RESUMO

The clinical presentation of enteric duplication cysts is dependent on the location of the cyst with symptoms varying from nausea and vomiting to abdominal distension, pain and perforation. Four patients were identified who were diagnosed with enteric duplication cysts within the period from 2019 to 2023. Three of the patients presented with signs of intestinal obstruction-abdominal distension and pain, while one had an antenatally detected abdominal mass. There were three boys and one girl with ages ranging from 4 months to 14 years. Three cases of ileal and one case of caecal duplication cyst were reported. Most of the cases showed ileal/caecal mucosa while one case demonstrated ectopic gastric mucosa. The treatment of these cysts includes surgical excision. Although radiological investigations help in arriving at a provisional diagnosis, the final diagnosis can be confirmed only after histopathological examination. Early treatment prevents complications and results in a good prognosis for the patient. (AU)


La presentación clínica de los quistes de duplicación entérica depende de la ubicación del quiste, y los síntomas varían desde náuseas y vómitos hasta distensión abdominal, dolor y perforación. Se identificaron cuatro pacientes que fueron diagnosticados con quistes de duplicación entérica en el período de 2019 a 2023. Tres de los pacientes presentaron signos de obstrucción intestinal (distensión abdominal y dolor), mientras que uno tenía una masa abdominal detectada prenatalmente. Eran tres niños y una niña con edades comprendidas entre 4 meses y 14 años. Se notificaron tres casos de quiste de duplicación ileal y un caso de quiste de duplicación cecal. La mayoría de los casos mostraron mucosa ileal/cecal, mientras que un caso mostró mucosa gástrica ectópica. El tratamiento de estos quistes incluye la escisión quirúrgica. Aunque las investigaciones radiológicas ayudan a llegar a un diagnóstico provisional, el diagnóstico final solo puede confirmarse después del examen histopatológico. El tratamiento precoz previene complicaciones y redunda en un buen pronóstico para el paciente. (AU)

RESUMO

Epithelial inclusion cysts (EIC) are a rare ocular disease and its physiopathology is not well-known. They consist on growths of ocular surface epithelial cells inside the anterior segment of the eye in the form of a cyst. To date several cases have been published in the literature, none of them related to glaucoma surgery. We describe two cases of EIC after glaucoma devices implantation. An 86 year-old male patient with primary open angle glaucoma develop an EIC in right eye three years after removal of PRESERFLO™ MicroShunt (Santen, Osaka, Japan) and a 9 year-old female patient with glaucoma secondary to uveitis for juvenile idiopathic arthritis develops an EIC under the tube of an Ahmed valve implant during postoperative period. EIC develop after ocular penetrating wounds and an inflammatory stimulus. They are benign proliferations, follow-up is necessary to detect space complications early, so less mutilating surgery is needed for removal.

RESUMO

Extensive odontogenic cysts in children may represent surgical challenges, as they may have common clinical characteristics and different approaches. The main objective of this study is to compare two cases of pediatric odontogenic cysts in maxilla with similar surgical treatment and different histopathological diagnosis. The case series collected included two children, both 12 years old, with encapsulated osteolytic lesions in the region of the maxilla and zygoma body, with clinical and imaging characteristics that suggested odontogenic cysts. The histopathological diagnosis was dentigerous cyst and radicular cyst. In this way, we address the clinical-surgical diagnostic and therapeutic process adopted, analyzing clinical data, such as signs and symptoms, as well as pre- and postoperative tomography scans. Outpatient visits at regular intervals were planned. Both patients achieved significant regression of initial signs and symptoms and returned to their daily activities. It is noticeable that a good stratification of surgical need and planned action in diagnosis and surgery offer benefits with a favorable prognosis for pediatric odontogenic cysts of the jaw.


