Is erythema nodosum the same as panniculitis?

Erythema nodosum is a type of panniculitis. Panniculitis occurs when there is inflammation of the layer of fat lying underneath the skin. The inflammation causes red rounded lumps (nodules) to form just below the skin surface, which are tender. Erythema nodosum most commonly affects both shins.

What is the pathophysiology of erythema nodosum?

Erythema nodosum is a septal panniculitis with small foci of inflammatory cells extending into the adjacent lobular fat (Fig. 17.1). In some cases this spillover of cells is more marked and includes foam cells, sometimes associated with focal necrosis of fat cells adjacent to the septa.

Does cytomegalovirus cause septal panniculitis?

SEPTAL PANNICULITIS. The septal panniculitis reported in a patient with cytomegalovirus infection was probably an infective panniculitis and not erythema nodosum.11 It has also been recorded in a patient with cryoglobulinemia (see p. 200) and in patients receiving apomorphine infusion for Parkinson’s disease.

What is the pathophysiology of septal panniculitis?

In septal panniculitis the inflammatory reaction is centered on the connective tissue septa of the subcutaneous fat.7 If the lesions are of long standing or recurrent in the same area, the septa may be considerably widened with a corresponding reduction in the amount of intervening lobular fat.
