Granulomatous dermatitis is a common tissue reaction pattern seen in the skin or systematically in various presentations. Granulomatous dermatitis can be subclassified into infectious and non-infectious categories. This article focuses on a patient with non-infectious granulomatous dermatitis followed for many years. Past medical history included bilateral total shoulder arthroplasty complicated by prosthetic joint infections. In its early stages, the axillary rash was painful and had many fluid-filled blisters. Ultimately, the histology of the rash deemed the lesion non-infectious and mostly due to an inflammatory process. Specifically, ionizing radiation was used for this patient. The category of granulomatous processes is broad and there are many subtypes. Other treatment options for non-infectious granulomatous processes may include corticosteroids, phototherapy, and interferon-gamma injections. The differential for granulomatous processes is extensive and treatment should be decided on a case-by-case basis.

Head and neck cancer (HNC) accounted for 4% of all malignancies in 2022 and is often associated with tobacco and alcohol use, but the incidence of human papillomavirus (HPV)–associated HNC has steadily increased in recent decades. Unlike HPV-negative HNC, HPV-positive HNC has a favorable prognosis and survival is significantly better resulting in a large population of HNC survivors. Survivorship for HNC is of the utmost importance as there is a high burden of side effects that impact function and quality of life, and the patients with HPV HNC are living longer with the sequelae of their treatment.
