[Guest guest]

Subacute Nodular Migratory Panniculitis (Vilanova Disease)AKA: chronic erythema nodosum, erythema nodosum migrans Physical: The

examination typically reveals a unilateral, single, discrete,

erythematous nodule or plaque on the anterolateral part of a lower

extremity.The lesion displays peripheral extension, and the central portion may have a yellowish hue later in the course.A characteristic lack of ulceration of these lesions is noted.Over weeks or months, the nodules migrate (hence the name) and can become crescentic in nature.Causes: Although

this disease has been likened to erythema nodosum, the typical

causative agents for classic erythema nodosum are not applicable to

Vilanova disease. No obvious cause is apparent, but some reports

document streptococcal infection in some patients.
