“…It is noted that the average dimension of CECs is 5.5 × 3.6 cm, 10 and the most giant 1 located in the frontal region was approximately 5 cm in diameter 11 . At the time of this writing, we find that only 6 asymptomatic cases of CECs with small size were reported occurring in the frontal region (1 case in 2015 and 5 cases in 2016) 9,12 …”

In the setting of trauma with cerebral edema, stroke with bleeding requiring removal of skull, delayed cranioplasties were necessary at a secondary stage.…”

Epidermal or epidermoid cysts are 1 of the most frequent benign masses, they rarely grow to a huge size, and only a few cases have been reported. We report a rare case of a 52-year-old man with giant neoplasm growing invasively in the frontal region, including both intracranial and extracranial extensions, and caused extensive brain deformation and skull lesions. It is worth noting that the patient did not present any significant neurological symptoms and deficits for more than 40 years on admission. A combination of gross total tumor resection and cranioplasty was performed. The patient was satisfied with the results of the surgery, and no evidence of recurrence or complications were found in the 2 years follow-up. The authors reported the case not only to propose the first-stage aesthetic treatment option for this unusual mass on the scalp but also hinted at the vigilance and importance of systematic monitoring of the small skull mass for avoiding the potential risk of tumor progression, malignant transformation, operative trauma, and financial burden.

“…Intradiplopic orbital dermoid and epidermoid cysts are rare, benign tumors, with only 49 cases reported in the literature.

Purpose: The purpose of this study was to characterize intradiploic dermoid and epidermoid orbital cysts to determine any differences in clinical, radiographic, or surgical features. Methods: A retrospective review was performed of patients presenting with intradiplopic dermoid or epidermoid cysts. Additionally, a complete review of the literature was performed to identify cases of intradiplopic orbital dermoid and epidermoid cysts. Data collected included age, sex, presenting symptoms, location of intradiplopic cyst, ophthalmic findings, treatment, and follow-up. Clinical features of dermoid versus epidermoid cyst were compared. Additionally, machine-learning algorithms were developed to predict histopathology based on clinical features. Results: There were 55 cases of orbital intradiploic cysts, 49 from literature review and six from our cohort. Approximately 31% had dermoid and 69% had epidermoid histopathology. Average age of patients with dermoid cysts was significantly lesser than that of patients with epidermoid cysts (23 vs. 35 years, respectively; P = 0.048). There was no difference between sex predilection, presenting symptoms, radiographic findings, or surgical treatment of dermoids and epidermoids. The majority of patients (64%) underwent craniotomy for surgical removal. Machine-learning algorithms KStar and Neural Network were able to distinguish dermoid from epidermoid with accuracies of 76.3% and 69%, respectively. Conclusion: Orbital intradiploic cysts are more commonly epidermoid in origin. Dermoid cysts presented in younger patients; however, there were no other significant differences in features including ophthalmic or radiographic findings. Despite similar features, machine learning was able to identify dermoid versus epidermoid with good accuracy. Future studies may examine the role of machine learning for clinical guidance as well as new surgical options for intervention.

“…About 25% of all epidermoid cysts present in intradiploic location as expansible lesions, hence to our knowledge, incidental presentation as a soft swelling on occipital bone has been reported only twice in the scientific literature in English. [ 1 2 3 4 ] We present a young patient with an intradiploic epidermoid cyst presented as a soft swelling on occipital bone and discuss its etiology, histology, radiology, and management strategies. A 27-year-old man admitted to clinic with a history of softness and irregularity on the back of his head just behind his left ear.…”
