Bilateral Frontozygomatic Dermoid Cysts

Complex presentation of a left Fronto-zygomatic Dermoid cyst; a case report

We present a case of craniofacial dermoid cyst in a 50-year-old female. The patient's complaint was persistent refractory headaches with no other significant neurological symptoms. Diagnostic imaging revealed the presence of a lesion in the left fronto-zygomatic region. Surgical intervention involved a craniotomy that led to a successful excision of the dermoid cyst. The diagnosis was subsequently confirmed by histopathological analysis. This case underscored the importance of considering DC as a potential diagnosis for any craniofacial lesion, given their diverse presentations and associated complications.

Bilateral orbital dermoid cysts: A case report

Dermoid cysts are one of the most common benign orbital tumours in children and usually occur unilaterally. Bilateral dermoid cysts in the orbit are rare. We report here, a case of bilateral orbital dermoid cysts, in a 29-month-old baby girl. The patient's prognosis was favourable following surgical resection. Through this case report, we hope to increase the recognition and understanding of this condition.

Bilateral lambdoid dermoid cyst

Generally, dermoid and epidermoid cysts arise as a result of incomplete separation of the neuroectoderm from the superficial ectoderm with displacement of ectodermal elements along their lines of fusion during development. Dermoid cysts of the posterior head are rare lesions composed of epidermal and mesodermal elements. Furthermore, dermoid cysts in the occipital area are extremely rare. The presence of synchronous, bilateral occipital dermoids is quite rare and has not been reported previously. A unique case of lambdoidal dermoids in a 75-year-old woman is presented. Large right lesion was excised concurrently through direct skin incision, and a very small left mass was observed. And the etiology, natural history, management, and prognosis of dermoids are reviewed.

Midline dermoid cyst resulting in frontal bone erosion

A dermoid cyst is a thin-walled benign tumor formed by the entrapment of ectodermal tissue during embryologic development, resulting in the inclusion of epithelium and adnexal elements within the tumor. Dermoids are not unique to a single anatomic location but are often isolated to the skin and subcutaneous tissue. They may occur intracranially or intra-abdominally, oftentimes associated with the ovary. If presenting as a midline mass of the skull, preoperative imaging with computed tomography and/or magnetic resonance imaging is necessary to evaluate for possible intracranial extension, given the altered embryologic development behind the formation of these cysts. Differential diagnosis of a midline frontonasal mass includes epidermoid or dermoid cyst, encephalocele, glioma, and sinus pericranii. The management of suspected dermoid cysts includes complete surgical excision, which may require a combined intracranial and extracranial approach. We present a 2-year-old boy who presented to our institution with a congenital midline scalp mass separate from the anterior fontanelle with complete underlying bony erosion to the sagittal sinus demonstrated on preoperative imaging, who required early surgical excision and reconstruction of the bony defect.

Giant dermoid cyst of the lower limb: presentation of a rare case

BACKGROUND

Dermoid cysts are unusual neoplasms that often present in childhood and are usually located in the head and neck region.

OBJECTIVE AND METHOD

We describe a rare case of a giant dermoid cyst of congenital inclusion type located at the lower extremity of a young male. Preoperative imaging studies were performed for evaluation of the mass.

RESULT

The cyst was surgically removed, and histopathologic examination confirmed the diagnosis.

CONCLUSION

Dermoid cysts rarely appear in the lower extremity and must be included in the differential diagnosis of cystic lesions of the lower limb.

Current trends in the surgical management of orbital dermoid cysts among pediatric ophthalmologists

PURPOSE

To survey the membership of the American Association for Pediatric Ophthalmology and Strabismus on their preferences in the management of dermoid cysts.

METHODS

The 689 active members of the American Association for Pediatric Ophthalmology and Strabismus were surveyed by mail on their preferences in the management of dermoid cysts. The survey addressed use of imaging, timing of surgery, surgical approach, use of corticosteroids, and satisfaction with results.

RESULTS

Of the 689 members surveyed, 62.4% responded. Of these, 75.8% performed orbital dermoid excisions in their pediatric ophthalmology practices. Imaging was always obtained by 9.5%, never obtained by 9.5%, and obtained for specific reasons by 81.0%. Computed tomography scan was the preferred imaging modality of 66.2% of respondents. Surgery was deferred until older than 6 months by 68.9%, and 71.9% cited anesthetic risk as the reason for waiting. Surgical approaches used were sub-brow incision only (53.9%), eyelid crease incision only (15.8%), or either (22.6%). Ninety-six percent of respondents never used adjunct corticosteroids, and 99.2% of respondents were satisfied with their surgical results.

CONCLUSIONS

The majority of American Association for Pediatric Ophthalmology and Strabismus members defer orbital dermoid surgery until 6 months of age due to anesthesia risk, use the sub-brow incision, and obtain imaging only for specific reasons. Most respondents never use systemic corticosteroids at the time of surgery, and are satisfied with their results.
