2014
Background : To determine the incidence and prevalence of salivary gland tumours in the province of Valparaíso, Chile. Material and Methods : Retrospective review of salivary gland tumours diagnosed between the years 2000 and 2011 from four local pathology services. Information on demographics and histopathology were retrieved from the medical records. Results : The study sample consisted of 279 salivary gland tumours. Prevalence and incidence rates per 100.000 persons were 15.4 and 2.51, respectively. Most of the neoplasms corresponded to benign tumours (70.3%). The most affected gland was the parotid gland. Pleomorphic adenoma was the most common benign tumour (53.8%) and mucoepidermoid c…
Solitary intraosseous neurofibroma of the mandible. Apropos of a case
2010
Neurofibroma is a benign neoplasm derived from peripheral nerves. Most of these are associated with Neurofibromatosis but may also occur as solitary lesions. When found on the head and neck they are generally located in the soft tissue. Intraosseous location is very rare. The following report describes a case of an intraosseous neurofibroma located in the left mandibular ramus of a 14-year-old child. The patient did not had clinical evidence of the lesion and it was found on a routine radiographic examination. Surgical excision of the lesion was scheduled and the sample was submitted to histopathological study. Representative sample cuts were studied using conventional techniques of hematox…
Cowden's syndrome diagnosed through oral lesions : a case report
2021
Cowden's syndrome (CS), also known as multiple hamartoma syndrome, is a rare autosomal dominant genodermatosis first described in 1963. It has a high penetrance in both sexes and variable phenotypes. Its origin is a PTEN (phosphatase and tensin homologue) gene mutation and affects multiple organs of endodermal, ectodermal, and mesodermal origin, resulting in the development of hamartomatous mucocutaneus lesions and an increased risk for malignancies in breast, thyroid, endometrium, kidney, colon, rectum, among other organs. The diagnosis of CS is based mainly on clinical findings and oral cavity manifestations are frequent, occurring in 80-90% of patients. This include oral and labial papil…
