“…After the initial categories were established, studies found dermoid cysts in areas that were not included in the first categorization, and Pryor et al [ 3 ] designated such areas as “head not neck.” Dermoid cysts in this new group develop slowly and rarely show extension; therefore, Pryor suggested that minimal imaging studies sufficed for diagnosing patients. However, according to our literature review, dermoid cysts that develop in the scalp or ear regions have been reported to exhibit intracranial extension [ 4 , 5 ], suggesting that caution is important when treating these areas. The authors, therefore, found it necessary to supplement the prior categorizations of New and Erich [ 2 ] and Pryor et al [ 3 ] and developed a classification that includes the scalp and ear regions in which intracranial extension is possible ( Table 1 ).…”

BackgroundDermoid cysts are congenital tumors that are benign. Dermoid cysts with intracranial extension can cause serious neurological complications. It is important, therefore, to determine whether a patient has a dermoid cyst when their chief concern at a doctor’s visit is a mass in the head or neck area. In this study, we present a literature review of dermoid cysts and an analysis of the authors’ experiences, with the goal of providing guidance useful for the diagnosis and treatment of dermoid cysts.MethodsThis study retrospectively analyzed the medical records of 62 patients who visited the two medical clinics with which the authors are affiliated. The patients were enrolled between October 2003 and January 2017.ResultsOf the 62 patients analyzed in this study, 32 were 0 to 5 years of age (52%) and 23 were 17 years of age or older (37%). Forty-seven patients underwent 1 or more imaging study during the process of diagnosis. Thirty-two patients were suspected to have a dermoid cyst. Forty-nine patients were analyzed to determine the depth of the cyst. Bone was seen in 43 patients through imaging tests or during actual surgery, and nine of the 43 had bony problems (21%).ConclusionsThis study found that dermoid cysts were present in many adults, and that a high rate of deep lesions was observed, as well as many cases in which even the bone was affected. These results suggest, therefore, that dermoid cysts should be considered, and medical professionals should actively conduct imaging studies.

“…The occurrence of intradiploic epidermoid cysts in the temporal bone is extremely low; there are currently only 20 global [2][3][4][5][6] . and two Korean cases reported [7,8] . The authors encountered a patient, who visited the tertiary referral hospital with conductive hearing loss, due to occlusion in the external auditory canal (EAC), without other neurological symptoms.…”

Intradiploic epidermoid cyst of the skull, despite being rare and representing less than 1% of all intracranial tumors, is a benign lesion that is derived from an ectodermal cell rest within the cranium. The frontal and parietal bones are the most common sites for the cyst; however, the temporal bone, although rarely, is also involved. Intradiploic epidermoid cysts have slow growth rates and often grow to enormous sizes without producing any measurable neurological symptoms. For treatment, a complete removal of the cyst with its capsule is important to avoid recurrence. Very rare malignant transformations of the cysts have been reported, generally in cases with repeated recurrences or infections. A 16-year-old female patient was diagnosed with a temporal bone intradiploic epidermoid cyst behind the left mastoid cavity, which was successfully removed through a transmastoid approach.
