What is cavernous lymphangioma?
Cavernous lymphangioma also known as cystic lymphangioma, cystic hygroma, or lymphangioma cavernosum is a benign tumor characterized by large dilated lymphatic channels with an attenuated en- dothelial lining which could be in some case surrounded by an irregular discontinuous smooth muscle layer (1).
How is lymphangioma diagnosed?
The diagnosis of lymphangiomas can be made before birth if an ultrasound exam picks up on the abnormality. If a doctor notices one after birth, they may order an MRI scan, CT scan, or ultrasound to confirm the diagnosis, and evaluate the size and impact.
What is lymphangioma caused by?
Cause. A lymphatic malformation (lymphangioma) is thought to occur due to abnormal development of the lymphatic system ; however, the exact underlying cause is unknown in most cases. Cystic hygroma (cystic lymphangioma) may occur as part of a genetic syndrome such as Noonan syndrome, Turner syndrome and Down syndrome.
What form of lymphangioma is most common?
Lymphangioma circumscriptum, the common form of cutaneous lymphangioma, is characterized by persistent, multiple clusters of translucent vesicles that usually contain clear lymph fluid (often compared with frog spawn).
What is the composition of cavernous lymphangioma?
Cavernous lymphangioma presents as a large, diffuse, poorly defined, fluctuant soft tissue mass with cystic dilation of the lymphatics in the dermis, subcutaneous tissue, and intermuscular septa. * Skin changes such as hyperplasia, vesicle formation, and hyperpigmentation may also be seen.
Is lymphangioma a benign tumor?
Lymphangiomas are uncommon, benign malformations of the lymphatic system that can occur anywhere on the skin and mucous membranes. Lymphangiomas can be categorized as deep or superficial based on the depth and size of the abnormal lymphatic vessels or as congenital or acquired.
What is the treatment for lymphangioma?
The preferred treatment for lymphangiomas is complete surgical excision. On the basis of the Whimster hypothesis, the large subcutaneous cisterns should be removed to prevent the lesion from resurfacing. Local recurrences are common in lymphangiomas.
Is lymphangioma malignant or benign?
Which of the following describes a lymphangioma?
A lymphangioma is a swelling or mass that occurs mainly in the head, neck, and mouth. Lymphangiomas are the result of a congenital condition and are usually apparent at birth, or at least by the time a person is 2 years old.
How do you treat lymphangioma?
Is lymphangioma a neoplasm?
Lymphangiomas are benign neoplasms that are regarded as malformations arising from sequestrations of lymphatic tissue that fail to communicate with the normal lymphatic system during embryogenesis (Weiss et al, 2008).
Can lymphangioma go away on its own?
Most lymphatic malformations that appear suddenly will decrease in size and pain without treatment, but very rarely go away on their own. Incision (cutting into) and draining the lymph from a lymphatic malformation can temporarily reduce its size. This is usually only done for diagnosis or to treat an infection.
Cavernous lymphangioma is a rare lesion in the breast of adults. Only a few cases have been documented in literature. Case presentation We describe a 38-year-old woman who presented with a palpable breast lump, which measured 5 × 4 cm.
What is the size of mediastinal cavernous lymphangioma?
It was 4.2 x 3.4 x 3.2 cm in size and the cut surface of the tumor had an appearance consisting of the soft solid tissue, but containing partial cystic spaces. Histological diagnosis was cavernous lymphangioma. The mediastinal cavernous lymphangioma has been reported in only 6 cases in the Japanese medical literature.
How common is lymphangioma in the breast?
Lymphangioma in the breast is a rare entity, and only a few cases have been documented in the literature [1-9]. Lymphangiomas are composed of dilated lymphatic channels lined by endothelium. They occur predominantly in children, with up to 90% of cases presenting by the second year of life [10,11].
Is lymphangioma benign or aggressive?
Discussion Lymphangiomas are relatively uncommon lesions, more so in the breast, where they are very rare. Some authorities regard lymphangiomas to be true neoplasms that are capable of local aggressive behaviour, but overall they are benign [11].