Los quistes odontogénicos extensos en niños pueden representar desafíos quirúrgicos, ya que pueden tener características clínicas comunes y diferentes abordajes. El objetivo principal de este estudio fue comparar dos casos de quistes odontogénicos en mandíbulas de niños con tratamiento quirúrgico similar y diagnóstico histopatológico diferente. La serie de casos recolectada incluyó dos niños, ambos de 12 años, con lesiones osteolíticas encapsuladas en la región mandibular y cuerpo cigomático, con características clínicas e imagenológicas que sugerían quistes odontógenos. El diagnóstico histopatológico fue quiste dentígero y quiste radicular. De esta manera abordamos el proceso diagnóstico y terapéutico clínico-quirúrgico adoptado, analizando datos clínicos, como signos y síntomas, así como tomografías pre y postoperatorias. Se planificaron visitas ambulatorias a intervalos regulares. Ambos pacientes lograron una regresión significativa de los signos y síntomas iniciales y regresaron a sus actividades diarias. Se destaca que una buena estratificación de la necesidad quirúrgica y una acción planificada en diagnóstico y cirugía ofrecen beneficios con un pronóstico favorable para los quistes odontogénicos de la mandíbula en pediatría.

RESUMO

RESUMEN La hidatidosis es una parasitosis endémica en la Argentina. Los órganos más afectados son hígado y pulmón, pero la afectación esplénica única es infrecuente. El objetivo del trabajo es presentar 2 casos de hidatidosis esplénica única. Su diagnóstico presuntivo se realizó mediante el antecedente epidemiológico y los estudios por imágenes. Las serologías resultaron negativas en ambos casos. El tratamiento fue quirúrgico: se realizó esplenectomía laparoscópica total. Esta patología debe sospecharse en zonas endémicas ante la aparición de quistes esplénicos a pesar de presentar serologías negativas. La esplenectomía total evita la recidiva local y cavidades residuales; se prefiere el abordaje laparoscópico al disminuir la estadía hospitalaria y las complicaciones de la pared abdominal.


ABSTRACT Hydatid disease is an endemic parasitosis in Argentina. The liver and lungs are the organs more commonly affected, but isolated splenic involvement is rare. The aim of this study is to report two cases of isolated splenic hydatid disease. The diagnosis was suspected by epidemiology and imaging tests. The serologic tests were negative in both cases. Surgical management was decided and both patients underwent laparoscopic total splenectomy. This disease should be suspected in endemic areas in the presence of splenic cysts despite negative serologic tests. Total splenectomy prevents local recurrence and complications associated with the residual cavity. The laparoscopic approach is preferred as it results in a shorter length of hospital stay and fewer abdominal wall complications.

RESUMO

Hilar cavernous transformation is the formation of venous structures rich in collateral around the portal vein. Portal vein thrombosis is a rare entity. Although there are many reasons for its etiology, few cases have been reported secondary to hydatid cysts in the liver. Here, we present a 24-year-old patient with complaints of abdominal pain and swelling. Her CT and MRI scans show cholelithiasis with portal vein thrombosis and hilar cavernous transformation due to giant hydatid cyst compression in the lateral liver sector.


La transformación cavernosa hiliar es la formación de estructuras venosas ricas en colaterales alrededor de la vena porta. La trombosis de la vena porta es una afección poco frecuente. Aunque existen muchas razones en su etiología, se han descrito pocos casos secundarios a quiste hidatídico en el hígado. Aquí se presenta el caso de una paciente de 24 años con quejas de dolor abdominal e hinchazón. La tomografía computarizada y la resonancia magnética mostraron colelitiasis con trombosis de la vena porta y transformación cavernosa hiliar por compresión del quiste hidatídico gigante en el sector lateral del hígado.

RESUMO

An extremely rare complication of endoscopic colloid cyst removal is presented. Terson's syndrome related to endoscopic resection of a colloid cyst has been reported only twice before in the literature and it could be explained by intracranial hypertension related to rinsing during the procedure. The case is described and the complications in the neuroendoscopic removal of colloid cyst are reviewed from the literature.

