Primary cutaneous mucormycosis in a healthy young girl. Report of a case caused by Mucor hiemalis Wehmer.

We report an unusual case of primary cutaneous mucormycosis caused by Mucor hiemalis Wehmer that occurred in a healthy young girl after an insect bite. The patient had a slowly extending, indurated, erythematous, and scaling eruption on the right cheek. Histologic examination revealed granulomatous dermatitis and characteristic broad, nonseptate, pale-staining hyphae. This is the first report of an infection in a human being caused by Mucor hiemalis Wehmer. The infection was cured with intravenous amphotericin B.

Patch tests with some spices.

Experience is necessary to use commercially available spices and seasonings for patch testing. This experience is easily obtained by composing your own series of locally important flavorings and by using this series to assess the irritant potency. In our patients, not many strong irritation reactions were elicited. Only 100 per cent garlic powder was obviously too irritant, whereas 25 per cent in petrolatum might be too low to detect allergy. Positive reactions to unknown spices need to be checked in controls; this is important when patch tests are done with spices brought in by the patient. A positive patch-test reaction to a fragrance or perfume indicator in housewives, cooks, and confectioners with hand eczema is an indication to perform patch tests with spices because of the relation between spices and fragrances.
