Erythema Nodosum Migrans.

We present a case of erythema nodosum migrans (Chronic E.N). It differs from the acute form of erythema nodosum in several aspects. Instead of multiple bilateral small nodules one or more large unilateral nodule appear, which then undergo gradual clearing while peripheral `migratory` satellite nodules appear. Scaring, ulceration, and tenderness are absent. The eruption can last for years rather than months. Accompanying systemic signs or symptoms are less frequent than with acute forms, but despite this apparent difference considerable overlap with acute forms can occur.

CASE REPORT: A fifty year old lady was referred from cardiology clinic. She had ischemic heart disease and painful erythematous nodules on shins since two years. She was taking Tenormin Lasoride, and Ascard for IHD. Apart from tender nodules on the shins, general and physical examination was unremarkable. All biochemical and hematological investigations (including ASO titre and ACE) were normal. X-Ray chest showed no abnormality.
