ABSTRACT

During infancy, skin inflammation is usually treated in basic pediatric care. In this study, we present a case of an 8-month-old girl with a 2-month history of an inflammation of the thigh treated locally by ointments and oral antibiotics in basic and dermatological care. The patient had a history of fever, sweating, and failure to thrive. The lactate dehydrogenase was elevated up to 869 U/L with low C-reactive protein (1.04 mg/L). Magnetic resonance imaging of the thigh reassured the diagnosis of local inflammation. Intravenous antibiotic caused mild local improvement, but the episodes of high fever sustained. The patient was transferred to our pediatric surgery department for treatment and surgical biopsy of the lesion. Histopathological examination confirmed a subcutaneous panniculitis-like T-cell lymphoma, which is a rare cytotoxic T-cell lymphoma representing less than 1% of non-Hodgkin lymphomas, uncommon in children. The patient was introduced to a chemotherapy protocol EURO-LB 2002 with good response. In a skin lesion that is associated with systemic symptoms and responding untypically to antibiotic treatment malignancy should be considered and biopsy not be postponed.

ABSTRACT

The aim of this study was to assess the: 1) clinicopathologic features of papillary early gastric cancer (PEGC) (13 cases) compared to tubular early gastric cancer (TEGC) (41 cases); 2) efficiency of endoscopic submucosal dissection (ESD) in treatment of PEGC. From January 2007 to February 2016, a total of 54 consecutive patients with early gastric cancer (EGC) underwent ESD at the Department of Gastroenterology of the Pomeranian Medical University in Poland. The histologic type of carcinoma was assessed according to the WHO histological classification of GC. The extension of GC into the submucosa was measured using the Aperio Scan Scope image analysis system tools. PEGCs were diagnosed in 24.1% of the cases of EGC. PEGCs were significantly more elevated in macroscopic examination and better demarcated tumors than TEGC. There were no significant differences between gender, tumor location, ulceration, tumor size, depth of invasion (T), presence of intestinal metaplasia and lymphocytic infiltrate. Curative resection was achieved in 87.1% of patients with EGCs treated with ESD. The lower rate of curative resection (R0) observed in PEGC (76.9%) vs TEGC (90.2%) was not statistically significant. Further studies will be necessary to confirm the clinical and morphological presentation of PEGCs.

ABSTRACT

The correlation of thymidylate synthase (TS) expression in gastric cancers with tumor histology and prognostic or predictive information remains unclear. Most studies have involved Asian populations, with few conducted in European cohorts. Moreover, all published studies analyze TS expression using semi-quantitative methods. This retrospective study evaluated the association of TS expression in tumor cells with gastric carcinoma histological type, with selected clinicopathological parameters, and with the prognosis of patients who underwent surgical treatment. TS expression was detected using immunochemistry and objectively assessed by computerized image analysis of tumor cells in 100 gastric cancers. We found that high TS expression was significantly more common in intestinal than in diffuse type of gastric cancer according to Lauren classification (P=0.0003); in type I carcinomas compared to type IV according to Goseki classification (P=0.002); and in gastric cancers in men than women (P=0.04). Low TS expression was found more often in carcinomas in the middle and lower third of the stomach than in cancers in the upper third of the stomach (P=0.009 and P=0.001, respectively). In the subgroup of 25 patients without lymph node metastases (stage I+II), high TS expression was associated with better DFS (83% for high TS expression versus 38,5% for low TS expression, P=0.03). The results (1) indicate significant correlation between the Lauren and Goseki histopathological classifications of gastric cancer and TS expression in tumor cells, (2) suggest that high TS expression may be a positive prognostic marker with regard to DFS in patients with gastric cancer without involvement of regional lymph nodes who underwent radical surgical treatment and were not treated with preoperative chemotherapy. Prognostic results need confirmation in larger cohorts.

