ABSTRACT
Objective To investigate the clinical pathological characteristics, diagnosis and treatment of breast rhabdomyosarcoma, and to enhance the awareness of malignancy infiltration to bone marrow (BM). Methods The data of one case of Rhabdomyosarcoma of breast were analyzed retrospectively. BM aspirate and biopsy, morphology, immunology, cytogenetics, molecular biology (MICM) in different parts of BM, peripheral blood smear, fine puncture of breast mass, final biopsy of breast mass by Mammotome System and whole body PET-CT were performed. The immunochemistry stain of specimen of breast mass was used. Results The peripheral blood smear of this patient showed immature erythrocytes, leucocytes and classification of unknown cells which were consistent with BM morphology. The results of BM aspirate and biopsy depicted a hypercellular specimen with disseminated unknown cells infiltration. Unknown cells were positive for CD56 and negative for any hematopoietic markers by flow cytometry. The whole body PET-CT showed that uptake of 18F-FDG of bilateral breast and whole BM was increased, whereas the mass of breast was not presented by CT. PET-CT suggested a probable malignant hematologic disease. The enough specimen of breast mass got from Mammotome System showed embryonal rhabdomyosarcoma, and the tumor cells were positive for MyoD1, Vimentin and Desmin. Conclusions It is a challenge for early diagnosis of solid sarcoma with unknown origin which diffusely infiltrating into BM. Negative expression of hematopoietic markers by flow cytometry plays a role on differential diagnosis in this setting, whereas PET-CT only provides a valuable reference. Enough specimen and immunohistochemical staining could provide solid evidences of diagnosis.
ABSTRACT
Objective To investigate the clinical significance of gastric cracks by investigating the relationship between stomach cracks under gastroscopy and H.pylori infection as well as its pathological manifestation,in order to improve the detection rate of H.pylori.Methods Gastroscopy patients were enrolled as our subjects excluding those with tumors,major diseases and under 18 years old.Mucosal biopsies were obtained from the lesser curvature of antrum and the greater curvature of body in each patient,then by HE staining,pathological and HP examination.The information including the pathological diagnosis,HP antibody,rapid urease test,endoscopic diagnosis and endoscopic gastric body cracking phenomenon were collected from all patient.H.pylori positivity was defined as a patient who showed two or more positive results in the Rapid Urea's Test,pathohistological examination and H.pylori antibody detection.Results (1) 437 patients with gastroscopy were included between December 2009 and December 2011,among whom 210 were male and 227 were female.There were 32 cases with gastric ulcer,59 cases with duodenal ulcer,51 cases with duodenitis,62 cases with reflux esophagitis,and 276 cases with chronic gastritis.(2) H.pylori distribution in stoma of all patients:160 of 437 patients(36.61％) are H.pylori positive,of which 68.75％ (110/160) was found H.pylori positive in both of gastric antrum and body,25.63％ (41/160) was H.pylori positive only in antrum,and 3.13％ (5/160) was H.pylori positive only in the body of stomach.(3)Relationship between the presence of cracks in gastric body and H.pylori infection:the H.pylori positivity was 62.58％ (97/155) and 22.34％ (63/282) respectively in the group with or without the presence of cracks in body.Cracks in gastric body examined by gastroscopy was related to H.pylori infection(x2 =69.788,P =0.000).(4) Relationship between the presence of cracks in gastric body and patho-histology:the presence of cracks in gastric body was related with severity of gastric inflammation by Wilcoxon rank sum test (P ＜ 0.0001),while there was no relationship between gastric body cracks and atrophy,intestinal metaplasia and atypical hyperplasia(P ＞ 0.05).(5) Relationship between the presence of cracks in gastric body and diseases:the presence of cracks in body was related with duodenitis,bile reflux under gastroscopy while there was no difference among in gastric body and gastric ulcer,esophagitis and chronic gastritis in terms of cracking appearance (P ＞ 0.05).Conclusion Our finding showed that cracking appearance in the gastric body is related with severity of inflammation in gastric mucosa bile reflux and duodenitis,suggesting that it can be one of the gastroscopic manifestations of more severe gastritis.
ABSTRACT
Objective To investigate the pathohistologic features and grading of biopsy mucosae and their correlation with disease severity of active ulcerative colitis(UC). Methods A prospective study was conducted in 133 patients with UC who were divided into three groups based on the degree of severity. Pathologic morphometry and grading with HE staining sections were analyzed. Results Pathologic features of active UC: there were neutrophilic leukocytes (100.0%), eosinophils (99.2%), plasmacytes(91.7%) and lymphocytes (75.2%) infiltration among mucosal epithelial cells, and lymphoid follicular formation(72.2%) and small vessels inflammation(63.9%) and focal hemorrhage(68.4%) in lamina propria. There were crypt abscesses(43.6%), glandular abnormalities (44.4%), goblet cell depletion (18.8%), epithelial cell regeneration (36.8%) , atypical hyperplasia (28.6%) and granulation tissue formation (42.9%) in mucosae. With the increase of severity of UC, there was a significant increasing incidence of small vessel inflammation, fiberoid necrosis of vessel wall, glandular abnormality, epithelial cell regeneration, atypical hyperplasia, goblet cell depletion, granulation tissue formation, fiber tissue hyperplasia, and crypt abscess. There was no significant difference of the incidence of lymphocyte hyperplasia, lymphoid follicular formation, eosinophil and plasmacyte infiltration between the groups. Mild UC was mainly characterized by the lesions of Grade Ⅰ and Ⅱ, moderate UC by those of Grade Ⅱ and Ⅲ and severe UC by those of Grade Ⅲ and Ⅳ. There were significant differences of grades among mild, moderate and severe UC. Conclusions There were some pathologic characters in active UC. The partial of markers and histological gradings can reflect the severity and activity of active UC.

ABSTRACT
The people died from H5N1 avian influenza virus,which was diagnosed by serological test.The remarkable pathohistology change is as follows:thick and homogeneous things dyed red can be seen on the face of pulmonary alveoli;the alveolar septum become wider and there are a lot of inflammatory cells in the pulmonary alveoli.Above all,we think that the histology changes can provide evidence to help coroners identify people died from H5N1 avian influenza virus or not.
