#Telangiectasis.# #Describe telangiectasis.# Telangiectasis consists of a new growth or enlargement of the cutaneous capillaries, usually appearing during middle adult life, and seated, for the most part, about the face. #To what extent may telangiectasis develop?# It may be limited to a red dot or point, with several small radiating capillaries (_naevus araneus_, _spider naevus_), or a whole region, usually the face, may show numerous scattered or closely-set capillary enlargements or new formations (_rosacea_). The latter is frequently associated with acne (_acne rosacea_). The etiology is obscure. #What is the treatment of telangiectasis?# Destruction of the vessels by electrolysis or by the knife. (See treatment of acne rosacea.) #Lymphangioma.# (_Synonym:_ Lymphangiectodes.) #Describe lymphangioma.# Lymphangioma is a rare disease, consisting of localized dilatations of the lymphatic vessels, appearing as discrete or aggregated pin-head or pea-sized, compressible, hollow, tubercle-like elevations, of a pinkish or faint lilac color, and occurring for the most part about the trunk. It is of slow but usually progressive development, and is unaccompanied by subjective symptoms. A rare condition, Kaposi described as lymphangioma tuberosum multiplex, characterized by more or less solid, somewhat cystic, pearly to pinkish red, sometimes crowded lesions, is now known to be "benign cystic epithelioma"; its most common site is the face. While called "benign," ulcerative action may eventually ensue. Treatment, when demanded, consists of operative measures. #Rhinoscleroma.# #Describe rhinoscleroma.# Rhinoscleroma is a rare and obscure disease, slow but progressive in its course, characterized by the development of an irregular, dense and hard, flattened, tubercular, non-ulcerating, cellular new growth, having its seat about the nose and contiguous parts. The overlying skin is normal in color, or it may be light- or dark-brown or reddish. Marked disfigurement and closure, partial or complete, of the nasal orifices gradually results. It is met with chiefly in Austria and Germany. Treatment, consisting of partial or complete extirpation, is rarely permanent in its results, the disease tending to recur. #Lupus Erythematosus.# (_Synonyms:_ Lupus Erythematodes; Lupus Sebaceus; Seborrh[oe]a Congestiva.) #What is lupus erythematosus?# Lupus erythematosus may be roughly defined as a mildly to moderately inflammatory superficial new-growth formation, characterized by one, several, or more circumscribed, variously sized and shaped, pinkish or dark red patches, covered slightly, and more or less irregularly, with adherent grayish or yellowish scales. #Upon what parts is lupus erythematosus observed?#