ABSTRACT

OBJECTIVE: Early gastric cancer (EGC) is defined as cancer invasion confined to the mucosa or submucosa, irrespective of lymph node metastasis. Recently endoscopic submucosal dissection (ESD) has been widely accepted for the treatment for dysplasia and EGC without lymph node metastases. While the method has been advanced in Far East countries, ESD is still being developed in Europe and has not gained enough popularity although it has been recommended as the treatment of choice for superficial gastric neoplastic lesions by European Society of Gastrointestinal Endoscopy (ESGE) in 2015. METHODS: The aim of the study was to perform a retrospective analysis of clinical and histomorphologic features of 58 cases of EGCs removed by ESD in a university hospital in Western Pomerania in Poland and to evaluate factors related to the efficiency of ESD resection. RESULTS: With univariate analysis, indications for ESD with the highest R0 rate were found in EGCs limited to mucosa (T1a, small mucosal, M), without muscularis mucosa invasion, localised in the middle/lower part of stomach and intestinal type in histological examination. The R0 complete resection rate was significantly (p < 0.0001) lower for T1b than that for T1a tumours (21.4% vs. 100%). Tumours with submucosal involvement were associated with lower efficiency of ESD procedure. CONCLUSIONS: Our data showed that in EGCs with favourable histomorphologic characteristics, ESD seemed to be a totally efficient and safe method of treatment in a European small-volume centre. R0 resection rate reached 81.1% of cases and median time of the ESD procedure was 61.5 min.

ABSTRACT

BACKGROUND Mutations in DNA of mismatch repair (MMR) genes result in failure to repair errors that occur during DNA replication in microsatellites, resulting in accumulation of frameshift mutations in these genes and leading to DNA mismatch replication errors and microsatellite instability. Gastric cancers (GCs) with high MSI (MSI-H) are a well-defined subset of carcinomas showing distinctive clinicopathological features. In this study we investigated the rate of MSI and the correlation between MSI status and clinicopathological features of GC. MATERIAL AND METHODS The study included 107 patients with GCs: 61 with advanced gastric cancers (AGC) and 46 with early gastric cancer (EGC). MSI deficiency in GCs was assessed by the immunohistochemical analysis of expression of MMR proteins - MLH1, MSH2, MSH6, and PMS2 - using formalin-fixed and paraffin-embedded tissue. RESULTS A total of 6 (5.6%) MSI-H were observed. The loss of MMR proteins expression was associated with the intestinal type of GC in Lauren classification, and tubular and papillary architecture in WHO classification. There was no statistically significant association between negative MMR expression and other selected clinical parameters: age, sex, tumor location, depth of invasion (EGC and AGC), lymph nodes status, presence of the ulceration, and lymphocytic infiltrate. CONCLUSIONS In the present era of personalized medicine, the histological type of GC and MMR proteins status in cancer cells are very important for the proper surveillance of patients with familial GC and sporadic GCs, as well as for selecting the proper follow-up and treatment. Larger collaborative studies are needed to verify the features of MSI-H GCs in Poland.

ABSTRACT

INTRODUCTION: Gastric cancer (GC) belongs to a group of cancers linked to BRCA2 gene mutations and observed in patients with a family history of breast and ovarian cancers. A common variant allele (C5972T) observed in the BRCA2 gene in the Polish population is associated with an increased risk of breast cancer. OBJECTIVES: The objective of the study was to assess a relationship between the BRCA2 C5972T variant and GC. PATIENTS AND METHODS: A total of 380 patients with GC (234 men and 146 women; mean age, 59.0 ±12.8 years) and 380 sex- and age-matched healthy individuals (234 men and 146 women; mean age, 59.0 ±12.9 years) were included in this retrospective study. Polymerase chain reaction-restriction fragments length polymorphism (PCR-RFLP) was used to detect the BRCA2 C5972T variant. We compared the frequency of BRCA2 allele carriers among patients and controls. We also compared selected clinical and pathological features between allele carriers and noncarriers among patients with GC. RESULTS: The BRCA2 C5972T variant was observed in 28 patients with GC (7.4%) and in 18 controls (4.7%) (P = 0.17). The odds ratio [OR] for GC in allele carriers was 1.59 (95% confidence interval [CI], 0.87-2.94). A comparison of selected clinical and pathological features between carriers and noncarriers did not show any significant differences. The analysis of a family history showed a trend for an increased risk of breast or ovarian cancer in the families of patients with GC carrying the C5972T allele (OR, 2.51; 95% CI, 0.80-7.88, P = 0.11). CONCLUSIONS: Our study showed that the C5972T allele is a low-penetrant variant of the BRCA2 gene, which tended to increase the risk of GC. Further research is needed to fully elucidate the role of BRCA2 polymorphisms in GC.

