Langerhans cell histiocytosis with oral manifestations: a rare and unusual case report
2012
Langerhans cell histiocytosis (LCH), is a rare, proliferative disorder in which the accumulation of pathologic Langerhans cells leads to local tissue infiltration and destruction. We present a case of a 32 years old, completely edentulous female patient who presented with erythema of hard palate, maxillary alveolar mucosa and mucosa over the distobuccal part of mandibular alveolar ridge with foci of ulcerations. Histopathologic features were suggestive of LCH which was confirmed by immunohistochemistry which was CD1a positive, confirmatory for LCH. Bone scan revealed multiple bone involvement. At this stage, disease had already progressed to multisystem involvement with endocrinal abnormali…
Focal palmoplantar and gingival keratosis ? A rare genodermatoses : case report
2020
Focal palmoplantar and gingival keratosis syndrome is a rare dominant inherited disease with an early onset in life. Clinically, the condition is characterized by pressure related thickening of the epidermis of the palms and soles, usually accompanied by pain and different levels of skin involvement and thickness between patients. Recently, we observed a 38-year-old woman with multiple non-removable, painless white plaques of variable size and thickness on the attached gingiva and a white plaque widespread across the hard palate. By further questioning, the patient comments that she has thick yellowish focal plaques in both soles of her feet. Histopathological analysis revealed a hyperplast…
Symmetrical palatal fibromatosis: An additional case report with immunohistochemical characterization
2021
Background The term "symmetrical palatal fibromatosis" was recently suggested to designate bilateral palatal lesions presenting as typically broad, "mirror" images on the posterior lateral region of the hard palate. Purpose We report an additional case of this as-yet poorly understood oral lesion in a 67-year-old male patient, with emphasis on differential diagnoses and immunohistochemical characterization. Case Report The histopathological examination demonstrated a hypocellular, fibrous connective tissue with prominent thick collagen bundles and few blood vessels. Scattered large, stellate, and sometimes binucleated fibroblasts were found. Immunohistochemistry was positive for vimentin an…
Papillary cystoadenoma lymphomatosum (Warthin-like) of minor salivary glands
2009
Papillary cystadenoma lymphomatosum is a benign salivary gland tumor most frequently located in the parotid gland (Warthin?s tumor). Its presentation in other major, or in minor, salivary glands is rare. Clinically, it manifests as a slow growing tumor, fluctuant on palpation due to its cystic morphology. The treatment of choice is complete excision with wide tumor-free margins. We present a 73-year-old female patient with an asymptomatic tumor of 8 years evolution in the right posterior area of the hard palate. We performed surgical excision and a biopsy, which was reported as papillary cystadenoma lymphomatosum. During the post-operative examination carried out after 3 weeks, it was obser…
Oral findings in secondary syphilis
2018
Background Syphilis is a sexually transmitted disease caused by Treponema pallidum. However, there are of hematogenic and vertical transmission. All health care professionals must be aware of the manifestations of this condition, such as oral lesions. Objectives This study to analyze and compare four clinical cases of syphilis that were diagnosed based on lesions in the oral cavity with published literature. Material and Methods Four patients with a confirmed sorologic and clinical diagnosis of syphilis were examined, confirmated from manifestation of oral lesions together with analysis of serological laboratory tests and histopathological analyses. Results Lesions were found in classic sit…
Hyperpigmentation of hard palate induced by chloroquine therapy
2017
The antimalarials are one of the most commonly prescribed drugs for conditions such as lupus erythematosus and rheumatoid arthritis, and the side effects, though infrequent, are well known. The antimalarial agent chloroquine diphosphate usually causes pigmentary changes in the oral mucosa characterized by a bluish-grey to black discolorations mainly in the hard palate. Considering only the hard palate hyperpigmentation caused by chloroquine, to the best of our knowledge, only 13 cases have been reported in the English language literature. We described an additional case of palate hyperpigmentation related to the chronic use of chloroquine diphosphate in a 60-year-old Mexican woman. Although…
Melanoma of the oral mucosa with cerebral metastasis: a clinical case
2005
Summary Oral melanoma (OM) is an infrequent neoplasia making up less than 1% of all melanomas, and which exhibits a much more aggressive behaviour than those found on the skin. We present a case of OM located on the hard palate, vestibular alveolar gingiva of the maxilla, and upper lip in a 75-year-old patient who developed a distant metastasis on the left parietal lobe. The advanced stage of the disease contraindicated any surgical intervention and it was decided to carry out palliative radiotherapy, but the patient died before treatment.
Palatal perforations secondary to inhaled cocaine abuse: presentation of five cases
2010
The estimated incidence of complications associated with cocaine abuse is 4.8%. Palatal perforation is a very infrequent condition within the range of complications associated with cocaine abuse. No epidemiological cha- racteristics relating to patient age or gender have been established, and the diagnosis of the disorder requires a detailed clinical history, including antecedents of cocaine abuse. The clinical and radiological studies show palatal bone erosion and perforation of the soft or hard palate. The present study describes five cases of palatal perforation secondary to inhaled cocaine abuse. As a result of the increase in cocaine use in recent years, particularly among young adults…
Cocaine-related oronasal communication and hard palate destruction
2011
Four cases of midpalatal perforation in cocaine abusers are presented. Other potential etiological processes are discussed to establish an adequate differential diagnosis. These patients were treated at our department, due to the drawback promoted by the establishment of oronasal communication that was provided after an accurate diagnosis. Histopathological evaluation of the lesion margins were conducted in two of the four cases, and yielded no evidence of vasculitis or active cocaine abuse. Therapeutic approach consisted of reconstructive surgeries and/or sealing prostheses. Histological assessment of oronasal communication margins could be useful in establishing the persistence of active …
