RESUMO
Syringomatous tumor of the nipple is a benign, locally infiltrative tumor. There are reports in the literature of tumor recurrence in cases of incomplete excision. Clinical and mammographic findings in syringomatous tumors are like those of breast carcinoma and the pathologist has a fundamental role in final tumor diagnosis. Therefore, the aim of this study was to report a case of syringoma located in the areolar region. A 33-year-old woman reported that she had noticed a nodule in her left areolar region 4 years previously (February 2019). A breast ultrasound was performed, detecting intraparenchymatous breast cysts. Surgical resection of the nodule was indicated although it was not performed. Two years later, in August 2021, the patient underwent a mastopexy with prosthesis inclusion. Histopathology study of the surgical specimen revealed a syringomatous tumor with positive margins. Thirteen (13) months after diagnosis (September 3, 2021 - October 16, 2022), the patient is doing well and receives clinical follow-up.

Syringoma is a benign adnexal tumor of the skin originating from the eccrine sweat duct. There is a wide variety of treatments, and most of the patients receive multiple unsuccessful therapies. The goal of this report intends to describe a novel technique applicable to syringoma with botulinum toxin A. A 61-year-old female patient with localized syringomas in the periocular and upper lip region, with a long-lasting history, treated with botulinum toxin A 46 IU as monotherapy intradermally distributed and a follow-up for 8 months. Our patient displayed a significant improvement of the syringomas. Botulinum toxin A is an efficient and safe technique to treat syringomas.

INTRODUCCIÓN: Los siringomas son tumores benignos derivados de la porción intraepidérmica de los conductos sudoríparos ecrinos. Ocasionalmente pueden iniciar de forma súbita como siringomas eruptivos o localizarse en sitios atípicos que retrasan el diagnóstico por años. La dermatoscopía tiene un rol incipiente en diferenciar siringomas de su extenso diagnóstico diferencial. MÉTODOS: Estudio retrospectivo descriptivo de serie de casos de siringomas de localización atípica. Los datos fueron extraídos de fichas clínicas electrónicas. Todos incluyen dermatoscopía y correlación histopatológica. RESULTADOS: Cinco pacientes. Cuatro hombres y una mujer entre 40 y 79 años de edad con siringomas atípicos: cuatro casos eruptivos y un caso de siringomas vulvares. DISCUSIÓN: Proponemos la dermatoscopía basada en nuestros hallazgos como una herramienta útil con estructuras ovales amarillas y una pseudo-red café clara difusa en su superficie. Estas estructuras amarillas se pueden correlacionar con la proliferación ductal ecrina y el denso estroma en la histopatología. CONCLUSIÓN: Enfatizamos que se debe considerar esta entidad en el diagnóstico diferencial de dermatosis papulares y conocer sus manifestaciones clínicas para optimizar la sospecha diagnóstica.
INTRODUCCTION: Syringomas are common benign tumors, probably of origin derived from the intraepidermal portion of the eccrine sweat ducts. Occasionally they may develop suddenly and extensively as eruptive syringomas or be located in atypical sites delaying the diagnosis for years. Dermoscopy has an incipient role in differentiating syringomas from their extensive differential diagnosis. METHODS: Retrospective descriptive case-series study of atypical location syringomas. Data extraction from clinical history from electronic files. They all include dermoscopy and histopathological correlation. RESULTS: Five patients: Four men and one woman between 40 and 79 years old, with atypical syringomas diagnosis: four eruptive and one vulvar syringomas. DISCUSSION: We propose dermoscopy, based on our findings, as a useful tool to this entity, with its oval yellow structures and a diffuse light-brown network-like structure on its surface. These yellow enlargements may be correlated with the ductal eccrine proliferation and the dense stroma seen in the histopathology. CONCLUSION: We emphasize that they should be considered in the differential diagnosis of papular dermatosis, as they tend to be underdiagnosed, and to know their clinical manifestations to optimize the diagnostic suspicion.