ABSTRACT

AIM: To determine the prevalence and characteristics of additional primary malignancies in gastric cancer (GC) patients. METHODS: GC patients (862 total; 570 men, 292 women; mean age 59.8 ± 12.8 years) diagnosed at the Department of Gastroenterology at Pomeranian Medical University over a period of 23 years were included in this retrospective analysis of a prospectively maintained database. Mean follow-up time was 31.3 ± 38.6 mo (range 1-241 mo). The following clinicopathological features of patients with synchronous tumors were compared to those with metachronous tumors: age, sex, symptom duration, family history of cancer, tumor site, stage (early vs advanced), histology, and blood group. GC patients with and without a second tumor were compared in terms of the same clinicopathological features. RESULTS: Of 862 GC patients, 58 (6.7%) developed a total of 62 multiple primary tumors, of which 39 (63%) were metachronous and 23 (37%) synchronous. Four (6.9%) of the 58 multiple GC patients developed two or more neoplasms. The predominant tumor type of the secondary neoplasms was colorectal (n = 17), followed by lung (n = 9), breast (n = 8), and prostate (n = 7). Age was the only clinicopathological feature that differed between GC patients with synchronous vs metachronous malignancies; GC patients with synchronous neoplasms were older than those with metachronous neoplasms (68.0 ± 10.3 years vs 59.9 ± 11.1 years, respectively, P = 0.008). Comparisons between patients with and without a second primary cancer revealed that the only statistically significant differences were in age and blood group. The mean age of the patients with multiple GC was higher than that of those without a second primary tumor (63.4 ± 11.4 years vs 59.5 ± 13.0 years, respectively, P = 0.026). GC patients with a second primary tumor were more commonly blood group O than those without (56.2% vs 31.6%, respectively, P = 0.002). CONCLUSION: GC patients may develop other primary cancers; appropriate preoperative and postoperative diagnostic modalities are thus required, particularly if patients are older and blood group O.

ABSTRACT

Thyroid metastases account for approximately 1.4-3% of all malignancies of the thyroid gland. Thyroid metastases are most common in: clarocellular carcinoma of the kidney, lung cancer, breast cancer, malignant melanoma and cancers of gastrointestinal tract. A rare situation is when thyroid metastasis is diagnosed before detecting primary malignant focus and when it is the first manifestation of underlying disease. We present a case of 64-year-old male with thyroid metastasis being the first manifestation of lung adenocarcinoma.The authors emphasize that patients with the history of malignancy should undergo an ultrasound examination of the thyroid gland in order to exclude a focal lesion, and if such lesion is detected, fine-needle aspiration biopsy is recommended. The authors also point out that establishing final diagnosis of thyroid metastasis of cancer in other organs is only possible on the basis of postoperative histopathology and immunohistochemistry.

ABSTRACT

The article presents a case of 57-year-old woman with the infiltration of rare small lymphocytic B cell lymphoma in the thyroid gland. Initially, the patient was followed-up due to chronic lymphocytic B-cell leukemia diagnosed on the basis of histopathological examination of cervical lymph node. Eight months later, general symptoms occurred along with lymphocytosis and exacerbation of lesions in lymph nodes, and therefore, chemotherapy was started according to COP regimen. After four chemotherapy cycles, further progression of the disease was observed during chemotherapy. Computed tomography (CT) performed at that time showed generalized lymphadenopathy and the presence of an irregular area in left thyroid lobe. On palpation, the thyroid was asymmetrical, with enlarged left lobe and palpable lymph node packages on the left side of the neck. The levels of thyroid hormones and anti-thyroid antibodies were normal. Ultrasound examination of the thyroid gland showed non-homogeneous hypoechogenic structure of the left lobe and complete focal remodeling. Cytological examination of left-lobe lesion obtained during fine needle aspiration biopsy showed multiple small lymphoid cells, suggestive of small lymphocytic lymphoma. To confirm this diagnosis, flow cytometry of the biopsy material sampled from the left lobe was performed showing B cellimmunophenotype: CD19+/CD20+/CD22 dim/FMC-7, CD23+/CD5+, sCD79b-+, CD38-, CD10-, kappa and lambda-/weak reaction. The results of flow cytometry of the thyroid bioptate and blood were nearly identical, confirming leukemic nature of the infiltration in left thyroid lobe. Cytogenetic findings included the presence of 17p deletion (TP53 gene). The patient received immunochemotherapy with alemtuzumab. The progression of the disease occurred in the sixth week of therapy. The treatment was discontinued after 8 weeks due to worsening of patient's general status. The patient died 15 months after the diagnosis.

