Black esophagus due to acute necrotizing esophagitis. Report of one case Acute esophageal necrosis, which presents as a black esophagus on endoscopy, is an uncommon occurrence. It is defined as a dark pigmentation of the esophagus associated with histologic mucosal necrosis. We report a 75-year-old men who developed black esophagus due to acute esophageal necrosis caused by septicemia. The patient had a favorable evolution (Rev Méd Chile 2009; 137: 672-4).
Purpose: Odontogenic cysts occur in the oral and maxillofacial region; most jaw
cysts are lined by epithelium derived from odontogenic epithelium associated
with tooth development. Odontogenic cysts can be classified as “developmental
type” or “inflammatory type”. A correct diagnosis is essential for planning the
treatment of conditions that compromise the maxilla-mandibular complex. Given
that, a significative number of cystic lesions of the jaws share similar clinical and
radiographic features, the diagnosis of odontogenic cysts, usually requires detailed
analysis of the clinical, radiological and histopathological findings. All odontogenic
cysts, with the exception of inflammatory periapical cyst and lateral radicular cyst,
should be treated with surgical intervention. The periapical cystic lesions are usually
treated by conservative endodontic treatment (periapical curettage) or surgical
treatment (enucleation, marsupialization and decompression). In lateral radicular and
inflammatory periapical cysts, surgery is indicated only if the lesions do not regress
after removal of odontogenic infection intra-canal the affected tooth. In case of
residual cyst, surgery is the only option.
Case Report: A 55-year-old female patient, caucasian, attended the Oral-Maxillofacial
Surgery consultation at Clitrofa - Centro Médico, Dentário e Cirúrgico, in Trofa - Portugal,
to evaluate a dental cyst in the second quadrant diagnosed during the evaluation to
place dental implants in the upper jaw. It was decided to carry out surgical treatment
of the lesion using LightWalker® from Fotona with application of Er:YAG and Nd:YAG
lasers.
Conclusion: After a 12-month follow-up period, the patient is pain free and the lesion
has no signs of recurrence. Laser therapy may be considered a successful treatment
modality for inflammatory odontogenic cyst