RESUMO

Las estructuras quísticas son uno de los hallazgos más frecuentes en dermatopatología. Se trata de tumores quísticos y de pseudoquistes por acumulación de ciertas sustancias, por ejemplo, mucina. En una serie de dos artículos (de los cuales este es el primero) hemos revisado los principales tipos de quistes y pseudoquistes que pueden verse en la biopsia cutánea, examinando sus aspectos histopatológicos y los principales diagnósticos diferenciales. En esta primera parte, se abordan los quistes infundibulares, dermoides, vellosos eruptivos, foliculares pigmentados, pilonidales, tricolemales, de milium, híbridos y broncogénicos, así como el esteatocistoma, el hidrocistoma y los comedones. (AU)


Cystic structures represent one of the most common findings in dermatopathology. These encompass both cystic tumors and pseudocysts resulting from the accumulation of certain substances, such as mucin. In a two-part series (of which this is the first part), we have reviewed the principal types of cysts and pseudocysts that may be observed in cutaneous biopsies, examining their histopathological features and primary differential diagnoses. This first part encompasses infundibular cysts, eruptive dermoid cysts, pigmented follicular cysts, pilonidal cysts, tricholemmal cysts, milium cysts, hybrid cysts, bronchogenic cysts, as well as steatocystoma, hydrocystoma, and comedones.

RESUMO

La hidatidosis es una zoonosis poco frecuente causada por cestodos del género Echinococcus. El órgano afectado con mayor frecuencia es el hígado, seguido del pulmón. La hidatidosis pulmonar se caracteriza por cursar de forma asintomática en la mayoría de los casos, y en muchas ocasiones suele ser un hallazgo casual en estudios realizados con otros fines. El diagnóstico resulta complejo por la diversidad de la presentación clínica, las pruebas serológicas pueden resultar negativas y los hallazgos de laboratorio son inespecíficos, por lo que debería ser un diagnóstico a tener en cuenta sobre todo en zonas con alta prevalencia de esta infestación. (AU)


Hydatidosis is a rare zoonosis caused by cestodes of the genus Echinococcus. The most frequently affected organ is the liver, followed by the lung. Pulmonary hydatidosis is characterized by an asymptomatic course in most cases, and in many cases it is usually an incidental finding in studies performed for other purposes. The diagnosis is complex due to the diversity of the clinical presentation, serological tests can be negative and laboratory findings are nonspecific, so it should be a diagnosis to consider especially in areas with high prevalence of this infestation.

RESUMO

El mesiodens es el diente supernumerario que se origina en la premaxila, siendo considerado el más prevalente o el más diagnosticado debido a las numerosas alteraciones que producen y que incluyen malposición de los dientes permanentes, formación de diastemas, retraso en la erupción de los incisivos anteriores superiores, y formación de quistes. La etiología de los mesiodens no está completamente comprendida, aunque se piensa que pueda deberse a la proliferación de la lámina dental u otros factores genéticos. El diagnóstico generalmente es tardío debido a que la mayoría permanece sin erupcionar, pudiendo generar complicaciones dentomaxilares que finalmente son el motivo de consulta de los pacientes. El quiste dentígero es un quiste odontogénico del desarrollo asociado a la corona de un diente incluido, numerario o supernumerario y su tratamiento es quirúrgico. El diagnóstico temprano y la planificación del tratamiento debe considerar una anamnesis minuciosa, un examen clínico e imágenes 3D. La cirugía debe consistir en la desinclusión del diente causal, la exéresis y legrado de la lesión, con o sin regeneración ósea inmediata del lecho quirúrgico con injerto. Se presentan dos casos de quiste dentígero asociado a un mesiodens que se diagnosticaron como hallazgo radiográfico. El plan de tratamiento consistió en evaluación y tratamiento endodóntico de los dientes desvitalizados, enucleción y legrado del quiste, junto a la desinclu sión del diente supernumerario, y seguimiento clínico y radiográfico en el largo plazo.


