OBJECTIVE To determine the safety and efficacy of laparoscopic management of ovarian dermoid cysts based upon our ten years' experience. METHODS Charts of 81 patients who underwent laparoscopic removal of dermoid cysts since March 1988 at Stanford University Medical Center or the Center for Special Pelvic Surgery in Atlanta were reviewed retrospectively. RESULTS Ninety-three dermoid cysts w...
Dermoid cysts are rare congenital tumors that occur primarily at the midline at a characteristic intradural location. However, dermoid cysts located at extradural and lateral regions have been rarely reported until now. In the present study, the authors demonstrate the unusual instance of an intracranial extradural dermoid cyst at the lateral sphenoid ridge. A 53-year-old woman admitted because...
Dermoid cysts of the head and neck are rare congenital benign tumors. According to the literature they represent about seven percent of all dermoids and less than one percent of all intracranial neoplasms. Extradural dermoid cysts are very rare. We report a case of intracranial extradural dermoid cyst of mastoid bone. We believe that this is the second documented extradural dermoid cyst, the fi...
INTRODUCTION Dermoid cysts are the most common orbital cystic lesions seen in children. While superficial orbital dermoid cysts present early in life, deep dermoid cysts remain clinically occult until adolescence or adulthood. We here present a case of a deep orbital dermoid cyst in a Nigerian child that became symptomatic early in infancy. CASE PRESENTATION A female Nigerian infant of Yoruba...
purpose : to review periocular dermoid cysts to determine distribution of demographic factors, and tumor location methods : in this retrospective, observational case series in a tertiary-care hospital, we reviewed all cases of histopathologically verified periocular dermoid cysts at our institution between 2003 and 2011. the study endpoints included: age, gender, and tumor location. results : t...
Both lipomas and dermoid cysts of the cerebellopontine angle are rare tumors. These tumors differ in their embryological origin but share similar features on imaging. Both of these congenital lesions can be found in the cerebellopontine angle (CPA), and symptomatic clinical presentation is dictated by the location of the lesion. This paper demonstrates a unique case in which a CPA lipoma was mi...
Dermoid cysts are rare, benign lesions of embryological origin that represent 0.1-0.7% of all intracranial tumors. They are mainly located in the supra tentorial space, especially in the parasellar region. Their location in the posterior fossa remains uncommon. Rupture of intracranial dermoid cysts is a rare phenomenon. We present a case of dermoid cyst, which had ruptured into ventricular syst...
The growth of dermoid cysts at the floor of the mouth is considered a rare condition. Typically, intra-oral dermoid cysts present as non-tender, slow growing masses at the sublingual, submental and submandibular region. We report a case of a young adult male who presented at our hospital with a sublingual cyst superimposed with acute infection and failed antibiotic treatment. The cyst was excis...
The purpose of this paper is to discuss the pathology and clinical features of limbal der moids and to illustrate these features with case records from the Wills Eye Hospital. A dermoid may be defined as a solid con genital tumor consisting of mesoblastic tis sue (fibrous and fatty usually) covered by ectoderm (skin) and invaded by ectodermal derivatives, that is, hair follicles, sebaceous a...
