RESUMEN
This report demonstrates the association between the development of a nasopalatine duct cyst and implant surgery, involving 2 implants positioned 4 years after teeth extraction at a site unaffected by any prior local endodontic disease or radiolucency. The cyst was removed and the residual void was filled with deproteinized bovine bone. Two-year follow-up showed no cyst recurrence, the normal anatomy was partly restored, and one of the implants showed clinical signs of re-osseointegration.

OBJECTIVE: The aim of this study is to characterize immunohistochemical profiles of lining epithelia of nasopalatine duct cyst (NPC) as well as to correlate those findings with their clinicopathological features to understand the histopathogenesis of NPC. MATERIALS AND METHODS: Forty-one surgical specimens from NPC were examined for clinical profiles and expression of keratin-7, 13, MUC-1, and P63 by immunohistochemistry, compared to radicular cyst (RC) and maxillary sinusitis. RESULTS: Nasopalatine duct cyst was clinically characterized by male predominant occurrence: 44% of the cases involved tooth roots, and 70% with inflammatory backgrounds. Lining epithelia of NPCs without daughter cysts were immunohistochemically distinguished into three layers: a keratin 7-positive (+) ciliated cell layer in the surface, a keratin-13+ middle layer, and a MUC-1+/P63+ lower half, indicating that they were not respiratory epithelia, and the same layering pattern was observed in RC. However, those immunolocalization patterns of the main cyst lining with daughter cyst were exactly the same as those of daughter cyst linings as well as duct epithelia of mucous glands. CONCLUSIONS: Two possible histopathogenesis of NPC were clarified: one was inflammatory cyst like RC and the other was salivary duct cyst-like mucocele.

The authors report a cystic lesion within a previous unilateral cleft lip and alveolus bone graft site in a 15-year-old girl, 5 years after the secondary bone graft. The cyst comprised respiratory epithelial lining, which is thought to be a remnant of the nasal mucosal lining of the primary cleft.

Globulomaxillary cysts are located in the globular and maxillary process fusion area; they are not of odontogenic origin. Their etiology is similar to oral and facial clefts, which explains why they are classified as ontogenic fissural cysts. However, some clefts are not localized precisely on the premaxillary and maxillary process fusion area and their etiology as globulomaxillary cysts is questioned. In fact, those lesions could actually be of odontogenic origin.

Nasolabial cysts are rare non-odontogenic cysts that occur beneath the ala nasi, and debate about their complicated, unique pathogenesis continues. It is widely accepted that these lesions originate from the anlage of the nasolacrimal duct; however, some still think that nasolabial cysts arise from fissural cysts. The authors report a patient with a nasolabial cyst who also had a unilateral cleft lip and palate. This unusual finding may indicate a different origin for nasolabial cysts than what has been accepted in the past.

Los quistes nasolabiales son clasificados como no odontogénicos y son los únicos quistes de este grupo que ocurren en los tejidos blandos (localización extraosea). Esta condición está reconocida y documentada en la literatura. La revisión de la misma confirma que esta lesión quística es de desarrollo benigno y comienza en el epitelio del ducto nasolagrimal. El propósito de esta presentación consiste en documentar el caso clínico de un paciente que presentaba esta patología.(AU)

Nasolabial cysts are rare but easily identifiable when they do occur. They are thought to arise from the remnants of the nasolacrimal ducts, but most of the available information on these cysts is limited to isolated case reports. The purpose of our study was to examine the clinical and pathologic features of nasolabial cysts in order to provide a basis for their correct diagnosis and treatment. Eighteen patients with nasolabial cysts were treated at Korea University's Guro Hospital between Jan. 1, 1988, and Dec. 31, 1999. We retrospectively analyzed the clinical appearance, pathologic findings, and treatment results in each case. All patients underwent surgery via the sublabial approach. The lining epithelia were identified as either pseudostratified, stratified squamous, or simple cuboidal. A cyst recurred in only one case, and there were no surgical complications on follow-up. The results of our study provide a basis for sound diagnosis and treatment.

A case of nonspecific cystic degeneration complicating fibrous dysplasia of the mandible is presented. This condition is extremely rare in the jaw bones. The patient had a painless swelling of the right face measuring 10 cm in diameter, and there was no history of trauma. Radiographs showed a poorly defined, "ground glass" radiopaque lesion; a central well-defined cyst was confirmed by means of computed tomography. During surgery, a large cystic cavity with surrounding, soft fibrous bone that merged with the cortex was observed. Histologic examination showed a large non-epithelial-lined cystic cavity with a surrounding fibro-osseous lesion, which was consistent with a diagnosis of fibrous dysplasia.

The number and variety of cysts that occur in the jaws are greater than those in any other part of the body. Consequently, dental practitioners must keep up with advances in this field, including the definition of new entities, such as the glandular odontogenic cyst; the deletion of the old incorrect concept of maxillofacial fissural cysts, including the globulo-maxillary cyst; and the advances in the molecular biology of established cysts, such as the dentigerous cyst and the odontogenic keratocyst.

Globulomaxillary cyst is a non odontogenic cyst arising in the upper lateral incisor and canine region. Evaluation of clinical picture and careful histologic examination are essential for distinguishing it from other odontogenic and non odontogenic cystic growths. Presenting five new cases of globulomaxillary cysts, authors discuss and accept the "fissural" histogenetic hypothesis.
