cyst is one of the most common benign ovarian neoplasms that can be
found in different age groups and in various sizes. It is important to
diagnose and treat this problem as soon as possible because of its
complications especially malignancy transformation.</div><div><b>Abstract</b> :</div><div>Mature ovarian cystic teratoma, also known as the dermoid cyst, is one
of the most common benign ovarian neoplasms that can occur in different
age groups and could appear in various sizes. Diagnosing this problem as
soon as possible is essential due to complications that can coincide,
such as malignant transformation. In this article, we reported a 66
years old female patient with a single huge mature ovarian cyst teratoma
who presented to the surgical ward with abdominal pain and swelling but
disregarded it for four years.</div><div><b>Introduction</b> :</div><div>One of the most common benign ovarian neoplasms derived from germ cells
is mature ovarian cystic teratomas, also known as dermoid cysts [1,
2]. Variable proportions of tissues compose these types of cysts,
which originate from the ectoderm, mesoderm, and endoderm [2].
Although, this type of cystic disease is usually seen in the active
reproductive period of women’s lives, but it can be seen in any age
groups, even in the postmenopausal period [3].</div><div>Due to advances in imaging techniques, especially ultrasonography,
diagnosing this disease is much easier today, and finding cysts larger
than 10 cm is very rare [2,4,5]. In this article, we report a huge
mature ovarian cystic teratoma developed in less than four years in a 66
years old postmenstrual female.</div>
