ABSTRACT
Epidermoid cysts are common cystic lesions in the skin, ovaries, and testicles, but their occurrence in the oral cavity is uncommon. They consist of cysts delimited by a fibrous capsule without cutaneous annexes and are lined by stratified squamous epithelium. The differential diagnosis includes ranula, dermoid cysts, and lingual thyroid. Despite their benign presentation, these cysts can cause functional limitations, requiring special clinical attention for extensive lesions located in regions that preserve vital structures. This paper aims to report a case of epidermoid cyst in patient with swallowing and breathing difficulty, highlighting the clinical and surgical planning.

Microscopic findings: (a) the lining of the cyst is composed of an epithelium which is flattened and contains a granular layer of keratohyalin granules, Haematoxylin and Eosin, 100x, and (b) foci of rupture and keratin exposed to the adjacent capsule and reaction composed of macrophages and foreign body giant cells (for keratin exposed), Haematoxylin and Eosin, 400x.

Mentions: The ovoid cystic mass was macroscopically observed to be opened and without any content. It was measured to be 5.0 × 3.0 × 0.2 cm and it had brown pigmentation with a few whitish areas. Microscopic examination revealed a cystic cavity with a capsule composed of dense fibrous connective tissue, lined by stratified squamous epithelium resembling epidermis (Figure 4(a)). There were no skin appendages in the capsule. The lesion contents were represented by concentric blades of orthokeratin. A breach on the cyst wall with chronic granulomatous inflammation and multinucleated giant cells was also observed (Figure 4(b)), including keratin, being the final diagnosis of a ruptured epidermoid cyst, with granuloma to the foreign body (keratin).
