Livido reticularis

In March of 2020, an otherwise healthy 12-year-old boy developed a unilateral patch of reticulated erythema limited to his left lower extremity. The child could not be examined in the clinic due to limited in-person appointments during the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic, so he was examined via a telemedicine visit. The diagnosis of erythema ab igne was made as his mother verified that the child was spending approximately two hours per day playing video games in the cold basement of his house, with a space heater positioned close to his left leg...

OBJECTIFS: Le syndrome de Sneddon (SS) représente une cause rare d'accidents vasculaires cérébraux (AVC). La prise en charge passe d'abord par la prévention des facteurs de risque et repose surtout sur les traitements antithrombotiques. MéTHODES: Un cas rapporté. RéSULTATS: Patiente de 50 ans, mère de 5EVBP, aux antécédents d'une HTA et de 3 accouchements prématurés, a été admise en service de médecine interne pour pris en charge d'un phénomène de Raynaud sévère compliqué d'une ischémie du gros orteil...

Antiphospholipid syndrome has received considerable attention from the medical community because of its association with a number of serious clinical disorders, including arterial and venous thromboembolism, acute ischemic encephalopathy, recurrent pregnancy loss, thrombocytopenia, and livido reticularis. It can occur within the context of several diseases, mainly autoimmune disorders, and is then called secondary antiphospholipid syndrome. However, it may be also be present without any recognizable disease, or so-called primary antiphospholipid syndrome...

Calcific uremic arteriolopathy (calciphylaxis) is an uncommon complication of chronic renal failure that is associated with high morbidity and mortality. We report 16 patients (13 female) who presented between 1985 and 1996. All patients developed painful livido reticularis that progressed to cutaneous necrosis and ulceration (11 cases on the proximal extremities and five cases on the distal extremities). Two patients with predominately distal leg disease survived; the cause of death in the other 14 patients was sepsis (six patients), withdrawal from dialysis (three), cardiac arrest (three), and gastrointestinal hemorrhage (two)...

OBJECTIVE: To report 10 children younger than 10 years of age with benign cutaneous polyarteritis nodosa (BCPAN). METHODS: Ten children aged 1.25-10 years (mean 4.7 years; M:F = 7:3) were admitted with an unusual vasculitis. The clinical features, laboratory investigations, treatment and follow up data were analysed. RESULTS: Clinical features of these patients included: fever (10), peripheral gangrene (eight), livido reticularis (four), ulceration, nodules and vesiculobullous lesions alone or in combination (10), black necrotic patches over limbs and trunk (three), and arthralgia or swelling of large joints (seven)...

Of four patients with the syndrome of multiple cholesterol emboli (MCES), three had acute renal failure. One patient recovered stable renal function. A radiocontrast study preceded three of the cases. All four patients exhibited the "purple toe" livido reticularis syndrome. Three had a previously unreported findings--necrosis of the scrotum and foreskin of the penis, suggesting that penile and scrotal necrosis may be additional clues to the presence of MCES.

Livedo reticularis and antiphospholipid antibodies have previously been found to be associated with a subgroup of patients with systemic lupus erythematosus. We present a case of livedo reticularis accompanied by antiphospholipid antibodies, in which no other signs of any systemic or cutaneous disease could be detected.

Radiologic procedures that employ intravascular contrast material with or without angiography may lead to renal failure. In procedures that use intravenous contrast alone, the mechanism of renal injury is not precisely known, but direct toxicity to renal tubular cells is likely to be a major factor. Ionic and nonionic contrast agents are both capable of causing this adverse reaction. Renal failure occurring during angiography may also be secondary to the effects of radiocontrast, but the additional possibility that micro cholesterol emboli have been dislodged from atheroma located on the intima of large vessels must be considered...

Pigmented livedo is a frequently encountered disease. It occurs as an ochre reticular membrane which does not disappear when the limb is raised. It is characteristic in persons who already have livido reticularis and who expose themselves for several hours every day to the heat from chimneys or foot-warmers. We wanted to study the histological context of this disease in a group of female patients that we kept under observation. The data that we compiled showed that it is due to lymphocytic vasculitis accompanied by atrophy of the epidermis, hyperpigmentation of the basal keratinocytes and telangiectasia...

A white female with chronic glomerular nephritis received a renal transplant in 1971. After 1 year, Livido Reticularis (LR) developed and in 1976 erythematous, painful nodules formed on the LR and ulcerated. The patient also suffered diffuse calcification of the major blood vessels and small arterioles of the extremities with progressive necrosis and gangrene of the fingers. Hyperparathyroidism was evident. The necrotic ulcers yielded Candida albicans and Fusarium oxysporum; both organisms were seen in histological preparations...

Half of 94 parkinsonian patients improved on amantadine therapy during acute double-blind trials. In a four-year follow-up, amantadine given alone or added to a stable dose of levodopa had its greatest effect in the first month and helped few patients after six months. Levodopa either alone or added to a stable dose of amantadine had a beneficial effect lasting three years or more. The side-effects of edema and livido reticularis occurred twice as often in women. Confusion and hallucinations appeared sooner on a regimen of 300 mg of amantadine a day, but the ultimate incidence was the same on 200 mg a day...
