title: Pityriasis rosea. Viral complement fixation studies.
abstract: Eleven patients were seen for pityriasis rosea and underwent acute and convalescent viral complement fixation tests for several respiratory viruses and Mycoplasma. Several patients (6/11) gave a history of antecedent upper respiratory illness; however, no significant rise in titer was seen on any of the complement fixation tests.
