Erythema nodosum is an acute, nodular, erythematous eruption usually limited to the extensor aspects of the lower legs. It could be idiopathic or associated with other systemic diseases. We, herein, report a phenotypically healthy, ten-year-old boy who presented with erythema nodosum in whom serological tests of autoimmunity and intestinal histological examination were compatible with celiac di...

Five patients presenting with erythema nodosum to an accident and emergency department are described. Initially they were misdiagnosed as cellulitis, infected insect bites, and minor trauma. Suspicious skin lesions or joint manifestations occurring either alone or especially if in combination should alert the wary clinician to the possibility of erythema nodosum and follow up in a few days may ...

Two children developed erythema nodosum due to Pasteurella pseudotuberculosis. Neither case showed typical signs of P. pseudotuberculosis infection, but this cause was shown by positive agglutination tests. It is suggested that this organism is a more common cause of erythema nodosum than is at present recognized.

Erythema nodosum and pyoderma gangrenosum are common skin manifestations in inflammatory bowel diseases. Curiously, these two cutaneous features have seldom been reported to occur simultaneously. We present three patients affected with inflammatory bowel disease with concomitant erythema nodosum and pyoderma gangrenosum.

A woman presented with erythema nodosum followed by bilateral breast abscesses without a gastrointestinal manifestation, due to a rare serotype of Salmonella, namely, Salmonella enterica serotype Poona. This is the first reported case of erythema nodosum presumably associated with Salmonella infection without a gastrointestinal manifestation.

Myelodysplastic syndrome (MDS) is a heterogenous group of stem cell disorders usually characterized by progressive refractory cytopenias, which could progress to acute myeloid leukemia. MDS may be associated with a wide spectrum of skin lesions, including neoplastic cell infiltration, Sweet's syndrome, pyoderma gangrenosum, erythema elevatum diutinum, vasculitis, and panniculitis. However, eryt...
