Studies of a pedigree with limbal dermoid cyst.

ABSTRACT: AIM:To study clinical features and gene mutations within the paired-like homeodomain transcription factor 2 (PITX2) gene in a pedigree of bilateral limbal dermoids. METHODS:Complete eye examinations have been performed on each individual of the family. Exons of paired-like homeodomain transcription factor 2 (PITX2) were amplified by polymerase chain reaction, sequenced, and compared with a reference database. RESULTS:We described the phenotype, clinic findings in a family with two affected members. The masses of the proband's eyes were excised surgically demonstrating a dermoid cyst by histopathological examination. No mutation was detected in the gene PITX2 in this pedigree. CONCLUSION:A family of limbal dermoid cyst was reported. In addition, no pathogenic sequence variations were found in PITX2, indicating that this phenotype in this family is a distinctive entity.

Dermoid Cyst of Nasal Tip and Nasal Septum.

Project description:AbstractDermoid cyst is a congenital and benign disease with most occur on the head and neck. It is rarely that occur on the nasal tip and nasal septum at same time and rarely repair of using nasal septum mucosa. The authors treated a child with dermoid cyst in the nasal tip and septum. Only the dermoid cyst at the tip of the nose caused the change of appearance. Dermoid cyst of nasal septum did not cause any clinical symptoms. She underwent excision of the dermoid cyst at the tip of the nose and endoscopic surgery for the dermoid cyst in the nasal septum and used the nasal septum mucosa for repair at the same time. After 6 months of recovery, the appearance of the nasal tip recovered well without obvious scar, the nasal septum area recovered well, and the local stoma was unobstructed without recurrence. The authors found that this kind of nasal septal cyst with no clinical symptoms can achieve good therapeutic effect through endoscopic surgery and repair of using nasal septum mucosa, with less damage, rapid recovery, and good prognosis.

Fimbrial dermoid cyst with elevated CA19-9 levels: A case report.

Project description:We report the case of a 39-year-old woman who presented in an acute setting with pelvic pain, an adnexal mass on imaging and a high CA19-9 level. She was taken for surgery, where a large dermoid cyst was found at the fimbrial end of a fallopian tube at the time of laparoscopy, with no apparent connection to either ovary and absence of ovarian necrosis. This was corroborated on final histology. Dermoid cysts in aberrant locations are usually reported at Caesarean section or during laparoscopic sterilisation and thus, understandably, a pre-operative CA19-9 level is rarely available. That and the rarity of these 'ectopic dermoids' make it hard to give further support for a causative association with the high tumour marker levels. Some authors suggest that auto-amputation of a dermoid cyst or part thereof and subsequent reimplantation may give rise to this phenomenon, and thus the term 'wandering dermoid' has been applied to similar situations. This is what we postulated as the cause in our case. It is likely that a full understanding of the aetiology of wandering dermoid cysts will remain elusive, given the paucity of cases.

Superficial solitary fibrous tumor masquerading as a dermoid cyst: a case report.

Project description:BackgroundSolitary fibrous tumors (SFTs) are relatively rare spindle cell neoplasms uncommonly seen in dermatology practice. Initially discovered as a pleural tumor, SFTs have also been found in extra-pleural sites including the skin and soft tissues. When arising within the dermis or subcutis they are termed superficial SFTs, where they often present as solitary, unilateral, slow growing superficial masses. Histologically, they are composed of spindle cells arranged in a "patternless" pattern with hemangiopericytoma-like vessels dispersed throughout. Historically, CD34, CD99 and Bcl-2 immunohistochemical (IHC) stains were used to differentiate SFTs from other spindle cell neoplasms, however these markers are not entirely specific. Recent discovery of a disease defining NGFI-A binding protein 2 (NAB2)-signal transducer and activator of transcription 6 (STAT6) fusion gene has led to the use of STAT6 IHC staining to help verify the diagnosis of SFTs, particularly in unexpected sites.Case descriptionWe report a case of a 23-year-old woman with a slowly growing lateral supra-orbital mass, clinically concerning for a dermoid cyst, which was subsequently discovered to be a SFT on pathologic examination, with the diagnosis being verified by STAT6 immunostaining.ConclusionsSFTs are rarely encountered in dermatologic practice, however, must be kept on the differential of subcutaneous nodules, including those occurring in young adults. Due to the rarity of these tumors in clinical practice, a proposed algorithm for the approach to management of SFTs is included, guided by a validated, histology-driven, metastatic risk assessment tool, to help guide other clinicians confronted by these tumors.

Atypical intraorbital dermoid and epidermoid cyst: A single institution cross-sectional retrospective study.

Project description:PurposeIntraorbital epidermoid and dermoid cyst (DC) has been reported in the literature rarely. The current study evaluates clinicopathologic, radiologic, and management of intraorbital DC cases over ten years.MethodsIn this cross-sectional study, the medical records of patients with intraorbital DC treated at the academic referral center for ocular surgery were retrospectively reviewed. Data reviewed included the patient's demographic characteristics, clinical features, imaging, surgical technique, and pathology report.ResultsNine patients with a rare presentation of intraorbital DC were reviewed within the study period in five presentations (five intraosseous, one intraconal, one dumbbell-shaped with a large part in anterior orbit, one juxta levator palpebral muscle, and one recurrent case with intracranial extension). They ranged from 8 to 53 years of age, with a median of 29 years, and five (55.6%) were female. Histopathological evaluation revealed two cysts were epidermoid.ConclusionThe current study provides more clinical and radiologic manifestations of rare presentations of DC that highlight the importance of high clinical suspicion in the approach to atypical DC.

