Introduction: Eccrine angiomatous hamartoma is characterized by a proliferation of multiple eccrine and vascular structures, generally presenting from birth, with growth proportional to the individual, as solitary or multiple plaques or nodules of variable color that mainly affect the distal extremities. The exact pathogenesis is unknown, but several theories have been proposed, including abnormal heterotypic dependency induction with resulting malformation of adnexal and mesenchymal elements. The diagnosis must be confirmed with a histopathological study, where a neoplasm in the middle or deep dermis with proliferation of eccrine glands and vascular structures will be found. For symptomatic patients, surgical excision is the treatment. [ABSTRACT FROM AUTHOR]

É apresentado um caso de carcinoma ductal écrino cutâneo primário na região parietal do couro cabeludo em paciente de 77 anos. A biópsia mostrou carcinoma de padrão ductal, infiltrante, sugestivo de neoplasia metastática. Foi identificada infiltração por adenocarcinoma de padrão tubular écrino. O paciente foi encaminhado ao Mastologista e Oncologista, que não detectaram lesões primárias em outros órgãos. Diante da clínica e análise imuno-histoquímica, o diagnóstico foi de carcinoma écrino primário da pele. Para tratamento, realizou-se cirurgia micrográfica de Mohs, em três fases para obter margem livre. O tumor apresentava infiltração profunda da tela subcutânea e gálea aponeurótica.

Hyperhidrosis represents a benign disease; whose cause is unknown; it is secondary to the dysfunction of the eccrine glands due to cholinergic overstimulation and its diagnosis is usually clinical. There are two types of hyperhidrosis: idiopathic or secondary to neoplasms, infections and medications, among others. It is an illness with significant impact on the quality of life of the patient. There are several treatments available, medical and surgical; the first one is mainly effective in the management of mild to moderate hyperhidrosis. [ABSTRACT FROM AUTHOR]

O porocarcinoma écrino é uma neoplasia maligna, rara, das glândulas sudoríparas écrinas e, com maior frequência, acomete os indivíduos idosos, com idade média de 67,5 anos. Apresenta manifestações clínicas variadas e sua localização não se correlaciona com a concentração das glândulas sudoríparas, ocorrendo, principalmente, nos pés e pernas. O seu diagnóstico e tratamento devem ser precoces para evitar a agressividade do tumor, que ocorre em 20% dos casos. Os autores relatam o caso de um porocarcinoma extenso no tórax, em paciente do sexo masculino, de 71 anos.Eccrine porocarcinoma is a rare, malignant neoplasm of eccrine sweat glands. It often occurs in elderly people, mean age of 67.5 years. The clinical features are variable and their localization is not related to sweat-gland concentration, occurring mainly on the feet and legs. Disease diagnosis and treatment should be as early as possible in order to avoid tumor aggressiveness that occurs in 20% of the cases. The authors present a case of extensive porocarcinoma on the thorax of a 71-year-old male patient.

FUNDAMENTO: Siringoma é tumor anexial benigno do ducto sudoríparo écrino cujo tratamento é realizado por diversas modalidades cirúrgicas com resultados variáveis. OBJETIVO: 1. Relatar a experiência no tratamento cirúrgico de siringomas periorbitários mediante excisão com a tesoura oftalmológica de Castroviejo, seguida pela cicatrização por segunda intenção. 2. Apresentar revisão da literatura com enfoque no aspecto terapêutico. MATERIAL E MÉTODOS: Em 68 meses foram tratados 38 pacientes com siringomas periorbitários. Realizada a exérese cirúrgica com tesoura oftalmológica de Castroviejo seguida pela cicatrização por segunda intenção. Realizadas avaliações sete, 30 e 90 dias após a cirurgia. O seguimento variou entre três e 62 meses, com média de 33 meses. RESULTADOS: Dos 38 pacientes tratados, 63,1% tiveram resultado ótimo, 31,6% bom e 5,3% regular. A única complicação imediata observada foi edema, e as tardias foram: hipocromia (12 casos), cicatriz deprimida (um caso) e hipertrófica (um caso). Não ocorreram recidivas no período observado. CONCLUSÕES: O tratamento dos siringomas periorbitários mediante exérese cirúrgica com tesoura oftalmológica de Castroviejo, seguida pela cicatrização por segunda intenção, constitui procedimento ambulatorial de baixo custo e fácil execução. Proporciona resultados satisfatórios, sem recidivas, apesar da possibilidade de ocorrer hipocromia transitória.BACKGROUND: Syringomas are benign adnexal tumors from intraepidermal eccrine ducts, treated by diverse surgical modalities with variable results. OBJECTIVES: 1. To report our experience in surgical treatment of multiple periorbital syringomas excised by Castroviejo scissors followed by healing by secondary intention. 2. To present a literature review with emphasis on therapeutic aspects. MATERIAL AND METHOD: During 68 months we treated 38 cases of periorbital syringoma. All of them were submitted to surgical excision using Castroviejo scissors, followed by healing by secondary intention. Evaluation was done 7, 30 and 90 days after surgery. The mean follow-up period was 33 months, ranging from 3 to 62 months. RESULTS: The results were excellent in 24 patients (63.1%), good in 12 patients (31.6%) and regular in two patients (5.3%). The only immediate complication observed was edema; late complications were hypochromia (12 patients), depressed scar (one patient) and hypertrophic scar (one patient). Recurrences were not observed during the follow-up period. CONCLUSIONS: We concluded from our results that excision of periorbital syringomas by Castroviejo scissors followed by healing by secondary intention is a low cost, straightforward outpatient procedure. Results are good, with no recurrences, although transient hypochromia may occur.

O objetivo deste estudo é relatar um caso de lesão verrucosa cujo diagnóstico foi de nevo melanocítico composto associado à hiperplasia siringofibroadenomatóide. O paciente foi submetido a exérese de lesão cutânea abdominal com diagnóstico clínico de nevo melanocítico de Miesher. A microscopia óptica revelou epiderme hiperplásica e derme com ninhos de células névicas intimamente associados com aglomerados de ductos écrinos e arranjados segundo um padrão siringomatóide. A concomitância de hiperplasia epidérmica e proliferação siringomatóide é definida como siringofibroadenomatose écrina e pode ser devida a fatores de crescimento secretadas pelo estroma alterado.The aim of this study was to report a case of a verrucous lesion diagnosed as a compound melanocytic nevus associated with syringofibroadenomatous hyperplasia. The patient was submitted to excision of the abdominal skin lesion and diagnosed as Miesher melanocytic nevus. Optical microscopy revealed epidermal hyperplasia and dermis with nests of nevus cells intimately associated with eccrine duct clusters arranged in a syringoid pattern. The coexistence of epidermal hyperplasia and syringomatoid proliferation is defined as eccrine syringofibroadenomatosis and may result from growth factors released by the impaired stroma.

A case of an eccrine poroma is described in a 77 year-old patient with a painful lesion on his right foot, with easy bleeding and limitation for deambulation. Histology reported eccrine poroma. A review of current literature is made. [ABSTRACT FROM AUTHOR]
