- Orbital cellulitis is an infection of the soft tissues lying behind the orbital septum. The etiologic agents differ across age group, but gram-positive cocci colonizing the skin and the nasopharynx, such as Staphylococcus and Streptococcus species, are most commonly identified in children. Haemophilus influenzae, a gram-negative facultative anaerobe, was frequently identified before the introduction of the Haemophilus vaccine in 1985. We report the case of a 15-year-old man who presented with a severe orbital cellulitis complicated by a subperiosteal abscess (SPA) secondary to Capnocytophaga sputigena.
- Rosai-Dorfman disease is a rare systemic histioproliferative disease characterized clinically by cervical lymphadenopathy and pathologically by lymph node sinuses containing histiocytes with intact phagocytosed lymphocytes (emperipolesis).1
- We report a case of a 61-year-old female visiting from Hungary with undifferentiated nonkeratinizing nasopharyngeal carcinoma (NPC). She presented to the ophthalmology clinic with no light perception in her right eye. She reported a 2-month history of right eye protrusion and swelling, right-sided hearing loss, and right temporal pain. Her past medical history was significant for a hysterectomy. She did not take any medications and did not have any drug allergies. There was no family history of head or neck cancer.
