ABSTRACT

OBJETIVO: Los tumores triples negativos (TN) constituyen el subgrupo de cáncer de mama (CM) más agresivo. Nuestro objetivo es analizar los principales factores radiopatológicos de estos tumores para crear un perfil de riesgo. MATERIALES Y MÉTODOS: Es un estudio constituido por 140 pacientes diagnosticadas de CM TN desde enero del 2007 a diciembre del 2016. Se analizaron los factores radiológicos en resonancia magnética (RM) de estadificación: tamaño, necrosis, hallazgos asociados, adenopatías, parámetros de perfusión y difusión. En biopsias diagnósticas se estudiaron características del componente infiltrante: tipo histológico, Scarf-Bloom, Ki67 y p53 y el componente in situ. Se analizaron las adenopatías histológicamente positivas y en las piezas quirúrgicas: tamaño, invasión linfovascular/perineural y adenosis microglandular. El seguimiento finalizó en abril de 2018. Se evaluó la relación de los factores radiopatológicos con la recidiva y la supervivencia libre de enfermedad (SLE). RESULTADOS: Los tumores con tamaño igual o superior a 25 mm en RM, realce no nodular, edema mamario o retracción del complejo aréola-pezón y adenopatías presentaron más recidivas y menor SLE. Los carcinomas lobulillares infiltrantes, el tamaño posquirúrgico>20 mm y p53 <15% también se asociaron con la recidiva y una menor SLE. Las adenopatías histológicamente positivas se relacionaron con un mayor porcentaje de recidivas, y la invasión linfovascular, con una menor SLE. El análisis multivariante ha definido que el tamaño en RM>25 mm, el realce no nodular, las adenopatías en RM, y la expresión menor del 15% de p53 son variables pronósticas independientes. CONCLUSIONES: El tamaño igual o superior a 25 mm, realce no nodular y adenopatías en RM, y una expresión inferior al 15% de p53 condicionan una menor SLE


OBJECTIVE: Triple-negative tumors are the most aggressive type of breast cancer. We aimed to analyze the main radiologic and histopathologic factors of these tumors to create a risk profile. MATERIALS AND METHODS: We analyzed data from 140 patients diagnosed with triple-negative breast cancer between January 2007 and December 2016, with follow-up through April 2018. We analyzed the following variables in the breast MRI done for staging: size, necrosis, associated findings, adenopathies, and perfusion and diffusion parameters. We analyzed the following variables in histopathologic studies of biopsy specimens: histological type, Scarf-Bloom, Ki67, and p53 in the infiltrating component as well as in the in situ component. We analyzed the following variables in histopathologic studies of positive lymph nodes and surgical specimens: size, lymphovascular/perineural invasion, and microglandular adenosis. We analyzed the relation between the radiologic and histopathologic factors and recurrence and disease-free survival. RESULTS: MRI tumor size>25mm, non-nodular enhancement, breast edema, areola-nipple complex retraction, and lymph-node involvement were associated with recurrence and lower disease-free survival. Invasive lobular carcinoma, postsurgical size>20mm, and p53<15% were also associated with recurrence and lower disease-free survival. Histologically positive lymph nodes were associated with a greater percentage of recurrence and lymphovascular invasion and with lower disease-free survival. The multivariate analysis found that the variables MRI size>25mm, non-nodular enhancement, adenopathies on MRI, and p53 expression <15% were independent predictors of lower disease-free survival. CONCLUSIONS: In triple-negative breast tumors, factors associated with lower disease-free survival are non-nodular enhancement, size>25mm, and adenopathies on MRI, and p53 expression <15% on histopathologic study

ABSTRACT

Objetivo. Analizar la asociación entre la densidad mamográfica, la invasión linfovascular, la adenosis microglandular y el estado ganglionar de los tumores triples negativos (TN) con la recidiva tumoral y la supervivencia libre de enfermedad. Estudiar si la perfusión tumoral en las RM de estadificación se correlaciona con la recidiva tumoral, la supervivencia libre de enfermedad o los valores de restricción a la difusión. Analizar si la administración de quimioterapia neoadyuvante (QTN) o el tipo de tratamiento quirúrgico (cirugía conservadora o mastectomía) se asocian a un peor pronóstico. Pacientes y métodos. Estudio retrospectivo de las mamografías y de las RM pretratamiento de 122 pacientes con tumores TN entre los años 2007 y 2014. Se valoró la densidad mamaria en estudios mamográficos realizados en el momento del diagnóstico. El estado ganglionar se analizó en muestras de biopsia o quirúrgicas, mientras que la invasión linfovascular y la adenosis microglandular se estudió únicamente en muestras quirúrgicas. Resultados. La densidad mamográfica y los factores anatomo-patológicos no se asociaron con la recidiva tumoral. Los valores de realce máximo en la secuencia dinámica eran más altos en las pacientes sin recidiva tumoral (p=0,028), sin demostrar relación con la restricción a la difusión. Conclusiones. Los tumores con valores más altos de realce interno en RM de estadificación presentan un menor índice de recidivas. No se demostró correlación entre los valores de realce interno tumoral y de restricción a la difusión. Y no se observó asociación pronóstica con el resto de factores radio-patológicos (AU)