Mesiodens is the supernumerary tooth that originates in the premaxilla, considered the most prevalent or, the most diagnosed due to the multiple alterations that produce and that include malposition of the permanent teeth, formation of gaps, delayed eruption of the upper anterior incisors and cyst formation. The etiology of mesiodens is not fully established, although it is thought that it may be due dental lamina alteration or other genetic factors. Diagnosis is usually late because most remain unerupted, and can generate dentomaxillary complications that are ultimately the reason for patient consultation. The dentigerous cyst is a developmental odontogenic cyst associated with the crown of an included, numerary or supernumerary tooth and its treatment is surgery. Early diagnosis and treatment planning should consider a careful history, clinical examination, and 3D imaging. The surgery must consist of the disinclusion of the offending tooth, the exeresis and curettage of the lesion, with or without immediate bone regeneration of the surgical bed with a graft. Two cases of a dentigerous cyst associated with a mesiodens that were diagnosed as a radiographic finding are presented. The treatment plan consisted in evaluation and endodontic treatment of devitalized teeth, enucleation and curettage of the cyst, together with the disinclusion of the supernumerary tooth, and long-term clinical and radiographic follow-up.

RESUMO

The glandular odontogenic cyst (GOC) is a pathological entity that most commonly develops in the anterior region of the mandible and can emulate other lesions, including other cysts, odontogenic tumors, and even malignant lesions of glandular origin. Therefore, the aim of this manuscript is to report a new case of GOC treated conservatively and to discuss its clinical, radiological, histopathological, and therapeutic aspects.


El quiste odontogénico glandular (QOG) es una entidad patológica que se desarrolla con mayor frecuencia en la región anterior de la mandíbula y que puede mimetizar otras lesiones incluyendo otros quistes, tumores odontogénicos y hasta lesiones malignas de origen glandular. Por lo tanto, el objetivo del presente manuscrito es reportar un nuevo caso de QOG tratado de forma conservadora y discutir sus aspectos clínicos, imagenológicos, anatomopatológicos y terapéuticos.

RESUMO

INTRODUCTION AND OBJECTIVES: Nasal dermoids are uncommon midline congenital lesions in the nose, usually diagnosed in the first years of life. Imaging is mandatory to evaluate local and intracranial extension and treatment consists in surgical excision. This study aims to review the experience of the department in managing pediatric nasal dermoids using a dorsal rhinotomy surgical approach. MATERIAL AND METHODS: Retrospective case series of pediatric nasal dermoids treated at a tertiary university teaching hospital over a period of seven years. RESULTS: Nine children were treated during this period. Clinical presentation was a dermoid sinus-cyst in seven cases and a cystic lesion in two. Pre-operative imaging revealed extension of the lesion to the foramen cecum in three cases. Surgery was performed via vertical dorsal rhinotomy in all patients, and associated endoscopic surgery was used in three patients. Reconstruction with autologous material was performed in three cases. No complications or recurrences were registered during the follow-up. CONCLUSIONS: In the presented series, a vertical dorsal rhinotomy incision has provided good functional and aesthetic results. The possibility of nasal dermoid intracranial extension should be accessed with imaging but remains uncommon. In its absence, this approach may be useful and can be paired with other techniques, such as nasal endoscopy, to achieve the best outcomes.

