Proposed computed tomography severity index for the evaluation of invasive fungal sinusitis: Preliminary results.

Background: Invasive fungal sinusitis (IFS) can present as a mild disease to life-threatening infection. A recent surge in cases was seen due to the coronavirus disease 2019 (COVID-19) pandemic. Many patients require surgical debridement and hence imaging [contrast-enhanced computed tomography (CECT) of the paranasal sinuses (PNS)] to document the extent of the disease.

Malignant Degeneration of a Peripheral Nerve Sheath Tumor in the Neck Region.

Malignant transformation of neurofibromas into malignant peripheral nerve sheath tumors (MPNST) is a rare but aggressive phenomenon, particularly in the head and neck region, and is associated with a poor prognosis. The primary treatment modality is surgical excision, often followed by radiotherapy. This is a case report of MPNST in the neck, with long-term follow-up.

Challenges in the Cytodiagnosis of Intraparotid Schwannoma.

Clear cell tumors of parotid gland encompass a wide spectrum of neoplasms, including benign and malignant epithelial neoplasms. Additionally, tumors from adjacent structures such as paraganglioma, and metastatic neoplasms may also show clear cells. Overlapping cytological features may cause difficulty in diagnosis.
