A case of malignant schwannoma arising in a paranasal sinus is reported. In this case, histological hallmarks were lost because of the poorly differentiated nature of the tumour. Immunohistological techniques were applied to the diagnosis, confirming the neural origin of this tumour. Malignant schwannoma is a relatively rare disease in the nasal cavity and paranasal sinuses. For the treatment of this tumour, wide resection is recommended. In this patient, radical resection of the maxilla with orbital and ethmoid exenteration was performed. The patient recovered uneventfully with no evidence of disease three years after surgery.

Nuclear protein in testis (NUT) carcinoma represents a highly aggressive, poorly differentiated carcinoma that is genetically defined by rearrangement of NUT gene. The histomorphological appearance ranges from entirely undifferentiated carcinoma to carcinoma with prominent squamous differentiation. NUT carcinoma can display neuroendocrine features. Although it is typically distributed along the midline axis, it may manifest in nonmidline locations. The majority of patients develop rapidly disseminated disease. We illustrate 2 cases of NUT carcinoma, one located in the lung, which closely resembled a neuroendocrine carcinoma, and the other one with assumed lung origin demonstrating metastatic dissemination with diffuse bone involvement, which was clinically first suspected to be a hematological malignancy. Due to its undifferentiated nature, NUT carcinoma may be confused with many entities. NUT immunohistochemistry is considered to be sufficient for the diagnosis. Fluorescence in-situ hybridization analysis and next-generation sequencing are currently used to confirm the diagnosis.

Paranasal Sinus Surgery

The pediatric nasal cavity and paranasal sinuses, when compared to those in adults, differ not only in size but also in proportion. Knowledge of the unique anatomy and pneumatization of children's sinuses is an important prerequisite to understanding the pathogenesis of sinusitis and its complications. It is also important in evaluation of radiographs and in planning surgical interventions. In order to study the development of the paranasal sinuses in children and relate clinical anatomy to sinus surgery, the sinuses in 102 pediatric skulls and cadaver heads were measured. The results were classified by stage of development into 4 different age groups: newborn and 1 to 4, 4 to 8, and 8 to 12 years. The characteristics of each group and their clinical importance for paranasal sinus surgery are described.
