Surgical Treatment for Benign Lymphangioendothelioma After Two Incomplete Excisions: A Case Report and Literature Review

Benign lymphangioendothelioma (BL) is a rare, poorly identified, slow-growing benign vascular lesion characterized by asymptomatic, solitary, well-demarcated macules, or by mildly infiltrated plaque. We report a case of an atypical BL that arose as a tender, protuberant, flesh-colored mass with cyanotic vesicles, and then progressed to a persistent exudative wound after two incomplete excisions. The patient was also diagnosed with thoracic duct narrowing. Although the stenosis was removed by surgery, the right lower extremity ulceration and exudation did not improve. Thus, we performed a thorough excision and split-thickness skin graft transplant following vacuum sealing drainage, and eventually the patient had a favorable functional and cosmetic outcome. A biopsy revealed irregular, dilated vascular spaces lined with a single layer of flat endothelial cells extending from the superficial dermis to the subcutis that did not reach the striated muscles. Additionally, by reviewing the literature on BL, in this paper we summarize the diverse pathogenic, morphological, and immunohistochemical presentations for this rare disease, as well as the histopathological differential diagnosis of lymphangiomatosis, Kaposi's sarcoma, and angiosarcoma.

A case of extensive acquired progressive lymphangioma

Acquired progressive lymphangioma (benign lymphangioendothelioma) is a rare lymphatic anomaly of unclear pathogenesis. Excision is generally advised for local disease, although other therapies have been tried. This report describes a unique case of extensive acquired progressive lymphangioma involving the abdomen, genitalia, and lower extremity of a 1-year-old boy. Rapid progression and multisite involvement required exploration of nonsurgical options for management.

BENIGN LYMPHANGIOENDOTHELIOMA

The authors describe modern data relating to the definition, clinical, pathological and immunohistochemical features of a rare vascular tumor — benign lymphangioendothelioma. The problems of differential diagnosis with Kaposi’s sarcoma and angiosarcoma are discussed. This is the first description of this tumorin domestic literature.

Acquired progressive lymphangioma: Case report with partial response to imiquimod 5% cream

Acquired progressive lymphangioma (APL), or benign lymphangioendothelioma, is an unusual entity derived from vascular structures. Clinically and histopathologically it may resemble Kaposi's sarcoma and well-differentiated angiosarcoma, causing a diagnostic problem. We report an individual with APL initially diagnosed with Kaposi's sarcoma who underwent unnecessary laboratory testing. Imiquimod 5% cream stopped the progression of the lesion. Awareness of this rare entity may prevent patients from undergoing excessive testing. Imiquimod may be used as a safe, effective treatment option.