Objective. To analyse the association between breast density, lymphovascular invasion, microglandular adenosis and the axillary node status of triple-negative tumours (TN) with tumour recurrence and disease-free survival. To study whether tumour perfusion in MRI staging correlates with tumour recurrence, disease-free survival or diffusion restriction. To analyse whether the administration of neoadjuvant chemotherapy (NC) or the type of surgical treatment (breast-conserving surgery or mastectomy) are associated with a worse prognosis. Patients and methods. A retrospective study of mammograms and staging MRIs was performed from 2007 to 2014, including 122 women with TN breast cancer. Breast density was assessed in mammographic studies performed at the time of diagnosis. Lymph node status was analysed in biopsy or surgical specimens, whereas lymphovascular invasion and microglandular adenosis were studied only in surgical specimens. Results. Breast density and histopathological factors were not associated with tumour recurrence. The maximum enhancement values in the dynamic sequence were higher in patients without tumour recurrence (P=.028), without demonstrating a relationship with diffusion restriction. Conclusions. Tumours with higher values of internal enhancement showed less tumour recurrence. There was no correlation between the values of internal tumour enhancement and diffusion restriction. No prognostic association was observed with the remaining radiopathological factors (AU)

ABSTRACT

Objetivo. Analizar si la perfusión y restricción a la difusión de los tumores triple negativos en la resonancia magnética de estadificación se correlacionan con la respuesta a la quimioterapia neoadyuvante (QTN). Correlacionar la respuesta radiopatológica a la QTN y estudiar si el grado de respuesta asocia un peor pronóstico. Pacientes y métodos. Estudio retrospectivo de 73 pacientes con tumores triple negativos diagnosticados entre los años 2007 y 2014 con resonancia magnética de estadificación y de control posterior al tratamiento QTN. Se valoró el grado de respuesta radiológica al tratamiento QTN mediante resonancia magnética y la respuesta patológica en muestras quirúrgicas, siendo posible la correlación radiopatológica en 46 pacientes. Resultados. Se determinó moderada concordancia radiopatológica a la respuesta quimioterápica (kappa=0,590). Los tumores con un menor time to peak asociaban porcentajes mayores de respuesta radiológica completa (p=0,022) y los tumores con curvas funcionales tipo 3 se asociaban a mayores porcentajes de respuesta completa patológica (p=0,024). Se demostró menor supervivencia en las pacientes con menor respuesta radiológica (p=0,004) o patológica (p=0,04). No se encontró correlación entre los grupos de respuesta completa radiopatológica respecto al resto de grupos de respuesta y la supervivencia libre de enfermedad. Conclusiones. Los tumores triple negativos con menor time to peak o con curvas tipo 3 presentaban mejor respuesta al tratamiento. Se ha demostrado mayor supervivencia en tumores con mayor grado de respuesta radiopatológica (AU)


Objectives. To analyse whether perfusion and diffusion restriction in staging magnetic resonance imaging of triple-negative tumours correlate with response to neoadjuvant chemotherapy (NC). To correlate the radio-pathological chemotherapy response and determine whether the response is associated with a worse prognosis. Patients and methods. Retrospective study of 73 patients with triple-negative tumours diagnosed between 2007 and 2014 with staging magnetic resonance imaging and follow-up magnetic resonance imaging after NC treatment. The radiological response to NC treatment at magnetic resonance imaging and the pathological response in surgical specimens were assessed. Radio-pathological correlation was feasible in only 46 patients. Results. A moderate radiological-pathological concordance was found in relation to chemotherapy response (kappa=0.590). Tumours with lower time to peak of radiological complete response (P=.022) and tumours with functional type 3 curves were associated with higher percentages of pathological complete response (P=.024). Lower survival was demonstrated in patients with lower radiological (P=.004) or pathological (P=.04) response. No correlation was found between the complete radio-pathological response groups with respect to the rest of the response groups and disease-free survival. Conclusions. Triple-negative N tumours with lower time to peak or type 3 curves showed better response to treatment. Increased survival was found in tumours with a higher level of radio-pathological response (AU)

