1/50. Acute infantile hemorrhagic oedema.Acute infantile hemorrhagic oedema (AIHO) was first described in 1913 but, despite frequent reports in the European literature, it is not well recognized in the English language literature. It is considered by many to be a variant of Henoch Schonlein purpura (HSP) because of similarities in cause and histopathology. However, because of the benign nature of this condition and frequent absence of IgA associated with HSP, it may be sensible to consider this as a distinct variety of cutaneous small vessel vasculitis (CSVV). We report this case to highlight the condition and emphasize its benign nature.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
2/50. Retinal opacification after blunt non-perforating concussional injuries to the globe. A clinical and retinal fluorescein angiographic study.Fluorescein angiographic studies are reported on fifteen patients presenting with retinal opacification after blunt mechanical non-perforating injuries involving the eye. In patients who subsequently regained full visual function and in whom complete resolution of the retinal changes occurred, retinal fluorography carried out less than 24 hours after injury revealed no abnormal features. In cases with more prolonged visual disability, retinal fluorescein examinations may, however, reveal damage to the retinal pigment epithelium before this becomes apparent on routine ophthalmoscopy, or the existence of impaired perfusion through the retinal vessels. It is suggested, therefore, that retinal fluorescein angiography has a role in assessing the visual prognosis in patients presenting with traumatic retinal oedema.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
3/50. Conjunctival edema and alopecia of the external third of the eyebrows in a patient with meige syndrome.PURPOSE: To describe a patient with meige syndrome in whom we observed the coexistence of hereditary lymphedema of the lower legs, conjunctival edema and alopecia of the lateral third of the eyebrows. methods: Case report. RESULTS: Histological examination of the conjunctival and skin specimens showed dermal edema and a slight reduction in the number of severely ectatic lymphatics in the reticular dermis. The vessel were identified as lymphatics on the basis of immunohistochemical evidence of discontinuity and/or absence of basement membrane. CONCLUSIONS: Clinical and histological findings suggest that the etiopathogenesis of the edema in meige syndrome is related to a structural ectatic defect of lymphatics. This anomaly seems to involve both skin and other sites, such as conjunctival mucosa.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
4/50. melkersson-rosenthal syndrome: new clinicopathologic findings in 4 cases.OBJECTIVE: To define the clinicopathologic features of eyelid involvement in melkersson-rosenthal syndrome (MRS). methods: Four patients with eyelid edema consistent with MRS were evaluated clinically, including diagnostic imaging in 2 patients. Eyelid tissue from these patients was examined by light microscopy and immunohistochemistry. polymerase chain reaction for herpes simplex virus was performed in 1 case. RESULTS: The 3 men and 1 woman ranged in age from 33 to 74 years. All patients had insidious, painless, nonpitting eyelid edema. Three patients had unilateral edema; one had bilateral, asymmetric involvement. Ipsilateral lip edema was present in 1 case. Computed tomography demonstrated periorbital heterogeneous thickening that corresponded to the microscopic finding of scattered granulomas. All 4 patients demonstrated epithelioid granulomas inside and adjacent to dilated lymphatic vessels. polymerase chain reaction testing was negative for herpes simplex virus. CONCLUSIONS: Isolated eyelid swelling that mimics thyroid-associated ophthalmopathy may occur in MRS. Computed tomography may be useful in the diagnosis. biopsy should be performed in all cases of unexplained nonpitting eyelid edema. In the eyelid, MRS is characterized histopathologically by a granulomatous lymphangitis, a finding that seems to be unique to this condition.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
5/50. superior vena cava syndrome presenting as persistent erythematous oedema of the face.The superior vena cava syndrome occurs when extrinsic compression or intraluminal occlusion impedes blood flow through this vessel. Detecting the characteristic cutaneous features can lead to an early diagnosis of this condition. We report a 73-year-old patient with a 4-year-history of erythematous oedema of the face. The underlying cause was a large retrosternal goitre obstructing the superior vena cava. Subtotal thyroidectomy led to dramatic improvement of all dermatologic symptoms.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
