livedo reticularis/necrosis

Cutaneous polyarteritis nodosa (CPN) is a well-known entity showing subcutaneous tender nodules, livedo reticularis, and ulcerations as predominant features; arthralgia, myalgia, peripheral neuropathy, and general symptoms such as fever and malaise may also be present. Although the localization of

Three weeks after electrocoagulation of an enormous epithelioma of the floor of the mouth, a 62-year-old man presented after a shower-bath with symmetrical cyanosis of the toes and fingers with painful oedema coloured by livedo reticularis of the lower third of the legs and forearms. In the hands

Cholesterol crystal embolism is a multisystem disorder with a high mortality. It is usually seen following vascular surgery and long term anticoagulation therapy, but the diagnosis is often not considered. Skin manifestations are the first sign of cholesterol crystal embolism and recognition of the

During the Coronavirus 2019 (COVID-19) pandemic, several associated skin conditions were reported in infected patients, including; urticaria [1], exanthema [1], erythema multiforme [2], chickenpox-like vesicles [1], pityriasis rosea [3], herpes simplex reactivation [4], erythema nodosum like Sweet's

BACKGROUND Heparin-associated thrombocytopenia and thrombosis (HATT) is an infrequently encountered syndrome characterized by ischemic necrosis of soft tissue and vital organs following anticoagulation with heparin. The syndrome is thought to be due to heparin-dependent platelet aggregation and

BACKGROUND Cutaneous necrosis of the proximal lower extremities in a patient with end-stage renal disease is the classic presentation of calciphylaxis, an untreatable, rare, generally fatal necrotizing cutaneous syndrome. Type 1 primary hyperoxaluria (PH-1) usually presents in childhood with

The term livedo reticularis refers to a reddish-violet reticular discoloration of the skin that mainly affects the limbs. It is caused by an interruption of blood flow in the dermal arteries, either due to spasm, inflammation, or vascular obstruction, and is associated with diseases of varying

Three patients with advanced atherosclerotic vascular disease developed multiple cholesterol emboli. The clinical presentation typically includes livedo reticularis of the lower part of the body and purple toes. Small areas of necrosis and ulceration may be present distally, despite palpable pulses.

We report a patient with Buerger's disease (BD) who showed painful nodular erythema with livedo reticularis as an initial symptom. The patient developed this cutaneous manifestation in both lower extremities, and a skin biopsy demonstrated perivascular infiltration of mononuclear cells in the border

Scrotal necrosis is an extremely rare complication following endovascular abdominal aortic aneurysm repair. Sloughing of scrotal skin and penile necrosis owing to therapeutic hypogastric artery occlusion for endoluminal aortoiliac aneurysm repair have been documented. We present herein one case of

A patient with longstanding pseudohypoparathyroidism undergoing substitution with dihydrotachysterin, with normal to low serum calcium and phosphorus levels, developed extensive calcification of the subcutaneous tissue and an obliterative and calcified arteriopathy of the small subcutaneous arteries

Cutaneous necrosis with microvascular calcification is a rare and serious complication of chronic renal failure and has been given the sobriquet of 'calciphylaxis'. We describe four dialysis-dependent patients with proximal cutaneous necrosis who presented with this distinctive clinical syndrome.

A 50-year-old Japanese female with chronic renal failure who had been on continuous ambulatory peritoneal dialysis developed fulminant systemic cutaneous necrosis that began as painful livedo reticularis-like skin lesions on her thighs. Because of disseminated vascular calcification within the
