Dermoid cysts are developmental cysts and considered to develop from enslavement of epithelial debris in the midline during closure of the mandibular and hyoid brachial arches. These cysts are painless, slow growing and most commonly occur in young adults with no gender predilection. They are uncommon in the head and neck region. Oral dermoid cysts are found usually in the submental or sublingual triangle in variable relation to mylohyoid, geniohyoid, and genioglossus muscle. The cyst is lined by epidermis like epithelium and contains dermal adnexal structures in the cyst wall. We report a case of dermoid cyst arising in the sublingual region of a young adult male with abundance of hair which is rare finding.

Purpose: The O-RADS malignancy risk stratification of typical ovarian dermoid cysts by using a 10 cm threshold is based on expert consensus rather than analysis of objective clinical data. This comprehensive scoping review consolidated all currently available studies evaluating typical benign ovarian dermoid cyst size and risk for malignant transformation.
Methods: A systematic review of MEDLINE, Embase, Scopus and the Cochrane library was performed from inception to January 14, 2024, using PRISMA-ScR guidelines.

On magnetic resonance imaging( MRI) examination, the anterior mediastinal tumor showed homogeneous high signal intensity on T1-weighted images and a combination of high and low signal intensities on T2-weighted images.
