Dermoid Cyst

Abstract

Dermoid cysts are embryonic lesions usually observed in the lateral eyebrow region and the midline nose and neck areas. Communication of these lesions with the central nervous system is rare and occurs in the nasal region. There are few clinical reports of temporal dermoid cysts presenting with intracranial extension, and we present a 15-year-old girl with a fronto-orbital dermoid cyst with intracranial extension and bone erosion. Her presenting symptom was a lacrimation reduction of the left eye. Excision of the cyst was done using a coronal approach because of its extension and localization.

Intradiploic Dermoid Cyst of the Lateral Frontotemporal Skull: Case Report and Review of the Literature

“…While midline dermoids are not infrequently found to invade the cranium, there are fewer than 20 case reports which describe lateral frontotemporal dermoids with associated sinus tracts and bony invasion, of which 7 have extended intracranially [1,2,5,7,8,9,10,11,12,13,14,15]. Intradiploic dermoids represent between 0.04 and 0.7% of all cranial tumors [17].…”

“…They may appear as a lytic defect in the skull, giving a wide differential diagnosis by imaging alone. Frontotemporal dermoid cysts associated with sinus tracts or bony invasion are extremely rare, with only 20 case reports described in the literature [1,2,5,7,8,9,10,11,12,13,14,15]. We present a report of a rare intradiploic frontotemporal dermoid, without soft tissue extension, in the cranium of a 2-year-old male.…”

“…Intradiploic dermoid cysts are a rare subtype of the frontotemporal dermoids accounting for 0.04-0.7% of all cranial tumors, occurring most commonly at the bregma [1]. They may appear as a lytic defect in the skull, giving a wide differential diagnosis by imaging alone.…”

“…They typically occur in childhood, during the first or second decade of life. Dermoids represent approximately 1% of all craniofacial space-occupying lesions and are commonly found in the periorbital, nasoglabellar, and frontotemporal regions [1]. While dermoid cysts are slow-growing in nature, they can be associated with serious complications [2,3,4,5,6].…”

Surgical management of a dermoid cyst with mandibular gland tissue in a Japanese Black calf

“…This abnormality has been reported in humans [ 19 , 22 , 25 , 27 , 30 ], dogs [ 6 , 8 , 20 , 24 , 29 , 34 , 38 ], cats [ 2 , 12 , 20 , 31 , 36 ], horses [ 18 ], goats [ 13 ], sheep [ 33 ], buffalo [ 9 , 39 ], and camels [ 26 ]. Lesions occur in young animals, predominantly on the midline of the head and neck [ 16 , 21 ].…”
