ABSTRACT

Epidermoid cyst is a type of cutaneous cyst commonly found in daily practice. The facial area is the most common area for emergence of this benign condition. Simple extirpation is usually performed to remove epidermoid cysts. However, in rare cases, epidermoid cysts can evolve into malignancies such as basal cell carcinoma (BCC) or can mimic them, which adds difficulty when making a proper diagnosis. In cases of doubt, histopathology plays a key role in aiding diagnosis. This case report is about a 33-year-old woman with suspected nodular lesion that mimicked BCC, but after histopathological analysis was confirmed to be epidermoid cyst


El quiste epidermoide es un tipo de quiste cutáneo que se encuentra frecuentemente en la práctica diaria. El área facial es el área más común para la aparición de esta lesión benigna. La extirpación quirúrgica simple es el procedimiento habitual para eliminar los quistes epidermoides. Sin embargo, en casos raros, los quistes epidermoides pueden evolucionar en neoplasias malignas como el carcinoma basocelular (CCB) o pueden imitarlos, lo que añade dificultad al hacer un diagnóstico adecuado. En caso de duda, la histopatología desempeña un papel clave en la ayuda al diagnóstico. Este informe de caso trata sobre una mujer de 33 años con sospecha de lesión nodular que imitaba el CCB, pero después de que se confirmó con el análisis histopatológico, que se trataba de un quiste epidermoide.

ABSTRACT

El esteatocistoma es un hamartoma quístico de la porción media de las unidades folículo sebáceas que afecta principalmente el ducto sebáceo. Comúnmente se encuentra de manera múltiple y se transmite en forma autosómica dominante; en algunos casos se presenta en un contexto no familiar y en otros puede ser solitario. La primera descripción del esteatocistoma múltiple (EM) muy probablemente corresponde a Jamieson en 1873. La forma solitaria de esteatocistoma fue descrito por primera vez en 1982 por Brownstein y existen pocos casos descritos en la literatura Presentamos un caso clínico de paciente varón joven con tumoración solitaria en cuero cabelludo que fue extirpado cuyo resultado histopatológico fue de esteatocistoma solitario.


Steatocystoma is a cystic hamartoma of the middle portion of the sebaceous follicular units that mainly affects the sebaceous duct. It commonly presents in multiple forms and is transmitted in an autosomal dominant manner; in some cases, it occurs in a non-familial context and in others it may be solitary. The first description of steatocystoma multiplex (MS) is most likely by Jamieson in 1873. The solitary form of steatocystoma was first described in 1982 by Brownstein and there are few cases described in the literature. We present a clinical case of a young male patient with a solitary tumor on the scalp that was excised and whose histopathological result was solitary steatocystoma.

ABSTRACT

RESUMEN Los quistes epidermoides constituyen el 1 % de los tumores intracraneales y el 7 % de los del ángulo pontocerebeloso. Los colesteatomas son lesiones benignas que se originan de restos de tejidos epitelial ectodérmicos que quedan en el sistema nervioso central, al cerrarse el tubo neural entre la tercera y quinta semana de gestación. Se trata de un paciente remitido de la Consulta de Neurooftalmología con crisis de cefalea y toma de los pares craneales III, IV, V, rama oftálmica desde hace 2 semanas. Se le realizaron estudios imagenológicos donde se constató un tumor hipodenso en región silviana frontotemporal izquierdo. Se interpretó como un quiste arcnoideo. Se le aplicó un bordaje pterional transilviano con apoyo neuroendoscópico y para sorpresa del equipo quirúrgico se abordó un tumor perlado solido identificado macroscópicamente como un colesteatoma silviano. Se resecó la totalidad del tumor cerebral.


ABSTRACT Epidermal inclusion cysts constitute 1% of the intracranial tumors and 7% of the cerebellopontine angle ones.Cholesteatoma are benign lesions originated from the remains of ectodermic epithelial tissues remaining in the central nervous system when the neural tube closes between the third and fifth week of pregnancy. The case deals with a patient remitted from the Neurophthalmologic Consultation with migraine crisis and lesion on the III, IV, V cranial nerves, ophthalmologic branch, for two weeks. Image studies were carried out, showing a hypo dense tumor in the left silvian frontotemporal region. It was taken as an arachnoid cyst. A pterional trans-silvian approach with neuroendoscopic support was applied, and the surgical team was surprised when they found a solid pearly tumor that was macroscopically identified as a silvian cholesteatoma. The cerebral tumor was totally resected.

