A 48-year-old white woman with acute lymphoblastic leukemia was referred to the stomatology outpatient clinic, complaining of lesions in right upper gingiva with a recent episode of febrile neutropenia after a consolidation chemotherapy. At the extraoral examination no alterations were observed. On intraoral examination, small ulcers were observed in attached gingiva, and on right side of the hard palate a nodular and sessile lesion of approximately 2 cm was identified. Lesions on gingiva were as secondary herpes simplex identified by cytology and polymerase chain reaction. Incisional biopsy of nodule confirmed the diagnosis of pleomorphic adenoma.
