Congenital inclusion cyst of the subgaleal space: a case report.

BACKGROUND

Subgaleal cysts are epidermal cysts located under the galea aponeurotica. They are rare lesions but are commoner among the children of African descent. To the authors knowledge, none has been described in Kano, Northwestern, Nigeria.

METHODS

We present the management of a 6 month old Nigerian boy with scalp swelling.

RESULT

The scalp swelling was noticed soon after birth and was progressively increasing in size. There was no preceding fever or trauma to the scalp and no associated pain. At six months, the child could sit without support and had attained adequate neck control. Examination revealed a swelling over the anterior fontanelle, measuring 3x2cm. The swelling was hemispherical, firm, fluctuant, and non-tender. It was not pulsatile. Its size did not increase on crying. Diagnosis was confirmed by plain x-ray film and transfontanelle sonography. Total excision of the mass was carried out under general anesthesia and histology confirmed the diagnosis of epidermal inclusion cyst. The child was discharged home in good condition.

CONCLUSION

Awareness of this lesion will avoid misdiagnosis and inappropriate treatment.