ABSTRACT

Los quistes epidermoides localizados en cabeza y cuello son poco comunes y pueden ser difíciles de diagnosticar. Se describen los casos de cuatro pacientes con quistes epidermoides de cabeza y cuello, dos con localización en la región sublingual y extensión suprahioidea, otro localizado en la pared orofaríngea posterolateral y otro en la región submaxilar y submentoniana. Fueron tratados con éxito mediante abordajes transorales y transcervical, respectivamente. Se realizó una revisión de la bibliografía y se describieron las características anatómicas, clínicas e histológicas y el tratamiento de estas infrecuentes lesiones. (AU)


Epidermoid cysts of the head and neck are rare and can be difficult to diagnose. Two cases of patients with epidermoid cysts of the floor of the mouth with suprahyoid extension, other located at posterolateral oropharynx wall andother located at the submandibular and submental space with extention to midline are described. They were successfully treated by a transoral and transcervical approach respectively. A review of the literature was performed, and the anatomical, clinical and histological aspects and treatment of these uncommon tumors were reported. (AU)

ABSTRACT

Los quistes esplénicos gigantes y no parasitarios son infrecuentes. Estas lesiones pueden manifestarse como dolor abdominal, si bien a menudo son asintomáticas y se diagnostican en forma incidental. Objetivo: Presentar el caso de un quiste esplénico epitelial gigante por su interés en la toma de decisiones diagnósticas y terapéuticas, al ser una entidad muy poco frecuente.
 Caso clínico: Paciente de sexo femenino de 13 años de edad que consultó por dolor abdominal de dos meses de evolución. En la exploración física se palpaba una masa de consistencia dura en hemiabdomen izquierdo. En los estudios de imágenes se visualizó una masa esplénica quística gigante. Se realizó esplenectomía obteniendo un quiste subcapsular que comprometía la mayor parte del bazo, el estudio anatomopatológico e inmunohistoquímico fueron compatible con quiste epitelial. La evolución postoperatoria y el posterior seguimiento ambulatorio fueron favorables. Conclusiones: El tratamiento de los quiste esplénicos gigantes no parasitarios es quirúrgico, intentando conservar, en lo posible, la mayor cantidad de tejido esplénico. Este procedimiento debe ser individualizado, considerando el tamaño, las posibilidades diagnósticas, el tejido esplénico residual, la edad del paciente y comorbilidades.


Giant nonparasitic splenic epidermoid cysts are relatively uncommon. These lesions can lead abdominal pain, but most of then are asymptomatic, and they are discovered incidentally. We report a 13-y old female with a giant splenic epidermoid cystic, given the special interest of diagnostic and therapeutic decision-making of this rare entity. Case report: A 13-y old female with clinical history of abdominal pain since the last two months. On physical examination a firm, tender mass was palpable in left hypochondrium. Diagnosis of a large cystic splenic mass was made based on ultrasound and abdominal computed tomography scan. Splenectomy was performed, and histopathological-immunohistochemistry studies revealed findings suggestive of primary epithelial cyst. The post-operative clinical course was satisfactory and uneventful. Conclusions: Treatment of giant nonparasitic splenic cysts is surgical. Preserve splenic parenchyma must be the aim in an individualized decision-making. The different types of surgical modalities will be according to the diagnosis and clinical situation (cyst size, age, comorbidities).

