Benign cervical schwannoma with tracheal invasion.
Einstein (Sao Paulo)
February 2024
Schwannomas commonly develop in the cervical region, 25% - 45% of cases are diagnosed in this anatomical region. Tracheal neurogenic tumors are exceedingly rare and can be misdiagnosed as invasive thyroid carcinomas or other infiltrating malignancies when present at the level of the thyroid gland. Here, we present a case of synchronous benign cervical schwannoma with tracheal invasion and papillary thyroid carcinoma in a patient who was initially hospitalized for COVID-19.

We described here an 18-year-old male who reported a cervical nodule. Magnetic resonance images revealed a mass in the ethmoidal sinus corresponding to rhabdomyosarcoma.

In another cancer subtypes, positive-PNI suggests increased poor prognosis; however, the role of isolated positive-PNI salivary gland MEC can still be better investigated as a risk factor.

- Pediatric salivary gland fine-needle aspiration (FNA) is rare, typically involving more inflammatory conditions than tumors, and this study evaluated the Milan System for Reporting Salivary Gland Cytopathology (MSRSGC) in a large international cohort.
- The study analyzed 477 FNA specimens from children and categorized them using the MSRSGC, reporting varying risks of malignancy (ROM) for each category; notable findings included a significant occurrence of benign tumors like pleomorphic adenoma.
- Results showed that the ROM for pediatric salivary gland FNA categories generally mirrored those found in adults, indicating that the MSRSGC framework is a reliable tool for assessing these cases despite some institutional variability. *
Parotidectomy and neck dissection in locally advanced and relapsed cutaneous squamous cell carcinoma of the head and neck region.
Braz J Otorhinolaryngol

Objective: To investigate the prognostic factors to developing parotid and neck metastasis in locally advanced and relapsed Cutaneous Squamous Cell Carcinoma (CSCC) of the head and neck region.
Methods: Single-center retrospective cohort study enrolling consecutive patients with advanced CSCC from 2009 to 2019. Seventy-four cases were identified.
