The application value of transrectal ultrasonography in the diagnosis of anorectal malignant melanoma / 中华超声影像学杂志

Objective@#To investigate the value of transrectal ultrasonography(TRUS) in the preoperative diagnosis and tumor T-staging of anorectal malignant melanoma(ARMM).@*Methods@#The clinical and ultrasound data of 19 patients(22 lesions) with ARMM confirmed by pathology from February 2008 to Apirl 2019 in Fujian Medical University Affiliated Union Hospital were collected. TRUS was performed within one week before pathological examination. The sonographic features were summarized, ultrasonic typing was performed according to the lesion size and growth pattern, and the accuracies of preoperative ultrasound diagnosis and tumor staging were analyzed.@*Results@#Among the 22 lesions, 63.64%(14/22) were with a distance of ≤3 cm between the anal verge and the lower margin of tumor, 68.18%(15/22) with regular shape, 81.82%(18/22) with clear boundary, and 63.64%(14/22) with Adler blood flow grading from Ⅱ to Ⅲ. The preoperative TRUS diagnostic coincidence rate was 73.68%(14/19), and the tumor T-staging accuracy was 75%(12/16), respectively.@*Conclusions@#TRUS exhibits certain sonographic characteristics, with high preoperative diagnosis rate and tumor T-staging accuracy in anorectal malignant melanoma, which is of great guiding significance for clinical diagnosis and treatment.

Diagnosis and treatment of anorectal malignant melanoma / 中国普通外科杂志

ObjectiveTo determine the clinicopathological characteristics, the diagnosis, treatment and prognosis of anorectal malignant melanoma. MethodsRetrospective analysis was unducted for the clinical manifestation,treatment and prognosis of11 cases of anorectal malignant melanoma confirmed by surgery and pathology from 1978 to 1999. Results Of the 11 patients,7 had hematochezia of various degrees and suffered pain surrounding the auns.Seven patients had been misdiagnosed before the operation.The median survival time was 18 months,the longest survivor 39 months.ConclusionsAnorectal malignant melanoma is a highly malignant with early metastasis and poor prognosis.Radical surgery combined with chemotherapy,immunotherapy and biotherapy may be more effective.
