Endocervical Atypical Polypoid Adenomyoma

Immunohistochemical results and case report of an incidental finding of uterine polypoid adenomyoma after long-time therapy for metrorrhagia

We present a 25-year-old female woman with a 9-year history of metrorrhagia, in whom a uterine polypoid adenomyoma (UPA) was incidentally detected. Intense nuclear staining in the uterine adenomyoma tissue showed an immunoreaction with BAF250a/ARID1A, Arginase-2 as well as 1LRH-2E1/NR5A2, suggesting a role of these proteins and transcriptional activity of their genes in uterine polypoid adenomyoma development. Neither Nidogen-2 nor SF-1/NR5A1 were expressed in UPA.

Adenomyomas of the Uterine Cervix in the First-Trimester of Pregnancy: A Case Report

Cervical adenomyomas of endocervical type (endocervical adenomyomas) are very rare benign lesions. Here we report the case of a 33-year-old woman who referred to the Perinatology Clinic of Ommolbanin Hospital (Mashhad, Iran) in September 2017. The patient was 8 weeks pregnant and complained of spotting and feeling a mass protruding from her vagina for 2 months. Physical examination revealed the presence of three masses of approximately 10 cm in the vagina, which were treated surgically. Histopathological examination of the excised specimen showed the presence of glands lined by a single layer of endocervical-type mucinous epithelium with smooth muscle fibers. Clinicians should be aware of such lesions in order to differentiate them from other malignancies and to individualize treatment.
