RESUMO
Eccrine syringofibroadenomatosis (ESFA) is a rare adnexal tumor with acrosyringeal differentiation. Clinically, it can be mistaken for granulomatous infections or malignancies such as squamous cell carcinoma. Despite the rarity of the condition, we recently encountered two cases of the reactive subtype, which occurred in patients with poorly controlled chronic psoriasis. Both patients presented with long-standing, thick verrucous lesions on the lower legs. The diagnosis was made after histological examination and exclusion of infectious and neoplastic disorders. As this is a reactive disorder, management is focused on treating the underlying condition. Unfortunately, psoriasis was difficult to manage in both our patients and they defaulted further treatment. It is important to recognize ESFA as it can be confused with infectious or malignant disorders.