ABSTRACT

El quiste epidermoide es una entidad dermatológica frecuente, siendo muy rara su ubicación en la cavidad oral, con una mayor prevalencia a nivel de la cavidad oral. Es considerada de etiología congénita, aunque se presenta predominantemente en adulto jóvenes. Generalmente son masas bien circunscritas, decrecimiento lento y asintomáticos, aunque los ubicados en la cavidad oral y orofaringe pueden provocar trastornos fonatorios, deglutorios y respiratorios. El diagnóstico es clínico, siendo el diagnóstico diferencial con los quistes dermoides y teratoides solo posible con el estudio histopatológico. El tratamiento es quirúrgico y elpronóstico favorable sin recidivas. Se presenta un caso de quiste epidermoide localizado en la úvula palatina, en un varón de 6 meses de vida, tratado quirúrgicamente, con la excéresis del tumor por un abordaje trasoral


The epidermoid cyst is a frequent dermatological entity, being very rare its location in theoral cavity, with a higher prevalence at the level of the floor of the oral cavity. It is considered of congenitaletiology, although it occurs predominantly in young adults. They are generally well circumscribed, slowgrowing and asymptomatic masses, although those located in the oral cavity and oropharynx can causephonatory, swallowing and respiratory disorders. The diagnosis is clinical, being the differential diagnosiswith the dermoid and teratoid cysts only possible with the histopathological study. The treatment is surgicaland the prognosis is favorable without relapses. We present a case of epidermoid cyst located in uvula, in amale of 6 months of life, treated surgically, with the tumor excision by a transoral approach

ABSTRACT

El quiste epidermoide es un quiste de tejido blando de origen ectodérmico que se encuentra con poca frecuencia en la cavidad oral. Clínicamente se caracteriza por ser una lesión asintomática, de larga evolución, recubierta con mucosa normal, y usualmente se diagnostica cuando el aumento de volumen genera molestias en el paciente. El tratamiento varía de acuerdo a su tamaño y localización anatómica. Presentamos el caso de una paciente de 29 años de edad con un quiste epidermoide de gran tamaño, en reloj de arena, del piso de boca. Se describen las características específicas histológicas y clínicas, y se discute la conducta terapéutica seguida.


The epidermoid cyst is a soft tissue cyst of ectodermal origin found infrequently in the oral cavity. Clinically, it is characterized by an asymptomatic lesion, of long evolution, covered with normal mucosa, and is usually diagnosed when the volume increases and generates patient discomfort. Treatment varies according to its size and anatomical location. We report the case of a 29 year old patient with a large, hourglass shaped, epidermoid cyst in the floor of the mouth. Specific histological and clinical characteristics are described and the therapeutic behavior followed is discussed.

ABSTRACT

Introducción: Un paciente con tumor epidermoides intracraneal extradural con presentación sincrónica con absceso cerebral, sin antecedentes de trauma craneal penetrante, no ha sido reportado con anterioridad en la revisión del tema realizada por los autores. Se presenta un caso con estas características y se exponen consideraciones sobre el diagnóstico y el tratamiento. Caso clínico: Paciente femenina, de 48 años de edad, con antecedentes de cefalea crónica y tumor craneal palpable en región frontal izquierda. Los estudios humorales fueron normales. La RNM craneal mostró dos imágenes en anillo yuxtapuestas, extra e intraaxial de forma respectiva. En la cirugía se encontró tumor perlado extradural sin evidencia a la inspección de tumor intradural, se comprobó en el examen histopatológico tumor epidermoides. En los controles imagenológicos posoperatorios se descubrió la persistencia de la lesión intraaxial, en anillo, frontal izquierda. Una segunda cirugía evidenció un absceso cerebral de ubicación subcortical y se efectuó la resección radical. La evolución fue favorable, sin secuelas después de cuatro meses de seguimiento. Conclusiones: Se reportó un caso infrecuente, donde se presentó de forma sincrónica un tumor epidermoides extradural frontal izquierdo y absceso cerebral frontal ipsilateral, sin relación de continuidad ni comunicación fistulosa demostrada en las neuroimágenes ni en la exploración quirúrgica.


