Antrochonal polyp (ACP) is a benign, rare, and generally unilateral tumor which originates from the maxillary sinus mucosa. Bilateral ACP is extremely rare. Only few cases have been documented in the literature until 2018. The authors report the case of a 44-year-old women, who presented with a bilateral progressive nasal obstruction for the past 2 years, slight headache and a decreased sense of smell has been started in last four months. Nasal endoscopy revealed pale polypoidal masses in nasal cavities, arising from each middle meatus and extending to the nasopharynx. Computed tomography of the paranasal sinuses revealed the presence of soft-tissue masses in the maxillary sinuses, passing through the maxillary ostium, and extending into the corresponding nasal cavities, and posteriorly upto the nasopharynx. The other sinuses were normally aerated. The tumors were removed surgically with a nasal endoscopy technique. Histopathology examination the two lesions revealed benign inflammatory nasal polyps.

Congenital nasal pyriform aperture stenosis (CNAPS) is a rare cause of pediatric nasal airway obstruction that clinically mimics choanal atresia in a neonate. CNPAS is suspected clinically and confirmed with CT scanning. Early diagnosis and management is essential for this potentially life-threatening condition. Because of the association this anomaly has with other midline defects, such as holoprosencephaly, it is important to recognize it and pursue a thorough workup. Patients can be managed conservatively or surgically. Surgical treatment is usually reserved for those patients that fail conservative treatment. We present a case of CNPAS, to highlight the importance of recognizing the classic signs of CNPAS on cross-sectional imaging to prevent fatal outcome.

Lipomas are the most common mesenchymal tumours of adulthood, infrequently occur in the head and neck region. Lipomas are typically slow-growing tumours, only a few grow to an exceptionally large size. Surgical excision of a lipoma is the gold standard and the definitive treatment modality. In the present study two rare cases of a giant lipoma of lateral and anterior cervical region are presented.
