Alternaria species are common plant pathogens, but a rare cause of human infection. Previously reported cases of cutaneous alternariosis (Alternaria alternata) in both healthy and immunosuppressed hosts have been characterized by a chronic localized ulcerative eruption in exposed sites. Dermal granulomatous infiltration and variable epidermal changes, with hyphae in both the dermis and epidermis, are characteristic. We present a case with certain unique features. This is the first reported human infection with Alternaria dianthicola. In addition, our patient showed the unusual presentation of clinically noninflammatory subcutaneous nodules of the chest wall. The subcutaneous location of the granulomatous process may have been attributable to deep traumatic inoculation. The circumscribed nodular quality of the infection allowed a surgical therapeutic approach.
