A new form of abdominal zygomycosis different from mucormycosis: report of two cases and review of the literature

Abstract

Two cases of abdominal zygomycosis occurring in apparently healthy individuals are presented. They had chronic evolution and histologic aspects similar to those found in subcutaneous zygomycosis. In both cases there was involvement of stomach and transverse colon. In one case the liver, biliary system, pancreas, and duodenum were also involved. Fungal cultures were negative. These cases apparently represent a new form of zygomycosis because, although visceral in localization, the disease presents an evolution and histologic features different from the classical form of visceral zygomycosis. Since this infection can be treated the importance of early diagnosis is stressed.
