Locally Advanced Adenoid Cystic Carcinoma of the Breast-A Case Report with a Review of the Literature.

Breast cancer (BC) is a heterogeneous disease distinguished by four main subtypes based on the expression of estrogen, progesterone receptors, and human epidermal growth factor-2 on the cancer cells. Triple-negative breast cancer (TNBC) consists of approximately 10-20% of all BCs and is characterized by a poor prognosis. Adenoid cystic carcinoma (ACC) of the breast is a rare, special type of TNBC with low metastatic potential and usually favorable prognosis.

Limitations of Systemic Oncological Therapy in Breast Cancer Patients with Chronic Kidney Disease.

Breast cancer is the most common malignancy, affecting middle-age and older women frequently suffering from other chronic diseases, including chronic kidney disease. The risk of breast cancer development in women on renal replacement therapy (peritoneal dialysis and haemodialysis) is higher than in the general population. Chronic kidney disease does not limit surgical treatment or radiotherapy; however, it affects the pharmacokinetics of drugs used in the systematic treatment to a different extent, increasing their toxicity and the risk of adverse drug reactions.

Acanthosis nigricans as a paraneoplastic syndrome. Case reports and review of literature.

Acanthosis nigricans (AN) is a skin disorder characterized by focal or diffuse hyperkeratosis symmetric hyperpigmentation of the skin and oral cavity mucosa. Various neoplasms, especially gastrointestinal adenocarcinomas are associated with acanthosis nigricans (AN malignant). Chemotherapy may cause regression of skin lesions.

[CD20 antigen of Hodgkin and Reed-Sternberg cells as possible prognostic factor in patients with Hodgkin's lymphoma--preliminary reports].

Unlabelled: THE AIM of the study was to asses the validity of CD20 expression on H-RS cells as independent prognostic factor in patients with Hodgkin's lymphoma.

Methods: 72 patients (44 men and 28 women) between 15 and 73 y.o.

[Diagnostic difficulties in diagnosis of splenic abscesses].

We report an 18-year old patient with hypochromic anaemia and subfebriles states and long-persisting despite symptomatic treatment. On admission he presented body proportions similar to Marfan syndrome. Hypochromic anaemia and positive inflammatory markers were present along with negative results of serologic and microbiological assays.

Focal lesions in the ultrasonographic examination of the spleen as a symptom of various disease statuses: literature survey and case descriptions.

Background: Ultrasonography (US) is an easy and non-invasive technique of visualizing spleen. Thanks to its repeatability, it plays an important role in the diagnostics of, among others, developmental anomalies, such as supernumerary or lobated spleens, as well as focal lesions. It is also used in monitoring the size of the spleen and it considerably facilitates diagnosis after certain injuries.

[Primary lymphoma of the thyroid--diagnostic and treatment problems. The case report].

The authors present the case of primary malignant thyroid lymphoma and problems with distinguishing between Hashimoto's thyroiditis and primary thyroid lymphoma. Primary malignant thyroid lymphoma (PMTL) is a rare disease and difficult to diagnose. The appearance of PMTL may be preceded by Hashimoto's thyroiditis.

[Malignant neoplasms of the small intestines].

The paper contains a retrospective study of 12 cases of malignant small bowel tumors observed and treated in the Department of Oncological Chemotherapy of Medical University of Silesia. The authors presented the most common symptoms, typical diagnostic procedures and the difficulties in the diagnostics of small bowel neoplasms.

Expression of TGF beta1 genes and their receptor types I, II, and III in low- and high-grade malignancy non-Hodgkin's lymphomas.

Background: Transforming growth factor beta (TGF ) is involved in a variety of important cellular functions. The lack of TGF -dependent cell-growth control might be related to oncogenesis, as it has been shown in lung, breast, and colon carcinomas. Current observations have revealed that TGF is rather an inhibiting, not a stimulating, factor as far as malignant tumor development is concerned.

[Current principles of Wilson's disease--diagnosis and treatment].

Wilson's disease defined also as hepatolenticular degeneration is an important clinical problem of young adults still causing diagnostic difficulties. In the course of the last decade, genetic background of the disease has been definitely established and elucidated, confirming the variety of genetic mutations, responsible for its origin. The current scheme of the disease treatment has been elaborated and established.

[Ormond's fibrosis, bone osteolysis and stomach intramural metastases in the course f low-differentiated prostatic cancer].

Retroperitoneal fibrosis (Ormond's disease) is rare chronic inflammatory process, that can occur at any age. It is characterised by development of periaortic fibrous mass leading to progressive obstruction of vessels around the abdominal aorta and ureters. In the one third of cases we can find the causes of disease.

Elastin metabolism parameters in sera of patients with lung cancer.

Elastin metabolism parameters (elastin-derived peptides and elastase-like activity) were determined in sera of patients with lung cancer and in healthy controls. The concentration of elastin-derived peptides was statistically significantly elevated in the lung cancer group. There was no statistically significant difference in the serum elastase-like activity between the groups studied.

Anti-elastin antibodies in patients with lung cancer.

The aim of this study was to investigate anti-elastin antibodies of the IgG and IgM types in sera of patients suffering from lung cancer, using the DOT immunobinding assay. We studied 96 pathological and 40 control sera. Anti-elastin antibodies were found to be present in 45% of patients with small cell lung cancer, 19% of subjects with adenocarcinoma and not-identified lung tumor and 15% of patients with squamous cell lung cancer.

Immunoglobulins and complement components levels in patients with lung cancer.

Sera from 96 patients with lung cancer were assayed in order to evaluate the concentrations of IgG, IgA, IgM, C3c and C4. Histologically, 49 of the patients had squamous cell carcinoma, 11--adenocarcinoma, 20--small cell carcinoma and 16--not identified lung cancer. No statistically significant differences were found between the concentrations of IgG and IgM in patients with carcinoma of the lung versus subjects in the control group.

[Leiomyosarcoma of the stomach and small intestine].

Three cases of leiomyosarcoma are presented. The primary lesion to the stomach was seen in 2 patients while the small intestine in the remaining patient. Two patients underwent radical surgery.