RESUMO

Introducción: El quiste pilonidal es una condición crónica inflamatoria de la piel y el tejido subcutáneo sacrocoxígeo, con alta incidencia en jóvenes y sexo masculino. El manejo quirúrgico incluye técnicas abiertas y cerradas que utilizan colgajos. El objetivo es describir las características clínicas y quirúrgicas de pacientes operados de quiste pilonidal con técnica abiertas. Material y Método: Estudio tipo cohorte, retrospectivo, observacional y transversal. Se incluyeron todos los pacientes operados por quiste pilonidal utilizando técnicas abiertas en el Hospital Clínico de la Universidad de Chile entre 2013 y 2019. Se recolectaron características clínicas y quirúrgicas como tipo de técnica abierta, tiempo operatorio, tiempo de curaciones y cierre definitivo. Se aplicó estadística descriptiva. Resultados: Se registraron 250 pacientes diagnosticados de quiste pilonidal desde 2013, de los cuales se incluyeron 84,8% pacientes manejados con técnicas abiertas. 60,8% fueron de sexo masculino. El IMC promedio fue de 26,8 con un 24,5% de pacientes con obesidad. De ellos, 55,3% habían sido drenados en urgencias previamente y 9,6% eran recidivas. El tamaño promedio fue de 3,6 cm. Las técnicas abiertas empleadas fueron: marsupialización, destechamiento y McFee. El tiempo promedio de curaciones fue de 5,9 semanas y el cierre definitivo ocurre en promedio a las 10,4 semanas; 4,7% recidivaron. Conclusión. La cirugía del quiste pilonidal en nuestra serie corresponde en su mayoría a técnicas abiertas (marsupialización y destechamiento). El tiempo de curaciones, de cierre de la herida y del porcentaje de recidivas de los pacientes operados de quiste pilonidal es similar a lo reportado internacionalmente.


Introduction: The pilonidal cyst is a chronic inflammatory condition of the skin and subcutaneous sacrocoxige tissue, with high incidence in young people and male sex. Surgical management includes open and closed techniques which use flaps. The objective is to describe the clinical and surgical characteristics of patients operated on for pilonidal cyst with open technique. Material and Method: Cohort, retrospective, observational and cross-sectional study. We included all patients operated on for pilonidal cyst using open techniques at the Hospital Clinic University of Chile between 2013 and 2019. Clinical and surgical characteristics was collected, such as type of open technique, operative time, healing time and definitive closure. Descriptive statistics were applied. Results: There were 250 patients diagnosed with pilonidal cyst since 2013, of which 84.8% were patients managed with open techniques; 60.8% were male. The average BMI was 26.8 with 24.5% of patients with obesity. 55.3% had been drained in the emergency room previously and 9.6% were relapses. The average size was 3.6 cm. The open techniques used were marsupialization, unroofing and McFee. The average healing time was 5.9 weeks and definitive closure occurs on average at 10.4 weeks; 4.7% relapsed. Conclusion: Surgery of the pilonidal cyst in our series corresponds mostly to open techniques (marsupialization and unroofing). The healing time, wound closure and the percentage of recurrences of patients operated on for pilonidal cyst is similar to that reported internationally.

RESUMO

Introducción: La glándula tiroides tiene su origen embriológico en la base de la lengua, desde donde desciende al cuello. Este proceso migratorio puede detenerse o continuar más allá, dando diferentes cuadros de tiroides ectópica. El quiste tirogloso es la alteración embriológica más frecuente en el cuello, pudiendo desarrollar cáncer como una complicación rara. Caso clínico: Paciente de 21 años con aumento de volumen cervical, se diagnostica quiste tirogloso, la biopsia identifica cáncer papilar en el quiste. Se decide completar tiroidectomía, se objetiva agenesia de glándula. Ante respuesta bioquímica incompleta se realiza cintigrama que identifica nódulo retrolingual, el cual es resecado. Discusión: La resección del quiste tirogloso se debe realizar según la descripción de Sistrunk para evitar recidivas. La historia natural del cáncer en quiste tirogloso es bastante menos conocida y podría tener un peor pronóstico que el cáncer tiroideo habitual. Existen grupos que defienden la necesidad de completar tiroidectomía y, eventualmente, realizar disecciones cervicales como parte de su manejo. Conclusión: El cáncer de quiste tirogloso es una patología infrecuente, Existen diferentes lineas de manejo que se discuten en la literatura. Aún el análisis individualizado de los pacientes en comités multidisciplinario de expertos es la conducta sugerida.


