We describe two additional cases of solitary fibrous tumour (SFT) affecting the mouth. SFT is very uncommon in the oral cavity and we found only 14 cases reported in the literature. Our two cases were well circumscribed, slow growing tumours that, after surgical removal, did not recur. Case 1 was a 3 cm nodule on the right cheek. Hypo and hypercellular(More)
OBJECTIVE Salivary gland tumors in children and adolescents are rare. Most papers are case reports or short series of cases. The aim of this study was to analyze clinicopathological and immunohistochemical data from a large series of salivary gland tumors affecting youngsters from a single institution. METHODS From 1953 to 1997, 53 patients 18 years old(More)
The correct diagnosis of high-grade mucoepidermoid (MEC), which is composed of solid islands of intermediate and squamous cells, may be challenging, due to its similarity to other tumours, mainly with squamous cell carcinoma (SCC). The present report employed immunohistochemical technique against different cytokeratins (CKs), in order to differentiate these(More)
Hereditary Gingival Fibromatosis (HGF) is the most common genetic form of gingival fibromatosis. The condition is most frequently reported to be transmitted as an autosomal-dominant trait, but autosomal-recessive inheritance has also been reported. The clinical presentation of HGF is variable, both in the distribution (number of teeth involved) and in the(More)
One of the main opportunistic fungal infections amongst immunocompromised individuals is oral candidosis, which has been found in up to 90% of human immunodeficiency virus (HIV)-infected patients. This study employed yeasts isolated from the saliva and oral cavities of 114 HIV-infected patients living in Campinas, São Paulo. Of the isolates, 57.8% were(More)
Paracoccidioidomycosis (Pmycosis) is one of the most common deep mycoses in many regions of Latin America, particularly in Brazil. Microscopically, it shows granulomatous inflammatory reaction with giant cells, macrophages, lymphocytes, plasma cells, polymorphonuclear neutrophilic leukocytes, and eosinophils. The purpose of this study was to assess the(More)
Sebaceous carcinoma (SC) is a rare malignancy, affecting mainly the periocular glands. To the best of the authors' knowledge, this is the first English-language report of parotid SC affecting children; two cases are presented. Immunohistochemical studies included 29 different antibodies (15 of these were cytokeratins, CKs). For each case, DNA ploidy status(More)
OBJECTIVE The aim of this study was to assess the clinical and histologic features of 6 cases of sublingual salivary gland tumors treated in a single institution. STUDY DESIGN The clinical data were obtained from the medical records, and the histopathologic slides were reviewed. RESULTS Four cases were adenoid cystic carcinoma (ACC) and 2 were(More)
Hereditary gingival fibromatosis (HGF) is a rare oral condition characterized by a slow and progressive enlargement of the gingiva, involving both the maxilla and mandible. In vitro, HGF fibroblasts demonstrate a proliferative index significantly higher than fibroblasts from normal gingiva (NG). The objective of this study was to determine the effect of(More)
