Synchronous unilateral parotid neoplasms. A case report

The parotid gland is the most usual location of benign neoplasms affecting major salivary glands and quite oftenthe recurrence of these tumours is noticed, specially in the case of pleomorphic adenoma. The occurrence of multipletumours in the parotid glands is rare and the majority of these are multifocal Warthin`s tumors (papillary cystadenomalymphomatosum). The simultaneous development of tumours with different histological types is unusualand when it occurs, the most common combination is a pleomorphic adenoma and a Warthin`s tumor. There aremany articles about Multiple Parotid Tumors (MPT) but only a few of them are focused on unilateral synchronousbenings tumors, being pleomorphic adenoma and Warthin´s these tumors.The report describes a 55 year old female with a pleomorphic adenoma occurring synchronously with a Warthin`stumor within the superficial lobe of her left parotid gland (AU)

Quiste odontogénico calcificante asociado con odontoma complejo: Presentación de un caso y revisión bibliográfica / Calcifying odontogenic cyst associated with complex odontoma: Case report and review of the literature

Se presenta un caso de quiste odontogénico calcificante asociadocon odontoma (QOCaO) y con un canino permanente incluidoen maxilar superior, en un paciente varón de 19 años.El Quiste Odontogénico Calcificante (QOC) fue descrito porprimera vez cómo una entidad patológica por Gorlin y col. en1962.Se trata de un tumor benigno odontogénico mixto,y aunquela mayoria de estas lesiones presentan características quísticasen algunos casos se presenta como una masa sólida (15 %), ysu transformación maligna está bien documentada. El QOC sepresenta en ocasiones asociado a otros tumores odontogénicos,el más común es el odontoma al que aparece relacionado en el24% de los casos. Para esta asociación se ha sugerido el términode „Quiste Odontogénico Odontocalcificante‰.Radiológicamente es una lesión mixta, bien definida y quehistológicamente consiste en un gran quiste en cuya parte centralexiste un área sólida con acúmulos de esmalte y dentinadistribuidos irregularmente en algunas zonas y en otros lugaresadopta un aspecto organoide bien definido.Se efectúa una revisión de la literatura y se discute su patogénesis

Calcifying odontogenic cyst associated with complex odontoma: case report and review of the literature.

We report a calcifying odontogenic cyst associated with odontoma (COCaO) and an included permanent canine in the superior maxilla, in a 19 year-old-man. The calcifying odontogenic cyst (COC) was first described as a distinct entity by Gorlin et al in 1962. The lesion is a mixed odontogenic benign tumor, and although most of the cases present cystic characteristics, a few are of the solid type (15%), and its rare malignant transformation is well documented. The COC may occur in association with other odontogenic tumors, the most common is the odontoma, occurring in about 24% of the cases. For this association the term Odontocalcifying odontogenic cyst has been suggested. Radiographically is a well defined mixed lesion and histologically consists of a large cyst. In the central area of the cyst enamel and dentin deposits can be found, irregularly distributed in areas and in other parts it takes on a well defined organoid aspect. A thorough review of literature takes place and the pathogenesis is discussed.

Pleomorphic adenoma of the parotid in childhood.

INTRODUCTION: Pleomorphic adenoma is a benign growth that most often appears in the parotid gland where it is the most frequent type of tumour. Its appearance in childhood is rare and there are no large series available in this age group for comparison with its presentation in adults. Surgical treatment is similar in children and in adults; whilst the prognosis is good, they may become malignant and metastasize. MATERIAL AND METHOD: In this study, we present seven parotid pleomorphic adenomas in childhood treated in our Department and a review of the literature. The following data were evaluated: sex, age, affected side, clinical symptoms and period of evolution of the symptoms, surgical technique applied and complications observed. RESULTS: The mean age at presentation was 12.4 years. All patients were males with the right side affected in five patients. The treatment was conservative superficial parotidectomy in five patients, conservative total parotidectomy in one, and an enucleation including a wide safety margin in the last case. None of the patients exhibited any permanent postoperative complication. The mean follow-up was 41.3 months (26-58 months).

Calcifying epithelial odontogenic tumor (Pindborg tumor).

We report a clinical case of a 41-year-old female patient affected by a Pindborg tumor located in the left mandibular angle. The accidental detection of the lesion and its frequent relationship with an impacted tooth can difficult its differential diagnosis, mainly with an odontogenic cyst. In spite of the existence of a recurrence rate of 14% after conservative treatment, we think that a quality treatment would require the practice of a block excision including healthy bony margins.

Tumor odontogénico epitelial calcificarte (tumor de Pindborg) / Calcifying epithelial odontogenic tumor (Pindborg tumor)

En este artículo presentamos y discutimos el caso clínico de una paciente de 41 años afecta de un tumor de Pindborg que asentaba en el ángulo mandibular izquierdo. La detección de la lesión de forma casual o rutinaria y la frecuente relación que ésta tiene con un diente incluido pueden hacer difícil la diferenciación principalmente con un quiste odontogénico. Pese a la existencia de una tasa de recurrencias del 14 por ciento tras un tratamiento conservador, pensamos que un tratamiento de calidad exige la práctica de una exéresis de la lesión con márgenes óseos sanos (AU)

Edema angioneurótico orofaríngeo causado por enalapril / Angioneurotic edema caused by ACEI: a case report

Aunque el consumo de fármacos inhibidores de la enzima convertidora de angiotensina presenta un bajo índice de efectos indeseables, en raras ocasiones se producers cuadros de edema angioneurótico localizados en el area orofacial y laríngea. El intervalo de aparición de este cuadro oscila entre las primeras horas y varios años desde el inicio de la toma del fármaco. Se presenta el caso de un hombre de 70 años, hipertenso, que desde hacía tres años tomaba enalapril. Fue ingresado en nuestro hospital por presentar un edema orolingual intenso, con dificultad para el lenguaje y disnea moderada. Se realizó un tratamiento con glucocorticoides, antihistamínicos y oxigenoterapia con mascarilla facial. No fue necesaria la intubación del paciente. El cuadro se resolvió a las 48-72 horas (AU)
