Background: Mucosal melanoma is a rare form of melanoma presenting variably as sores or unexplained bleeding located mainly in the head and neck region, anorectal region or female genital tract. Mucosal melanoma is usually diagnosed at an advanced stage and is characterized by an aggressive behavior. Surgery represents the mainstay of treatment for early stage melanomas, but for advanced disease there have been until recently very limited treatment options.

Objectives: To compare the density of lymphatic vessels and VEGF-C and VEGF-D expression in Warthin's tumours (WTs) and oncocytic adenomas (OCAs).
Methods: Twenty three WTs and 13 OCAs of the parotid gland were analyzed. Lymphatic vessels were detected using the D2-40 antibody.
Aims: Some human neoplasms stimulate lymphangiogenesis through the over-production of vascular endothelial growth factors C/D (VEGF-C/D). Previously little attention has been paid to the mechanisms of lymphogenous spread of salivary adenoid cystic carcinoma (SACC). The current study investigates the presence of lymphatic network and the role of VEGF-C and VEGF-D in its formation.

The cornerstone is to distinguish transudative pleural effusion from exudative pleural effusion. In the case of the exudative pleural effusion the next step is detection of malignant etiology of pleural effusion.

Background: The differential diagnosis of the pathogenetic causes of hirsutism in combination with hypertension is a challenge for clinicians.
Methods And Results: This case report demonstrates a patient suffering from two hormonally active tumors - an adrenal adenoma with primary aldosteronism and a Leydig cell ovarian tumor with hyperandrogenism. The task of the authors was easier due to the perimenopausal age of the proband.
Purpose Of The Report: Cases of synchronous non-Hodgkin lymphoma (NHL) and second primary carcinoma in previously untreated immunocompetent patients are relatively rare. The aim of this part of our prospective study was to a revealed 2-F-18 fluoro-2-deoxy-D-glucose (F-18 FDG) positron emission tomography (PET)-positive lesion in an extranodal organ suggestive of second primary neoplasm in newly diagnosed NHL patients.
Materials And Methods: A total of 209 patients with NHL underwent initial staging F-18 FDG PET/computed tomography (CT).

Background: Peripheral T-cell lymphomas (PTCL) are infrequent subtypes of non-Hodgkin's lymphomas. The clinical course is aggressive and the median survival is about 2-3 years. An optimal first-line chemotherapy protocol has not been established and the role of high-dose therapy with autologous stem cell transplantation (ASCT) is still unclear.

The intensity of (18) F-FDG accumulation may be determined by calculating the so-called standardised uptake value (SUV). The study aimed at assessing the benefit of SUV(max) determination in staging (18) F-FDG PET/CT in untreated patients with NHL.

Aims And Methods: The goal was to investigate the effect of prior combined rituximab (R) and intensive chemotherapy on peripheral blood stem cell mobilization and their engraftment after stem cell transplantation (ASCT) in 69 patients with poor-risk, diffuse large B-cell lymphoma (DLBCL).
Results: A statistically comparable median number of CD34+ stem cells was collected in both groups (13.80x10(6)/ kg in the non-R group and 7.
Background: Acute promyelocytic leukemia (APL) is a relatively rare subtype of acute myeloid leukemia. It has become the best curable subtype of acute leukemias in adults due to the inclusion of all-trans-retinoic acid (ATRA) in the treatment. Despite the efficacy of ATRA, chemotherapy must be added in APL patients in order to maintain durable complete remission.

Background: Nodal peripheral T-cell lymphomas (PTCLs) are infrequent subtypes of non-Hodgkin's lymphomas. The WHO classification recognizes three subgroups of nodal PTCL: peripheral T-cell lymphoma not otherwise specified (PTCL, NOS), anaplastic large cell lymphoma (ALCL) and angioimmunoblastic lymphoma (AIL). The clinical course is aggressive and despite multiagent chemotherapy, the median survival is about 2 years.

Aims: To evaluate the role of dynamic contrast-enhanced magnetic resonance imaging (MRI) in the diagnosis of BI-RADS-5 type of microcalcifications of the breast, to compare the size of the microcalcification lesions using mammography (MG) and MRI, and to determine the value of MRI in surgery for microcalcifications. The study also determines the morphology of microcalcification lesions, assesses kinetic curves and compare MRI features of ductal carcinoma in situ (DCIS) for different histopathological grades.
Methods: Our group consisted of 32 patients with mammographically detected BI-RADS 5 microcalcifications.
Parathyroid cysts are uncommon lesions that do not have a specific sonographic appearance. We report a rare case of a functionally active cystic parathyroid adenoma as a cause of primary hyperparathyroidism and discuss the difficulties associated with the diagnosis. In this case, the association with a multinodular goiter made preoperative differentiation from thyroid cysts difficult.

Background: Monoclonal antibodies have dramatically changed the treatment possibilities for follicular lymphoma. (90)Y-ibritumomab tiuxetan (Zevalin) is the first radioimmunotherapy agent approved for the treatment of relapsed and resistant follicular lymphoma patients. Long-term benefit was observed especially for patients achieving CR after radioimmunotherapy.

T-cell gamma/delta hepatosplenic lymphoma is a primary extranodal lymphoma, distinct from other T/LGL lymphomas. The clinical course is aggressive, and despite use of the multiagent chemotherapy and young age of the patients, the median survival is less than 1 year. Curability of this disease is still uncertain.
