Adenoma pleomorfo originado en pared lateral nasal: reporte de un caso clínico / Pleomorphic adenoma of lateral nasal wall: a case report

RESUMEN El adenoma pleomorfo constituye la neoplasia benigna más frecuente de las glándulas salivales mayores, y puede también presentarse en otros sitios con mucha menor frecuencia como orofaringe, hipofaringe y nasofaringe. El adenoma pleomorfo intranasal es muy infrecuente y los casos descritos en la literatura local se refieren a tumores septales. Se presenta un caso clínico de una paciente que consulta por obstrucción nasal unilateral a derecha asociado a, epistaxis y epífora ipsilateral con estudio imagenológico y biopsia que sugiere adenoma pleomorfo de la pared lateral nasal. Se realiza revisión bibliográfica al respecto.

ABSTRACT The pleomorphic adenoma is the most frequent benign neoplasm of the major salivary glands. It can also present itself in other places with much less frequency such as oropharynx, hypopharynx and nasopharynx. The intranasal pleomorphic adenoma is very unusual and the cases described in the local literature address septal tumors. A clinical case is presented of a patient who consulted for unilateral right nasal obstruction associated with epistaxis and ipsilateral epiphora with imaging study and biopsy suggesting pleomorphic adenoma of the lateral nasal wall. A bibliographic review is made in this regard.

Adenoma pleomórfico de paladar en un paciente joven: reporte de caso / Pleomorphic adenoma of the palate in a young patient: Case report

El Adenoma Pleomórfico (AP) es el tumor benigno más común de la glándula parótida, aunque se presenta frecuentemente en glándulas salivales mayores, puede encontrarse en glándulas salivales menores del paladar y del labio, siendo infrecuente en pacientes jóvenes; se detecta en muchos casos como un hallazgo casual durante el examen clínico odontológico, puede evaluarse a través de diferentes estudios imagenológicos y su diagnóstico definitivo se basa en el análisis histopatológico de la lesión. El tratamiento quirúrgico dependerá de la localización y del tamaño. En pocos casos presenta recidiva y la trasformación maligna es rara, pero es necesario realizar un seguimiento periódico a largo plazo después de su exéresis. A continuación se presenta el caso de un adenoma pleomórfico de glándula salival menor localizado en el paladar duro de una paciente de 16 años de edad, diagnosticado y tratado oportunamente mediante la resección completa con un margen adecuado de tejido sano, con un pronóstico favorable...

The Pleomorphic Adenoma (PA) is the most common benign tumor of salivary glands, although frequently in major salivary glands can be found in minor salivary glands of the palate and lip, are uncommon in young patients; often detected as an incidental finding during dental clinical, examination can be assessed by different imaging studies and definitive diagnosis is based on histopathological analysis of the lesion. The surgical treatment depends on the location and size. In a few cases presented recurrence and malignant transformation is rare, but it is necessary to regularly monitor long term after excision. A case is reported of pleomorphic adenoma of minor salivary gland located in the hard palate in a 16 year old girl, diagnosed and treated by complete resection with an adequate margin of healthy tissue, with a favorable prognosis...

Laterality of pleomorphic adenoma of parotid gland

Although pleomorphic adenoma is the commonest benign tumor of both major and minor salivary glands, yet it bears certain peculiar characters like invariable growth rate, short spells of spurts of growth, long quiescent periods, invasion of surrounding tissues by its capsular projections, recurrence, notorious for implantation and classic origin from the tail of parotid gland. Since the nerve of facial expression [facial nerve] falls within the domain of otolaryngologists but its course along with its variable branches through the parotid gland has always remained an area of common interest between general and ENT surgeons. With the more and more involvement of E.N.T. surgeons in head and neck oncology, the cancer of salivary glands looks to be being taken over by them in recent decades. FNAC inspite of its accuracy is loosing its superiority over modern ultrasonography. This is an observational study. This study was carried out in Combined Military Hospital Lahore from Feb 2005 to Feb 2008. A total of 28 patients with unilateral mass of parotid gland, all with FNAC [Fine needle aspiration cytology] positive for pleomorphic adenoma were included in the study without any discrimination of age, sex or size of tumor. Each patient underwent CT scan and surgical modality of treatment was selected for every patient with post-operative histopathology study to confirm or otherwise of FNAC diagnosis. Female male ratio was 3:4, mean age in males was 44, in females was 37. Histopathology-disproved FNAC in 7.14%. Ratio between involvement of superficial lobe and both lobes was 13:1. Post-operative transient facial nerve paresis was seen in 12 out of 28 patients and there was surprising laterality of right parotid involvement, ratio between right and left parotid being 11:3. Smallest tumor at presentation was 3x3 centimeter and largest was 14x10 centimeter in size. Markedly more incidence of pleomorphic adenoma on right side of face is observed. It has not been reported previously. Zero percent facial nerve severance in 28 parotidectomies reflects vigilance and surgical skill of today's otorhinolaryngologists

A large pleomorphic adenoma of soft palate causing sleep apnea syndrome--a case report.

Pleomorphic adenoma of soft palate is extremely rare. A large tumour in soft palate is reported with sleep apnea syndrome. Diagnosis was made by fine needle aspiration cytology and intraoperative consultation by imprint smears, which were confirmed by histopathological and immunohistochemical studies.
