Abstract
- 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.