Introduction: A patient with intracranial extradural epidermoid tumor with synchronous presentation with brain abscess and no history of penetrating head trauma, has not been previously reported in the revision of the subject made by the authors. A case with these characteristics is presented and also considerations about diagnosis and treatment. Case report: A 48-yearold female patient, with a history of chronic headache and cranial palpable tumor in left frontal region. Humoral studies were normal. Cranial MRI showed two juxtaposed, extra and intraaxial ring images. At surgery an extradural pearly tumor without evidence of intradural tumor on inspection was found, biopsy showed an epidermoid tumor. Persistence of intraaxial ring lesion in left frontal lobe was showed in postoperative imaging controls. A second surgery discovered a subcortical brain abscess and radical resection was done. Patient outcome has been without sequelae after four months of follow-up. Conclusions: An uncommon case where reported with extradural left frontal epidermoid tumor and ipsilateral frontal brain abscess synchronously presented, neither continuity nor fistulous communication were demonstrated on neuroimaging or surgical exploration.

ABSTRACT

As the skin is the largest and complex organ, a wide variety of tumourlike lesions are encountered in the clinical practice. The ability to properly diagnose & treat these common lesions & to distinguish them from malignant tumours is the vital skills for all clinicians. Objective: To analyse retrospectively tumourlike lesions of skin with respect to age, sex, clinical features and histopathological features in a tertiary referral centre in Maharashtra, India. Methods : The present study consisted of analysis of tumourlike lesions of skin received in the histopathology section of department of pathology over a period of 5 years that is from August 2005 to July 2010 .The material comprised of biopsies and excision specimens. The clinical and histopathological details were noted. The findings were compared with those reported by other authors. Results : One hundred and seventy five (175) cases of tumourlike lesions of skin were seen .These lesions presented as skin swellings or tumours. Maximum cases (34.8%) of tumourlike lesions occurred in fourth & fifth decades with male preponderance (1.35:1). The maximum number of cases was encountered in the head & neck region (63.4%). Their size ranged from 0.4 to 9 cms. Epidermal cyst was the commonest tumourlike lesion (59.4%) followed by dermoid cyst (13.1%).Other lesions were trichilemmal cyst, fibroepithelial polyp, keloid, hypertrophic scar and epidermal nevus. Conclusion : Tumourlike lesions are clinically diagnosed by their presentation. However, the histopathological examination confirms the clinical diagnosis. The pathologic evaluation of all tumourlike lesions is mandatory to avoid patient’s and family’s anxiety.

ABSTRACT

Two rare cases of intragonadal epidermoid inclusion cysts are described. Their etiology remains controversial and a possible hypothesis is monodermal abortive teratomas, with no mesodermal and endodermal components. As the ultrasound test results were inconclusive, it became difficult to rule out the possibility of neoplasm. Therefore, patients were submitted to radical therapy. The definitive diagnosis for both cases was provided by the anatomopathological examination.


Trata-se de dois casos raros de cistos de inclusão epidérmica intragonadais, cuja etiologia permanece controversa, sendo uma hipótese a de teratomas monodérmicos abortivos, sem componentes mesodérmicos e endodérmicos. Devido a resultados inespecíficos dos exames ultrassonográficos, torna-se difícil afastar a possibilidade de neoplasia e o tratamento padrão permanece sendo, portanto, a terapia radical. O diagnóstico definitivo, em ambos os casos, foi firmado pelo exame anatomopatológico.

ABSTRACT

Epidermoid cyst are benign lesions representing 0,3-1,5 percent of intracranial tumors. They originate from inclusions of epithelials cells during closure of neural tube. Symptoms result from compression of adjacent structures or rarely due to rupture causing Chemical meningitis. In this report, we present the case of a 34 years old male with history of ictal headache and meningeal signs. Brain CT showed hypodense suprasellar lesion with signs of rupture into the ventricular system. MRI showed a hypointense lesion on T1 and hyperintense on T2, suspecting epidermoid tumor. The Patient was operated and the sample demonstrated an epidermoid cyst. Spontaneous cyst rupture and spillage of the content into subarachnoid space or ventricles manifest as meningeal syndrome and cause high morbidity. Cyst rupture into de ventricle is infrequently described in literature.


