Saksenaeae Subcutaneous Abscess in an Immunocompetent Child.

Molds, in the order Mucorales, are found worldwide in soil and decaying vegetation. They lead typically to disseminated infection in immunocompromised patients. In contrast, members of the family Saksenaeaceae can cause skin and soft-tissue infections in healthy individuals.1 We report a rare case of a subcutaneous abscess because of Saksenaea vasiformis in a previously healthy 4-year-old boy without a history of recent injury. He presented initially with calf cellulitis, which despite intravenous flucloxacillin, evolved into a subcutaneous abscess requiring multiple incision and drainage procedures (see Fig., Supplemental Digital Content 1, http://links.lww.com/INF/C291). He remained systemically well with a normal full blood count, C-reactive protein was 11 mg/L and erythrocyte sedimentation rate of 11 mm/h. Operative findings revealed caseous material and histology showed necrotic fat, suppurative inflammation and numerous pauciseptate hyphae with right-angled branching and angioinvasion (see Figs., Supplemental Digital Content 2 and 3, http://links.lww.com/INF/C292 and http://links.lww.com/INF/C293).
