Tumors of cancer of the EYELIDS.
Eyelid diseases refer to various medical conditions that affect the function, structure, or appearance of the eyelids, including inflammatory, infectious, neoplastic, congenital, and traumatic disorders, which can impact vision, comfort, and overall ocular health.
Plastic surgery of the eyelid. (Cline et al., Dictionary of Visual Science, 4th ed)
Reflex closure of the eyelid occurring as a result of classical conditioning.
A malignant tumor composed of cells showing differentiation toward sebaceous epithelium. The tumor is solitary, firm, somewhat raised, more or less translucent, and covered with normal or slightly verrucose epidermis. It may be yellow or orange. The face and scalp are the commonest sites. The growth can be slow or rapid but metastasis is uncommon. Surgery cures most of the cases. (From Rook et al., Textbook of Dermatology, 4th ed, pp2403-4)
Drooping of the upper lid due to deficient development or paralysis of the levator palpebrae muscle.
The turning outward (eversion) of the edge of the eyelid, resulting in the exposure of the palpebral conjunctiva. (Dorland, 27th ed)
Inflammation of the eyelids.
Tumors or cancer of the PANCREAS. Depending on the types of ISLET CELLS present in the tumors, various hormones can be secreted: GLUCAGON from PANCREATIC ALPHA CELLS; INSULIN from PANCREATIC BETA CELLS; and SOMATOSTATIN from the SOMATOSTATIN-SECRETING CELLS. Most are malignant except the insulin-producing tumors (INSULINOMA).
New abnormal growth of tissue. Malignant neoplasms show a greater degree of anaplasia and have the properties of invasion and metastasis, compared to benign neoplasms.
Sebaceous gland neoplasms are uncommon cutaneous tumors that originate from the sebaceous glands, which can be benign (e.g., seborrheic keratosis, syringoma, trichofolliculoma) or malignant (e.g., sebaceous carcinoma, sebaceomatosis, mucoepidermoid carcinoma).
Neoplasms containing cyst-like formations or producing mucin or serum.
Sweat gland neoplasms are abnormal growths that can be benign or malignant, originating from the sweat glands (eccrine or apocrine) and found anywhere on the skin surface.
The muscles that move the eye. Included in this group are the medial rectus, lateral rectus, superior rectus, inferior rectus, inferior oblique, superior oblique, musculus orbitalis, and levator palpebrae superioris.
Tumors or cancer of the SKIN.
The sebaceous glands situated on the inner surface of the eyelids between the tarsal plates and CONJUNCTIVA.
A cystic form of sweat gland adenoma (ADENOMA, SWEAT GLAND). It is produced by the cystic proliferation of apocrine secretory glands. It is not uncommon, occurring in adult life in no particular age group, with males and females equally affected. The commonest site is around the eye, particularly lateral to the outer canthus. It is cured by surgical removal. (Stedman, 25th ed; Rook et al., Textbook of Dermatology, 4th ed, p2410)
The turning inward (inversion) of the edge of the eyelid, with the tarsal cartilage turned inward toward the eyeball. (Dorland, 27th ed)
Two or more abnormal growths of tissue occurring simultaneously and presumed to be of separate origin. The neoplasms may be histologically the same or different, and may be found in the same or different sites.
Excessive winking; tonic or clonic spasm of the orbicularis oculi muscle.
The hairs which project from the edges of the EYELIDS.
Surgery performed on the eye or any of its parts.