ABSTRACT

The number of nephrons is a multifactorial trait controlled by the interaction of environmental factors and genetic variants that influence the extent of branching nephrogenesis during foetal life. A correlation between renal mass and nephron number in newborns allows the use of the total kidney volume at birth as a surrogate for congenital nephron number. Since the renin-angiotensin system plays an important role in renal development we hypothesized that the common, functional insertion/deletion (I/D) polymorphism in the ACE gene might be responsible for the variation in kidney size amongst healthy individuals. We recruited 210 healthy Polish full-term newborns born to healthy women with uncomplicated pregnancies. The kidney volume was measured sonographically. Total kidney volume (TKV) was calculated as the sum of left kidney volume and right kidney volume. TKV was normalized to body surface area (TKV/BSA). The I and D alleles were identified using polymerase chain reaction. TKV/BSA in newborns carrying at least one insertion ACE allele was significantly reduced by approximately 8% as compared with homozygous newborns for the D allele (DD genotype) (105.1±23.6 vs. 114.2±28.2 cm(3)/m(2), p<0.05). The results of this study suggest that I/D ACE polymorphism may account for subtle variation in kidney size at birth, which reflects congenital nephron endowment.

ABSTRACT

Rhinoscleroma is a chronic inflammatory disease in which granulation tissue with a typical cell content is found. The paper presents the case of a 77-year-old woman with clinically diagnosed nodule in the nasal cavity. The histopathological examination revealed granulation tissue with plasma cells and Mikulicz's cells. The clinical and morphological picture of the case in question is a rare opportunity to bring to mind a disease that used to be common in Poland and which clinically can imitate malignant tumour.

ABSTRACT

The aim of this study was to evaluate associations between seven morphometric parameters of the nucleoli and nuclei of methyl green and pyronin Y (MG-PY) stained tumour cells of invasive ductal breast carcinoma with relapse-free survival (RFS) and overall survival (OS) time. Histological sections from 150 invasive ductal breast cancers were stained with MG-PY and the following parameters were evaluated by computer image analysis: the nucleolar area, long to short nucleolar axis ratio, nucleolar shape parameter assessing the degree of nucleolar roundness, long to short nuclear axis ratio, number of nucleoli in the nucleus and the percentage of the nuclear cross-section surface area occupied by the nucleoli. A statistically significant association between a nucleolar shape polymorphism and the number of nucleoli in the nuclei of tumour cells and the RFS but not OS was found in the entire group of patients as well as patients with axillary lymph node metastases. A higher polymorphism of nucleolar shape and a higher number of nucleoli in the nuclei of breast cancer cells were associated with decreased relapse-free survival (p < 0.05). The remaining morphometric parameters showed no statistically significant association with RFS or OS. The results indicate that morphometry of nucleoli in MG-PY stained histological sections can be useful in the analysis of associations between nucleolar parameters and prognosis of patients with invasive breast cancer.

ABSTRACT

INTRODUCTION: The purpose of this study was to correlate seven morphometric parameters of nucleoli and nuclei of invasive ductal cancer cells with some clinico-pathological factors such as age, tumor size, axillary lymph node status, MIB-1 proliferation index, and estrogen receptor expression in tumor cells. MATERIAL AND METHODS: Methyl green-pyronin Y (MG-PY) was used for simultaneous staining of nuclei and nucleoli in histological sections of 150 invasive ductal breast carcinomas. Next, morphometric parameters of nucleoli and nuclei of tumor cells were measured with computerized image analysis. RESULTS: Nuclear area and number of nucleoli in breast tumor cells were greater in younger axillary node-negative patients. The number of nucleoli and nucleolar shape polymorphism were reduced in tumors measuring 20 mm or less or with lower histological grade. Nuclear area, nucleolar number, and nucleolar polymorphism in carcinomas with low proliferation index and estrogen receptor expression were smaller than in carcinomas with high proliferation index and no estrogen receptor expression. Nucleolar area in primary tumors without axillary node involvement was greater than in tumors with more than three axillary nodes positive. CONCLUSIONS: MG-PY selectively and simultaneously stains nucleoli and nuclei of tumor cells enabling standardized and reproducible examination of these structures with computerized image analysis. Univariate statistical analysis disclosed that some morphometric parameters of nucleoli and nuclei of tumor cells correlated with several established clinico-pathological prognostic factors. Therefore, the prognostic significance of these parameters should be studied in a larger group of patients with invasive ductal breast carcinomas.