ABSTRACT

El sarcoma sinovial (SS) renal fue descrito por primera vez por Argani et al. en el año 2000. Presentamos un caso de SS renal monofásico de grado intermedio. Se trata de un varón de 42 años que presentaba un tumor renal sólido-quístico de 6 cm bien delimitado, con un nódulo sólido de 1,5 cm. Se realizó nefrectomía parcial. El tumor se caracterizaba por células fusiformes monomorfas y quistes revestidos por células epiteliales en tachuela. Se observó infiltración focal de la grasa perirrenal que rodeaba el nódulo sólido. Las células fusocelulares expresaban CD99, BCL2, EMA y SMA, y eran negativas para S-100, CD34, receptores de estrógenos y progesterona, desmina y WT1. Las células en tachuela expresaban CD10, PAX8, PAX2, EMA, CKAE1-AE3, CK7 y CK19, confirmando que eran epitelio renal atrapado. Se realizó FISH que demostró la translocación t(X;18), específica del SS. El paciente ha recibido 4 ciclos de quimioterapia adyuvante y continúa libre de recurrencia o metástasis 9 meses tras la intervención (AU)


Synovial sarcoma (SS) of the kidney was first reported by Argani et al. in 2000. We report a case of a renal monophasic SS of intermediate grade in 42-year-old man with a solid-cystic, well-circumscribed, 6 cm renal mass containing a solid nodule of 1.5 cm. Partial nephrectomy was performed. The tumour was characterized by monomorphic spindle cells and cysts lined by trapped «hobnail» epithelial cells. Sections showed focal infiltration of perinephric fat surrounding the solid nodule. Spindle cells expressed CD99, BCL2, EMA and SMA and were negative for S-100, CD34, oestrogen and progesterone receptors, desmin and WT1. The 'hobnail epithelium' expressed CD10, PAX8, PAX2, EMA, CKAE1-AE3, CK7 and CK19, confirming its non-neoplastic and renal identity. FISH was performed and t(X;18) translocation, specific of SS, was demonstrated. The patient received 4 cycles of adjuvant chemotherapy and is alive without evidence of disease 9 months after surgery (AU)

ABSTRACT

El porocarcinoma es un tumor maligno infrecuente, habitualmente originado sobre un poroma de larga evolución. Normalmente se localiza en extremidades inferiores, cabeza y cuello, en la sexta y séptima décadas de la vida. Debido a la escasa cantidad de casos documentados, realizamos un estudio retrospectivo durante 12 años consecutivos entre los diagnósticos registrados en la base de datos de nuestro Servicio de Anatomía Patológica. Recogimos 6 casos de dicho tumor sobre un total de unas 33.000 biopsias de piel, y analizamos sus características clínicas e histopatológicas. Observamos una incidencia 4 veces superior a la descrita en otros estudios, predominio en mujeres, y una media de edad y tamaño tumoral superiores. Su presentación clínica variada, larga evolución asintomática, y sus características arquitecturales, citológicas e inmunohistoquímicas, sí son concordantes con la literatura previa (AU)


Porocarcinoma is a rare malignant sweat gland tumour, usually developing from a long standing poroma. It is frequently found on the lower extremities or head and neck, and most cases occur in elderly patients. Due to the limited infrequency of documented cases, we performed a retrospective study over 12 consecutive years from the database of our department of pathology. We collected 6 cases of this tumour from a total of 33,000 skin biopsies and reviewed the main clinical and histopathological findings. In comparison to previous studies, we found a 4-times-higher incidence of porocarcinoma, female predominance, a higher average age and a larger tumour size. However, their diverse clinical presentation, longstanding asymptomatic evolution, morphological features and immunohistochemical profile are consistent with previous literature (AU)

