A dermoid cyst is a teratoma of a cystic nature that contains an array of developmentally mature, solid tissues. It frequently consists of skin, hair follicles, and sweat glands, while other commonly found components include clumps of long hair, pockets of sebum, blood, fat, bone, nail, teeth, eyes, cartilage, and thyroid tissue.
Simple, smooth ovarian cysts, smaller than 3 cm and apparently filled with water, are considered normal. [8] Large cysts that cause problems occur in about 8% of women before menopause. [1] Ovarian cysts are present in about 16% of women after menopause, and have a higher risk of being cancer than in younger women.
A small (4 cm) dermoid cyst of an ovary, discovered during cesarean section: Specialty: Gynecology, oncology: Symptoms: Minimal, painless lump [1] [2] Complications: Ovarian torsion, testicular torsion, hydrops fetalis [1] [2] [3] Types: Mature, immature [4] Causes: Unknown [2] Diagnostic method: Tissue biopsy [2] Differential diagnosis: Lipoma ...
A teratoma is a tumor of germ cell origin, containing tissues from more than one germ cell line, [2] [3] [4] It can be ovarian or testicular in its origin. [4] and are almost always benign. [5] An immature teratoma is thus a very rare tumor, representing 1% of all teratomas, 1% of all ovarian cancers, and 35.6% of malignant ovarian germ cell ...
Ovarian cysts such as theca lutein cysts can cause ovarian torsion. Torsion occurs when the cysts enlarge the ovaries, causing an imbalance resulting in the twisting of the fallopian tubes. [25] As a result, blood flow to the ovaries is restricted which can cause infarction of the tissue. This requires prompt surgical treatment. [25]
It is common for many women to develop a cyst in their lifetime. [4] At times, these can go unnoticed without pain or visible symptoms. A cyst may develop in either of the ovaries that are responsible for producing hormones and carrying eggs. Ovarian cysts can be of various types, such as dermoid cysts, endometrioma cysts, and the functional cyst.
A struma ovarii (literally: goitre of the ovary) is a rare form of monodermal teratoma that contains mostly thyroid tissue, which may cause hyperthyroidism. [1]Despite its name, struma ovarii is not restricted to the ovary.
Teratoma are most common germ cell tumor of ovary. Teratomas can be divided into two types: mature teratoma (benign) and immature teratoma (malignant). Immature teratomas contain immature or embryonic tissue which significantly differentiates them from mature teratomas as they carry dermoid cysts. [5]