6/50. Traumatic pseudoaneurysm of the thyrocervical trunk.A case of a pseudoaneurysm of the thyrocervical trunk after a pocketknife stab wound to zone I of the neck is reported. The patient was evaluated and treated in an emergency department with irrigation of the wound, bandage, and oral antibiotics. A large pseudoaneurysm slowly developed over the next 2 months. When the patient arrived at our hospital, he was immediately admitted and arteriograms were obtained. Arteriograms revealed an active leak of blood into a pseudoaneurysm from the thyrocervical trunk. Surgical treatment consisted of proximal and distal ligation of the thyrocervical trunk. This is the first case of a pseudoaneurysm developing only from the thyrocervical trunk due to a stab wound to zone I of the neck. This case and its complication serve to illustrate and emphasize the rationale for routinely imaging the great vessels after all penetrating trauma to zone I of the neck.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
7/50. Total occlusion of inferior vena cava in a patient with antiphospholipid antibody syndrome associated with behcet's disease.Behcet's disease frequently involves the venous system, usually affecting small vessels, but sometimes large vessels such as the vena cava. Antiphospholipid antibody syndrome is associated with an increased incidence of arterial and venous thrombosis. A 29-year-old male with Behcet's disease developed bilateral leg edema secondary to thrombotic occlusion of the inferior vena cava. Laboratory tests revealed positive antiphospholipid antibodies and lupus anticoagulant. Treatment with steroid and warfarin subsequent to intravenous administration of uro-kinase resulted in improvement of symptoms. The association of antiphospholipid antibody syndrome and Behcet's disease may have caused the total thrombotic occlusion of the vena cava in this case.- - - - - - - - - - ranking = 2keywords = vessel (Clic here for more details about this article) |
8/50. Swelling of the leg, deep venous thrombosis and the piriformis syndrome.BACKGROUND: The piriformis syndrome, which was first described 60 years ago, is a well recognized cause of sciatica, leg pain and low back pain, due to the entrapment of the sciatic nerve in the piriformis and other rotator muscles. Very few complications relating to this syndrome have been described. AIMS: To discuss how the piriformis syndrome may cause venous engorgement in the lower limb, and how the piriformis syndrome should be included as a possible cause of acute deep venous thrombosis in a not initially swollen leg. Both complications can occur independently. methods: Two cases of swelling of the leg and acute deep venous thrombosis independently associated with the piriformis syndrome are presented. CONCLUSIONS: Swelling of the leg and deep venous thrombosis are possible complications of the piriformis syndrome that occur due to entrapment of nerves and vessels within the leg, secondary to a severe spasm and hypertrophy of the piriformis and other rotator muscles.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
9/50. prenatal diagnosis of Milroy's primary congenital lymphedema.Milroy's primary congenital lymphedema (PCL) (hereditary lymphedema type I, Milroy disease) is present at birth, and mostly affects the dorsal aspects of feet. It is mostly a life-long condition but does not affect longevity. Complications are rare except for chronic discomfort and warmness of affected areas. PCL is an autosomal dominant disease with incomplete penetrance due to a mutation in the gene locus encoding for VEGFR3 with resultant dysgenesis of microlymphatic vessels. We report on two fetuses where ultrasonographic examination at 15 weeks of gestation showed significant edema of the dorsal aspects of both feet with no evidence of other major malformations. Whereas in one fetus the edema resolved completely, it persisted in the second fetus and proved after birth to be of lymphedematous nature. To the best of our knowledge, this is the first report of early prenatal diagnosis of primary congenital lymphedema via fetal ultrasonographic examination and of spontaneous resolution of lymphedema during fetal life.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
10/50. Palpebral edema as a cutaneous manifestation of hyperthyroidism.Three cases of palpebral edema associated with Graves' disease are described. These patients had unilateral edema and minimal erythema of the upper eyelid. Notable was that, histologically, dermal edema and dilation of lymphatic vessels were observed, but deposition of mucopolysaccharides was not. In 2 cases, edema of the eyelid was resistant to treatment with an antithyroid drug. Unilateral edema of the upper eyelid is an important cutaneous manifestation that indicates the presence of hyperthyroidism.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
