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.

Abstract Frontal fibrosing alopecia is a distinctive form of scarring alopecia considered to be a clinical variant of lichen planopilaris. It predominantly occurs in postmenopausal women and has a slowly progressive course. It was first described by Kossard in 1994. Since then the number of reported cases has increased significantly. Coexistence of frontal fibrosing alopecia and autoimmune disorders - such as discoid erythematosus lupus and Sjögren's syndrome - may suggest a common pathogenic background among the diseases.

Abstract: We describe the case of a 9-year-old boy with idiopathic bone marrow aplasia and severe neutropenia, who developed skin ulcers under cardiac monitoring electrodes. The diagnosis of primary cutaneous aspergillosis was made after the second biopsy and culture. Imaging investigation did not reveal internal fungal infection. The child was treated, but did not improve and died 3 months after admission. The report highlights and discusses the preventable risk of aspergillus skin infection in immunocompromised patients.
