Dermoid cystTheca lutein cyst: A Theca lutein cyst is a type of bilateral functional ovarian cyst filled with clear, straw-colored fluid. To be classified a functional cyst, the mass must reach a diameter of at least three centimeters.Median mandibular cyst: A median mandibular cyst is a type of cyst that occurs in the midline of the mandible, thought to be created by proliferation and cystic degeneration of resting epithelial tissue that is left trapped within the substance of the bone during embryologic fusion of the two halves of the mandible, along the plane of fusion later termed the symphysis menti. A ture median mandibular cyst would therefore be classified as a non-odontogenic, fissural cyst.Dark FieldsOrbital lymphoma: Orbital lymphoma is a common type of non-Hodgkin lymphoma that occurs near or on the eye. Common symptoms include decreased vision and uveitis.Sebaceous cystBlepharitisFontanelle: A fontanelle (or fontanel) (colloquially, soft spot) is an anatomical feature of the infant human skull comprising any of the soft membranous gaps (sutures) between the cranial bones that make up the calvaria of a fetus or an infant. Fontanelles allow for rapid stretching and deformation of the neurocranium as the brain expands faster than the surrounding bone can grow.Splenic flexure syndrome: Splenic flexure syndrome is a term sometimes used to describe bloating, muscle spasms of the colon, and upper abdominal discomfort thought to be caused by trapped gas at the splenic (as opposed to hepatic) flexure in the colon; the pain caused can be excruciating and debilitating, and may mimic that of a heart attack (because of the proximity of the splenic flexure to the diaphragm and referred pain from irritation to the diaphragmatic sensory nerves).
