Abstract

Oral fungal infections present with atypical and varied manifestations, and distinguishing them from other entities including leukemic infiltration can be diagnostically challenging. In this report, we describe a 62 year old female with acute myeloid leukemia who presented, towards the end of her second treatment cycle of decitabine in a prolonged neutropenic state, with a month of painful, necrotic-appearing marginal gingival lesions. She was duly initiated on empiric broad spectrum antifungal treatment but did not show a clinical response with the appearance of new skin lesions concerning for progressive fungemia. Concurrent gingival and cutaneous biopsy showed fungal invasion with Fusarium. Despite changing antifungal treatment the lesions progressed, and white blood cell (WBC) transfusions were instituted. The patient had an impressive response with gradual resolution of the skin lesions and regression in gingival lesions over a week of therapy. This case illustrates the highly atypical, confounding appearance of oral fungal infections in immunocompromised hematological malignancy patients. Maxillary and mandibular marginal gingival involvement, although extremely rare, should be recognized as potential sites of fungal involvement. Accurate diagnosis entails a biopsy especially in ambiguous clinical scenarios, as presented here. The role of WBC transfusions in the management of these rare fungal pathogenic infections needs to re-established.
