1/15. Squamous cell carcinoma and keratoacanthoma of the lower lip associated with "Goza" and "Shisha" smoking.BACKGROUND: A positive correlation between lip and buccal cancers and pipe smoking has been suggested. Various types of crude and manufactured tobacco products are consumed by smoking, chewing, and snuff dipping habits. 'Shisha" and 'Goza' smoking are widely practiced in the middle east. The 'hubble-bubble' method and apparatus are used. These smoking habits are hazardous to health, causing obstructive lung disease, and may be important predisposing factors for the development of oral cancers. case reports: Two cases of squamous cell carcinoma and a case of keratoacanthoma localized to the lower lip are presented in well-known 'Shisha' and 'Goza" smokers. CONCLUSIONS: "Shisha" and 'Goza' smoking have adverse effects on general health and may predispose to oral cancer. An extensive epidemiological study should be performed to determine whether this type of smoking habit is associated with a statistically increased incidence of squamous cell carcinoma and keratoacanthoma of the lips.- - - - - - - - - - ranking = 1keywords = duct (Clic here for more details about this article) |
2/15. alendronate-related oral mucosa ulcerations.alendronate is widely used in the treatment of osteoporosis and other bone diseases. Although it is considered a well-tolerated drug, there are numerous reports of adverse effects on the mucosa in the upper aerodigestive tract, with oesophagitis as the most common complication. The strict regulations for the proper administration of the drug indicate that these side effects might well be the result of a direct, irritant mechanism on the upper aerodigestive tract. We present two clinical cases of patients who developed extensive palatal ulcers as a result of taking alendronate. We discuss possible mechanisms implicated in the production of the ulcers and some clinical factors of interest.- - - - - - - - - - ranking = 1keywords = duct (Clic here for more details about this article) |
3/15. Recurring anterior facial swelling.The nasolabial cyst was first reported in 1882. The most common clinical finding of the nasolabial cyst is that of an asymptomatic soft tissue swelling involving the canine fossa/nasal alar base region. The pathogenesis is controversial, but this cystic lesion most likely develops from the nasolacrimal duct. Microscopically, this cystic structure is composed of a fibrous capsule with an unremarkable layer of pseudostratified columnar epithelium. The treatment of choice is surgical excision, after which recurrence is rare.- - - - - - - - - - ranking = 1keywords = duct (Clic here for more details about this article) |
4/15. lip reduction cheiloplasty for Miescher's granulomatous macrocheilitis (cheilitis granulomatosa) in childhood.Miescher's granulomatous macrocheilitis (cheilitis granulomatosa) is a mono- symptomatic presentation of melkersson-rosenthal syndrome which is characterized by granulomatous swelling of the lips, and can affect both children and adults. We report the successful outcome following lip reduction surgery on an 11-year-old boy. We suggest that surgery may have a role in the management of those patients who have failed to respond to medical treatment.- - - - - - - - - - ranking = 5keywords = duct (Clic here for more details about this article) |
5/15. Orofacial granulomas after injection of cosmetic fillers. Histopathologic and clinical study of 11 cases.BACKGROUND: Purposely, cosmetic injections in orofacial tissues of various resorbable, biodegradable, or permanent fillers may be followed by development of foreign-body granulomas. The aim of this article is to contribute to the histologic identification of the filler material. methods: Histologic and clinical features of 11 cases of granulomas on orofacial fillers are described. RESULTS: Only 3/11 patients knew the nature of the injected product. Four histologic patterns were found: (i) Artecoll, (ii) Dermalive, and (iii) New-Fill granuloma, all three of the classic giant cell granuloma type, differing in respect of foreign particles; and (iv) Liquid Silicone granuloma, which featured a cystic and macrophagic type. Information was often missing or misleading, patients or practitioners being reluctant to give the details. CONCLUSION: Increasing demand for orofacial tissue augmentation makes pathologists face new, and sometimes, puzzling granuloma types. Identification of the foreign product might be required for therapeutic or medico-legal reasons.- - - - - - - - - - ranking = 2keywords = duct (Clic here for more details about this article) |