Introduction: The thyroid gland has its embryological origin from the base of the tongue, where it descends to the neck. This migratory process can stop early or continue beyond, giving rise to differents cases of ectopic thyroid. The thyroglossal cyst is the most frequent embryological alteration in the neck, and it can develop cancer as a rare complication. Clinical case: A 21 year old patient with a cervical volume increase is diagnosed a thyroglossal cyst. Biopsy identifies papilary cancer in the cyst. It is decided to complete de thyroidectomy, and agenesis of the gland is observed. Due to incomplete biochemical response, a scintigram is performed, wich identifies a retrolingual nodule that is resected. Discussion: The resection of the thyroglossus cyst should be performed according to the description of Sistrunk to avoid recurrence. The natural history of cancer in the thyroglossal cyst is much less known and could have a worst prognosis than usual thyroid cancer. Some groups advocate for the need to complete a thyroidectomy and eventually perform cervical dissections as part of its management. Conclusion: The cancer on a thyroglossal cyst is a rare pathology. There are diferents management approaches that are discussed in the literature. However, an individualized analysis of patients in multidisciplinary expert committees it still the suggested aproach.

RESUMO

Introducción: La intervención de Sistrunk es el gold-standard en el tratamiento del quiste tirogloso pese a su imprecisión en cuanto a la disección suprahioidea. Tras su descripción en 2014, las modificaciones introducidas por Koempel, han permitido un abordaje suprahioideo más reproducible. Presentamos nuestra experiencia inicial con esta técnica. Métodos: Estudio retrospectivo de los pacientes con quiste tirogloso intervenidos mediante técnica de Koempel en nuestro centro en el periodo 2021-2022, recogiéndose datos demográficos, clínicos e histológicos. Resultados. Durante el periodo de estudio se intervinieron 5 pacientes (3 mujeres/2 varones), con una mediana de edad y peso de 5 años (2-6) y 16 kg (14-25) respectivamente. Todos los casos habían sufrido infecciones previas presentando fistulización cutánea el 60%. En 2 de los pacientes se indicó la cirugía por recidiva tras intervención de Sistrunk. La mediana del tiempo quirúrgico fue de 77minutos (57-110) identificándose el plano del músculo geniogloso en los 5 pacientes. No hubo complicaciones inmediatas y el diagnóstico de quiste tirogloso se confirmó histológicamente en todos los casos. Uno de los pacientes del grupo con recidiva previa, presentó recidiva tras la intervención, siendo esta subclínica y diagnosticada incidentalmente tras ecografía de control. El resto de los pacientes no presentó ninguna recurrencia tras un seguimiento mediana de 8 meses (1-12). Conclusiones: La técnica de Koempel permite un abordaje seguro y reproducible del segmento suprahioideo siendo una opción atractiva en casos complicados por infección o recidiva previa.(AU)


Introduction: In spite of being inaccurate in terms of suprahyoid dissection, Sistrunk’s procedure is the gold-standard technique in the treatment of thyroglossal cyst. Since it was first described in 2014, the modifications introduced by Koempel have allowed for a more reproducible suprahyoid approach. We present our initial experience with this technique.Methods: A retrospective study of patients with thyroglossal cyst undergoing Koempel’s technique in our institution from 2021 to 2022 was carried out. Demographic, clinical, and histological data was collected. Results. In the study period, 5 patients –3 girls and 2 boys– underwent surgery. Median age and weight were 5 years (2-6) and 16 kg (14-25), respectively. All patients had suffered from previous infections, with 60% having cutaneous fistulization. In 2 patients, surgery was indicated following Sistrunk’s procedure as a result of recurrence. Median operating time was 77 minutes (57-110), with the genioglossal muscle plane being identified in the 5 patients. No immediate complications were recorded, and diagnosis of thyroglossal cyst was histologically confirmed in all cases. One of the formerly recurrent patients had recurrence following surgery, but it was subclinical and incidentally diagnosed at control ultrasonography. The remaining patients had no recurrences after a median 8-month (1-12) follow-up period. Conclusions: Koempel’s technique allows for a safe and reproducible approach of the suprahyoid segment. It is an attractive option in complicated cases as a result of previous infection or recurrence.(AU)

