Asymptomatic idiopathic submandibular abscess — a diagnostic conundrum

Abstract
Background
Facial and neck abscesses are often seen in patients. Usually, they are linked to a primary source of infection in orofacial, dental, or otolaryngeal region and are associated with the classic signs and symptoms of infection and inflammation. We came across a case of submandibular abscess whose behavior pattern defied the typical trends.

Case presentation
A completely asymptomatic boy reported with a huge swelling below the left-side lower jaw, extending onto the neck region. The history of swelling was acute with progressive nature since the last 5–6 days. His clinical examination and the laboratory investigations were quite routine without any deviation from usual. Despite exploring for all probable causes, authors could not find the definitive reason for such unusual presentation.

Conclusion
Although the patient was cured with conventional medical and surgical treatment for head and neck space infection, the pathophysiology of such asymptomatic and idiopathic abscess remained a diagnostic dilemma.
