Yellow droopy eyes: A case of obstructive jaundice from Burkitt's lymphoma with involvement of bilateral cavernous sinus.

Burkitt's lymphoma follows a lymphogenous spread early in the disease. The central nervous system can be involved via a hematogenous route but involvement of the cavernous sinus (CS) is rare and can be misdiagnosed as other pathology of primary neoplastic, infective, or vascular origin. We present a case of a 73-year-old gentleman with painless jaundice and subjective heaviness to his eyes that progressed to partial ptosis of the left eye, complete ptosis of the right eye with diplopia, found to have disseminated Burkitt's lymphoma with bilateral deposits to the CS. Early recognition of Burkitt's lymphoma with CS involvement is important as it often signifies disseminated disease with implications on chemotherapy regimen, treatment outcomes, and survival.

Patient-induced progressive facial subcutaneous emphysema masquerading as odontogenic abscess.

Facial subcutaneous emphysema (SE) is an uncommon sequelae of dental procedures and often attributed to the use of high-speed air-driven handpieces during surgical extractions, forcing air through fascial spaces. Rarely have there been documented cases of patient-induced SE. In this case report, we present an 18-year-old woman who was referred to the emergency department with a 5-day history of progressive swelling and pain to her right cheek, following a prolonged, but simple extraction of tooth 18. While the dentist and emergency physicians were concerned about an infectious aetiology, history taking, clinical review and imaging corroborated the diagnosis of patient-induced SE secondary to habitual straw use. This report highlights the need for routine postextraction counselling of sinus precautions irrespective of extraction complexity. Additionally, emergency physicians should be aware of SE masquerading as other pathology, including odontogenic abscesses, allergic reactions, angioedema and gas-forming bacterial infections, such as necrotising fasciitis, to ensure appropriate treatment is provided to patients.

TMJ pain as a presentation of metastatic breast cancer to the right mandibular condyle.

Cancer metastasis to the oral and maxillofacial region is uncommon, and metastasis to the mandibular condyle is considered rare. We present a case of a 56-year-old woman with a history of invasive ductal cell carcinoma of the right breast, 10 years in remission, presenting with a 6-month history of symptoms typical of temporomandibular joint (TMJ) dysfunction. Imaging revealed an osteolytic lesion of her right TMJ and subsequent open biopsy confirmed the diagnosis of metastatic breast cancer. Despite the rarity of metastatic cancer to the head and neck region, it is still important for clinicians from both medical and dental backgrounds to consider this differential diagnosis, particularly in patients with a history of hormonal positive subtype of breast cancer. Given that bony metastasis can manifest even 10 years after initial diagnosis, surveillance which includes examination of the head and neck region is important, and may include routine plain-film imaging surveillance with an orthopantomogram (OPG).
