ABSTRACT

SUMMARY: BACKGROUND: Metastatic tumors account for less than 1% of all malignant tumors occurring in the oral cavity. CASE REPORT: The clinical case of a 94-year-old patient with a mandibular tumor is reported here. The patient had undergone bilateral mastectomy more than 25 years before. An immunohistochemical study found hormone receptors in signet ring cells, suggesting a diagnosis of breast cancer metastasis. CONCLUSION: Immunohistochemical diagnosis and antineoplastic hormone therapy is the cornerstone in the management of this clinical case.

ABSTRACT

Antecedentes: El incremento en el diagnóstico del cáncer de próstata en la última década en nuestros hospitales ha llevado consigo un aumento similar en el número de prostatectomías radicales. En este trabajo se analizan las diferencias histológicas observadas entre los pacientes tratados con cirugía radical en los años 1999 y 2006 y se evalúa la evolución habida en la indicación de cirugía radical en un lapso de 7 años. Métodos: Se analizan de forma comparativa los datos histológicos de las prostatectomías radicales, y de sus biopsias transrectales previas, diagnosticadas en 1999 y en 2006. Sólo se han incluido en el análisis los casos con la totalidad de los datos evaluables tanto en la biopsia como en la cirugía. En las biopsias transrectales se valoran la afectación uni o bilateral, el número de focos de tumor, los milímetros totales de tumor, la presencia de PIN de alto grado, el índice de Gleason, y la invasión perineural. En las prostatectomías radicales se evalúa el estadio (pT), el índice de Gleason, la presencia de PIN de alto grado, la invasión de los bordes, la afectación del ápex, la invasión perineural y vascular, la extensión extraprostática, y la invasión de las vesículas seminales. El estudio estadístico comparativo entre ambos grupos se realiza mediante pruebas de c2, t de Student, y Mann-Whitney. Resultados: El estudio incluye 24 prostatectomías radicales de 1999 y 50 de 2006. El pT es significativamente más bajo en 2006 que en 1999 (p=0,032). Asimismo, hay mayor número de carcinomas organo-confinados en 2006 (p=0,034). Además, la extensión extraprostática del cáncer y la invasión de vesículas seminales son significativamente menores en 2006 (p=0,090 y p=0,011, respectivamente). Conclusiones: En 2006, entre los pacientes que han sido tratados con cirugía radical, se observa una disminución significativa en el estadio tumoral. El número de casos con extensión extraprostática y con invasión de vesículas seminales es, asimismo, menor


Background: The increase in number of prostate cancer diagnoses in the last decade is accompanied by a similar increase in the number of radical prostatectomy specimens. We analyse the histological differences between patients treated with radical surgery in 1999 and in 2006. The evolution in the indications for surgery is also evaluated. Methods: Histological data in core biopsies and radical prostatectomies of cases diagnosed in 1999 and 2006 have been compared. Only cases with complete histological information have been included in the study. Bi/unilateral tumour invasion, number of tumour foci, total millimetres of cancer, high-grade PIN, Gleason index, and perineurial invasion have been evaluated in core biopsies. Pathological staging, Gleason index, high-grade PIN, margin status, apex invasion, perineurial and vascular permeation, extraprostatic extension and seminal vesicle invasion have been analysed in radical prostatectomies. The statistical study included c2, Student’s t, and Mann-Whitney test. Results: The study includes 24 radical prostatectomies in 1999 and 50 in 2006. The pathological staging is significantly lower in 2006 than in 1999 (p=0.032). Similarly, organ-confined disease is more frequent in 2006 (p=0.034). Extraprostatic extension and seminal vesicle invasion by prostate adenocarcinoma are significantly lower in 2006 (p=0.090 y p=0.011, respectively). Conclusions: Prostate adenocarcinoma patients treated with radical surgery in 2006 are at a lower stage compared with 1999 cases