6/15. Bilateral nasolabial cysts associated with recurrent dacryocystitis.OBJECTIVE: Nasolabial cysts are rare, nonodontogenic, soft-tissue, developmental cysts occurring inferior to the nasal alar region. They are thought to arise from remnants of the nasolacrimal ducts and they are frequently asymptomatic. We report a rare case of bilateral nasolabial cysts accompanied by bilateral chronic dacryocystitis. CASE REPORT: A 48-year-old woman suffering from bilateral chronic dacryocystitis was referred to our department for endonasal dacryocystorhinostomy. She had undergone external dacryocystorhinostomy on the left side a few years earlier. physical examination and computed tomography scan revealed nasolabial cysts bilaterally inferior to the nasal alar region. The cysts were removed via a sublabial approach and endoscopic dacryocystorhinostomy was performed on the right side. Ten months after surgery, the patient was asymptomatic. CONCLUSION: There may be a correlation, due to embryological reasons, between the presence of nasolabial cysts and the presence of chronic dacryocystitis. Both can be corrected surgically, under the same anaesthesia, without visible scar formation.- - - - - - - - - - ranking = 1keywords = duct (Clic here for more details about this article) |
7/15. Delayed type allergic reaction following the use of nonlatex rubber dam during endodontic treatment.AIM: To describe the development of a delayed type allergic reaction 24 h following the use of nonlatex rubber dam during endodontic treatment. The symptoms were alleviated with adequate medication; however, the patient rejected any further analysis. SUMMARY: In recent years, allergic reactions because of latex rubber dam and gloves have received more attention. Nonlatex products are advocated in clinical use in cases where the patient presents an allergic background. Although rare, adverse reactions may be encountered even with these products. In this article, a very rare case is presented in which a patient developed signs of allergy 24 h after the utilization of nonlatex rubber dam and gloves during endodontic treatment. Signs including visible redness on the mucosa, submucosal oedema and desquamation in the vestibular mucosa were observed. With proper medication, the signs and symptoms were alleviated. Although the patient was referred to an allergy specialist for patch testing, she did not accept any further analysis. KEY learning POINTS: This case emphasizes the necessity of precautions during the management of latex-allergic patients in clinical practice. The unusual response encountered in this patient does not undermine the usefulness of nonlatex rubber dam and gloves in sensitive individuals.- - - - - - - - - - ranking = 2keywords = duct (Clic here for more details about this article) |
8/15. Delayed contact sensitivity on the lips and oral mucosa due to propolis-case report.We report a rare case of a patient who was referred to the Department of oral medicine in Zagreb, croatia. The patient was 20 years old, otherwise healthy and not taking any medication. She presented with irregular erosions partially covered with pseudomembranes that involved both lips and retrocomissural mucosa. Discrete erosion was also noticed on her lower lingual gingiva in the area 42. She reported a propolis solution self-medication for treatment of recurrent aphthous ulcers. After ten days of propolis application, lip and oral lesions developed. Patch test to propolis was proven. We highlight the fact that some folk medicine medications, such as propolis, although being known for many decades to be helpful in various conditions, in some individuals might lead to unwanted side-effects due to its antigenic potential. Additionally, every colleague, during the differential diagnosis of the oral lesions must bear in mind unwanted reactions to folk medicine products.- - - - - - - - - - ranking = 1keywords = duct (Clic here for more details about this article) |
9/15. Congenital midline sinus of the upper lip. Report of a case.An extremely rare case of congenital midline sinus of the upper lip in a 12-year-old girl is presented. The sinus had a pit-like orifice in the midline philtral area with a duct extending 4 mm posterosuperiorly. It was excised by extraoral elliptical incision. Histopathological examination disclosed that the duct was covered by a stratified squamous epithelium with sebaceous glands. Twelve cases of this rare disease have previously been reported.- - - - - - - - - - ranking = 2keywords = duct (Clic here for more details about this article) |