ABSTRACT

Diagnosis of chronic myelomonocytic leukemia (CMML) is based on a combination of clinical, laboratory, and morphological parameters, including persistent peripheral blood monocytosis. Recently, mutations of serine/arginine-rich splicing factor 2 (SRSF2) have been identified in 40% to 50% of CMMLs and occasionally in other myeloid disorders. In this study, we established a robust assay for the detection of SRSF2 mutations in decalcified, paraffin-embedded bone marrow (BM) biopsies and investigated its diagnostic utility. BM biopsies of 78 patients with myeloid neoplasms, including 36 CMMLs, 22 myelodysplastic syndromes (MDS), and 20 Ph- myeloproliferative neoplasms (MPN) were analyzed. The region around hot spot P95 in exon 1 of SRSF2 was amplified and bidirectionally sequenced. In addition, a restriction fragment length polymorphism analysis was established. The JAK2 V617F mutation was investigated by allele-specific polymerase chain reaction. SRSF2 mutations were identified in 16 (44%) of 36 CMMLs, including 1 of 3 cases with associated systemic mastocytosis, 4 (20%) of 20 Ph- MPN, and 1 (4.5%) of 22 MDS. Restriction fragment length polymorphism analysis detected all mutations with the exception of a single P95A. Of note, 2 cases of JAK2 V617F+ primary myelofibrosis with SRSF2 mutation initially were diagnosed as CMML based on significant peripheral blood monocytosis. In CMML, no correlation with histopathology and/or clinical parameters was observed, but SRSF2 mutations were associated with normal karyotype (P < .001). In summary, SRSF2 mutations are frequent in CMML and a useful diagnostic feature demonstrable in BM biopsies, allowing a definitive diagnosis for cases with minimal dysplasia and normal karyotype. The role of SRSF2 mutations in cases with hybrid features between primary myelofibrosis and CMML needs further investigation.

ABSTRACT

El síndrome de Li Fraumeni (SLF) es una rara enfermedad hereditaria asociada con un riesgo incrementado de padecer ciertos tumores malignos. Presentamos el caso de una paciente con diagnóstico de SLF con antecedentes de sarcoma de glúteo con metástasis pulmonares y cáncer de mama bilateral metacrónico. Acudió al Servicio de Urgencias por distensión y dolor abdominal. Se objetivó una masa pélvica y se pensó en un probable origen ovárico de la misma. La paciente fue intervenida en el Servicio de Ginecología, y durante la intervención se descartó dicho origen ya que la tumoración dependía del epiplón. El diagnóstico final fue metástasis de sarcoma.


Li-Fraumeni syndrome (LFS) is a rare, inherited syndrome associated with increased risk of various malignant tumors. We present the case of a patient diagnosed LSF with a history of gluteal sarcoma with lung metastases and metachronous bilateral breast cáncer. She came to the emergency department for abdominal bloating and pain. She had a pelvic mass and we had thought probable ovarian dependence. The patient was operated on at the Department of Gynecology, and during the intervention we realized that the tumor depended on the omentum. The final diagnosis was a metastatic of sarcoma.

ABSTRACT

El tumor desmoplásico de células pequeñas y redondas es un tumor agresivo poco frecuente que surge generalmente en el peritoneo abdominal o pélvico. Afecta sobre todo a varones jóvenes y se caracteriza por la presencia de células pequeñas e indiferenciadas con núcleos hipercromáticos. Su principal característica diagnóstica es la co-expresión de marcadores epiteliales, musculares y neuronales, así como la presencia de la translocación recíproca t (11; 22)(p13; q12), que afecta a los genes EWS y WT1. Presentamos un caso de localización y clínica atípicas, con un perfil inmunohistoquímico peculiar y cuyo diagnóstico pudo ser filiado de forma concluyente tras realizar el estudio molecular. Se trata de una niña de 7 años con un tumor localizado en la pared torácica. Tras la cirugía se inicia tratamiento con quimioterapia. La paciente continúa viva a los 7 meses de la intervención (AU)


Desmoplastic small round cell tumour is a rare, aggressive neoplasm usually found in young males in the abdominal or pelvic peritoneum. It is characterized by the presence of small undifferentiated cells with hyperchromatic nuclei. Its main diagnostic feature is the co-expression of epithelial, muscular and neural markers in addition to the reciprocal translocation t (11; 22)(p13; q12), which affects the WT1 and EWS gene. We present a case of a 7 year old girl with a tumour in the thoracic wall. The unusual location, together with an atypical IHC profile meant that diagnosis was only possible after molecular studies. The patient underwent postoperative chemotherapy and is alive and well 7 months after surgery (AU)

ABSTRACT

La fibrosis hepática congénita (FHC) es una rara entidad congénita multisistémica, incluida en el grupo de las enfermedades fibropoliquísticas, que afecta principalmente al sistema hepatobiliar. Su forma de presentación suele ser poco específica y en ocasiones resulta muy difícil llegar a su correcto diagnóstico. Presentamos el caso de una paciente de 29 años de edad en estudio por hepatomegalia asintomática, aparentemente sin antecedentes clínicos de interés. Si bien el diagnóstico definitivo se realizó mediante una biopsia hepática, los hallazgos obtenidos con las técnicas de imagen pudieron ofrecer una adecuada aproximación al diagnóstico...
