Prevalencia y concordancia entre diagnóstico clínico y anatomopatológico de demencia en una clínica psicogeriátrica / Prevalence and concordance between the clinical and the post-mortem diagnosis of dementia in a psychogeriatric clinic

Introducción: Describir los tipos de demencia en una serie de pacientes valorados en una clínica psicogeriátrica y estimar el grado de acuerdo entre el diagnóstico clínico y el anatomopatológico. Material y métodos: Realizamos un análisis descriptivo de la prevalencia de los tipos de demencia entre los pacientes valorados en nuestro centro y establecemos el grado de concordancia entre el diagnóstico clínico y el anatomopatológico. Los diagnósticos se establecieron en función de los criterios diagnósticos vigentes en cada momento. Resultados: Ciento catorce casos cumplieron los criterios de inclusión. Los diagnósticos más frecuentes tanto a nivel clínico como anatomopatológico fueron enfermedad de Alzheimer y demencia mixta, pero la prevalencia se invirtió pasando de un 39% y 18% a nivel clínico a un 22% y 34% a nivel anatomopatológico respectivamente. La concordancia entre el diagnóstico clínico y el anatomopatológico fue de un 62% (IC 95%: 53-72%). Conclusiones: Casi un tercio de nuestros pacientes no tenía un diagnóstico certero en vida, fundamentalmente a expensas del infradiagnóstico a nivel clínico de la enfermedad cerebrovascular (AU)

Introduction: The aim of our study is to describe the types of dementia found in a series of patients and to estimate the level of agreement between the clinical diagnosis and post-mortem diagnosis. Material and Methods: We conducted a descriptive analysis of the prevalence of the types of dementia found in our series and we established the level of concordance between the clinical and the post-mortem diagnoses. The diagnosis was made based on current diagnostic criteria. Results: 114 cases were included. The most common clinical diagnoses both at a clinical and autopsy level were Alzheimer disease and mixed dementia but the prevalence was quite different. While at a clinical level, prevalence was 39% for Alzheimer disease and 18% for mixed dementia, in the autopsy level, prevalence was 22% and 34%, respectively. The agreement between the clinical and the autopsy diagnoses was 62% (95% CI 53-72%). Conclusions: Almost a third of our patients were not correctly diagnosed in vivo. The most common mistake was the underdiagnosis of cerebrovascular pathology (AU)

[Scalp metastasis as the first manifestation of mixed follicular-papillary thyroid cancer]. / Metástasis en cuero cabelludo como primera manifestación de cáncer de tiroides mixto folicular-papilar.

Distant metastases are a rare occurrence in differentiated thyroid cancer, and when detected in skin, often arise in the context of disseminated disease after many years of progression since diagnosis. This study presents the case of a 77-year-old female without known thyroid disease, who presented with metastases in the parieto-occipital scalp region, in which thyroid tissue was identified. Thyroid ultrasound identified a nodule reported as a follicular tumour and preoperative investigation of tumour spread was negative. Total thyroidectomy plus central lymph node dissection were performed and histopathology reported mixed papillary-follicular carcinoma without lymph node metastasis. Lung micrometastases were detected in the post-I131 whole-body scan (104.7 mCi dose), and two months after a second dose of 131I (125 mCi), thyroglobulin was undetectable. Thyroid cancer should be included in the differential diagnosis of cutaneous metastases, since with early diagnosis and treatment, prognosis is generally more favourable than in other solid tumours.

Metástasis en cuero cabelludo como primera manifestación de cáncer de tiroides mixto folicular-papilar / Scalp metastasis as the first manifestation of mixed follicularpapillary thyroid cancer

La aparición de metástasis a distancia en los cánceres diferenciados de tiroides es poco frecuente, y cuando se detectan en piel, suelen darse en el contexto de una enfermedad diseminada después de muchos años de evolución desde el diagnóstico. Se presenta el caso de una paciente de 77 años, sin enfermedad tiroidea conocida que debutó con una metástasis en región parietooccipital del cuero cabelludo en la que se identificó tejido tiroideo. En la ecografía tiroidea se identificó un nódulo informado como tumor folicular y el estudio de extensión precirugía fue negativo. Se le hizo tiroidectomía total más vaciamiento ganglionar del compartimento central y el estudio AP fue informado de carcinoma mixto folicular-papilar sin afectación ganglionar. En el RCT post-I131 (dosis de 104,7 mCi) se detectaron micrometástasis pulmonares, y a los 2 meses de una segunda dosis de I131 (125 mCi), la tiroglobulina fue indetectable. El cáncer tiroideo debe incluirse en el diagnóstico diferencial de las metástasis cutáneas, puesto que su diagnóstico y tratamiento temprano, excepto en los casos de enfermedad muy avanzada, el pronóstico de su hallazgo suele ser más favorable que en el resto de tumores sólidos (AU)

Eccrine porocarcinoma. Report of nine cases.

BACKGROUND: Eccrine porocarcinoma is a rare malignancy of the eccrine sweat gland and usually has a long-standing growth on a lower extremity. OBJECTIVE: The aim of this review was to analyze clinical and histopathological findings of eccrine porocarcinoma. METHODS: We report nine cases of eccrine porocarcinoma that we have seen during last 10 years. RESULTS: Eccrine porocarcinoma affects elderly patients in both sexes and is usually found on the lower extremities, but in our review it is similar on the head. The mean size was 1.9 cm in our cases. Elective primary treatment was excision and we did not perform elective lymph node dissection. We have not found evidence of metastases in any of our cases.
