左颞下窝表皮样囊肿1例报告及文献复习

表皮样囊肿为胚胎发育时期遗留于组织中的上皮发展形成的囊肿,也可由于外伤或手术使上皮细胞植入而形成。颌面部好发于口底、颏下、眼睑、额、鼻、眶外侧及耳下等部位,而发生于颞下窝者少见。作者报道1例典型病例,并对其临床表现、诊断和治疗进行了讨论。     

下颌骨内表皮样囊肿1例及文献分析

表皮样囊肿为良性瘤样病变,其病因尚不明确,目前认为主要与胚胎时期遗留于组织中以及创伤性植入于组织中的上皮细胞有关。最常见的骨内部位是指骨和颅骨。发生在颌骨内的表皮样囊肿临床上较为罕见,本文报告1例发生在下颌骨内伴有一埋伏牙的表皮样囊肿,并结合相关文献探讨颌骨内表皮样囊肿的病因、临床表现、诊断以及治疗方法。

头背部多发性表皮样囊肿的临床诊治

表皮样囊肿多为单发性圆形良性肿物。本文结合1例罕见的头背部多发性表皮样囊肿病例,回顾总结国内外详细记载的相关文献分析该病,认为病史、临床表现、超声检查、CT及MRI等检查有助于术前明确诊断及选择手术方案,多发者需与皮样囊肿及Gardner综合征鉴别,而最终确诊需要依靠病理检查。手术是目前主要治疗方法,完整摘除预后好。本病可有少数恶变,生长加速或疼痛出现等可视为癌变的征象,故应尽早手术治疗。     

Lingual epidermoid cyst: case report in an infant

The purpose of this article was to present a rare case of epidermoid cyst on the ventral region of the tongue in a 15-month-old child. During clinical examination, a sessile, yellowish lesion measuring approximately 0.5 cm was noticed. The lesion had existed since the child's birth and was causing discomfort due to friction of the tongue against the alveolar ridge during mastication. The chosen treatment was total removal of the lesion. The histopathological findings confirm the diagnosis of an epidermoid cyst, characterized by the presence of: (1) a cyst cavity lined by stratified squamous epithelium with keratinization on the surface; and (2) connective tissue with a mild inflammation. The proposed treatment was considered successful as the case was solved and there was no recurrence.     

Giant epidermoid cyst of the posterior neck

A 49-year-old man was presented for evaluation of a painless mass on his right posterior neck. The mass had gradually enlarged for a 25-year period without inflammation or rupture. On physical examination, a round, nontender, soft-tissue mass, 8 cm in diameter, was noted on the right posterior neck. The neck is a common site of epidermoid cysts, but a mass more than 5 cm in diameter is rare. A contrast-enhanced neck computed tomographic (CT) scan revealed a 7.6 × 6.5 × 5.7 cm unilocular hypodense mass adjacent to the posterior neck muscles.The mass was completely excised under general anesthesia. A histopathologic examination of the excised specimen resulted in a diagnosis of an epidermoid cyst. The patient was discharged from the hospital on the third postoperative day. There were no recurrences in a 2-year follow-up period.     

Congenital epidermoid cyst arising in soft palate near uvula: a case report

Aberrant ectodermal tissues during the fetal period or acquired aberrant epithelial tissue due to trauma or surgery are thought to cause dermoid and epidermoid cysts. Their incidence is 7.0% in the head and neck region and only 1.6% in the oral cavity, where they mostly present in the floor of the mouth. On the other hand, they are extremely rare in the soft palate and uvula, and only six cases have been reported. Epidermoid cysts grow slowly and asymptomatically, and thus rarely cause oral dysfunction. However, cysts arising in the floor of the mouth can lead to developmental disorders due to impaired suckling and swallowing. This report describes a 4-week-old boy in whom an epidermoid cyst developed in the midline region of the soft palate close to the uvula. Decreased suckling ability led to a poor in body weight, so resection was performed at an early age. The histopathological diagnosis was epidermoid cyst.