BACKGROUND Syringoid eccrine carcinoma (SEC) is an extremely rare malignant adnexal neoplasm derived from eccrine sweat glands, of unknown pathogenesis. We report a case of this rare entity presenting in the abdomen, which is the only one reported in this area and the only case of SEC in a patient with so many comorbidities. CASE REPORT A 58-year-old black male from Brazil reported a nodular lesion in the abdomen with a progressive increase in size and pain and local burning sensation. The histopathological examination showed a syringoid eccrine carcinoma. CONCLUSIONS We present a rare case of SEC and did an extensive literature review in order to describe the clinical characteristics, histopathological findings, immunohistochemical profile, treatments, and difficulties found in the diagnosis of this tumor. To avoid misdiagnosis, we gave special attention to biopsy quality.

El siringocistoadenoma papilífero (SCAP) es un tumor anexial benigno, poco frecuente, que deriva de las glándulas sudoríparas écrinas o apócrinas. Afecta a ambos sexos por igual, se observa desde el nacimiento o en la primera infancia. Se manifiesta como una placa solitaria alopécica en cuero cabelludo, o como pápulas de color piel en rostro y cuello. En el 40% de los casos se asocia a un nevo sebáceo preexistente. El tratamiento de elección es la extirpación quirúrgica. Se presenta un varón de 14 años, con un nevo de Jadassohn presente desde el nacimiento, que desarrolló años posteriores un SCAP. Palabras clave Nevo de Jadassohn, nevo sebáceo, siringocistoadenoma papilífero, tumor anexial benigno.
The syringocystadenoma papilliferum (SCAP) is an adnexal benign tumor, uncommon, which derives from the eccrine or apocrine sebaceous glands. It affects both sexes equally, it occurs most frequently from birth or early childhood. It manifests clinically as a solitary raised plate located mainly on scalp, or as papules in face, and neck. In 40% of the cases it is associated with a pre-existing sebaceous nevus. The treatment of choice is surgery. We present a 14 year old male, with a history of a nevus of Jadassohn present from birth, that years later developed a SCAP

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.

Collision or contiguous tumors, defined as two or more distinct tumors occurring at one site, are often an unexpected finding and may represent a diagnostic challenge, as clinical and histological presentations do not always coincide. Various combinations of collision tumors have been described with respect to melanocytic lesions, with the most frequently reported being the combination of nevus and basal cell carcinoma. We present an unusual case on the nose involving a melanoma in situ and a clinically-inapparent syringoma, which, to the best of our knowledge, is the first report of this combination.

Syringocystadenoma papilliferum and tubular apocrine adenoma are rare benign sweat gland tumors. Syringocystadenoma papilliferum occurs alone or in association with other tumors. Although it is rare, the association of tubular apocrine adenoma with syringocystadenoma papilliferum developing in a sebaceous nevus on the scalp is well documented. However, the co-existence of these two tumors without the background of a sebaceous nevus has not been frequently reported. Syringocystadenoma papilliferum and tubular apocrine adenoma may have a histopathological overlap, but a few cases of a syringocystadenoma papilliferum combined with a tubular apocrine adenoma have been reported. Herein we describe an unusual case of syringocystadenoma papilliferum co-existing with a tubular apocrine adenoma located on the back of a 14-year-old patient in the absence of a pre-existing sebaceous nevus.

Although it is rare, the association of tubular apocrine adenoma with syringocystadenoma papilliferum developing in a sebaceous nevus on the scalp is well documented. However, the co-existence of these two tumors without the background of a sebaceous nevus has not been frequently reported. Syringocystadenoma papilliferum and tubular apocrine adenoma may have a histopathological overlap, but a few cases of a syringocystadenoma papilliferum combined with a tubular apocrine adenoma have been reported. Herein we describe an unusual case of syringocystadenoma papilliferum co-existing with a tubular apocrine adenoma located on the back of a 14-year-old patient in the absence of a pre-existing sebaceous nevus.