ABSTRACT

Introducción: La hipertrofia adiposa del septo interauricular es cada vez más frecuentemente reconocida gracias al desarrollo creciente de las técnicas de imagen no invasivas. Presentación del caso: Se presenta el caso de una paciente de 72 años de edad aquejada de angina de esfuerzo a la que en el estudio clínico se detectó una hiperplasia adiposa del septo interauricular. El estudio de la pieza de resección quirúrgica mostró la histología típica de esta entidad, con adipocitos maduros y lipoblastos entremezclados con fibras musculares cardiacas. Conclusiones: Aunque esta patología es relativamente frecuente, rara vez necesita ser corregida quirúrgicamente, motivo por el cual los patólogos la suelen diagnosticar en el estudio autópsico. Se revisa la literatura reciente en relación con las lesiones adiposas auriculares


Introduction: Lipomatous hypertrophy of the atrial septum is diagnosed more frequently after the use of non-invasive imaging techniques. Case presentation: A case of lipomatous hypertrophy of the atrial septum in a 72 year-old woman who consulted because of effort-related angina is reported. The study of the excised tissue fragments showed the typical histology, with mature adipocytes and lipoblasts intermingled with cardiac muscle fibres. Conclusions: This lesion is relatively frequent but surgical treatment is rarely needed. So, pathologists take contact with it mainly in the autopsy. The recent literature related to atrial lipomatous lesions is reviewed (AU)

ABSTRACT

INTRODUCTION: Inflammatory myofibroblastic tumor (IMFT) of the temporal bone is an unusual but distinct clinicopathologic entity. CASE REPORT: We report the case of a 75-year-old patient with an IMFT located in the temporal bone. Symptoms included VI, X, XI, and XII cranial nerves palsies. Computed tomography and magnetic resonance images are described. The lesion was locally aggressive and outcome was fatal. IMFT was identified by analysis of postmortem specimen with histopathologic and immunohistochemical confirmation. DISCUSSION: IMFT can be locally destructive lesions. Involvement of the skull base and cervical spine is indistinguishable from an aggressive infection or a malignant tumor and can be fatal as in our case report. The difficulties in establishing clinicopathologic diagnosis, radiological imaging characteristics, and treatment are discussed.

ABSTRACT

Basaloid squamous cell carcinoma (BSCC) is a rare and aggressive variant of cancer that mainly arises in the upper aerodigestive tract. This study reviews the clinico-pathological features and follow-up of a series of cases occurring in the head and neck. During a 32-year period (1974-2005), a total of 40 BSCCs have been diagnosed in the head and neck in our Institution. Males predominated in the series (35M/5F). The average age was 60.2 years (range, 40-85). Tobacco and alcohol consumption was found in more than 80% of the cases. Topographic distribution was as follows: larynx and hypopharynx, 22 cases (55%); oropharynx, 12 cases (30%); and oral cavity 6 cases (15%). The basaloid component predominated in 29 cases (72.5%). Vasculo-lymphatic invasion was detected in 5 cases (12.5%). Lymph node metastases were seen in 25 cases (62.5%, levels II and III in the neck dissection). Local recurrences appeared in 11 cases (27.5%) and distant metastases in 6 (15%). In 7 cases (17.5%) a second primary tumour was detected. The 2002 TNM staging was as follows: Stage I, 5 cases (12.5%); Stage II, 7 cases (17.5%); Stage III, 8 cases (20%), and Stage IV, 20 cases (50%). On follow-up, 21 cases (52.5%) are alive and 19 (47.5%) died of disease. Three- and 5-year overall survival was 50% and 38.5%, respectively. A significant shorter survival was detected in node positive patients (P<0.05).

ABSTRACT

A 44-year-old woman presented with a history of increasing left hypoacusis and sporadic vertigo. CT scan revealed a tumor occupying the mastoid, middle ear, and external auditory canal. After surgical removal, a typical secretory meningioma was diagnosed. The histological hallmark and the immunohistochemical profile of secretory meningiomas are reviewed. The differential diagnosis of this tumor in this location is also commented on. As far as we know, primary temporal bone meningiomas with secretory histology have not been previously reported in the medical literature.

