyosarcoma is the most frequent. Seen almost exclusively in the pediatric population, paratesticular rhabdomyosarcomas account for 7 percent of childhood rhabdomyosarcomas. We describe two cases of paratesticular tumors in adults: a papillary cystadenoma of the epididymis in a 72-year old male, and an incidental rhabdomyosarcoma in a 49-year old male
