Alternaria spp. infections are rare, but organ transplant recipients and immunosuppressed patients are particularly at risk of developing cutaneous alternariosis. Although cutaneous alternariosis is well-defined, instances of disseminated infection are exceedingly rare. We report a case of disseminated Alternaria infection in an immunocompromised patient from a primary focus of ungual phaeohyphomycosis.

Linear IgA bullous dermatosis (LABD) is a sub-epidermal blistering disorder characterized by deposition of IgA along the basement membrane zone (BMZ) as detected by immunofluorescence microscopy. The diagnosis is made by clinicopathologic correlation with immunofluorescence confirmation. Differentiation from other bullous dermatoses is important because therapeutic measures differ. Prompt initiation of the appropriate therapies can have a major impact on outcomes. We present three cases with prominent palmar involvement to alert the clinician of this potential physical exam finding and to consider LABD in the right context.
