Perivascular epithelioid cell tumor (PEComa) is a very rare lesion and is described by the World Health Organization (WHO) as a mesenchymal tumor composed of histologically and immunohistochemically distinctive perivascular epithelioid cells. In this report we describe PEComa with perirenal manifestation, which is exceedingly rare and to our best knowledge up to now worldwide only three cases have been described. Despite the reports that most PEComas are benign, this tumor met criteria for malignancy and coexisted with mucinous gallbladder cancer and nonresectable pancreatic head tumor...

Mixed acinar-ductal carcinoma is rare among pancreatic cancers, as is duodenal involvement in follicular lymphoma (FL). Although usually a systemic disease, primary FL of the duodenum occurs, with superficial involvement of the intestinal wall and low risk of progression. We report on a unique case of mixed ductal-acinar carcinoma of the pancreatic head accompanied by low-grade duodenal FL and autoimmune pancreatitis-like changes in adjacent pancreatic parenchyma. To our knowledge this is the first report of concomitant pancreatic mixed acinar-ductal carcinoma and duodenal FL...

Tumor-to-tumor metastases are very rare events. We report a case of a 64-year-old man who presented with a tumor of the pancreas. The patient underwent partial pancreatectomy. Frozen section diagnosis of the tumor was an endocrine neoplasm. Paraffin block slide examination revealed a tumor consisting of two components: pancreatic endocrine neoplasm at the periphery of the tumor and the central part composed of clear cells with delicate vessels. The results of immunohistochemical stains revealed renal cell carcinoma surrounded by pancreatic endocrine neoplasm, therefore representing an unusual case of renal cell carcinoma metastasizing to a pancreatic endocrine neoplasm...

We present a case of a 52-year-old man with myasthenia gravis and a mediastinal tumor who was admitted to our hospital for surgical treatment. The pathologic examination of the resected tumor revealed a very rare case of a collision tumor: a B1B2 thymoma and a small lymphocytic lymphoma. Flow cytometry of the peripheral blood revealed the presence of a small number of leukemic cells. After postoperative irradiation of the mediastinum and chemotherapy a complete response in both diseases was achieved. The case confirms that a pathologist should always be aware that two different neoplasms can coexist in rare cases...

Renal cell carcinoma (RCC) with t(6;11)(p21;q12) has been incorporated into the recent WHO classification. We performed a clinicopathological study of 5 cases with such a tumor. The patients consisted of 4 males and 1 female. The age of patients ranged from 17 to 57 years with a mean age of 38.6 years. Tumor sizes ranged from 2.8 to 11 cm with a mean value of 6.5 cm. Despite immunotherapy and molecular-targeted therapy, one patient died of the disease 28 months after the surgery. Grossly, the cut surface of this tumor showed grayish white color in at least the focal area of all tumors...

The prognosis of oral tongue squamous cell carcinoma (OTSCC) is poor, and it would be beneficial to identify prognostic markers for optimization of treatment. Protein tyrosine kinase 7 (PTK7) is a receptor tyrosine kinase that is aberrantly expressed in human cancers. No exploration of the role of PTK7 in OTSCC has been reported. We detected expression of PTK7 protein in a set of tissue samples of OTSCC. The relationship between PTK7 expression and clinicopathologic parameters and overall survival of patients was analyzed...

Several lines of evidence indicate that immune cells in the tumor microenvironment play an important role in regulating tumor progression. An immunohistochemical method was used to examine the abundance of natural killer (NK) cells, mucosal dendritic cells (DCs), macrophages, mast cells, and microvessel density in 78 cases of oral squamous cell carcinoma (OSCC): with better prognosis - OSCCBP (n = 37), and with poorer prognosis - OSCCPP (n = 41), and 18 controls. The mean numbers of macrophages and microvessels were significantly higher in the OSCCPP group in comparison to both OSCCBP and control groups...

We aimed to evaluate whether obese women experience more advanced invasive breast carcinoma (IBC) with a higher number of involved lymph nodes, higher range of axillary lymph node ratio (LNR) and presence and size of extracapsular extension as it may have an impact on prognosis and management. 245 patients diagnosed with IBC were divided into normal weight (NW), overweight (OW) and obese (OB) groups. Patients were divided into high range of LNR (LNR over or equal to 0.2) and low LNR (LNR less than 0.2). The extracapsular extension dimensions were measured on the original slides of each case and grouped into ≤ 1 mm and > 1 mm...

Recent studies have confirmed the role of tumor-infiltrating lymphocytes (TILs) in carcinogenesis and cancer progression. The aim of this study was to evaluate the correlation between the level of tumor lymphocyte infiltration and well-known clinicopathological factors in breast cancer patients. We also evaluated the influence of TILs on overall survival. Paraffin sections were retrospectively evaluated in 76 cases in early stage breast cancer patients who underwent surgery followed by systemic treatment. Tumor-infiltrating lymphocytes were classified as absent (grade 0), mild (grade 1), moderate (grade 2), or severe (grade 3)...

According to the St. Gallen 2011 consensus, proper qualification of breast cancer patients for treatment requires taking into consideration the division into biological types of neoplasms. The goal of this work was to assess the prevalence of all biological types of breast cancer in the population of Kuyavian-Pomeranian province. We determined the influence of particular types of neoplasms on the degree of disease progression and the choice of therapeutic management. The study was conducted on a group of 2653 patients treated surgically due to malignant breast tumors in the Oncology Centre in Bydgoszcz...

X-linked agammaglobulinemia (XLA) diagnosed in the first year of life is an immunodeficiency with a life-long indication for substitution of immunoglobulins, due to lack of B lymphocytes in the periphery. The decrease of bacterial infection frequency and severity is an effect of immunoglobulin replacement. However, in the majority of patients bronchiectasis and chronic sinusitis with an overgrown mucous membrane develop despite regular substitution. Autoimmune diseases as co-existing diseases in XLA are noted in a few patients presenting symptoms associated with arthritis, scleroderma and myositis...

We report a case of IgA-dominant postinfectious glomerulonephritis in a 49-year-old man presenting with acute kidney injury, nephrotic range proteinuria and hematuria. He suffered from ischemic heart disease, cardiac insufficiency, mitral regurgitation, tricuspid insufficiency, septal aneurysm and hypertension. Renal biopsy revealed segmental and focal endocapillary and mesangial hypercellularity, and thickening of the glomerular capillary wall. Immunofluorescence showed co-dominant strong coarse granular immunostaining of IgA, IgG and C3 mainly along the glomerular capillary wall...
