Epidermoid cysts are rarely detected malformations in the oral cavity. Their development sites are the sublingual, submaxillary, and submandibular spaces. In this paper, we report a three-month-old infant who was admitted to our hospital due upper lip swelling. Magnetic resonance imaging showed that she had a two-centimeter cystic lesion and fusion defects of orbicularis oris muscle. The cyst w...

Penile epidermoid cysts are uncommon, and a small number of cases have been reported worldwide. We present the first documented patient with a penile epidermoid cyst which consisted of multiple foci. A 37-year-old man presented to our department with a chief complaint of an asymptomatic, soft mass in the ventral part of the penis. The mass was not tender, freely movable and measuring 3 cm withi...

Epidermoid and dermoid cysts are the most common cysts of the skin. They consist 1.6-6.9% of all head and neck cysts, usually located in orbita, oral and nasal cavity [1-3], less than 0.01% of oral cavity cysts [4]. They are usually small cysts, rarely reach over 5 cm in diameter [5]. Differential diagnosis of cervical epidermoid cysts includes thyroglossal cyst, dermoid cyst, inclusion cyst, b...

BACKGROUND Tumor markers are widely applied in clinical practice, however, few serum markers have been found for intracranial tumors. Herein, we firstly report an intracranial epidermoid cyst case with extremely high level of serum CA 199. Furthermore, the relationship between CA 199 level and intracranial epidermoid cyst was closely followed for a long period. CASE PRESENTATION We report a c...

Retroperitoneal epidermoid cysts are rare. The authors report a case of an 11-year-old boy with an asymptomatic subdiaphragmatic cyst, which was found incidentally during an investigation for hypertension. At laparoscopy, the cyst was densely adherent to the diaphragm, resulting in a pneumothorax during dissection. Nevertheless, the excision and the diaphragmatic repair could be completed lapar...

Context An epidermoid cyst arising from intrapancreatic accessory spleen is rare. Herein, we report the patient who had an epidermoid cyst arising from intrapancreatic accessory spleen with typical imaging features, which was diagnosed by preoperative imaging studies and successfully treated with minimally invasive surgery. Case report A seventy-five-year-old male was referred to our hospital p...

RATIONALE Most of the intracranial epidermoid cysts are benign, but malignant lesions are occasionally reported. These lesions appear as squamous cell carcinoma and carry a dismal prognosis. Here, we report a case of a primary intracranial squamous cell carcinoma arising in a cerebellopontine epidermoid cyst. The relevant literatures were also reviewed. PATIENT CONCERNS A 53-year-old woman pr...

Epidermoid cyst in the spinal cord is a rare condition. It constitutes of only 0.6-1.1% of all spinal tumors. When they occur, the typical location is in the subdural, extramedullary space of the lumbo-sacral region.We report a forty-two -year-old female who presented with left extremity radicular pain and myelopathy. MRI of the thoracic spine,illustrated a focal fusiform enlargement of the tho...

Intracranial epidermoid cysts are one of the rare tumors of all intracranial tumors. They represent 0,2 to 1% of intracranial tumors and 7% of tumors in the cerebellopontine angle. The pineal region is exceptionally subject to such kind of tumor. Cushing was the first to report the pineal localization of the epidermoid cyst in 1928. Up to now, 85 cases of pineal epidermoid cyst were cited in th...

We describe the case of a 13-year-old boy with testicular epidermoid cyst who presented with a painless testicular mass. Epidermoid cyst of the testis is a benign, non-teratomatous tumor. It is often possible to make the diagnosis preoperatively, combining typical sonographic features with normal biochemical tumor markers. Preoperative diagnosis will allow for testis-sparing surgery and prevent...
