Occupational contact dermatitis to propacetamol. Allergological and chemical investigations in two new cases

Two new cases of nasofacial zygomycosis from the state of Pará, Brazil, are reported. Both cases were treated with ketoconazole and the response to the drug was considered to be good; the patients improved rapidly and the nasal obstruction was the first manifestation to disappear. As five cases have been described in recent years from the state of Pará, this form of zygomycosis can no longer be considered as a rare disease in northern Brazil.
