Grave’s disease in a case of Goldenhar syndrome

Goldenhar syndrome (GS) is a malformation complex that involves structures arising from the first and second branchial arches. Graves’ disease is an autoimmune disorder resulting in the excessive production of thyroid hormones and is the most common cause of hyperthyroidism in children. We are reporting this case since the clinical association of Graves’ disease in GS has never been reported before and is a rare association of the syndrome. An 11-year-old developmentally normal child presented to us with swelling in front of her neck for the past 6 months associated with loss of weight, increased appetite, increased frequency of defecation, and palpitations. On examination, there was diffuse swelling in the thyroid region that moved with deglutition and did not move with protrusion of the tongue. The child also had an asymmetrical face with bilateral conjunctival dermoid and bilateral preauricular skin tag and pretragal sinus tract on the left side. Hence, a provisional diagnosis of goitre with features of hyperthyroidism in a child with first and second branchial arch syndrome was considered. Technetium 99 scan confirmed diagnosis of Graves’ disease. The child was started on carbimazole and propranolol and gradual improvement in symptoms noted. Propranolol was given for 3 months until symptoms such as palpitations and anxiety subsided and then stopped. Carbimazole was continued.

Unusual presentation of conjunctivo-palpebral dermoid

A 10-year-old girl child presented with a chronic history of redness and itching in her right eye. Slit-lamp examination revealed two small reddish flat masses with few caterpillar hair-like structures in the lower palpebral tarsal conjunctiva simulating ophthalmia nodosa. However, histopathology of the excised mass showed a lesion composed of stratified squamous epithelium with hair follicles and adnexal tissues embedded in fibro collagenous substance compatible with dermoid choristoma. Different types of choristoma in bulbar conjunctiva, eyelid, and orbit have been mentioned in earlier literature. Palpebral conjunctival dermoid choristoma has been rarely described previously and the current case is a unique presentation of that entity.

Ocular dermoids and microphthalmia in a juvenile sheep

A 6-month-old Leine sheep was presented because of dermal tissue located on the left eye. During the first examination, the animal was clinically silent, apart from the deformed eye. A corneal and conjunctival dermoid and blindness of the left eye were diagnosed. Over a period of a year, the animal displayed conjunctivitis and inflammation of the affected eye. Furthermore, the sheep did not develop according to its age. During histopathological examination of the euthanized animal, microphthalmia and aphakia of the left eye were found in addition to the dermoids. Dermoids are described in humans and in different domestic animals. They can be combined with other congenital malformations. In sheep, dermoids are rarely diagnosed or reported in the literature.

Belçika Malinois Irkı Bir Köpekte Konjuktival Dermoid

Summary In this report, the gross and histopathological findings and the surgical treatment of a rarely seen case conjunctival dermoid was described in Belgian Malinois dog. A 6 month-old female Belgian Malinois dog, weighing 8 kg was referred to the University animal hospital with the complaint an abnormal mass on the right eye. In ophthalmic examination of right eye, epiphora and conjunctival hyperaemia were observed. Mass in the right conjunctiva at the temporal canthus was surgically removed. In microscopic examination, resected tissue revealed that dermoid was originated from conjunctiva.

Recurrent Conjunctival Dermoid Cyst With Reactive Lymphoid Hyperplasia

Conjunctival dermoid cysts are a rare subtype of dermoid cyst usually presenting in adulthood. The authors report a case of a recurrent conjunctival dermoid cyst with reactive lymphoid hyperplasia that was immunohistochemically demonstrated to be polyclonal. Follicular centers that were present within the cyst wall were negative for Bcl-2 and positive for the immunohistochemical markers CD20, Bcl-6, CD10, and Ki67, which helped to differentiate the lesion from a follicular lymphoma. The lesion did not recur after 14 months of follow-up.

A Case of Conjunctival Dermoid Cyst of the Orbit

Purpose: To report a case of primary conjunctival dermoid of the superonasal orbit. Case summary: A 41-year-old man complained of swelling of the left lower eyelid and left periocular pain for a week. Examination revealed 3 mm of proptosis with superotemporal displacement of the left eye. Orbital CT revealed a 322733-mm well-defined giant cyst with a fat-fluid level in the superonasal aspect of the left orbit. Orbital MRI showed bone remodeling around the cyst, consistent with a dermoid cyst. The cyst was approached via lateral orbitotomy and transcaruncular incision but was ruptured just prior to the end of the dissection and was totally excised using a cryoprobe to freeze the ruptured site. Upon histopathological examination, the cyst was misdiagnosed as a conjunctival cyst because there was no dermal appendage but was rediagnosed as a conjunctival dermoid cyst after the tissue sample was examined more thoroughly. After surgery, the patient presented with diplopia due to esodeviation and was prescribed prismatic lenses.

