“…Nevertheless, CT scan and magnetic resonance imaging (MRI) are considered the best diagnostic exams to confirm the extracranial position of the cyst 16,17 . Encephalocele, meningocele, hemangioma, lipoma, cephalohematoma, sebaceous cyst, pilonidal cyst and sinus pericranii are important pathologies to the differential diagnosis of this lesion [18][19][20][21] . There is no report on neurological alterations nor on the recurrence of the pathology.…”

-Head and neck dermoid cysts are lesions relatively rare, which usually occur during childhood as solitary lesions. They are often identified and surgically removed at birth, being uncommon in adults. A 23-year-old male presented with a congenital tumor of the anterior fontanelle, which histopathological examination revealed a dermoid cyst. Surgical intervention is the treatment of choice to remove this lesion. The objective of this study is to report the case, once this type of lesion is rare in adults.KEY WORDS: dermoid cyst, epidermoid cyst, anterior fontanelle, adult.Cisto dermóide na fontanela anterior de adulto: relato de caso RESUMO -Cistos dermóides de cabeça e pescoço são relativamente raros e, usualmente, ocorrem na infân-cia como lesões solitárias. Eles são diagnosticados e operados ao nascer, na maioria dos casos; portanto, essa é uma lesão incomum no adulto. Um homem de 23 anos apresentava tumoração congênita na fontanela anterior, cujo exame histopatológico revelou ser cisto dermóide. Foi submetido a tratamento cirúrgico. O objetivo desse estudo é relatar o caso, uma vez tratar-se de condição rara no adulto. PALAVRAS-CHAVE: cisto dermóide, cisto epidermóide, fontanela anterior, adulto.Head and neck dermoid cysts are relatively rare, and usually occur during childhood as solitary lesions 1 . The cysts over the anterior fontanelle represent about 0.1% of all skull tumors and they are identified and surgically removed at an early age. Therefore, this pathology is rarely observed in adulthood. In order to correctly identify these lesions, diagnostic imaging such as simple X-rays and computer tomography (CT) scan are necessary, besides physical evaluation 2 .We report a case of dermoid cyst over the anterior fontanelle in an adult patient. CASEA 23-year-old man seeked medical help at the Neurology department of Instituto Doutor Jose Frota hospital with a mass over the anterior fontanelle, diagnosed as congenital, which increased in size over the years since the birth (Fig 1). The patient did not show neurological symptoms. The CT scan of the skull demonstrated extracranial lesion with cystical appearance, without intracranial communication (Fig 2). During the excision of the lesion, it was observed a cyst containing a viscous, odorless, and greencolored liquid, with hair (Fig 3). The bacterioscopy of this liquid was negative. The cyst was removed together with its walls, the excess of scalp was ressected, and the skull was properly covered with the patient's skin maintaining the natural hair line. A skull depression underneath the lesion could be observed. A drain with continuous suction was positioned and removed after two days containing a serum-bloody secretion. The histopathological exam of the lesion revealed dermoid cyst. There were no surgical intercurrencies, and the patient recovered without complaints and very satisfacted with the functional and aesthetical results.

RESUMO PALAVRAS-CHAVECisto dermóide. Cisto de inclusão congênita. ABSTRACT Congenital dermoid inclusion cyst of the anterior fontanel. Report of two cases The congenital dermoid inclusion cyst of the anterior fontanel is a benign tumor which has rarely been described. The authors report two cases of congenital dermoid inclusion cyst of the anterior fontanel in children (7 year-old and 3 month-old). The pathology, differential diagnosis, computed tomography, X-ray findings and the treatment are discussed. KEYWORDS Congenital inclusion cyst. Dermoid cysts. IntroduçãoOs cistos dermóides de inclusão congênita (CDIC), situados no espaço subgaleal, são considerados como tumores decorrentes de defeitos do desenvolvimento embriológico, durante o fechamento do sulco neural entre a terceira e a quinta semanas da gestação, ocasião em que a pele pode ser inserida dentro do osso ou do tecido mole, em um interespaço ósseo como o da fontanela anterior 3,6,12,20,22,23 . Os autores apresentam dois casos de CDIC situados na fontanela anterior em uma criança com 7 anos e outra com 7 meses. Foram diagnosticados por exames físicos e radiológicos. O tratamento indicado foi a extirpação total e o diagnóstico foi confirmado histopatologicamente. Discute-se o diagnóstico diferencial, os exames complementares, a conduta e o prognóstico.

