Sir,

Dermoid cysts that anterior fontanel in adults space rare. These space benign cystic lesions that happen at present of fusion in the body. Dermoid cysts the the scalp including at the anterior fontanel in infants and little children have been reported in the literature.<1,2,3> yet not plenty of reports exist ~ above this condition in adults. Here, we existing three adults that presented v this condition. The an initial patient to be a 27-year-old young guy who i found it this swelling around 7 years before. He i found it this once he started getting hurt while wicker his hair. Clinical examination

revealed a well-rounded ede of about 3 cm × 3 cm dimension in the region of the anterior fontanel. There to be no visible pulsations, any type of sinus tract or punctum or dilated veins seen. ~ above examination, the lesion had actually heterogeneous consistency with some locations soft and cystic. It to be nontender and nonpulsatile and also did not give a cough impulse. Transillumination was not present and there was no bruit ~ above auscultation. The bony margins were felt to be inverted. The next patient was an 18-year-old boy that underwent tonsuring that the head and also noticed the swelling of roughly 1.5 cm through a punctum. The various other findings were similar. There was no discharge indigenous the punctum. In this 22-year-old young female, the beautician noticed this ede with similar findings however no punctum. Every the patient underwent computed tomography (CT) scans which verified no intracranial expansion in any type of case. Magnetic resonance imaging (MRI) was done in every cases and intracranial extensions were ruled out. All the patients underwent total excision the the lesion. During surgery, the lesions had actually hair and also calcified portions and also one that the swellings proved rudimentary teeth. Over there was part erosion of the outer table in one situation (the young man), however there was no breach of the within table in any kind of of the cases. The histopathological report in all situations was dermoid cyst. Dermoid cysts in the head and also neck are usually thought about congenital lesions. However, occasionally, this lesions have actually been established in adults also. The importance of dermoids in the scalp is the potential because that intracranial extension. Here, we explain three adults through histologically showed dermoid cysts in the anterior fontanel an ar without any kind of intracranial extension.

de Carvalho et al.<3> presented 7 patients age 3 months to 16 years v cystic lesions of the anterior fontanel. They were detected in ~ birth and were steady in size however asymptomatic. Every patients underwent removed of the lesion. Ojikutu and also Mordi<2> explained congenital consist of dermoid cysts end the region of the anterior fontanel in 2 adult Nigerians. Both were checked out at birth however were not treated till adult life. There to be no intracranial expansion in both. Histopathologically, both were shown as dermoid cysts. Operation excision was curative. De Castro et al.<4> also presented a 23-year-old guy with a scalp ede at the region of the anterior fontanel without any type of neurological issues. CT scan did no show any type of intracranial extension. The lesion was excised in full with very an excellent result. The lesion to be soft cystic comprise a greenish viscous liquid through hair. Chaudhari et al.<5> described 21 children with congenital inclusion cysts the the subgaleal space. A majority of them were in the anterior fontanel. The cysts were reported together dermoid/epidermoid cysts. There have been numerous other researches on dermoids<6,7> end the anterior fontanel with similar conclusions. Reissis et al.<8> studied the histology the 16 craniofacial cysts and also concluded the histological properties of dermoid cysts are conserved between craniofacial website (periorbital, nasal, scalp, and also postauricular). This reflects the consistency the ectodermal inclusion during early embryological development, i m sorry is elevation of certain craniofacial website or neighboring anatomical structures.

In our study also, all the patients had actually neurologically asymptomatic lesions without any intracranial extension. Every the lesions were confirmed to it is in dermoids histopathologically. Every the lesions to be excised totally without problems. The prominence of these lesions because that the operated doctor is that these can mimic other pathologies such as encephalocoels or meningocoels, and so, CT scan/MRI is a should to ascendancy out the pathology and also any intracranial extension before any kind of surgical intervention. The existence of this entity is especially beneficial for the trainee surgeons and also neurosurgeons.
