Differences in anti-phosphatidylserine-prothrombin complex antibodies and cutaneous vasculitis between regular livedo reticularis and livedo racemosa.

OBJECTIVES We examined the prevalence of LAC, aCL antibodies (Abs), anti-beta(2)-glycoprotein I (anti-beta(2)GPI) Abs and anti-phosphatidylserine-prothrombin complex (anti-PS/PT) Abs in patients with regular livedo reticularis or with livedo racemosa to determine whether those Abs correlate with the clinical or serological features. Assuming that a correlation exists, early recognition of the s...

Sneddon's syndrome (livedo racemosa and cerebral infarction) presenting psychiatric disturbance and shortening of fingers and toes.

A 24-year-old man with livedo racemosa and psychiatric disturbances, manifesting as low intelligence (IQ 80) and delusions, had anti-cardiolipin antibody and showed shortening of the fingers and toes. A skin biopsy of the livedo lesion revealed endoarteritis obliterans, being compatible with Sneddon's syndrome. MRI of the brain demonstrated multiple infarction and moderate cortical atrophy. A s...

Livedo Racemosa, Reticulated Ulcerations, Panniculitis and Violaceous Plaques in a 46-year-old Woman

Clinically amyopathic dermatomyositis (CADM) is a subset of dermatomyositis (DM) that has conventional cutaneous manifestations of DM, but paradoxically, little or no muscle involvement. In 2005, a novel antibody was described in association with CADM - anti-melanoma differentiation-associated gene 5 (anti-MDA5). Patients with this serologic marker have a characteristic mucocutaneous phenotype ...
