- 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
- An 11-year-old male child presented with worsening vision in his left eye. Examination and imaging revealed a left optic nerve tumour causing mass effect and optic neuropathy, without systemic evidence of neurofibromatosis. In view of the significant risk to visual acuity, a biopsy was deferred and chemotherapy was commenced. After initial stability, continued visual decline necessitated incisional biopsy. Surgical navigation was used to facilitate minimal access surgery avoiding bone removal. The system also precluded biopsy of cystic parts of the tumour, allowing successful intraoperative frozen-section confirmation of lesional tissue.
- 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.