Los quistes epidermoides son lesiones benignas en su mayoría, representando un 0,3 al 1,5 por ciento de los tumores intracraneanos y se originan por la inclusión de elementos epiteliales en el momento del cierre del tubo neural. Su presentación clínica está dada por compresión de estructuras adyacentes y con menor frecuencia secundaria a la rotura espontánea causando meningitis química. Se presenta el caso clínico de un paciente de 34 años de sexo masculino que debuta con un cuadro de cefalea ictal y signos de irritación meníngea. La Tomografía computada de cerebro muestra una lesión hipodensa supraselar con signos de rotura hacia el sistema ventricular. La Resonancia Nuclear Magnética muestra una lesión predominantemente hipointensa en T1 e hiperintensa en T2 planteándose entre los diagnósticos posibles un quiste epidermoide. El paciente es operado y la biopsia informa un quiste epidermoide. La rotura de los quistes epidermoide hacia el espacio subaracnoideo o al ventrículo ocurre de forma espontánea, presentándose clínicamente con un síndrome meníngeo y puede ser causa de gran morbilidad. La rotura hacia el ventrículo es una presentación clínica descrita con poca frecuencia en la literatura.

ABSTRACT

A hybrid cyst is a rare condition which includes any type of cyst arising from the various parts of the pilosebaceous unit. We report a case of hybrid cyst with infundibular, isthmic, and pilomatrical differentiation. A 12-year-old boy presented with a mass on the right cheek. The physical examination revealed an oval-shaped, dark-gray protruding mass with dimensions of 0.9 cm × 0.6 cm that was non-tender to palpation. The mass was totally excised. The diagnosis of a hybrid cyst was confirmed by histological evaluation. It was a well-encapsulated mass and showed combined histologic features of infundibular, isthmus, and pilomatrical differentiation. The hybrid cyst is a follicular cyst that includes two or more components of a cystic lesion arising from the pilosebaceous unit. Occasionally, there have been reports of hybrid cysts consisting of two components in differentiation, but those showing more than two components of differentiation have been extremely rare. The pathogenesis of this unusual disease is not yet known.

ABSTRACT

Epidermoid cysts of the central nervous system are uncommon conditions, which are frequently located in the cerebellopontine angle and around the pons. They are covered with keratinized squamous epithelium and keratin lamella, which give its contents a soft, white-pearly appearance. Epidermoid cysts are mostly originated from malformations, presumably associated with surface elements of the nervous system ectoderm during the closure of the neural groove or formation of secondary cerebral vesicles. The authors describe a case of epidermoid cyst in the posterior fossa causing hydrocephalus and review morphologic and diagnostic criteria of this lesion.


Os cistos epidermoides do sistema nervoso central (SNC) são condições incomuns, estando localizados mais frequentemente no ângulo pontocerebelar e ao redor da ponte. Eles são revestidos por epitélio escamoso queratinizado e lamelas de queratina, tornando seu conteúdo branco-perolado e pastoso. Os cistos epidermoides são, na maioria das vezes, originados de malformações, possivelmente associados ao entremeio de elementos superficiais do ectoderma do SNC durante o fechamento da placa neural, ou formação das vesículas cerebrais secundárias. Os autores descrevem um caso de cisto epidermoide da fossa posterior determinando hidrocefalia e revisam critérios morfológicos e diagnósticos dessa lesão.

ABSTRACT

Eccrine spiradenomas are rare, benign, cutaneous tumors that originate in the sweat glands. Eccrine spiradenomas in the breast are very rare and only a few cases have been reported. We report here on the case of a 47-year-old woman with superficial masses in the breast and these masses had gradually increased in size during follow-up. They were confirmed to be an eccrine spiradenoma on pathologic examination. There have been a few reports about the radiologic findings of eccrine spiradenomas of the breast. This is the first case of an eccrine spiradenoma in the breast that was characterized by multiple imaging modalities, including mammography, ultrasonography and MRI. The lesion in our patient was first diagnosed as an epidermal inclusion cyst based on the imaging findings and the mass's superficial location. Although the mammographic and ultrasonographic imaging findings of eccrine spiradenomas and epidermal inclusion cysts are similar, the MRI findings are different between epidermal inclusion cysts and eccrine spiradenomas. Eccrine spiradenomas should be considered in the differential diagnosis of cutaneous and subcutaneous lesions of the breast.
