Objective To summarize the diagnostic experiences of blastic plasmacytoid dendritic cell neoplasm (BPDCN) based on the study of its clinicopathological features and immunophenotypes. Methods The clinical data of 2 patients with BPDCN were collected, the structure alteration and cell morphology were observed by HE staining, the immunophenotype of tumor cells were studied by immunohistochemistry staining and flow cytometry was adopted to confirm the bone marrow involvement. Results Two patients, one of whom was a 97 year-old female, presented with cutaneous ecchymosis nodules as the first symptom. The epidermis, but not the dermal, was diffusedly infiltrated by tumor cells, which were medium-sized with irregular nuclei without prominent nucleoli. The other case was a 69 year-old male with lymph node enlargement as the first symptom. The skin was normal, but the lymph nodes were invasively destroyed by tumor cells, which were medium-sized blast-like with prominent nucleoli. The immunophenotypes of the two patients were both positive for CD123, CD4, CD56 and TDT, but negative for B, T lymphocyte derived and myeloid origin markers, both of which involved bone marrow. Conclusions BPDCN is a rare form of hematological neoplasm, skin symptoms or lymph node enlargement may be presented as the initial symptom, the clinical course were highly aggressive with high frequency of bone marrow involvement. The blastic-like lymphoma and leukemia entities should be considered into account for differential diagnose. The precise diagnosis of BPDCN should be established by integrating histomorphology, immunophenotype and clinical presentation information comprehensively.

Objective To analyze and compare the clinical features of patients with pulmonary involvement of Whipple disease and primary treated bacteriological negative pulmonary tuberculosis,so as to improve the recognition,diagnosis and differentiation ability of pulmonary involvement of Whipple disease．Methods Clinical features of Whipple disease with pulmonary involvement were investigated by retrospectively collecting 20 cases as a case group,comparing with 56 randomly selected patients with primary treated bacteriological negative pulmonary tuberculosis as a control group during the same period．Results The case group had a significantly higher proportion of older patients（>37 years）,acute or subacute disease courses than the control group （P<0.05）．On CT imaging,in terms of lesion distribution,the proportion of cases with lesions in the lower lobe was significantly more in the case group than in the control group（P<0.05）,and the ratio of cases with lesions in the upper lobe was considerably less than in the control group（P<0.05）．Regarding morphology,significantly more of the case group showed reticular lesions and interstitial pneumonia than the control group（P<0.05）．Significantly fewer of the case group showed cavities,fibrous bands,solid shadows,nodular shadows,tree-bud signs,and enlarged hilar lymph nodes than the control group（P<0.05）．No statistically significant differences existed between the two groups in gender,combined immunocompromising diseases,cough,sputum,fever,coughing up blood,arthralgia or diarrhea. At the same time,the differences of gender,combined immunocompromised disease,cough,sputum,fever,coughing up blood,arthralgia,and diarrhea were not statistically significant．The metagenomic sequencing of alveolar lavage fluid in the case group revealed Tropheryma whipplei as the sole pathogenic bacteria in 19 cases（95%）or the primary pathogenic bacteria in 1 case（5.00%,combined TB 1 sequence）．In contrast,metagenomic sequencing of alveolar lavage fluid in the control group detected Mycobacterium tuberculosis complex as the sole or primary pathogenic bacteria in 21 cases（37.5%）,TB-RNA（+）in 18 cases and TB-LAMP（+）in 15 cases．Conclusions Clinical presentation in Whipple disease can be of an acute or subacute course,preferably in middle-aged and older men,with fever or/and respiratory symptoms,either with or without diarrhea and arthralgia．Its pulmonary imaging dominates with reticular,interstitial pneumonia changes in the lower lungs,which can involve the lungs alone in the disease．At the same time,the clinical symptoms are highly similar to those patients with primary treated bacteriological negative pulmonary tuberculosis．Therefore,it is vital to complete bronchoscopy and metagenomic sequencing of alveolar lavage fluid as soon as possible for early and rapid diagnosis of this Whipple disease．Treatment with sensitive antibacterial drugs can result in significant improvement and save patients' lives．

Objective To investigate the composition and clinicopathological features of endometrial carcinoma．Methods A total of 82 cases of endometrial carcinoma patients admitted to the First Hospital of Nanping City from January 2020 to June 2022 were studied．Epidemiological data were collected,and the expression of 4 mismatch repair proteins were detected by immunohistochemical staining,and their relationship with clinicopathological features was analyzed．Results Among 82 patients,70 cases（85.37%）were endometrioid carcinoma,and 30 cases（42.86%）were mainly G1 grade,other types were rare．The total deletion rate of mismatch repair proteins expression was 35.71%,in which MLH1 alone was 2.86%,MSH2 was 4.29%,MSH6 was14.29% and PMS2 was14.29%．The proportions of dMMR patients over 50 years old,with vascular invasion and lymph node metastasis,G3 grade histology and FIGO stage Ⅲ were significantly higher than those of the pMMR group（P<0.05）．The loss of MSH6 protein expression was more likely to occur in patients over 50 years old with a family history of related diseases（P<0.05）．The deletion of PMS2 protein expression was more likely to occur in patients with histological G2 grade,FIGO stage III,pregnancy of once or more and intravascular cancer thrombin and lymph node metastasis（P<0.05）．Conclusions The expression of mismatch repair proteins in endometrial carcinoma is closely related to some clinicopathological features,which provides valuable guidance for follow-up treatment．
