Glandular odontogenic cyst of the anterior mandible.

Context: Glandular odontogenic cyst (GOC) is a rare cyst occurring in the middle-age people with mandibular anterior as the common site of occurrence.

Case Report: We report a case of massive GOC in a 65-year-old female with an emphasis on its clinical course, histological features, and treatment modalities.

Conclusion: The aggressiveness and recurrences of GOC warrants clinicians for the careful examination, treatment, and long-term follow-up.

Computer assisted histomorphologic comparision and the expression of AgNORs in the central and peripheral giant cell lesions of the oral cavity and giant cell tumor of the long bone.

Objective: Computer-assisted image analysis was attempted to ascertain, if any of the previously described histologic features along with argyrophilic nucleolar organizer regions (AgNORs) could be used to determine the aggressiveness of the central giant cell granuloma of the jaws (CGCG), peripheral giant cell granuloma of the oral cavity (PGCG) and giant cell tumor of the long bones (GCT).

Study Design: The study consisted of 20 cases of CGCG, 20 cases of PGCG and 5 cases of GCT. The histological features included were number of giant cells, number of nuclei in each giant cell, number of blood vessels, fractional surface area (FSA) and relative size index (RSI) of giant cells.

Transcatheter device closure of patent ductus arteriosus without arterial access--single institution experience.

Objective: Retrospective analysis of feasibility, safety and advantages of device closure of patent ductus arteriosus (PDA) using only venous access.

Background: Arterial access for transcatheter device closure of PDA has been a standard practice, but has inherent complications, especially in infants.

Method: Records of patients who underwent PDA device closure from 2004 to 2012 were reviewed.

Odontogenic myxoma: Report of two cases.

Odontogenic tumors represents a broad spectrum of lesions ranging from benign to malignant to dental hamartomas all arising from odontogenic residues, that is, the odontogenic epithelium, ectomesenchyme with variable amounts of dental hard tissues formed in the same sequence as in normal tooth development. We report two cases of myxoma, which were misdiagnosed initially and latter, reported as odontogenic myxoma; and were treated by conservative surgical excision in one case and radical resection with hemimandibulectomy in the other case.
