Synchronous Superficial Myofibroblastoma and Stromal polyp of the Vagina: Report of A Case Supporting Common Histogenesis of Both Lesions

Abstract

Rare simultaneous occurrence of vaginal superficial cervicovaginal myofibroblastoma and vaginal stromal polyp is described. The lesions were found in a 90-years-old patient, in the anterior wall of the vagina. The diameter of the lesions was 6cm and 2cm, respectively. Between them, a 3cm part of normal appearing vaginal wall was present. Both lesions showed similar myoid appearing morphology and myofibroblastic desmin+/actin-/h-caldesmon-/CD34- immunophenotype, with positivity for CD10, CD99, estrogen receptor and progesterone receptor. Larger lesion was diagnosed as benign cervicovaginal myofibroblastoma, and the smaller one had typical features of vaginal stromal polyp. This case of simultaneous occurrence of cervicovaginal myofibroblastoma and vaginal stromal polyp supports previously suggested histogenetic relationship between these lesions.
