This was 83 year old lady diagnosed as carcinoma of cervix with pyometra  and Ovarian dermoid cyst.

Dermoid cyst present between 20 to 40 years of age.

The term dermoid cyst can be found in the vocabulary of dermatologists, dermatopathologists, general pathologists, gynecologists, neurosurgeons, or pediatricians. If asked, all of these clinicians would most probably define and describe dermoid cysts differently. For example, gynecologists and general pathologists would say that a dermoid cyst is associated primarily with a cystic tumor of the ovary. In contrast, neurosurgeons would say that a dermoid cyst is associated with a congenital cyst of the spine or an intracranial congential cyst. For pediatricians and dermatologists, dermoid cyst means subcutaneouscysts, which are usually congenital.

In all disciplines, however, the common factor is the presence of a solitary, or occasionally multiple, hamartomatous tumor. The tumor is covered by a thick dermis like wall that contains multiple sebaceous glands and almost all skin adnexa. Hairs and large amounts of fatty masses cover poorly to fully differentiated structures derived from the ectoderm.

Depending on the location of the lesion, dermoid cysts may contain substances such as nails and dental, cartilagelike, and bonelike structures. If limited to the skin or subcutaneous tissue, dermoid cysts are thin-walled tumors that contain different amounts of fatty masses; occasionally, they contain horny massesand hairs.
