Successful Antiviral Treatment for Chronic Adenoiditis Caused by Herpes Virus in a Pediatric Patient: A Case Report.

BACKGROUND The adenoids are lymphatic tissue located in the nasopharynx and play a role in upper-airway immunity. Inflammation of the adenoids is called adenoiditis, which can cause a variety of symptoms. This is a common condition and is due to acute viral or bacterial infection. Most patients experience mild symptoms of upper-respiratory tract infection with a self-limiting course. CASE REPORT A 5-year-old female patient was brought into the clinic by her parents with concerns regarding hearing and sleep. Clinical assessment was consistent with persistent otitis media with effusion and sleep-disordered breathing. She was scheduled for surgery, including nasendoscopy, adenoidectomy, and bilateral grommet insertion. During surgery, direct visualization of the postnasal space showed complete obstruction by hypertrophic, inflamed adenoids covered in a thick, white film. A biopsy was taken, which detected herpes virus cytopathic effect. A diagnostic workup excluded a neoplastic process and other bacterial or fungal infections. A trial of oral antiviral medication was successful and follow-up nasendoscopy showed resolution of adenoid hypertrophy. CONCLUSIONS Direct visualization of the postnasal space, with a transoral mirror or 120-degree endoscope, prior to adenoidectomy can aid diagnosis. Adenoiditis may be caused by a wide range of organisms, including herpes virus. Active mucopurulent discharge should raise concern for infection by bacteria, fungi, or virus. Previous research on viral infection of the adenoids have been in asymptomatic patients with presumed latent infection and undergoing elective adenoidectomy. To our knowledge, this is the first paper to report on successful treatment with antiviral medication alone.

Primary orbital extraskeletal osteosarcoma.

The authors describe a case of orbital extraskeletal osteosarcoma. A 78-year-old man with a history of rheumatoid arthritis on long-term corticosteroids had a left medial canthal basal cell carcinoma excision followed by adjuvant radiotherapy. Twelve months later, he re-presented with a large rapidly-growing calcified mass involving his left medial canthus and orbit. An incisional biopsy demonstrated an infiltrate of atypical cells exhibiting mitotic activity with a rosette arrangement around partially calcified necrotic tissue. The patient underwent orbital exenteration and a partial maxillectomy. Histopathology demonstrated an extraskeletal osteosarcoma. It is extremely rare for this tumor to occur in the orbit. Immunosuppression and adjuvant radiotherapy were possible predisposing factors in the development of this tumor. Extraskeletal osteosarcoma (ESOS) is a malignant tumour that produces osteoid. It develops in soft tissue without continuity to bone or periosteum. It is rare and comprises fewer than 5% of all osteosarcomas. Extraskeletal osteosarcoma primarily affects patients above 50 years of age and has a poor prognosis. In this report, we describe the clinical, radiologic, and pathologic records of a rare case of primary ESOS of the orbit.