Refere a genitora que o menor nasceu de parto normal e, aos 4 meses, notou a presença de uma tumoração na cabeça, que vinha crescendo progressivamente de tamanho. Procurou, nesta ocasião, um pediatra que lhe informou ser um processo benigno e que não era necessário tratamento específico no momento. Aos 7 anos, a genitora achou que a referida tumoração estava grande e prejudicando o menor no ato de pentear os cabelos; assim, procurou serviço especializado para seu tratamento e encaminhado ao Ambulatório de Neurocirurgia do CCBS-UFS, com diagnóstico de cisto sebáceo na fontanela anterior.

-Congenital dermoid inclusion cyst over the anterior fontanel (CDIC) is an uncommon cystic lesion located over the anterior fontanel. It is a benign and curative lesion and most of the time, can be diagnosed at birth. From 1994 to 2001, three patients were operated with this kind of lesion and after reviewing the literature we found 229 cases and only 6 cases described in Brazil. Our objective in this study is to report three more cases.KEY WORDS: congenital inclusion, dermoid cyst, epidermoid cyst, anterior fontanel.Cisto dermóide de inclusão congênita sobre a fontanela anterior: relato de três casos Cisto dermóide de inclusão congênita sobre a fontanela anterior: relato de três casos Cisto dermóide de inclusão congênita sobre a fontanela anterior: relato de três casos Cisto dermóide de inclusão congênita sobre a fontanela anterior: relato de três casos Cisto dermóide de inclusão congênita sobre a fontanela anterior: relato de três casos RESUMO -Cisto dermóide de inclusão congênita sobre a fontanela anterior (CDIC) é lesão rara localizada na região da fontanela anterior. Trata-se de lesão benigna e curável que, na maioria das vezes, é diagnosticada no nascimento. De 1994 a 2001, três pacientes foram operados com este tipo de lesão e, através dos dados disponíveis na literatura, verificamos somente 229 casos descritos, apenas 6 descritos no Brasil, o que nos motivou a registrar mais três casos. PALAVRAS-CHAVE: inclusão congênita, cisto dermóide, cisto epidermóide, fontanela anterior. Many different types of lesions over the children's skull exist and some are commonly diagnosed in daily practice. Congenital dermoid inclusion cyst over the anterior fontanel (CDIC) is a rare and benign lesion located over the anterior fontanel. Many children are examinated with lesions over the skull in our hospital. In a recent review of these children, our attention was drawn to three patients with a cystic rounded mass over the anterior fontanel. These three patients showed no neurological abnormality and the diagnosis of CDIC were confirmed by surgery and histological examination. Our literature search found 229 other cases (Table 1) of CDIC worldwide. CASESFrom 1994 to 2001, three patients were operated with a cystic mass over the anterior fontanel, being of different ages and without neurological abnormality at the time. The first patient a three-year-old-white boy. The second patient (Fig 1) a five-month-old-black girl and the third patient (Fig 2) a five-month-old-white boy. All patients were treated with surgery and using the same approach for each of them (Figs 3 to 12 -the second patient shows all the surgical steps, for better illustration). All three patients presented in this paper are similar in all aspects when compared to those in other papers. Two patients were reviewed recently. The first patient (Fig 13 -no photograph prior to surgery) has a learning disability but is not due to the cyst. He was noted to have a small lipoma over the callosal body. The recent photograph shows the cyst has not recurred. ...
