We report on a rare case of an intraosseous epidermoid cyst in the distal phalanx of the great toe with concurrent infection in a 71-year-old woman with diabetes mellitus. The lesion was initially considered simple infectious arthritis and concomitant osteomyelitis in a patient with diabetes. However, after surgery, an intraosseous epidermoid cyst originating from the nail bed and involving the articular surface of the distal phalanx was detected. The epidermoid cyst may have contributed to the infectious arthritis in the interphalangeal joint. The lesion was treated via mass excision, arthrotomy, debridement, and intravenous antibiotics.

Purpose: Epidermoid cyst may be congenital or acquired. Acquired cysts are most commonly of traumatic origin and result from an implantation or downward displacement of an epidermal fragment. Traumatic epidermoid cysts are rare tumors occurring on the nasal tip, especially resulting aesthetic procedure. So, we report a rare case of an iatrogenic epidermoid cyst in the nasal tip following rhinoplasty. Methods: A 44 - years old man had undergone rhinoplasty for several times. First time, the previous augmentation rhinoplasty and wedge osteotomy were performed nineteen months ago, lastly implant removal and unknown filler injection were performed one year ago at another local clinic. He had induration and tenderness on nasal tip and dorsum continued for 3 months. We thought that it caused by foreign body reaction with residual alloderm in nose. For removal of residual alloplastic material, open approach using transcolumellar incision was done. But, incidentally we found cystic mass on the nasal tip. Results: The findings were of an $0.8{\times}0.5{\times}0.5cm$ sized round cystic mass containing cream coloured material with a thick cheese - like consistency. The mass was completely excised and submitted for histology. This confirmed the diagnosis of an epidermoid cyst lined by keratinizing squamous epithelium. There was no induration, tenderness and sign of recurrence after excision of the mass. Conclusion: Epidermal cyst of the nasal tip region represents an unusual clinical lesion and it presents as foreign body reaction. And then, our case demonstrates that meticulous surgical approach and suture technique are the keys to prevention against iatrogenic nasal epidermoid cyst, especially in secondary rhinoplasty.

Epidermoid cyst in bony wall of external auditory canal (EAC) is a very rare pathologic condition. In addition to its extreme rarity, its positional proximity to temporomandibular joint (TMJ) might lead to clinical misdiagnosis as TMJ disorders, especially when it is accompanied by temporomandibular disorders-like symptoms. In this article, we report a patient with epidermoid cyst in anterior bony wall of EAC, which was misdiagnosed as TMJ disorder because the left TMJ pain aggravated during mastication.

Intradiploic epidermoid cysts of the cranium are rare, benign and slow growing lesion. However, these cysts may cause neurologic deficits due to mass effect. Intradiploic epidermoid cysts are thought to be derived from persistent ectodermal remnants present in the cranial bones during embryogenic development. Here, we report a case of an occipital intradiploic epidermoid cyst with posterior fossa extension. The patient developed intracranial hypertension associated with hydrocephalus due to aqueductal stenosis, and venous congestion secondary to compression of the torcular and the transverse sinus. The imaging studies included a computerized tomography[CT] venogram, which is essential for determining the pathophysiological mechanism of the clinical spectrum and for surgical planning. Near total removal was accomplished and the postoperative course was uneventful. Postoperative imaging studies demonstrated a reversal of the neural structures, but no patency of the sinus, which was presumably indicative of prolonged sinus stenosis. The patient gradually improved and was discharged free of symptoms.

Epidermoid cysts can be found anywhere in the body, particularly in areas where embryonic elements fuse together. Most cases have been reported in the ovaries, the testicles, as well as the hand and feet. Epidermoid cysts in mouth are uncommon and account for less than 0.01% of all oral cysts. The treatment of choice is complete surgical excision and prognosis is excellent. The purpose of this article is to describe two cases of an epidermoid cyst in the oral cavity mucosa and a review of the literature.

Intradiploic epidermoid cysts, like epidermoid cysts in other cranial locations, are rare. Approximately 100 intradiploic epidermoids have been reported, involving all of the cranial bones in proportion to their relative sizes. Over half erode through both tables of the cranium, creating variably sized areas of unprotected brain beneath the soft tumor. We report a case of an intradiploic epidermoid cyst of the right parietal bone that was found after minor head trauma.

In contrast to well-known imaging findings of intracranial epidermoid cysts on magnetic resonance imaging, those of intracranial squamous cell carcinoma (SqCC) are relatively unknown. We present a case of coexistence of intracranial SqCC and epidermoid cyst, with consecutive follow up over 14 months. Based on our case, a solid enhancing portion adjacent to a typically-looking epidermoid cyst may become a clue for coexistence of intracranial SqCC. An initial contrast enhancement and/or heterogeneous signal on diffusion weighted imaging may become a useful diagnostic clue, but more importantly, sudden rapid growth is important in formulating diagnosis.

표피양 낭종은 척수에 매우 드물게 발생하는 양성 병변이다. 선천적 또는 후천적으로 생길 수 있는데, 후천적 표피양 낭종은 주로 요천추부 높이에서 발생한다. 척수 자극기 삽입과 관련하여 표피양 낭종이 생긴 증례는 보고된 바 없다. 저자들은 척수 자극기 삽입술을 받았던 50세 여자 환자에서 표피양 낭종이 척수 자극기 끝의 위치와 인접한 흉추부 경막 내에 발생한 드문 증례를 경험하였기에 MRI 소견 및 문헌 고찰과 함께 보고하고자 한다.

이비인후과 영역에서 유표피낭종이 구강내에서 흔히 발생하지는 않으나 만약 존재한다면 보통 하악과 설골사이에 위치한다. 더구나 후두개에 발생한 유표피낭종은 드물게 보는 것으로서 최근 저자들은 후두개의 후두면에 발생한 유표피낭종 1례를 경험하고 경설골 인두절개술을 이용하여 종물에 접근하여 조대술을 시행한 후 성공적으로 치료된 1례를 보고하는 바이다. 환자는 46세된 남자로서 입원 이년전부터 간헐적인 인두통, 8개월부터 사성 및 1개월여의 호흡곤란을 주소로 내원하였다. 간접 후두경 검사로 후두개의 우측 후두면에 둥글고 표면이 매끄러우며 탄력성이 있고 그 크기가 구난 크기인 종물을 발견 할 수 있었다. 생검조직검사 결과 상피세포성 폴립으로 판명되어 입원하고 경설골 인두절개술을 이용하여 낭종의 조대술을 실시하였다. 술후 조직검사 결과 유표피낭종으로 판명되었고 경과가 양호하여 아무런 후유증 또는 합병증이 없이 퇴원하였기에 보고한다.

Cystic lesions of the neck are frequently encountered on clinical basis. The usual differential diagnosis includes branchial cleft, cystic hygroma, dermoid cyst, tuberculous lymphadenitis, benign detached goiterous thyroid cyst, and Cavitation epidermoid carcinoma. Most of cysts are benign and malignant cysts are rare. The most common form of cystic malignancy in the lateral neck is cystic degeneration of epidermoid carcinoma metastatic to cervical lymph nodes. Cystic neoplasia may result from malingnant changes occurring within the wall of a previously benign cyst Complete head and neck examination on the primary focus is important Especially, when palpation of thyroid is negative, thyroid carcinoma is easily overlooked. Recently, we experienced papillary carcinoma of the thyroid seen as lateral neck cyst. So we report this case with review of literatures.
