Lymphangiomatosis can occur at any age, but the incidence is highest in children and teenagers. Signs and symptoms are typically present before the age of 20 and the condition is often under-recognized in adults. [2] It affects males and females of all races and exhibits no inheritance pattern.
Given the phenotypic variability, there are no established diagnostic criteria. Instead, the diagnosis is made based on clinical evidence and supporting histopathology that demonstrates the presence of positive lymphatic markers, such as podoplanin (D2-40) or lymphatic vessel endothelial hyaluronan receptor 1 (), as well as negative glucose transporter 1 ().
The prognosis for lymphangioma circumscriptum and cavernous lymphangioma is generally excellent. This condition is associated with minor bleeding, recurrent cellulitis , and lymph fluid leakage. Two cases of lymphangiosarcoma arising from lymphangioma circumscriptum have been reported; however, in both of the patients, the preexisting lesion ...
Treatment is often pursued for troubling symptoms (itching, pain) or for cosmetic reasons. Surgical removal (excision) of the affected skin layers is the most common and effective treatment. Ablative carbon dioxide laser therapy is a less invasive method that can improve the appearance.
Radiologists must be aware of these conditions in order to avoid misdiagnosing patients. Examples of such lesions are: pleural plaques, thoracic splenosis, catamenial pneumothorax, pleural pseudotumor, diffuse pleural thickening, diffuse pulmonary lymphangiomatosis and Erdheim–Chester disease. [1]
Whether the benefits of treatment outweigh the risks for asymptomatic LAM patients with normal lung function is not clear, but some physicians consider treatment for declining patients who are approaching the abnormal range for FEV1. Sirolimus also appears to be effective for the treatment chylous effusions and lymphangioleiomyomatosis.
Lymphohemangioma is a disease characterized by swelling of the lymph nodes and blood vessels.It is variously described as a "mixture of clear fluid and blood-filled cysts", [citation needed] a mass of abnormal swollen veins and lymph nodes, or a tumorous growth of lymph and blood vessels.
Lymphatic malformations may be discovered postnatally or in older children/adults, and most commonly present as a mass or as an incidental finding during medical imaging. Verification of the diagnosis may require more testing, as multiple cystic masses can arise in children. [9]
