Abstract

Sixty-six cases of erythena nodosum(EN) and erythema induraturn(EI) were examined pathologically and clinically. Pathologically 23 cases were erythema nodosum, 43 cases were erytherna induratum. Pathological diagnosis made without any prior knowledge of the clinical and laboratory data. Clinical manifestations were reviewed on basis of pathological diagnosis. The results are as follows; l. EN and EI mainly occurred in female, age of twenties and during spring season. There was no difference in sex, age and seasonal incidence between EN and EI. 2. Both EN and EI affected chiefly the shins. EI was more common than EN in cases of calf involvement. 3. Tenderness and systemic symptoms developed more often in EN, while ulcers occurred only in EI. 4 EI had relatively long duration. There was no difference in the recurrence rate between EN and EI. 5. Pulmonary tuberculosis was found only in El on chest X-rays. 6. Clinical and pathological diagnosis was identical in almost cases of EN but those were variable in case of EI.
