Glandulaer odontogen cyste. Niårs klinisk og radiologisk opfölgning
Sammanfattning
Background - Glandular odontogenic cysts are rare intrabony
cysts, with a preferred site in the anterior part of the mandible.
The cyst occurs mostly between the ages of 40 and 60 with no
significant difference between the sexes. The glandular odontogenic
cyst often presents as an asymptomatic and slow growing
swelling and radiographically it appears as either a uni- or multiloculated
welldefined radiolucency. Treatment of the cyst is surgical
extirpation, but since GOC has a more aggressive growth
pattern and higher recurrence rate, histological correct diagnosis
is of importance in a long-term follow-up programme.
Case study - A sixteen-year-old boy was referred to the Department
of Oral and Maxillofacial Surgery, Aalborg University Hospital,
for diagnosis and treatment of a cyst in relation to an impacted
canine in the upper jaw. The patient was treated with surgical
enucleating of the cyst and concomitant removal of the impacted
tooth. Histological examination revealed the diagnosis glandular
odontogenic cyst. At 9 years follow-up, the patient showed no
sign of recurrence.
Conclusion - Odontogenic cysts are common and generally
with a low recurrence frequency. However, glandular odontogenic
cysts have an aggressive behaviour and high rate of recurrence
and histological examination and diagnosis is important for the
right follow-up programme.
