Multiple eccrine hidrocystomas of de upper lip are bening cystic lesions that are associated with a chronic course. It is reported in the literature as a rare pathology.
We describe the case of a 60-year-old woman who was referred to the dermatology department for presenting multiple lesions translucent papular asymptomic two years of evolution on the upper lip. Increase in size in summer and physical exercise, improving winter.
To make the diagnosis of multiple eccrine hidrocystomas is necessary clinical and histopathological findings, taking different lines of treatment.
Eccrine hidrocystomas are cystic tumor the sweat glands ducts, are relatively rare and account less than 1% of sumitted cutaneous biopsies . They are more frequent in fermales between 30 and 70 years of age and can occur as solitary or multiple cyst. Multiple eccrine hidrocystoma occur more frecuently around the eyes, cheeks, nose and less frecuently on the upper lip .
The eccrine hidrocystoma has been considered to be true ectatic eccrine ducts of the dermal portion. The occurrence of these injuries was caused by retention of sweat favored by increased temperature and physical exercise . There is an increased incidence in hyperthyroid patients, possibly related to hyperhidrosis. When the presentation is simply a cyst it may be mistaken with epidermal inclusión cyst, mucoid cyst and hidrocystoma apocrine. From the clinical point of view el eccrine hidrocystoma and apocrine hidrocystoma are difficult to distinguish; to be diagnosed histopathology is necessary. Apocrine hidrocystoma usually presented as multiple cysts and may have abundant papillary proyections into the cyst cavity or only have a simple apocrine type lining cell with large cytoplasm, PAS-positive diastase resistant granules, showing the beheading events of decapitation surrounded by myoepithelial cells . However the eccrine hidrocystomas are usually unilocular showing two layers of epitelial cuboidal without decapitation events or presence of myoepithelial cells. Have been described associated with Graves Basedow disease, Goltz-Gorlin and Schopf-Schulz-Passarge syndromes.
In regard of treatment, when are unique lesions performed surgical excision when are multiple lesions several treatments have been described with favorable response; tópica 1% atropine or scopolamine creams, with a 585 mm flashlamp-pupel pulse dye laser and botulim toxim [5, 6].
Eccrine hidrocystoma is not a serius injury but it is a mainly problem cosmetic.