RESUMO

Introducción: El tratamiento de los quistes hepáticos requiere del diagnóstico diferencial de quiste simple hepático (QSH) de la neoplasia mucinosa quística (NMQ) hepática. Las características radiológicas no son patognomónicas. Algunos estudios han sugerido la utilidad de los marcadores tumorales (MKT) intraquísticos. Métodos: Análisis retrospectivo de base de datos prospectiva incluyendo pacientes diagnosticados de QSH sintomático desde el 2003 hasta el 2021. El objetivo del estudio es evaluar los resultados del tratamiento de los QSH sintomáticos y analizar la utilidad de la determinación de «carcinoembryonic antigen» (CEA) y «carbohydrate antigen» CA 19.9 intraquísticos. Resultados: Se incluyeron 50 pacientes tratados por quiste sintomático. En 15 pacientes el primer tratamiento fue el drenaje percutáneo. En 35 pacientes se realizó fenestración laparoscópica. Cuatro pacientes se diagnosticaron de lesiones premalignas/malignas (NMQ, NPIB, linfoma B); tres de ellos requirieron una segunda cirugía tras la fenestración y el diagnóstico anatomopatológico. La mediana de los valores de CEA y CA- 19.9 fue de 196μg/L y 227.321U/mL respectivamente. Los pacientes con lesiones premalignas no tuvieron valores elevados de MKT. El valor predictivo positivo fue del 0% en ambos MKT, y el valor predictivo negativo fue de 89% y 91% respectivamente. Conclusiones: Los valores de CEA y CA 19.9 intraquísticos no permiten distinguir los QSH de las NMH. El tratamiento más resolutivo de los QSH sintomáticos es la fenestración quirúrgica. El análisis anatomopatológico de la pared del quiste posibilita su correcto diagnóstico, permitiendo indicar una reintervención quirúrgica en los casos de NMQ.(AU)


Introduction: To decide treatment of hepatic cysts diagnosis between simple hepatic cyst (SHC) and cystic mucinous neoplasm (CMN). Radiological features are not pathognomonic. Some studies have suggested the utility of intracystic tumor markers. Methods: Retrospective analysis of our prospective database including patients treated due to symptomatic SHC from 2003 to 2021. The aim of the study was to evaluate the results of treatment of symptomatic SHC and the usefulness of the determination of intracystic “carcinoembryonic antigen” (CEA) and “carbohydrate antigen” CA 19.9. Results: Fifty patients diagnosed and treated for symptomatic SHC were included. In 15 patients the first treatment was percutaneous drainage. In 35 patients the first treatment was laparoscopic fenestration. Four patients were diagnosed of premalignant or malignant liver cystic lesions (MCN, IPMN, and lymphoma B); three of them required surgery after initial fenestration and pathological diagnosis. Median CEA and CA 19.9 were 196μg/L and 227.321U/mL, respectively. Patients with malignant or premalignant pathology did not have higher levels of intracystic tumor markers. Positive predictive value was 0% for both markers, and negative predictive value was 89% and 91%, respectively. Conclusion: Values of intracystic tumor markers CEA and CA 19.9 do not allow distinguishing simple cysts from cystic liver neoplasms. The most effective treatment for symptomatic simple liver cysts is surgical fenestration. The pathological analysis of the wall of the cysts enables the correct diagnosis, allowing to indicate a surgical reintervention in cases of hepatic cyst neoplasia.(AU)

RESUMO

Cystic structures represent one of the most common findings in dermatopathology. These encompass both cystic tumors and pseudocysts resulting from the accumulation of certain substances, such as mucin. In a two-part series (of which this is the first part), we have reviewed the principal types of cysts and pseudocysts that may be observed in cutaneous biopsies, examining their histopathological features and primary differential diagnoses. This first part encompasses infundibular cysts, eruptive dermoid cysts, pigmented follicular cysts, pilonidal cysts, tricholemmal cysts, milium cysts, hybrid cysts, bronchogenic cysts, as well as steatocystoma, hydrocystoma, and comedones.
