Hidroacanthoma simplex: dermoscopy and cryosurgery treatment

Abstract

Hidroacanthoma simplex is a rare intraepidermal neoplasia that arises from the acrosyringial portion of the eccrine duct. Malignant transformation of hidroacanthoma simplex is reported in the literature and the treatment is performed with wide excision or Mohs micrographic surgery. We report the first case successfully treated with cryosurgery with a long-term follow up.

A dermoscopic pitfall in a long‐standing tumor

“…Die vaskulären Muster waren unspezifi sch. Es konnten irreguläre lineare, glomeruläre und haarnadelartige Gefäße vorliegen [ 6,7 ] . Auch Melanom-ähnliche dermatoskopische Strukturelemente wie strahlenförmige Ausläufer, Regressionszeichen, blauweißer Schleier und Blotches (Tintenfl ecke) wurden bei Hidroacanthoma simplex beschrieben [ 7 ] .…”

“…Maligne Transformationen eines langjährig bestehenden Hidroacanthoma simplex wurden, wenn auch selten, unter verschiedenen Namen wie ekkrines Porokarzinom oder Porokarzinom in situ beschrieben. Eine zuverlässige Diagnose ist daher unerlässlich, um die Entstehung einer malignen Variante aufgrund einer ungeeigneten Therapie zu vermeiden [ 6,8 ] .…”

Roles of Epiluminescence Dermoscopy beyond the Diagnoses of Cutaneous Malignancies and Other Skin Diseases

“…If the dermoscope goes wrong in a dermatoscope-guided operation, the clinician might merely switch his eyesight from the monitor to the patient and proceed with the operation smoothly. Dermoscopy is commencing to be applied to a wide range of surgical procedures for skin diseases [28][29][30].…”

Clinical, dermoscopic, and histopathologic findings of hidroacanthoma simplex: Literature review and case report

“…Hidroacanthoma simplex (HS) is a rare intraepidermal benign tumor in the acrosyringeal portion of the eccrine duct [1][2][3][4][5][6][7][8][9] . HS is frequently found on the lower limbs and trunk, and the lesions present as a flat brownish or verrucous plaque [1][2][3][4] .…”
