Rare Skin Adnexal and Melanocytic Tumors Arising in Ovarian Mature Cystic Teratomas: A Report of 3 Cases and Review of the Literature

Abstract

Mature teratoma of the ovary is the most common primary ovarian tumor accounting for 15% (10%-20%) of all ovarian neoplasms. Skin and skin adnexal structures are the most common elements identified in mature teratomas. Benign and malignant skin tumors can arise in ovarian teratomas, the most common being epithelial tumors. Melanocytic and adnexal tumors developing in a teratoma are rare and can be easily overlooked. We report 3 cases and review melanocytic and skin adnexal tumors encountered in ovarian teratomas.

Trichoblastic Carcinosarcoma Arising From the Vagina: A Case Report With Comprehensive Immunophenotypic Analysis

“…17 However, in our case, the tumor was located in the upper vagina without evidence of vulval/perineal skin connection on clinical examination, magnetic resonance imaging, or surgical exploration. Cutaneous adnexal tumors are also observed to develop from ovarian teratomas, 18 but no ovarian pathology was seen in our case. As such, this case most likely represents a trichoblastic carcinosarcoma of vaginal origin.…”
