Composite neuroendocrine and adenomatous carcinoma of the papilla of Vater.

Malignant tumors of papilla are usually adenocarcinomas. We present a 67-year-old female who became icteric as result of a malignant tumor infiltrating the papilla of Vater. Histopathological assessment of surgically excised tumor showed both neuroendocrine and adenocarcinomatous features.

Successful treatment of placental site trophoblastic tumor in twin pregnancy without hysterectomy.

To the best of the authors' knowledge, no case of placental site trophoblastic tumor (PSTT) pertinent to twin pregnancy has yet been published. There are only few case reports concerning patients with PSTT who were successfully treated by fertility-sparing methods. A 29-year-old nulliparous woman was admitted to hospital in the 36th week of a twin pregnancy due to symptoms of preterm labor.

[Malignant lymphoma or inflammation? Diagnostic and treatment difficulties--2 cases report].

Soft and hard tissue in the oral cavity can be the first coexisting place of systemic diseases manifestation. The aim of this study was to report the diagnostic and treatment difficulties in two patients with malignant lymphomas. The first case was a 66-year-old woman who had undergone surgery procedures connected with radiotherapy and chemotherapy because of malignant lymphoma in nasal cavity in 2001 year.

[Distant metastases to the parotid gland--review of the literature and report of own two cases].

Metastatic tumors to the parotid gland are very uncommon and it accounts for 8% of all cancers of parotid gland. The parotid gland and its lymph nodes are possible sites of metastases from head and neck cancers. However, metastasis from distant primary neoplasm below clavicle is possible, too.

[Carcinosarcoma of the pancreas--case report and literature review].

Forty seven year old man underwent laparotomy because of obstructive jaundice. As a cause of biliary tree obstruction a tumor of the head of the pancreas was diagnosed. Pancreatoduodenectomy was performed.

[Compatibility of the results of ultrasound-guided fine needle aspiration biopsy with the histological findings in assessment of focal breast lesions among woman attending the outpatient breast clinic].

Continuous increase of morbidity and mortality rate due to breast cancer has led to development of new diagnostic methods that are aimed at detecting neoplastic and preneoplastic lesions in their early, yet asymptomatic stages. Development of modern imaging techniques (ultrasonography, mammography, magnetic resonance) and invasive diagnostic procedures (fine needle aspiration biopsy, core needle biopsy, stereotactically guided biopsy) allows to detect lesions not exceeding 1 cm in diameter, and therefore may provide a complete cure. The aim of this study was to estimate diagnostic usefulness of ultrasound-guided fine needle aspiration biopsy in detecting benign breast dysplasia (with and without proliferation of ductal epithelial cells), benign neoplastic lesions and breast cancer, as well as to determine compatibility between US-guided FNAB results and subsequent histological findings.

[Diagnostic procedure in breast tumor--case report].

The paper presents the case of small impalpable breast tumors. Easy and successful diagnostic localization procedures with subsequent surgery were described.
