Malignant Melanoma Arising in an Ovarian Mature Cystic Teratoma - A Rare Entity
Mature cystic teratomas, also known as dermoid cysts, are composed of a mixture of tissues derived from all three germ layers and constitute about 20% of all ovarian neoplasms. However, malignant transformation in a mature cystic teratoma is an uncommon event occurring only in about 1.8% cases. A...

| description | Mature cystic teratomas, also known as dermoid cysts, are composed of a mixture of tissues derived from all three germ layers and
constitute about 20% of all ovarian neoplasms. However, malignant transformation in a mature cystic teratoma is an uncommon event
occurring only in about 1.8% cases. A variety of tumours can arise within a mature cystic teratoma (most common being squamous
cell carcinoma), with malignant melanoma being extremely rare among such tumors. While most authors believe that primary ovarian
melanoma almost always arises within a mature cystic teratoma, the primary nature of an ovarian malignant melanoma can be ascertained
only once metastasis from a cutaneous melanoma is ruled out. The first case of malignant melanoma arising in an ovarian mature cystic
teratoma was reported in 1901 and only about 45 additional cases have been reported till date. We present another case of a primary
malignant melanoma arising within a mature cystic teratoma. |
