lymphangioma

 [lim-fan″je-o´mah]
a benign tumor composed of newly formed lymph spaces and channels. adj., adj lymphangio´matous.
lymphangioma caverno´sum (cavernous lymphangioma)
1. a deeply situated lymphangioma, composed of cavernous lymphatic spaces, and always occurring in the neck or axilla.
lymphangioma circumscrip´tum a cutaneous lymphangioma more superficial than the cavernous type, usually localized upper portion of the limbs, the axillary or inguinal folds, or the oral mucosa, especially the tongue; it consists of a grapelike group of thin-walled translucent lymph-filled vesicles that sometimes have a wartlike surface.
cystic lymphangioma (lymphangioma cys´ticum) cystic hygroma.
simple lymphangioma (lymphangioma sim´plex) one composed of small lymphatic channels that occurs subcutaneously in the head and neck region, in the axilla, and sometimes in internal organs. Superficial lesions are slightly raised or sometimes nodular; deeper lesions are sharply circumscribed, compressible, and gray to pink in color.

lym·phan·gi·o·ma

(lim-fan-jē-ō'mă),
General term for tumors formed by a mass of anomalous lymphatic vessels or channels that vary in size, are usually greatly dilated, and are lined with normal endothelial cells; lymphoid tissue is usually present in the peripheral portions of the lesions, which are present at birth, or shortly thereafter, and probably represent maldevelopment of lymphatic vessels (rather than true neoplasms); they occur most frequently in the neck and axilla, but may also develop in the arm, mesentery, retroperitoneum, and other sites.
[lymphangio- + G. -oma, tumor]

lymphangioma

/lym·phan·gi·o·ma/ (-o´mah) a tumor composed of newly formed lymph spaces and channels.
cavernous lymphangioma 
1. a deeply seated lymphangioma composed of cavernous lymphatic spaces and occurring in the head or neck.
cystic lymphangioma  cystic hygroma.

lymphangioma

[limfan′jē·ō′mə] pl. lymphangiomas, lymphangiomata
Etymology: L, lympha + Gk, angeion, vessel, oma, tumor
a benign yellowish-tan tumor on the skin, composed of a mass of dilated lymph vessels. The tumor is removed by excision or electrocoagulation for cosmetic reasons. Also called angioma lymphaticum. Compare hemangioma.

lymphangioma

A benign, often multi-loculated lesion characterised by a localised proliferation of dilated lymphatics lined by benign endothelial cells.
 
Clinical findings
Lymphangiomas may cause acute abdominal cysts, laryngeal masses, intraabdominal masses.
 
Management
Resection.
 
Prognosis
Excellent.

lym·phan·gi·o·ma

(lim-fan'jē-ō'mă)
A well-circumscribed nodule of lymphatic vessels that are usually greatly dilated and lined with normal endothelial cells; lymphoid tissue is usually present in the peripheral portions of the lesions, which are present at birth or shortly therafter, and probably represent anomalous development of lymphatic vessels (rather than true neoplasms); they occur most frequently in the neck and axilla.

lymphangioma

A benign tumour of lymph vessels, often congenital. Cystic lymphangiomas are called hygromas.

Lymphangioma

A benign skin tumor composed of abnormal lymph vessels.

lymphangioma
