An autopsy case of periarteritis nodosa associated with disseminated strongyloidiasis in a 59-year-old woman is reported. The patient had unknown fever of 38 degrees C and marked impairment of renal function, for which pulse therapy of steroid was performed. Electromyogram showed myogenic pattern, and biopsy of the biceps presented necrotizing angitis of small arteries. Renal biopsy showed marked infiltration of lymphocytes in the stroma, and frequent hyalinosis and crescent formation of the glomeruli. Two months after admission, the patient died of respiratory failure associated with sepsis and disseminated intravascular coagulopathy. Postmortem examination disclosed strongyloides stercolaris and fungi in both lungs with extensive hemorrhage. Terminal ileum and ascending colon had multiple erosions, extensive hemorrhage, numerous strongyloides stercolaris, and frequent necrotizing angitis in the mucosa. Necrotizing angitis was also demonstrated in both kidneys.