ABSTRACT

Se trata de un varón de 28 años de edad que acude alurólogo por presentar un leve aumento de volumen del testículoderecho. El estudio ecográfico muestra un tumor sólidointratesticular de aproximadamente 1 cm de diámetro. Lapieza de orquiectomía radical muestra un tumor con un grancomponente de fibrosis estromal en el que aparecen cordonesde células cuboideas sin atipia citológica ni mitosis, quemuestran positividad para citoqueratinas, vimentina y calretinina.El tumor de células de Sertoli es una neoplasia muypoco frecuente en el testículo. La variedad esclerosante, queha sido descrita recientemente, es aún más rara y comportadiferente pronóstico. En este trabajo se revisa los criteriosmorfológicos diagnósticos y las peculiaridades clínicasrecogidas recientemente en la literatura


Background: Sertoli cell tumor is an unfrequent neoplasmof the testis and the recently reported sclerosingvariant is even rarer, and seems to have a different prognosis.Patients and Methods: A 28 year-old man consultedthe urologist because of a slight increase in right testicularvolume. Echographic examination revealed an intratesticularsolid tumor, 1 cm in diameter. Radical orchiectomy showedan intratesticular sclerotic tumor composed by sheetsand cords of cuboidal benign appearing cells. Immunostainingsfor cytokeratins, vimentin, and calretinin were done.Atypia and mitoses were not found. An analysis of diagnosticmorphological criteria and clinical peculiarities describedin previous recent reports was done

ABSTRACT

Describimos el caso clínico de una paciente de 18 años de edad, que acudió a nuestra consulta por presentar un episodio febril con odinofagia, de 10 días de evolución. El paciente presentaba una fístula preauricular derecha y un tracto fibroso que progresaba en sentido caudal y anterior hacia el cuello. La inspección de la cavidad oral demostraba la existencia de una protusión amigdalar derecha. En la T.A.C. y R.M.N. realizadas se objetivaba una tumoración quística periamigdalar que se comunicaba mediante un trayecto fistuloso con un orificio preauricular. El informe anatomo-patológico de la pieza quirúrgica nos informó de la existencia de un Quiste Branquial y de un trayecto fistuloso afectado por la existencia de un Tricofoliculoma, una tumoración benigna cervico-facial de escasa incidencia en lo referente a su localización en el primer arco branquial


We report a case of a 18 years old male patient who presented a ten days history of fever and odinophagia.The patient presented a preauricular fistule and a fibroustract in the right side. Oral cavity inspection showed atonsil displacement.Computed Tomography and Magnetic Resonance images indicated the existence of a first branchial arch cyst. The histophatologhical study confirmed the presence of a Branchial Cyst and a Trichofolliculoma in the fistule, an unusual benign tumour originated in the first branchialarch

ABSTRACT

A case of primary ameloblastoma of the right sinonasal tract in a 66-year-old man is reported. The tumour presented as a radiographically solid mass filling the right nasal cavity and sinuses and without continuity with maxillary alveola. After radical surgery plus postoperative radiotherapy, the patient has pursued a non-aggressive clinical course after nine months of follow-up. The paper reviews the clinico-pathological features of this rare tumour and supports the theory of its sinonasal epithelium origin.

ABSTRACT

Se aporta la observación de un caso de trisomía 1q parcial asociada a manifestaciones fenotípicas y anatomopatológicas propias de la anomalía de Di George. La variable expresión de la misma parece correlacionarse con distintas circunstancias asociadas, que se interpretan como causantes de la mencionada anomalía. Los autores establecen la relación entre cromosomopatía y alteración fenotípica, sugiriendo la obligatoriedad del estudio citogenético de aquellos cuadros que clínicamente correspondan a los distintos grados de síndrome de Di George
