Munson's sign is a V-shaped indentation observed in the lower eyelid when the patient's gaze is directed downwards. The medical sign is characteristic of advanced cases of keratoconus and is caused by the cone-shaped cornea pressing down into the eyelid.
Inflammatory ulcers in the mouth, genitalia, and skin are the hallmark of Behcet's disease (BD), a multisystem illness that is chronic and relapsing. [2] Autoimmune recurrent chondritis of the larynx, tracheobronchial tree, nose, ears, and mouth is known as relapsing polychondritis (RP).
Diagramatic representation of mucosal erosion (left), excoriation (center), and ulceration (right) Simplistic representation of the life cycle of mouth ulcers. An ulcer (/ ˈ ʌ l s ər /; from Latin ulcus, "ulcer, sore") [2] is a break in the skin or mucous membrane with loss of surface tissue and the disintegration and necrosis of epithelial tissue. [3]
Smokeless tobacco keratosis (STK) [4] is a condition which develops on the oral mucosa (the lining of the mouth) in response to smokeless tobacco use. Generally it appears as a white patch, located at the point where the tobacco is held in the mouth. The condition usually disappears once the tobacco habit is stopped.
A highly pronounced cone can create a V-shaped indentation in the lower eyelid when the person's gaze is directed downwards, known as Munson's sign. [14] Other clinical signs of keratoconus will normally have presented themselves long before Munson's sign becomes apparent, [ 46 ] and so this finding, though a classic sign of the disease, tends ...
The individual ulcers (aphthae) recur periodically and heal completely, although in the more severe forms, new ulcers may appear in other parts of the mouth before the old ones have finished healing. Aphthous stomatitis is one of the most common diseases of the oral mucosa , and is thought to affect about 20% of the general population to some ...
Corneal topography may show a "crab claw-like" appearance, a finding that is seen in both keratoconus and in pellucid marginal degeneration. Thus, if corneal topography is used for diagnosis, it should be in conjunction with clinical findings of peripheral, inferior corneal thinning. [8]
In progress, but mostly complete. (Would be nice to know who coined the term keratoconus.) Consider changing the title of "Diagnosis" to "Signs" or "Signs and Diagnosis", then merge the section entitled "Possible complications" with it. Done. Consider adding mention of Munson's sign in signs/diagnosis section. Done
