NORONHA, Lúcia de; GARCIA, Mariana Jorge and BEPPLER, Maria Betânia. Melanocytic nevus associated with syringofibroadenomatous hyperplasia: a case report. An. Bras. Dermatol. [online]. 2006, vol.81, suppl.3, pp. S301-S308. ISSN 1806-4841. http://dx.doi.org/10.1590/S0365-05962006000900011.
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.
