Lymphangioma — the benign tumor coming from absorbent vessels.


The majority of tumors exists since the birth or appear soon after it.


Distinguish 3 types of lymphangiomas:
• capillary (simple);
• cystous;
• cavernous.
Besides, distinguish primary and secondary lymphangiomas.

Etiology and pathogeny

 Primary lymphangiomas — a malformation.

Secondary lymphangiomas are a consequence of disturbances of a lymphokinesis (after the postponed infectious diseases).

Clinical signs and symptoms of lymphangiomas

Tumors are located on any site of skin and mucous membranes, is more often on a neck, in an oral cavity, on upper extremities.
Capillary lymphangiomas are characterized by existence of small bubbles, is more often multiple, filled with transparent liquid, a yellowish shade, located is grouped. Lymphangiomas can have purple color because of blood impurity. The lymphangiomas resulting from a lymphostasis represent well delimited erythematic plaques or spots which are gradually increasing in sizes.

The diagnosis and the recommended clinical trials

The diagnosis is made on the basis of clinical manifestations and results of histologic research.

In upper part of a derma the cystous and expanded absorbent vessels covered by one layer of endotheliocytes are located. Sometimes except a lymph they contain a few erythrocytes. Epidermis thickness unequal, over cysts it usually becomes thinner. In other sites there can be an acanthosis and a papillomatosis with unevenly expressed epidermal outgrowths. Some sharply expanded vessels are as if included in epidermis. Expansion of absorbent vessels can be observed up to a middle part of a derma, but not below. At a cystous lymphangioma the hyperkeratosis and a papillomatosis are expressed stronger, increase in a gleam of absorbent vessels is observed in hypodermic cellulose where it is often possible to see expanded absorbent vessels of large caliber with hypertrophied muscular walls. At a cavernous form in deep departments of a derma and in hypodermic fatty tissue are formed wide, irregular shape of a crack, often containing erythrocytes. In lips and language lymphatic cracks are located between muscle bundles, moving apart them therefore fabric has a spongy appearance.

Differential diagnosis

Lymphangiosarcoma, Kaposha's sarcoma.

General principles of treatment

Electrocoagulation of solitary elements. At the limfangita accompanying a lymphostasis an antibioticotherapia is shown.

Favorable at solitary forms.
