Coexistence of dermal sinus tract, dermoid cyst, and encephalocele in a patient presenting with nasal cellulitis Case report
ABSTRACT Dermoid cysts, encephaloceles, and dermal sinus tracts represent abnormalities that develop during the process of embryogenesis. The elucidation of the precise timing of formation for these malformations has remained elusive at the molecular level of study. Yet, clinical experience has demonstrated that these malformations do not all occur in the same patient, suggesting a shared pathway that goes awry at distinct points for different patients, resulting in 1 of the 3 malformations. Herein the authors describe a case in which all 3 malformations were present in a single patient. This is the first description in the English literature of a sincipital encephalocele occurring with a dermoid cyst and a dermal sinus tract.

ABSTRACT: E ctopic cilia are extremely rare congenital anomalies in which eyelash follicles appear in an abnormal place on the eyelid, most typically on the lateral quadrant of the anterior surface of the upper eyelid. There is usually no associated medical comorbidity with this anomaly. In the majority of cases, simple surgical excision is indicated because of its cosmetic aspect. We present a case of a patient with ectopic cilia and associated dermoid cyst with sinus tract in which no clinical signs of a possible presence of orbital pathology were present at the time of the diagnosis. This case report highlights the value of radiological examination prior to surgical excision of ec-topic cilia to discover this rare finding. case report History and Examination A 3-year-old boy presented to the Department of Oph-thalmology with a cluster of dark hairs on the lateral quadrant of the anterior surface of his left upper eyelid (Fig. 1). There was no history of inflammation or swelling of the eyelid and his medical history was unremarkable. No positive family history of any eye abnormalities was noted. An ophthalmological examination revealed 1 mm of ptosis, with the remainder of the examination showing normal results. No proptosis, inferior displacement, or palpable orbit-al mass was present. His general physical examination wasJournal of Neurosurgery Pediatrics 05/2015; DOI:10.3171/2014.12.PEDS14512 · 1.37 Impact Factor
