Malacoplakia: case report in tongue and review of the literature.
(41/123)
Malakoplakia is a relatively uncommon chronic inflammatory reaction of unknown etiology. It usually affects the genitourinary tract but may rarely involve the tongue. There are many theories that explain this reaction but it seems to be the answer to an infectious agent in a patient with immunologic deficiency. Microscopically, malakoplakia is characterized by the presence of foamy histiocytes with distinctive basophilic inclusions, which are known as Michaelis-Gutmann bodies due to a partially ingested bacteria and their posterior calcification. There are many alternatives to treat this entity. We report the only case diagnosed in the tongue, in a 15 years-old male in the Maxillofacial Surgery and Stomatology Service of the Hospital San Vicente de Paul in Medellin, Antioquia, Colombia.

Lingual infarction in Wegener's Granulomatosis: a case report and review of the literature.
(42/123)
Actinomycotic infections are known to be associated with difficulties in making the diagnosis and treatment. Actinomycosis of the tongue is rare and of great importance, not only because it can mimic many other diseases, but also because the tongue itself has some histophysiologic features that make it resistant to infections. In this report, we present a case of lingual actinomycosis and discuss the predisposing factors as well as the diagnostic methods and therapeutic modalities. (+info)
Infected lingual osseous choristoma. Report of a case and review of the literature.
(44/123)
Osseous choristoma is a rare, benign lesion of the oral cavity occurring usually in the tongue. It appears as a tumorous mass of normal bony structure with mature cells in an ectopic position. The case of a 72 years Caucasian male is presented and analyzed along with 52 similar cases reported in the English literature between 1967 and 2007. Lingual choristoma shows a female predilection, whereas the commonest anatomic location is the posterior third of the tongue, occurring at or close to the foramen caecum and the circumvallate papillae. Histologically the lesions show signs of a well-circumscribed mass of vital bone located under the surface oral epithelium. Some lesions represent developmental malformations, whereas others may be reactive lesions after trauma or chronic irritation. Treatment of lingual osseous choristoma consists of simple excision.

White spongy nevus: a nonhereditary presentation.
(45/123)
White spongy nevus (WSN) is a rare hereditary dyskeratotic hyperplasia of the mucous membranes. It is an autosomal dominant disorder with variable penetrance. A few cases of WSN occur due to de novo mutations. We report a case of WSN in a 12-year-old female child, with none of her family members having similar lesions. (+info)

Reduction of micronuclei in oral lichen planus supplemented with beta-carotene.
(48/123)
An elevated frequency of micronucleated exfoliated cells (MEC) in atrophic and erosive oral lichen planus (OLP) has been reported. To evaluate the effects of supplemental beta-carotene (BC) on MEC frequency in OLP lesions, we performed an open trial in 20 patients with atrophic and/or erosive OLP. Each patient received 15 mg of BC four times daily for 3 months. The frequency of MEC in both lesions and adjacent normal mucosa in each patient was evaluated and compared before and after supplementation. Serum levels of BC and retinol were also determined. After BC supplementation, all patients had higher levels of serum BC and retinol. The MEC frequency in OLP lesions was significantly reduced (P < 0.01). No significant changes were seen in the MEC frequency in adjacent normal mucosa. BC supplementation thus significantly reduces MEC frequency in atrophic and erosive OLP. (+info)
