ABSTRACT
El carcinoma adenoideo quístico de la glándula de Bartolino (GB) es una entidad infrecuente, de crecimiento lento y comportamiento agresivo con alta recurrencia local y metástasis. Presentamos el caso de una paciente de 48 años, con antecedente de tratamiento quirúrgico de un absceso Bartolino derecho. La biopsia demostró un carcinoma adenoideo quístico (CAQ) de la GB, por lo que se realizó hemivulvectomía radical derecha y linfadenectomía inguinofemoral. El resultado de la biopsia mostró 4 ganglios positivos de 12 y margen lateral positivo a menos de 2 mm. Por lo que se realizó adyuvancia con radioterapia. La paciente no se presenta a su control y acude luego de tres años por dolor urente desde cadera izquierda hacia rodilla y cara lateral de la pierna y pie. Se realiza cintigrama óseo que muestra lesión osteoblástica sacroilíaca izquierda de 2 cm, por lo que se completó estudio de diseminación con tomografía computada de tórax, abdomen y pelvis con contraste que evidenció múltiples lesiones nodulares pulmonares bilaterales de distribución generalizada en parénquima central, periférico y subpleurales. Se deriva al Instituto Nacional del Tórax, completando estudio preoperatorio y se realizó una biopsia quirúrgica por video toracoscopía resecando un nódulo subpleural, el informe histológico señaló una metástasis de CAQ concordante con primario en GB. La paciente fue presentada en el comité oncológico y se indicó radioterapia paliativa a lesión sacroilíaca y control clínico ambulatorio. Ha evolucionado estable desde el punto de vista funcional pulmonar.
Adenoid cystic carcinoma of Bartholin glands (BG) is a rare, slow-growing but a highly aggressive tumor with remarkable capacity for local recurrence and distant metastasis. We present the case of a 48 year-old female patient with a history of surgical treatment for right Bartholin abscess. The biopsy showed a cystic adenoid carcinoma of the BG, which led to radical hemivulvectomy and inguinofemoral lymphadenectomy. The biopsy show inguinal lymph node metastasis on 4 of 12 lymph nodes and positive surgical resection margin. Adjuvant radiotherapy was applied. The patient doesnt present to her clinical follow up, and consult three years later with radiological evidence of sacroiliac metástasis on bone scintigraphy. Study was completed with thorax, abdomen and pelvis tomography scan, and showed multiple bilateral lung nodules. The patient was transfered to National Thoracic Institute, and preoperative study was performed. We decide to obtain histologycal confirmation by a video thoracoscopy, it was performed without incidents. Histology show metastasis of adenoid cystic carcinoma pattern, concordant with primary tumor. The patient was submitted to the oncology committee and palliative radiotherapy was indicated for sacroiliac lesion. The patient evolve stable and asintomatic at ambulatory clinical control.

INTRODUCTION: Adenoid cystic carcinoma is the most frequent malignant tumor of the submandibular gland and the minor salivary glands. It is a malignant neoplasm that, despite its slow growth, shows an unfavorable prognosis. OBJECTIVES: The aim of this study was to perform a systematic review of the literature on Adenoid cystic carcinoma in the head and neck region and its clinicopathological characteristics, with emphasis on the perineural invasion capacity of the tumor. METHODS: A systematic search of articles published between January 2000 and January 2014 was performed in the PubMed/MEDLINE, SciELO, Science Direct, and Scopus databases. RESULTS: Nine articles were selected for this systematic review. These demonstrated that the female gender was more often affected and that malignant tumors showed a high rate of distant metastasis, recurrence, and a low survival rate. The presence of perineural invasion ranged from 29.4% to 62.5% and was associated with local tumor recurrence. CONCLUSION: Adenoid cystic carcinoma is commonly characterized by the presence of pain, high rate of recurrence, metastasis, and a low survival rate. Reporting studies with patient follow-up is of utmost importance for a better clinical-pathological understanding and to improve the prognosis of this pathology. .
INTRODUÇÃO: O carcinoma adenoide cístico (CAC) é o tumor maligno mais frequente da glândula Submandibular e das glândulas salivares menores. Sendo uma neoplasia maligna, apesar de ter crescimento lento, apresenta um prognóstico desfavorável. Objetivos: O objetivo deste trabalho foi realizar uma revisão sistemática de literatura sobreo carcinoma adenóide cístico na região de cabeça e pescoço e suas características clínico-patológicas com ênfase na capacidade de infiltração perineural do tumor. MÉTODO: Uma busca sistemática de artigos publicados entre janeiro de 2000 a janeiro de 2014 foi executada nas bases de dados PubMed/MEDLINE, SciELO, Science Direct e Scopus. RESULTADOS: Nove artigos foram selecionados para realização da revisão sistemática. Nestes, o sexo feminino foi o mais afetado e o tumor maligno apresentou uma alta taxa de metástase a distância, recidiva e baixa taxa de sobrevida. A presença de invasão perineural variou entre 29,4% a 62,5% e foi relacionada à recidiva local do tumor. CONCLUSÃO: O CAC é comumente caracterizado pela presença de dor, alta taxa de recidiva, metástase e baixa sobrevida. A realização de estudos com acompanhamento dos pacientes é de extrema importância para uma melhor avaliação clinico-patológica visando melhorar o prognóstico da doença. .

Adenoid cystic carcinoma, an uncommon malignant salivary gland neoplasm, is known for its long clinical course, indolent growth, local recurrence and late distant metastasis. We report an unusual case of adenoid cystic carcinoma of the palate in a 64-year-old woman, undiagnosed for more than 15 years, who presented as malignant pleural effusion.
