Angiokeratoma circumscriptum is the rarest variant of angiokeratoma. It usually affects females and it is characterized by dark-red to blue-black confluent papules or nodules on lower limbs in a segmental and unilateral distribution. We describe the clinical and histopathological findings in a patient with angiokeratoma circumscriptum and discuss the etiology, associations, diagnosis, differential diagnosis, and treatment.

All melanocytic neoplasms with histologically-confirmed regression diagnosed in our hospital between 2002 and 2009 were reviewed retrospectively. Lamellar and delicate fibrosis were associated with melanocytic naevi (p <0.

We report 3 cases of patients with a history of melanoma that showed regression of almost all melanocytic nevi over time. One of the patients had 2 simultaneous primary cutaneous melanomas without metastasis.

Thus our objective was to review the records of patients with successive primary melanomas to ascertain whether the pattern of regression might indicate the presence of an immunization effect arising from the first melanoma.
Material And Methods: A review of all the cases recorded in the melanoma database of our dermatology department between 2000 and 2012 identified 19 patients who had multiple asynchronous melanomas (2.
