Salivary gland tumors in patients with necrotizing sialometaplasia: a case series
2013
Necrotizing sialometaplasia of the tonsillar pillar. An unusual case
2021
Necrotizing Sialometaplasia (NS) is a rare, benign, self-limited, inflammatory and necrotizing reaction of the salivary glandular tissue. Due to the clinical picture (a painful ulcer with well-defined edges), and histopathological characteristics (nuclear and cellular pleomorphism of ductal cells) NS can mimic a malignant lesion. The correct diagnosis is important because NS shows a spontaneous resolution and therefore no further treatment is needed. We report a very unusual case of spontaneous and recurrent NS located on the anterior tonsillar pillar in a 43-year old man, which clinically mimics a malignant lesion. The clinician should be aware to include NS in the differential diagnosis o…
Case report of necrotizing sialometaplasia
2010
Introduction: Necrotizing sialometaplasia is a rare inflammatory necrotizing reactive process that can involve minor and major salivary glands. Gland tissue ischaemia has been proposed as the aetiology. Case Report: A 21-year-old woman was referred with a 1-week history of bilateral painful swelling of the palate, with the development of two deep ulcers after the first 3 days. Ulcer edges were elevated but not indurated, and the bases had a necrotic appearance. An incisional biopsy of the margin of one ulcer confirmed the diagnosis of necrotizing sialometaplasia. The ulcers spontaneously healed within 8 weeks without treatment. Discussion: The clinical and histological similarity between th…
Sialometaplasia Necrotizante: Presentación de cinco casos clínicos
2004
La sialometaplasia necrotizante (SN) es una afección inflamatoria, autoresolutiva, que afecta a las glándulas salivales, más frecuentemente a las menores. Si bien su etiopatogenia permanece aún desconocida, diversos autores sugieren que una agresión fisico-química o biológica sobre los vasos sanguíneos produciría isquemia, la cual conduciría al infarto de la glándula y su posterior necrosis. Su aspecto clínico e histológico tiene apariencias de malignidad. Clínicamente puede presentarse como una úlcera de bordes irregulares, ligeramente elevados y lecho necrótico, mientras que histopatológicamente se caracteriza por presentar metaplasia escamosa de conductos y acinos e hiperplasia pseudoepi…
Estudio de la sialometría en un grupo de 103 pacientes con Síndrome de Sjögren y su relación con los criterios diagnósticos establecidos en esta enfe…
2021
El Síndrome de Sjögren (SS) es una exocrinopatía sistémica de naturaleza autoinmune y etiología desconocida, cuyo componente más llamativo es una infiltración por linfocitos T y B en las glándulas con función exocrina, fundamentalmente las glándulas salivales y lagrimales. Las principales asociaciones de reumatología han empleado la sialometría en reposo como uno de los criterios más empleados para el diagnóstico de esta enfermedad. Sin embargo, son muchos los autores que han señalado que esta sialometría es un test muy influenciable por factores externos como la edad, ciclos circadianos, temperatura ambiente, medicación, técnica de recogida, enfermedades, etc. En consecuencia, hemos consid…

An updated insight into the Sialotranscriptome of Triatoma infestans: developmental stage and geographic variations
2014
Background Triatoma infestans is the main vector of Chagas disease in South America. As in all hematophagous arthropods, its saliva contains a complex cocktail that assists blood feeding by preventing platelet aggregation and blood clotting and promoting vasodilation. These salivary components can be immunologically recognized by their vector's hosts and targeted with antibodies that might disrupt blood feeding. These antibodies can be used to detect vector exposure using immunoassays. Antibodies may also contribute to the fast evolution of the salivary cocktail. Methodology Salivary gland cDNA libraries from nymphal and adult T. infestans of breeding colonies originating from different loc…
