Syringoma: a review of twenty-nine cases.
The purpose of our study was to identify the clinical characteristics, epidemiologic data and histologic features in 29 cases of syringoma with a duration of lesions prior to the observation between 1 and 25 years. Only one patient complained of moderate itching. In two cases the lesion was solitary, in another the papules formed a lichenified plaque. In six patients only the eyelids were involved and in two patients a symmetrical localization on the forearms was observed. The other 18 patients showed generalized syringoma, 16 with an eruptive onset, 6 of which were familial. One of our cases showed lesions mimicking urticaria pigmentosa and two patients were affected by Down's syndrome. In two cases, histopathology showed association between syringoma and a melanocytic naevus and in one patient with a solitary lesion a clear cell syringoma was observed.
