ABSTRACT
BACKGROUND: Cervical squamous cell carcinoma (SCC) is the most common type of cervical carcinoma and is generally derived from a precancerous stage called cervical high-grade squamous intraepithelial lesion (HSIL). Usually, the cancer metastasizes through lymphatic or hematogenous dissemination, but rarely spreads upward into the uterus. Here, we report a case of cervical HSIL extending into the endometrium and finally progressing to SCC in the uterine cavity. CASE SUMMARY: A 57-year-old postmenopausal woman visited our department and requested a routine cervical check-up. Four years ago, she had undergone a cervical loop electrosurgical excision procedure because of HSIL found during the gynecological examination, and she had not been checked again since. This time, a relapse of the cervical HSIL was diagnosed along with uterine pyometra and endometrial polyps. After 2 wk of antibiotic treatment, a laparoscopic hysterectomy was performed, and the final pathological examination revealed that the cervical HSIL had spread directly upward into the uterine cavity, gradually developing into cervical SCC in the endometrium. CONCLUSION: Cervical HSIL/SCC can directly spread upward into the uterus with the most common symptoms of pyometra and cervical stenosis. More attention should be given to the early detection and prevention of this disease.
ABSTRACT
BACKGROUND: Uterine myoma is the most common benign tumor among women and is often accompanied by anemia. Here, we report the case of a patient with a very large leiomyoma but with a hemoglobin level as high as 197 g/L. After undergoing hysterectomy, all her hematological parameters returned to normal. Immunohistochemical staining of her myoma for erythropoietin showed strong positivity, which suggested that erythropoietin may be the cause of her erythrocytosis. A multidisciplinary team played a significant role in treating the disease. CASE SUMMARY: A 47-year-old woman visited our department complaining that her abdomen had been continuously growing for the past 2 years. After careful examinations, she was suspected of having a very large leiomyoma. She was also diagnosed with erythrocytosis because her RBC count was 6.49 × 1012/L, hemoglobin was 197 g/L. Following a multidisciplinary team consultation, bilateral ureteral stents were placed, and 800 mL blood was removed by phlebotomy. The patient then underwent hysterectomy and bilateral salpingectomy. She recovered well from the operation, and her hemoglobin level decreased sharply following the surgery. Low-molecular-weight heparin was administered daily to prevent postoperative thrombosis. She was discharged from the hospital on the fourth postoperative day. Two months later, all her hematological parameters returned to normal. Pathological analysis of the myoma revealed that it was a benign leiomyoma, with partial hyalinization, and strong positivity for erythropoietin in immunohistochemical staining suggested that erythropoietin may be responsible for the erythrocytosis. CONCLUSION: Erythropoietin ectopically produced from the myoma was responsible for the erythrocytosis in this patient. A multidisciplinary team is strongly recommended.
ABSTRACT
OBJECTIVES@#To detect the genotype of ABO blood group by SNaPshot technology.@*METHODS@#DNA were extracted from the peripheral blood samples with known blood groups （obtained by serology） of 107 unrelated individuals in Yunnan. Six SNP loci of the 261th, 297th, 681th, 703th, 802th, and 803th nucleotide positions were detected by SNaPshot Multiplex kit, and relevant genetics parameters were calculated.@*RESULTS@#In 107 blood samples, the allele frequencies of types A, B, OA, and OG were 0.355 1, 0.168 2, 0.230 0 and 0.247 6, respectively, while that of types AG and cis AB were not detected. The genotyping results of ABO blood group were consistent with that of serologic testing.@*CONCLUSIONS@#SNaPshot technology can be adapted for genotyping of ABO blood group.
