Fixation

Generally 10% neutral buffered formalin.

Gross processing

Example gross report:

(Optionally: A. Labeled - Left dermoid cyst. The specimen is received in formalin and consists of) tan-pink to yellow cystic ovarian tissue measuring __ cm. The cyst lining reveals multiple patches of hair with associated greasy yellow keratinous material. Cross-sections show several plate-like areas of rubbery grey-white cartilage. Representative sections are submitted for microscopic examination in one cassette.

Microscopic evaluation

Dermoid cyst, showing components from several germ layers.

The diagnostic criterion is a well-differentiated components from at least two germ layers (ectoderm, mesoderm and/or endoderm).[1] Common representative tissues of these are:

  • Ectoderm: Epidermis, eppidermal appendages, nervous tissue (neuroectoderm)
  • Mesoderm: connective tissue, striated muslce, smooth muscle, cartilage
  • Endoderm: Respiratory epithelium, thyroid tissue, gastrointestinal mucosa
