Two brothers with human papillomavirus-positive oropharyngeal squamous cell carcinoma of the tonsil: A case report.

Oropharyngeal squamous cell carcinoma is a distinct subtype of head and neck cancer that has become increasingly linked to human papillomavirus over the last four decades. Described is the case of two brothers diagnosed with human papillomavirus-positive oropharyngeal squamous cell carcinoma 6 years apart. The first brother, R.M., presented with an 8-month history of tonsillar swelling, found to be stage III human papillomavirus-positive oropharyngeal squamous cell carcinoma. Despite delayed treatment with chemoradiation, he developed metastatic disease and succumbed to his illness. The second brother, K.M., presented only 3 weeks after the development of neck swelling given his family history, which was also diagnosed as stage III human papillomavirus-positive oropharyngeal squamous cell carcinoma. Following prompt chemoradiation and neck dissection, K.M. has remained in remission for 9 years. Literature has yet to characterize this degree of familial clustering among human papillomavirus-positive oropharyngeal squamous cell carcinomas. Hence, this introduces the possibility of a genetic predisposition to human papillomavirus's oncogenesis in the oropharynx. This case emphasizes the importance for clinicians to stay vigilant of the family history of human papillomavirus, as well as poses significant implications for future research investigating the interaction of genetic aberrations on human papillomavirus's oncogenic process.

Sinonasal Plasmablastic Lymphoma Arising in the Setting of Recurrent Nasal Polyposis in an Immunocompetent Individual.

Plasmablastic lymphoma (PBL) is an aggressive, rare variant of B-cell lymphoma typically associated with human immunodeficiency virus and other immunocompromised populations. Most commonly found in the oral cavity, PBL can occasionally originate in the sinonasal tract. Diagnosis of PBL is difficult due to overlapping features with other malignancies; however, early detection and treatment are imperative given its aggressive clinical course. When in the sinonasal tract, the diagnostic process can be further complicated if the patient has a history of recurrent nasal polyposis. Described is the case of a 57-year-old immunocompetent male who initially presented with benign nasal polyposis, only to return a year after sinus surgery with a unilateral sinonasal mass consistent with PBL. As literature has yet to characterize this phenomenon, this article presents the first case reported of sinonasal PBL arising in the setting of recurrent nasal polyposis. This case emphasizes the importance of investigating sinonasal masses showing laterality, maintaining a high index of suspicion for malignancy, and keeping close surveillance of the patient after treatment of PBL.

Chronic invasive fungal sinusitis: a report of two atypical cases.

The purpose of this article is to describe a chronic variant of invasive fungal sinusitis (IFS) and discuss its management. This is a retrospective review of two cases of IFS that were characterized by atypical clinical courses. Patient 1 was a 75-year-old man with noninsulin-dependent diabetes mellitus who came to us with a 5-month history of headache. Computed tomography detected an opacified left sphenoid sinus. After the man failed to respond to medical therapy, he underwent a left endoscopic sphenoidotomy. Pathologic examination revealed that septate, branching fungal hyphae had invaded the soft tissues. The patient was started on oral itraconazole, but later switched to intravenous amphotericin B in response to intracranial extension. The man's disease stabilized, but he died a little more than 1 year later of unrelated causes. Patient 2 was an otherwise healthy 41-year-old woman who came to us with nasal congestion and unilateral nasal polyps. She underwent endoscopic sinus surgery. Pathologic examination identified granulomatous sinusitis and septate, branching fungal hyphae that had invaded the soft tissue of the middle turbinate. The patient was not treated with systemic antifungal medications because of the localized nature of the fungal invasion and the lack of bone invasion or erosion. She has now been symptom-free for 5 years. These two cases demonstrate that IFS can appear in a chronic variant form that is characterized by an indolent course and histologic evidence of tissue invasion by fungal hyphae. The type of treatment is dependent on the extent of the disease on initial examination and the rapidity of its progression.
