Invasive oral aspergillosis in immunocompromised patients with leukemia.
The clinicopathologic characteristics of invasive oral aspergillosis in 16 immunocompromised patients who developed this infection during antileukemic chemotherapy are described. The primary site of the infection was the marginal gingiva, there was severe spontaneous pain, and the patients developed spiking fever and granulocytopenia. Necrotic ulceration of the gingiva rapidly extended to the contiguous mucosa, muscle, and bone. Microscopically, the necrotic tissue contained thrombotic vascular infarcts and there were hyphae that showed frequent transverse septa and dichotomous branching. The invasive organisms were not responsive to amphotericin B in the absence of remission of the leukemia and restoration of the depressed host defenses. In 15 patients who showed improvement of hematologic status, oral aspergillosis was controlled by the combination of antifungal chemotherapy and debridement of necrotic tissues.
