1/47. lymphangioma circumscriptum of the tongue.A case is reported of severe transient macroglossia after biopsy from the tongue in a 13-year-old boy who has had intermittent macroglossia since the age of 1 year as a result of extensive lymphangioma circumscriptum of the tongue. The acute lesions appear to result from haemorrhage into the lymphatic spaces following rupture of blood vessels in connective tissue septa and possibly secondary infection.- - - - - - - - - - ranking = 1keywords = blood vessel, vessel (Clic here for more details about this article) |
2/47. klippel-trenaunay-weber syndrome presenting as massive lymphangiohemangioma of the thigh: prenatal diagnosis.We report a case of klippel-trenaunay-weber syndrome presenting prenatally as a massive congenital lymphangiohemangioma of the thigh. Routine ultrasonographic examination revealed multiple distorted cystic areas extending from the right flank through the right lower extremity of a 30-week fetus. A diagnosis of cystic lymphangioma of the thigh was suspected prenatally. Neonatal evaluation confirmed the prenatal findings. Neonatal color Doppler imaging revealed blood vessels within the tumor. The differential diagnosis is discussed together with available therapeutic procedures.- - - - - - - - - - ranking = 1keywords = blood vessel, vessel (Clic here for more details about this article) |
3/47. lymphangioma circumscriptum of the vulva.lymphangioma circumscriptum is a benign disease of the lymph ducts and an unusual pathologic process that rarely affects the vulva. The etiology of this lesion is not clear, but obstruction of the lymph vessels has been suggested as a possible cause in some cases. We report the case of a 44-year-old woman with lesions similar to lymphangioma circumscriptum of the vulva and chronic idiopathic lymphedema of the lower right limb. Because there was no obvious cause, we propose that the lymphangioma was caused by the lymphedema.- - - - - - - - - - ranking = 0.16724193969736keywords = vessel (Clic here for more details about this article) |
4/47. Orbital lymphangioma with positive immunohistochemistry of lymphatic endothelial markers (vascular endothelial growth factor receptor 3 and podoplanin).BACKGROUND: Existence of true orbital lymphangiomas has been questioned in recent years. Therefore an orbital lymphangioma was analyzed with two new specific markers of lymphatic endothelium. methods: Case-report with clinicopathological, immunohistochemical, and ultrastructural findings. A 25-year-old man presented with recurrent lower lid "hematomas" and a pea-sized tumor palpable in the left lower lid. magnetic resonance imaging showed an inferonasally located orbital tumor which extended to the posterior pole of the eye. The highly vascularized tumor was excised by medial orbitotomy. RESULTS: Histopathologically, the mass consisted of large, erythrocyte-filled cavernous vessels without evidence of smooth muscle cells or pericytes surrounding them. Numerous lymph follicles and small arterioles were scattered between them. Immunohistochemically, endothelial cells lining the lumina of the cavernous vessels were partly positive for podoplanin and vascular endothelial growth factor receptor 3 (flt-4), two markers of lymphatic endothelium. These markers did not react with endothelial cells lining the arterioles. Ultrastructurally, cavernous vessels displayed features characteristic of lymphatic vessels, and the smaller vessels demonstrated signs of arterioles. CONCLUSION: Ultrastructural analysis and immunohistochemistry using two new markers of lymphatic endothelium suggest a lymphatic nature of large vessels in an orbital lymphangioma. A greater series of vascular orbital tumors must be studied with these new lymph endothelial markers to confirm the existence of true orbital lymphangiomas and to analyze different profiles of lymph endothelial marker expression.- - - - - - - - - - ranking = 1.0034516381842keywords = vessel (Clic here for more details about this article) |