Orbital Conjunctival Dermoid Cyst With Oncocytic Differentiation

A dermoid cyst of conjunctival origin ("conjunctivoid") is a rare variant that has conjunctival nonkeratinizing squamous epithelium and goblet cells, instead of keratinizing squamous epithelium of epidermal origin with epidermal appendages. We report a case of a 65-year-old man with a chronic orbital mass, a conjunctival dermoid that was found to have the unusual histopathologic finding of oncocytic differentiation. This is an infrequent benign chronic change in glandular cells characterized by the accumulation of vast numbers of intracellular mitochondria. Occasionally, oncocytic cellular change occurs in malignant tumors, and so complete excision of such lesions is recommended.

Congenital Ocular Dermoid Cyst in a River Buffalo (Bubalus bubalis) Calf

Clinical and histopathological findings of a congenital ocular dermoid cyst, located at the lower eyelid of a river female buffalo (Bubalus bubalis) calf were presented. A soft, fluctuant, non-tender, hyperaemic cystic mass was detected overlaying the left eye. Fine needle aspirate revealed filamentous debris with no malignant cells. The cyst was treated surgically by orbital exenteration and subsequently subjected to histopathological examination. The histopathological study disclosed a conjunctival dermoid cyst. This report is novel, in that; such ocular cyst has not previously been described in river buffalo calves.

Dermoid Cyst of Conjunctival Origin

A 22-year-old man with a recurrent intraconal cystic mass of the orbit presented with proptosis, motility restriction, and optic disc edema. On initial surgery, the cyst wall showed nonkeratinized cuboidal epithelium with adnexal structures. After recurrence, repeat histopathologic evaluation again showed nonkeratinizing conjunctival epithelium with goblet cells. The diagnosis was consistent with a dermoid cyst of conjunctival origin. Our review of the literature found 29 previous cases in the literature. Unlike typical cutaneous dermoids, conjunctival dermoids occur in young adults and are usually located in the nasal or superonasal deep orbit. The location and adnexal structures associated with these lesions suggests derivation from embryonic epithelium destined to become caruncle.

Ocular dermoids in cattle

A 2-week-old calf in the USA was presented because of severe ocular irritation; examination revealed a large conjunctival dermoid. A conjunctivectomy was curative, as evidenced by no recurrence with a 4-month follow up. A review was compiled from the literature and the Veterinary Medical Database. Dermoids have been reported in 22 breeds of cattle, with the Hereford being overrepresented. Average age at presentation is 6.1 months. Calves usually show signs of severe ocular irritation, which is caused by hair on the surface of the dermoid. Dermoids may occur on the cornea, limbus or conjunctiva. Surgical excision via keratectomy or conjunctivectomy after sedation with xylazine and local anaesthesia is curative in most cases.

Anesthetic Experience in a Patient with Goldenhar Syndrome: A case report

Goldenhar syndrome is a rare congenital disorder of hemicraniofacial and vertebral defects related to the abnormal development of the first and second branchial arches. In some infants, congenital heart disease, and pulmonary and renal defects are also present. Goldenhar syndrome commonly involves an airway which is difficult to manage. Tracheal intubation may be difficult due to a combination of retrognathia, micrognathia, mandibular hypoplasia, palatal defects and vertebral abnormities. We experienced the anesthetic management of an 8-month-old boy with Goldenhar syndrome who received excision and biopsy for conjunctival dermoid and ureteral reimplantation for vesicoureteral reflux under general anesthesia. Airway management, with thiopental, rocuronium and sevoflurane, and tracheal intubation were accomplished successfully in the patient. Surgery was performed uneventfully and the patient was discharged without complication.

Conjunctival cyst and conjunctival dermoid of the orbit

BACKGROUND . Conjunctival dermoids and conjunctival cysts of the orbit were first reported by Jakobiec et al. in 1978. Communications regarding this type of cysts have been sporadic. PATIENTS AND METHODS . We describe the clinical and histopathologic findings in two patients with histopathologically confirmed conjunctival dermoid and conjunctival cyst of the orbit. A review of the literature was also carried out. RESULTS . A 27-year-old female presented with a slowly growing tumor in her left orbit inferomedially. Histopathologically, the tumor was a conjunctival cyst. A 20-year-old male was seen with a painless, slowly-growing mass in his right orbit nasally. The histopathologic study disclosed a conjunctival dermoid. Echography was useful in both cases in demonstrating the cystic structure of the tumors. Conjunctival dermoids and cysts are usually noticed in adulthood, are located nasally or superonasally, lack an associated osseous defect and are lined by a non-keratinizing epithelium with goblet cells. CONCLUSION . Conjunctival dermoids and cysts of the orbit display clinical, radiologic and histopathologic features that differentiate them from the more common dermoid cysts. Emphasis must be given to these distinctive features, since these lesions have probably been largely misdiagnosed.
