Siringocistoadenoma papilífero: reporte de 11 casos del Hospital Clínico de la Universidad de Chile / Papilliferum Syringocystoadenoma: report of 11 cases of Clinical Hospital of the University of Chile

Introducción: El siringocistoadenoma papilífero (SP) es un tumor anexial benigno inusual, de etiología desconocida. Por lo general, se presenta desde el nacimiento, o en la primera infancia como una lesión aislada, frecuentemente asociada a un nevo sebáceo de Jadassohn. Objetivo: Describir y analizar las características demográficas, clínicas e histopatológicas del SP. Materiales y métodos: Revisión retrospectiva de informes histopatológicos del Departamento de Anatomía Patológica del Hospital Clínico de la Universidad de Chile entre los años 2005 y 2016. Se incluyeron todas las muestras que describieron dentro del diagnóstico histológico las palabras "siringocistoadenoma papilífero". Resultados: La muestra está compuesta por 11 pacientes; 9 mujeres y 2 hombres. En 5 pacientes, se desarrolló un SP a partir de un nevo sebáceo y en 6 surgió de novo. El total de la muestra desarrolló el SP durante o posterior a la pubertad. Tanto los pacientes con SP solitario, como aquellos asociados a un nevo sebáceo, presentaron clínica similar con una placa o pápula verrucosa aislada. Los principales diagnósticos diferenciales fueron el nevo sebáceo, nevo verrucoso y verruga. Conclusiones: Este estudio constituye la primera serie de casos de SP en un hospital en Santiago de Chile. La forma clínica más frecuente fue como placa verrucosa solitaria asintomática, con casos aislados como pápula verrucosa y sólo un caso con aspecto de cuerno cutáneo. Se destaca el rol de la extirpación quirúrgica completa, tanto para establecer el diagnóstico, como para ofrecer un tratamiento definitivo, disminuyendo el riesgo de transformación maligna a siringocistoadenocarcinoma papilífero.

Introduction: Syringocystoadenoma papilliferum (SCAP) is an unusual benign adnexal tumor of unknown etiology. Usually it is presented at birth or in early childhood as an isolated lesion associated with nevus sebaceous of Jadassohn. Objective: To describe and analyze the demographic, clinical and histopathological characteristics of SCAP. Materials and methods: A retrospective review of histopathological reports was performed at the Clinical Hospital´s Department of Pathological Anatomy from the University of Chile including biopsies from 2005 to 2016. All the samples that described the histological diagnosis of "syringocystoadenoma papilliferum" were included. Results: The sample consists of 11 patients; 9 women and 2 men. In 5 patients, an SCAP was developed from a sebaceous nevus and in 6 it developed de novo. The total sample developed SCAP during or after puberty. Both the patients with solitary SCAP, and those associated with nevo sebaceous, presented similar clinical signs with an isolated verrucous plaque or papule. The main differential diagnoses were the nevo sebaceous, warty nevus and wart. Conclusions: This study is the first SCAP case series in Santiago, Chile. The most frequent clinical form was an asymptomatic solitary verrucous plaque, with isolated cases as a verrucous papule and a single case as a cutaneous horn. The role of complete surgical resection is highlighted, both to establish the diagnosis and to offer a definitive treatment, reducing the risk of malignant transformation to syringocystadenocarcinoma papilliferum.

Abordagem de hidrocistomas palpebrais écrinos por incisão de blefaroplastia inferior / Excision of eyelid eccrine hidrocystomas via lower blepharoplasty incision

INTRODUÇÃO: O hidrocistoma palpebral écrino corresponde a lesão cística rara, usualmente de pequenas dimensões, não ultrapassando o diâmetro de 10 mm. Sua abordagem usualmente é por excisão simples e biópsia. É alto o índice de recidiva local. MÉTODOS: Paciente com múltiplos hidrocistomas bilaterais, vários maiores que 10 mm. Sob anestesia local, foi realizada incisão infraciliar tradicionalmente usada para blefaroplastia inferior e retirada dos hidrocistomas com cápsula íntegra. RESULTADOS: Paciente com excelentes resultados estéticos e sem recidivas até o presente momento, mais de seis meses após o procedimento. CONCLUSÃO: A incisão infraciliar de blefaroplastia inferior é uma técnica promissora para exérese de hidrocistomas maiores que 10 mm. Mais estudos devem ser realizados para confirmação do bom resultado estético-funcional desta técnica.