5/47. Massive osteolysis of skull bones secondary to lymphangioma of paranasal sinuses and mastoid sinus: report of two cases in children.Massive osteolysis (MO) is a rare condition in which progressive localized bone tissue resorption is associated with proliferating thin-walled vessels in the absence of inflammation. Rare cases have been reported to occur in the skull. This paper describes two patients with MO who presented with massive assymetric swelling of the skull. This was associated with extensive enlargement of the paranasal sinuses (frontal, ethmoidal, and sphenoidal in one and the mastoid air cells in the other). The second patient developed subcutaneous emphysema on several occasions and the valsalva maneuver increased the swelling, indicating transmission of the air from the nasopharynx to the mastoid cells and from there to the subcutaneous tissue. In the first patient, the sinus mucosa was shown to be involved by an extensive lymphangioma, and a similar change was seen in the mastoid air cells (patient 2). We are proposing that MO of these two patients resulted from bone resorption due to progressive extension of sinus mucous lymphangiomata.- - - - - - - - - - ranking = 0.16724193969736keywords = vessel (Clic here for more details about this article) |
6/47. Solitary lymphangioma of the femur. A case report.lymphangioma of the bone is a benign lesion, characterized by newly formed lymph vessels. It usually occurs in a diffuse manner or as multiple lesions. Solitary lymphangioma of the bone is an extremely rare condition. We herein describe a case of solitary lymphangioma of the femur in a 55-year-old woman who presented with knee pain. Radiographs showed an eccentric osteolytic lesion in the distal femur. This is the first reported case of solitary lymphangioma of the bone occurring in the femur.- - - - - - - - - - ranking = 0.16724193969736keywords = vessel (Clic here for more details about this article) |
7/47. Free lateral supramalleolar flap transfer as a small, thin flap.Lateral supramalleolar flaps were elevated as free flaps and transferred with microvascular anastomoses in 3 patients. The peroneal vessels were used for the vascular anastomosis. In all patients, the flaps survived completely. The free lateral supramalleolar flap is thinner than the peroneal flap and is as thin as the radial forearm flap. This flap is useful when thin, small flaps are required, and may be a valuable alternative to the radial forearm flap because it necessitates less donor site morbidity.- - - - - - - - - - ranking = 0.16724193969736keywords = vessel (Clic here for more details about this article) |
8/47. lymphangioma circumscriptum of the vulva following surgical and radiological therapy of cervical cancer.BACKGROUND: lymphangioma circumscriptum of the vulva rarely develops after postoperative pelvic irradiation. GOAL: The goal was to describe two cases of lymphangioma circumscriptum and their treatment and present a brief review of the literature. STUDY: Two female patients, aged 75 years and 46 years, presented with persistent edema, papules, and vesicles of the labia majora, which had developed 15 and 9 years after hysterectomy, lymph node dissection, and subsequent irradiation of cervical cancer. The external diagnosis was genital warts. RESULTS: In both cases histology revealed lymphangioma circumscriptum of the vulva. Whereas the older woman's condition responded well to laser treatment, keloids developed in the second patient at the site of carbon dioxide laser vaporization. CONCLUSION: CO2 laser treatment recently has been recommended for vulvar lymphangioma circumscriptum and is effective in vaporizing the communicating vessels to deeper cisterns. To our knowledge this is the first description of keloid development after laser therapy for vulvar lymphangioma circumscriptum, and such an effect should be considered before CO2 laser surgery is applied for this particular entity.- - - - - - - - - - ranking = 0.16724193969736keywords = vessel (Clic here for more details about this article) |
9/47. Multiple lymphangioendothelioma of the spleen in a 13-year-old girl.A 13-year-old girl had a history of an upper-quadrant abdominal mass for about six months. On exploratory laparotomy, multiple discrete large nodules were seen in the spleen. Histologically, the spleen had the unusual appearance of lymphangioma, in that there was a tremendous proliferatiion of endothelial cells that formed either papillary projections in the lumina of the cavernous lymphatic vessels or a solid mass of cells without the lumina. The changes were suggestive of sarcomatous transformation, but the evidence was not conclusive. A term "lymphangioendothelioma" is proposed for this multinodular tumor.- - - - - - - - - - ranking = 0.16724193969736keywords = vessel (Clic here for more details about this article) |
