Primary adrenal cyst Adrenal cyst is the commonest type of benign lesions of adrenal gland, althought is a very rare entity. Tipically, they are presented with abdominal pain or palpable mass, but nowdays they are detected most fre-cuently an imaging studies like incidentaloma. Adrenal Cyst have a broad differential diagnoses, rendering defi nitive diagnosis and subsequent management diffi cult. Are categorized into four subtypes: endothelial, pseudocyst, epithelial, and parasitic. This management paradigm may be summarized as: ruling out functional status of the cyst, evaluating chances of incidental malignancy by imaging, avoiding potential complications of surveillance (hemorrhage, infection), particularly in large cysts. A case of a patient with a left non-functioning adrenal cyst is reported, with abdominal pain. The diagnostic and therapeutic options are discussed and the literature is reviewed. Resumen Los quistes suprarrenales son las lesiones quísticas más frecuentes de la glándula suprarrenal, a pesar de que constituyen una rara entidad. Típicamente se presentan por un cuadro de dolor abdominal o masa palpable, pero en la actualidad se detectan cada vez con más frecuencia en estudios radiológicos como incidentalomas. Los quistes suprarrenales cuentan con amplios diagnósticos diferenciales, lo que hace un difícil diagnóstico defi nitivo y una difi cultad en el manejo posterior. Estos quistes se clasifi can en cuatro subtipos: endoteliales, pseudoquiste, epiteliales y parasitarios. El manejo de un quiste suprarrenal se puede resumir en tres pilares fundamentales: descartar el estado funcional del quiste, evaluación de eventual malignidad por imágenes, y evitar las posibles complicaciones (hemorragia, infección), sobre todo en los quistes de gran tamaño. Se presenta el caso de una paciente con quiste suprarrenal izquierdo no funcionante asociado a dolor abdominal. Se realiza revisión de la literatura y se plantean los distintos diagnósticos y alternativas terapéuticas. Palabras clave: Quiste suprarrenal primario, quiste hidatídico, incidentaloma suprarrenal.

Primary thyroid lymphoma. Report of four cases Primary thyroid lymphoma is uncommon and usually of non-Hodgkin type. We report four female patients with thyroid lymphoma. A 81 year-old patient that was operated and received three cycles of chemotherapy and was lost from follow up. A 16 yearold patient that is operated and received full chemotherapy and was discharged free of disease. A 80 year-old patient that was operated and died due to a multiple organ failure, 50 days after hospital admission and a 54 year-old female that was operated but rejected chemotherapy and was lost from follow up (Rev Méd Chile 2009; 137: 928-35).

Superficial dermatomycosis are prevalent pathologies in the medical field and their diagnosis is fundamentally clinical. Histopathology is not considered part of his study, however, the diagnosis is exceptionally obtained by biopsy, when dermatomycosis was not suspected. Unpublished retrospective work is carried out on patients who had the histopathological diagnosis of superficial dermatomycosis between the years 2000-2019 at the HCUCH, based on selection criteria, obtaining 19 patients, in which the following were analyzed: age, gender, clinical characteristics, location, presumptive diagnosis and mycological and histological examinations. He stressed, as was our hypothesis, that dermatomycosis was not clinically suspected, since the presumptive diagnoses were various dermatoses. The most suspected dermatosis was psoriasis, as a result that 57.8% of the dermatoses studied had erythematous scaly plaques on examination. Another relevant fact is that only 21% of the cases underwent a direct mycological prior to the biopsy, which was negative (‘’ false negative’’). It is concluded, then, that superficial dermatomycosis should be considered clinical simulators of other dermatoses, so clinical suspicion and support of mycological examination and fungal culture is essential.

RESUMENEl trombohematoma subcoriónico es una extravasación de sangre localizada en la placa coriónica, entre amnios y corion. Es muy infrecuente, el diagnóstico no es común, tiene alto riesgo perinatal y no hay casos comunicados en nuestro medio. Se presentan 12 casos de sospecha diagnóstica antenatal, confirmada en el examen histopatológico placentario. Se describe y discute el cuadro clínico, las complicaciones maternas y perinatales, el diagnóstico ultrasónico, el manejo y los resultados obtenidos. En nueve casos se identificó una fase latente con hematoma de tamaño estable, entre el inicio de los síntomas y el parto, que duró en promedio 7,3 semanas. En ocho casos la fase latente fue seguida por una fase activa con aumento del hematoma asociado al parto prematuro. Tres embarazadas presentaron patología médica compleja con una muerte materna. Seis casos hicieron anemia severa y tres patología miscelánea. Hubo ocho amenazas de parto prematuro con tocolisis, tres rotura prematura de membranas, una colestasis y una preeclampsia. Los partos fueron prematuros, dos de 36 y 33 semanas y diez menores a 32 semanas. Siete prematuros tuvieron peso inferior a 1000 gramos y seis hicieron restricción fetal grave, en percentil <5 de la curva de crecimiento. Hubo complicaciones neonatales relacionadas con prematurez, restricción y bajo peso, manejados con hospitalización prolongada con promedio de 74 días (rango: 6-298 días). Diez neonatos sobrevivieron; hubo un mortinato y un mortineonato. La sobrevida fué 83,3% y la mortalidad de 16,6% que se comparan favorablemente con las cifras comunicadas. PALABRAS CLAVES: Trombo, hematoma, corion, placenta SUMMARYSubchorial thrombohaematoma is caused by blood extravasations in the corionic plate, between amnion and chorion. It is a rare pathologic entity, that carries a high perinatal risk, which has not being published in our country up to now. We report 12 cases in which the diagnosis was suspected before birth, and confirmed in the placentary pathological examination. We describe the clinical presentation, fetal and maternal risks, ultrasonographic findings, treatment and clinical outcomes. In 9 patients a latent phase was identified with a stable size hematoma, which had a mean duration of 7.3 weeks. In 8 cases the latent phase was followed by an active phase, with increasing size of the hematoma associated with preterm labour. Three pregnant women had severe complications which caused one maternal death. Six had severe anemia and other three had minor complications. Eight had preterm labor symptoms which required tocolysis. Three had prelabour rupture of membranes, one cholestasis disease and preeclampsia. Preterm labours were at 36, 33 and other ten before 32 weeks of gestation. Seven preterm newborns weight less than 1000 grams and six had severe 329 REV CHIL OBSTET GINECOL 2010; 75(5): 329 -338
