Disseminated herpes simplex virus type 1 infection manifested as extensive oral ulcers, pneumonitis, and ileo-colitis in a neutropenic patient post-chemotherapy for osteosarcoma

Abstract

Herpes simplex virus (HSV) is a common cause of recurrent oropharyngeal ulcers or stomatitis resulting from the reactivation of latent infection since childhood. Extensive ulceration and dissemination to vital organs such as pneumonitis or colitis is mostly encountered among hematologic malignancy or hematologic stem cell transplants. We hereby reported a case with osteosarcoma who developed disseminated HSV infection during neutropenia after chemotherapy.