INTRODUCTION: Eccrine eyelid hidrocystoma is a rare cystic lesion, usually small and not exceeding 10 mm in diameter. Its treatment is usually by simple excision and biopsy. The rate of local recurrence is high. METHODS: A patient presented with multiple bilateral hidrocystomas, several larger than 10 mm. Under local anesthesia, an infraciliary incision traditionally used for lower blepharoplasty was performed, and hidrocystomas with intact capsules were withdrawn. RESULTS: The patient had excellent esthetic results, with no recurrence for more than six months after the procedure. CONCLUSION: The infraciliary lower blepharoplasty incision is a promising technique for excising hidrocystomas larger than 10 mm. More studies should be conducted to confirm the good esthetic and functional outcomes of this technique.

Clear Cell Hidradenoma of the Axilla: a Case Report with Literature Review

Clear cell hidradenoma is an uncommon benign skin appendageal tumor that typically involves the dermal layer of the head, face, and extremities. The breast is a rare site for this lesion, with only two documented cases, which were determined based on mammogram and sonogram findings. We present a case of clear cell hidradenoma of the axillary tail with radiological findings and a literature review.

Syringocystadenoma papilliferum as a cutaneous mass in an unusual location. A case report

Syringocystadenoma papilliferum [SP] is an uncommon adnexal adenoma, most often located on head and neck. We described an unusual appendage tumour, most importantly appearing at later age with vulvar location adjacent to the labio-femoral sulcus situated in the cutaneous tissue and having rapid growing pattern. Different prominent Ig class was found in the secretory component of the tumour epithelial cells and in the plasma cells underlying the tumour epithelium. A diagnosis of SP was made by characterizing histopathologic features of the biopsy specimen

Espiradenoma ecrino: revisión de cuatro casos / Ecrine spirodenoma: review of 4 cases

Se describen cuatro casas de pacientes portadores de espiradenoma ecrino, tratados en el Hospital José Joaquín Aguirre. Se analizan los aspectos clínicos e histopatológicos de cada uno de ellos. El espiradenoma ecrino es un tumor anexial benigno, poco frecuente. Generalmente se presenta como un nódulo doloroso, único, localizado en la cabeza o tronco. La histopatología se caracteriza por mostrar un tumor bien delimitado, constituido por una masa epitelial compuesta de lóbulos basofílicos en dermis e hipodermis. El tratamiento consiste en su extirpación quirúrgica

Clear cell hidradenoma of the eyelid: a case report.

Sweat gland tumours are extremely rare in the eyelids. We report a case of a clear cell hidradenoma (nodular hidradenoma) in an elderly female, who had presented with a nodular swelling in a eyelid. Clear cell hidradenomas arise as intradermal nodules from eccrine sweat glands. Ultrastructural and enzyme histochemical studies have shown nodular hidradenomas to be intermediate between eccrine poroma and eccrine spiradenoma. No apocrine differentiation has ever been observed in these tumours. Malignant forms are distinctly unusual. This case is being documented for the extremely uncommon presentation of this tumour as an eyelid mass. Complete primary excision is advocated and local steroid preparations should bot be used.

Hidroadenoma a células claras / Clear cell hydradenoma

El hidroadenoma a células claras es un tumor benigno de las glándulas sudoríparas ecrinas, denominado de varias maneras; algunos de sus sinónimos son el de "acroespiroma ecrino" e "hidroadenoma nodular", entre otros. Presentamos el caso de un paciente con una lesión tumoral dolorosa en la región frontal, cuyo diagnóstico definitivo fue de hidroadenoma a células claras, lo cual motivó a realizar una revisión del tema
