Objective To investigate clinicopathological characteristics, diagnosis and differential diagnosis of primary mucin-producing urothelial-type adenocarcinoma of prostate. Methods We reported a rare case of mucin-producing urothelial-type adenocarcinoma of prostate and reviewed relevant literatures to discuss the clinicopathological features, diagnosis and differential diagnosis. Results In this case, the patient was a 77-year-old male with the history of dysuria. B-ultrasound indicated benign prostatic enlargement and abnormal echogenicity remained to be determined. CT scan and gastrointestinal endoscopy didn't show any evidence of bladder and colorectal tumor. No serum prostate-specific antigen (PSA) increased. The patient underwent laparoscopic radical resection of prostate cancer. Microscopically, the tumor presented as mucinous carcinoma, similar to colorectal mucinous carcinoma, but the migration from the normal prostatic urethra was observed and the urethral epithelium at the transitional site was characterized by adenoepithelial metaplasia and adenocarcinoma in situ. Immunohistochemical staining showed neoplastic cells were diffuse and strongly positive for CK7 and 34βE12, focally positive for CDX-2 and CEA and negative for CK20, β-catenin, GATA3, PSA, PSAP, AR and P504S. Conclusion Mucin-producing urothelial-type adenocarcinoma of prostate is an extremely rare tumor. It has a poor prognosis and it is not sensitive to endocrine therapy.

目的 分析肺肝样腺癌(HAL)的临床病理特征、诊断、免疫表型、基因检测及治疗预后等。方法 对1例HAL临床及影像学、组织学形态、免疫组化及基因检测结果等进行观察,并结合相关文献综合分析。结果 患者为48岁吸烟男性,镜下肿瘤具有肝细胞样和腺样分化特征,血清AFP升高。免疫组化: Hepatocyte,AFP, Arginase-1均阳性,ARMS-PCR法均未检测到EGFR,ALK/ROS1,KRAS及BRAF突变。结合相关文献分析: HAL常见于有吸烟史的男性,血清AFP值升高也是该肿瘤的一个特点。肿物多见于肺上叶,体积较大,易发生淋巴结和远处转移,预后相对较差。结论 HAL非常少见,易误诊,其诊断需结合形态学特点、临床病理特征及免疫组化结果等。

Objective To explore the clinicopathologic characteristics, diagnosis, immunophenotype, gene detection and prognosis of primary hepatoid adenocarcinoma of the lung (HAL). Methods A case of hepatoid adenocarcinoma of the lung was analyzed with clinical manifestations, histology, immunohistochemical staining and gene detection, and relevant literatures were reviewed. Results The patient was a 48-years-old man with smoking history. Microscopically, the tumor has the characteristics of hepatocellular carcinoma and adenoid differentiation, also serum AFP was elevated. The immunohistochemical results showed that Hepatocyte, AFP and Arginase-1were positive. No mutations were detected for EGFR, ALK/ROS1, KRAS and BRAF by ARMS-PCR. Combining with literature analysis, HAL is common in males and most patients with this tumor are smokers. Serum AFP in very high levels has been a distinguishing feature of this tumor. HAL usually presents as a large bulky solitary mass in the upper lobe. Lymph nodes and distant metastases are prone to occur. Therefore, the prognosis is very poor. Conclusion HAL is a rare malignant tumor and easy to be misdiagnosed. The diagnosis of primary hepatoid adenocarcinoma of the lung should be combined with morphological features, clinicopathological features and immunohistochemical findings.

Objective To explore the diagnosis and treatment of primary carnitine deficiency. To identify potential mutation of SLC22A5 gene in two children affected with primary carnitine deficiency and provide genetic counseling. Methods We measured the free camitine(Co)and acylcamitine levels in a suspected clinical inherited metabolic diseases by tandem mass spectrometry. The SLC22A5 gene mutations were tested to the children with low Co level and the diagnosis was made. Then, We measured the free camitine(Co)and acylcamitine levels and SLC22A5 gene mutations in her sister. The children with PCD were treated with carnitine and followed up for 11 months. The SLC22A5 gene was detected in their family. Results In two children affected with PCD, 1 case was clinical children, another case of their sister was no obvious clinical manifestations. Mutations were found in all of them.The average C0 level in patients was lower than the reference value,along with decreased level of different acylcamitines. Two cases were treated with earnitine. Their clinical symptoms reduced 2 months later. Another case had not been sick. The CO level and different acylcamitines level in the blood rose to normal. A homozygous mutation C. 760C>T (P. Arg254X)of the SLC22A5 gene was detected in the two cases.Heterozygous mutation C. 760C>T (P.Arg254X) was also found in other family members. Conclusion Two patients were diagnosed with PCD by the test levels of free carnitine and acylcarnitines in blood with tandem mass spectrometry,and gene mutation test. L-carnitine supplement had a good effect in treatment of the PCD patients.C.760C> T (P.Arg254X) mutations of the SLC22A5 gene is the deleterious mutations for PCD families, The analysis method of the wrong mutagenesis and shear changes which is used to directly sequence the exons codes of the SLC22A5 gene can provide genetic counseling for PCD families.

Objective To investigate the diagnosis and treatment of primary splenic tumor. Methods The clinical data of 58 patients with primary splenic tumor from January 2006 to December 2014 were retrospectively analyzed. Results 45 cases were benign splenic tumor, including 21 hemangioma, 11 splenic cyst, 8 lymphangioma, 3 littoral cell angioma, 1 hamartoma and 1 sclerosing angiomatoid nodular transformation of spleen. 13 cases were malignant splenic tumor, including 12 lymphoma and 1 angiosarcoma. Ultrasound and CT were the main diagnostic methods. 51 cases underwent splenectomy, including 23 open splenectomy and 28 laparoscopic splenectomy. 5 cases underwent partial splenectomy and 2 splenectomy combined distal pancreatectomy. There had no postoperative complications. The follow-up period was 9 months to 9 years. 41 cases with benign splenic tumor had no recurrence or metastasis. The 1-, 3-, 5-years survival rate were 81.8%, 63.6% and 27.2% respectively of 11 patients with malignant splenic tumor. Conclusion The diagnostic of primary splenic tumor mostly rely on clinical features and imagic examination. Surgical resection is not only an effective treatment, but also a confirmed diagnosis method for primary splenic tumor. Partial splenectomy is a reasonable procedure for local benign splenic tumor. Early surgery, combined adjuvant chemotherapy and radiotherapy are important for improving the prognosis of malignant splenic tumor.
