The Impact of the COVID-19 Pandemic on the Prognosis of Laryngeal Adenoid Cystic Carcinoma: A Case Report and a Literature Review.

Laryngeal adenoid cystic carcinoma (LACC) is a sporadic neoplasm, especially if supraglottic. The COVID-19 pandemic worsened the presenting stage of many cancers and impacted their prognosis negatively. Here, a case of a patient with adenoid cystic carcinoma (ACC) with delayed diagnosis and a rapid deterioration with distant metastasis due to the COVID-19 pandemic is illustrated. Next, we present a literature review of this rare glottic ACC. The COVID-19 pandemic worsened the stage of presentation of many cancers and adversely affected their prognosis. The present case had a rapidly lethal course, undoubtedly due to the diagnosis delay caused by the COVID-19 pandemic, which impacted the prognosis of this rare glottic ACC. Strict follow-up is recommended for any suspicious clinical findings, as an early diagnosis will improve the disease prognosis, and to consider the influence of the COVID-19 pandemic, especially on the timing of common diagnostic and therapeutic procedures for oncological diseases. In the post-COVID-19 era, it is important to generate new diagnostic scenarios to achieve an increasingly rapid diagnosis of oncological diseases, especially the rare ones, through screening or similar procedures.

A Rare Case of Extracranial Schwannoma of the Hypoglossal Nerve Located in the Parapharyngeal Space Mimicking a Deep Neck Abscess.

Schwannomas are neurogenic benign tumors originating from the myelin sheath of peripheral nerves, and hypoglossal Schwannomas account for 5% of nonvestibular ones. Extracranial localizations are substantially rare, especially those affecting exclusively the parapharyngeal space; for this reason, the retrostyloid neoformations could initially masquerade as a carotid tumor or deep organized neck abscess. The purpose of this report is to highlight the importance of a multidisciplinary approach in the correct management of differential diagnosis.

Smell and Taste in Children with Covid-19.

Objectives: To assess the frequency of loss of smell and taste in children during Covid-19 infection and their prevalence along with other symptoms, as well as the recovery of chemosensory function once healed. Methods: To evaluate symptoms during infection, we adapted the Scandinavian adaptation of the Multi-Clinic Smell and Taste Questionnaire and the modified Monel-Jefferson questionnaire. For smell analysis we used Odor Identification (OI) and two variants of the Odor Discrimination (OD) test, and we compared the results with those of a control group. Results: We enrolled nine patients in our experimental group and nine in our control group. Fever was the most frequent symptom (55% of cases), followed by anosmia and ageusia (44% of cases), muscle pain and asthenia (22% of cases) and diarrhea, abdominal pain, cough, and headache (11% of cases). In 11% of cases, olfactory symptoms were the only manifestation of the disease. There was no statistically significant difference in OI test and OD tests between the two groups (Children healed from Covid-19 and Control Group). Conclusion: Loss of smell and taste are the second most common symptoms of pediatric Covid-19, and they should always be tested because they can be the only manifestations of infection. Olfactory function in Covid-19 children decreases with increasing age and improves with the passage of time after illness.
