A case of sarcoidosis which relapsed twice after successive parturitions.

A 30-year-old Japanese woman relapsed into sarcoidosis after two successive parturitions. The cutaneous lesions consisted of scar sarcoidosis, papular type, nodular type, and subcutaneous nodules with histologically typical "naked tubercles". Hypergammaglobulinemia, elevation of both serum angiotensin converting enzyme and lysozyme levels, and bilateral hilar lymphadenopathy were found in the acute and subacute stages, and spontaneously returned to normal levels 16 months after the onset. Our case suggests that parturition may trigger the onset of sarcoidosis.