Effects of Perceptual Learning on Deprivation Amblyopia in Children with Limbal Dermoid: A Randomized Controlled Trial.

Project description:Limbal dermoid (LD) is a congenital ocular tumor that causes amblyopia and damages visual acuity (VA) and visual function. This study evaluated the therapeutic efficacy of perceptual learning (PL) toward improving contrast sensitivity function (CSF) and VA. A total of 25 children with LD and 25 normal children were compared in terms of CSF and VA. The LD group was further randomly allocated into two arms: nine underwent PL combined with patching and eight underwent patching only; eight patients quit the amblyopia treatment. The primary outcome was the area under log CSF (AULCSF), and the secondary outcome was the best corrected VA (BCVA). The CSF was obviously reduced in the LD group compared with that in the normal group. Moreover, the difference in the changes in the AULCSF between the PL and patching groups after 6 months of training was 0.59 (95% CI: 0.32, 0.86, p < 0.001), and the between-group difference in VA at 6 months was −0.30 (95% CI: −0.46, −0.14, p < 0.001). Children suffering from LD with amblyopia exhibited CSF deficits and VA loss simultaneously. PL could improve CSF and VA in the amblyopic eye better than patching.

Transpterygoid approach to a dermoid cyst in pterygopalatine fossa.

Project description:Objective To describe a case of dermoid cyst arising from the pterygopalatine fossa and review the literature. Methods We report a case of a 23-year-old man who suffered a car accident 2 years before otolaryngologic attendance. He had one episode of generalized tonic-clonic seizure and developed a reduction of visual acuity of the left side after the accident. Neurologic investigation was performed and magnetic resonance imaging revealed an incidental finding of a heterogeneous ovoid lesion in the pterygopalatine fossa, hyperintense on T2-weighted imaging. Results Endoscopic sinus surgery with transpterygoid approach was performed. The ovoid lesion was noted in the pterygopalatine fossa. Puncture for intraoperative evaluation showed a transparent thick fluid. Surprisingly, hair and sebaceous glands were found inside the cyst capsule. The cyst was excised completely. Histologic examination revealed a dermoid cyst. The patient currently has no evidence of recurrence at 1 year postoperatively. Conclusion This unique case is a rare report of a dermoid cyst incidentally diagnosed. An endoscopic transnasal transpterygoid approach may be performed to treat successfully this kind of lesion. Although rare, it should be considered in the differential diagnosis of expansive lesions in the pterygopalatine fossa, including schwannoma, angiofibroma, esthesioneuroblastoma, osteochondroma, cholesterol granuloma, hemangioma, lymphoma, and osteoma.

A dermoid cyst misdiagnosed as a lipoma due to atypical magnetic resonance images: a case report.

Project description:BackgroundDermoid cysts are well-known lesions that manifest as subcutaneous tumors around the lateral sides of the eyebrows in young patients. Computed tomography or magnetic resonance imaging (MRI) is often performed to confirm the diagnosis. On the other hand, a lipoma is usually a circular lesion, which is sometimes observed in the upper part of the face. The signals of both T1-weighted and T2-weighted images of MRI of a lipoma are, in general, relatively highly homogenous, and the signals decrease in fat-suppressed images. Therefore, differential diagnosis between a dermoid cyst and a lipoma is usually made with MRI, especially based on fat-suppressed images. Here, we present a case of misdiagnosis of a dermoid cyst as a lipoma because of atypical magnetic resonance images.Case presentationWe report a case of a 24-year-old Japanese woman with a dermoid cyst around the lateral edge of the eyebrow. The cyst had been gradually increasing in size for the past 2 years. On MRI, it showed high internal signals on T1- and T2-weighted images. However, the signal intensity decreased homogeneously in the fat-suppressed T2-weighted images. The observed tumor had a yellowish appearance under the endoscope. On the basis of these findings, the lesion was considered a lipoma until it ruptured intraoperatively. The pathological diagnosis confirmed it to be a dermoid cyst.ConclusionSome dermoid cysts contain lipid-rich liquid, and these may be misdiagnosed as lipomas by MRI. When a tumor is located at a common site for a dermoid cyst, the MRI images should be validated carefully if it appears like a lipoma, and the differential diagnosis should be considered carefully.

Rescue technique for complete removal of an accidentally ruptured orbital dumbbell deep dermoid cyst: A case report.

Project description:PurposeTo report a rescue technique for complete removal of an accidentally ruptured orbital dumbbell deep dermoid cyst.ObservationsA 33-year-old female presented with left proptosis with retrobulbar discomfort for 3 months. Computed tomography images showed an orbital dumbbell deep dermoid cyst. A lateral orbitotomy was performed under general anesthesia. The cyst was ruptured during osteotomy of the lateral orbital rim. The cyst was opened vertically from the ruptured site using a Stephen's tenotomy scissors to visually confirm the internal wall of the cyst and to keep the epithelial lining intact while separating the external wall of the cyst from the bone. There was a small defect of the epithelial lining at the inferoposterior margin of the cyst. Granulomatous inflammation of the lacrimal gland was found adjacent to the defect site. The cyst was completely removed and the lacrimal inflammation subsided after the operation.Conclusions and importanceOpening of the cyst is a useful technique to remove the entire epithelial lining of an accidentally ruptured dumbbell dermoid cyst.
