RESUMO
Los quistes broncogénicos se originan de anomalías en el desarrollo del árbol traqueobronquial durante el periodo embrionario temprano. Su localización más frecuente es el mediastino posterior. Los quistes broncogénicos de localización retroperitoneal son raros y más todavía los intrapancreáticos.Presentamos un caso de un quiste broncogénico intrapancreático asintomático en un hombre de 61 años detectado casualmente en una revisión urológica.(AU)
Bronchogenic cysts arise from abnormalities of the tracheobronchial tree occurring during the early stages of embryonal development. They are most often found in the posterior mediastinum. Retroperitoneal bronchogenic cysts are infrequent and intrapancreatic bronchogenic cysts extremely rare. We present a case of an asymptomatic, intrapancreatic bronchogenic cyst which was an incidental finding during the urological workup of a 61-year-old man.(UA)

Deciduoid mesothelioma is an uncommon histological variant of epithelial mesothelioma which is extremely clinically aggressive. We report 3 cases of pleural caducoid mesothelioma in women of 75, 74 and 23 years of age. All patients presented with dyspnoea, vomiting and pelvic pain. Their imaging studies showed nodular pleuropericardic thickening, a parietal pleuropericardic solid mass and a large thoracic mass, respectively. Only one of them could be treated with chemotherapy, surgery and radiotherapy. Post diagnostic survival was 24 days, 1 month and 17 months respectively (mean 6.2 months). We describe the clinicopathological and immunohistochemical findings together with a review of the relevant literature.

La mucinosis nodular de la mama es una rara entidad de histogénesis incierta y con comportamiento benigno. Suele presentarse como una tumoración asintomática en torno a pezón o areola y localizada en dermis o tejido celular subcutáneo. Presentamos un caso de mucinosis nodular típica. Histológicamente se define por estar constituida por lagos irregulares de mucina negativos con PAS pero positivos con hierro coloidal y azul alcián. La mucina se acompaña de estroma fibroso con un escaso componente de células fusiformes. Algunos autores sugieren un posible origen miofibroblástico. No obstante no se han realizado estudios moleculares de la mucinosis nodular. El diagnóstico diferencial se ha de hacer principalmente con lesiones mamarias benignas y malignas de estroma mucinoso. En la literatura se describen 13 casos de mucinosis nodular
Nodular mucinosis of the breast is a rare entity of uncertain histogenesis and with benign behavior. It usually presents as an asymptomatic tumor around the nipple or areola and located in the dermis or subcutaneous cellular tissue. We present a case of typical nodular mucinosis. Histologically it is defined as being composed of irregular lakes of mucin negative with PAS but positive with colloidal iron and alcian blue. Mucin is accompanied by fibrous stroma with a scarce component of fusiform cells. Some authors suggest a possible myofibroblastic origin. However, molecular studies of nodular mucinosis have not been performed. The differential diagnosis must be made mainly with benign and malignant mammary lesions of mucinous stroma. In the literature, 13 cases of nodular mucinosis are described

La artritis reumatoide (AR) es una enfermedad autoinmune de causa desconocida y de evolución crónica que afecta fundamentalmente a las articulaciones provocando una sinovitis erosiva crónica y simétrica, presenta muchas complicaciones extraarticulares, siendo la patología pleural la complicación más frecuente entre las neumológicas. El síndrome de Contarini1 es una entidad infrecuente que consiste en la existencia concomitante de derrames pleurales bilaterales de diferente etiología. Presentamos el caso de un paciente en el que coincidieron ambas condiciones patológicas
