RESUMO
Este es el segundo artículo de una serie de dos publicados en esta revista, en los que examinamos las características histopatológicas, así como el diagnóstico diferencial, de las principales entidades que se presentan en forma de estructuras quísticas y pseudoquísticas en la biopsia cutánea. En este segundo artículo, abordamos los quistes cutáneo ciliado, branquial, de Bartholino, onfalomesentérico, tímico, del conducto tirogloso, sinovial, y del rafe medio, así como el mucocele, el ganglión y los pseudoquistes auricular y mixoide digital. (AU)
This is the second article in a two-part series published in this journal, in which we examine the histopathological characteristics, as well as the differential diagnosis, of the main entities that present as cystic and pseudocystic structures in cutaneous biopsy. In this second article, we address ciliated cutaneous cysts, branchial cysts, Bartholin's cysts, omphalomesenteric cysts, thymic cysts, thyroglossal duct cysts, synovial cysts, and median raphe cysts, as well as mucocele, ganglion, and auricular and digital myxoid pseudocysts.

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.

Introducción: Quiste epidermoide de inclusión es una lesión dérmica benigna frecuente, predominante en hombres de 30-40 años, originada por secuestro de restos epidérmicos, oclusión pilosebácea o implantación traumática de elementos epiteliales en la dermis.Caso clínico: Paciente femenino de 75 años de edad la cual presenta tumoración perineal de 4 años de evolución, con aumento progresivo en el último año ocasionando disconfort. Resonancia magnética nuclear, muestra lesión quística. Escisión quirúrgica incluyendo capsula en su totalidad. Anatomía patológica, quiste de inclusión epidérmica. Control a los 6 meses sin evidencia de recidiva.Conclusión: El quiste epidérmico gigante de inclusión perineal es raro, por lo cual hay que descartar otras patologías similares. El tratamiento quirúrgico debe evitar la escisión fraccionada e incluir la capsula en forma completa, de lo contrario la recidiva es una constante.
Introduction: The epidermoid inclusion cyst is a frequent benign dermal lesion, predominantly in men aged 30-40, caused by sequestration of epidermal remains, pilosebaceous occlusion or traumatic implantation of epithelial elements in the dermis.Case report: A 75-year-old female patient who has 4 years of evolution perineal tumor with a progressive increase in size in the last year causing discomfort. MRI shows a cyst lesion. Surgical excision including capsule. Pathological anatomy, epidermoid inclusion cyst. Following at 6 months without evidence of recurrence.Conclusion: The giant epidermoid cyst of perineum is rare, therefore we must rule out other similar pathologies. Surgical treatment should avoid fractional excision and include the capsule completely, otherwise recurrence is a constant.
