A Case of Acrodermatitis Continua of Hallopeau Following Chronic Pustular Cheilitis.

We describe the case of a young male affected by chronic pustular psoriasis of the lips that remained the only manifestation of acrodermatitis continua of Hallopeau (ACH) for years before the onset of the characteristic hand lesions.

Dermatofibrosarcoma protuberans in an adolescent: a case report and review of the literature.

Classically, dermatofibrosarcoma protuberans (DFSP) is a disease of adults. The world literature revision shows that several pediatric cases have been reported so far; this might suggest that the number of infants with the condition might be larger than that estimated previously. Here, we report the 183rd case of histologically confirmed DFSP in young age.

Dermoscopic, histological and immunohistochemical evaluation of cancerous features in acquired melanocytic nevi that have been repeatedly exposed to UVA or UVB.

Previous studies have reported that repeated solar and artificial UVB (280-320 nm) and UVA (320-400 nm) exposures can modify acquired melanocytic nevi (AMN). We therefore investigated the clinical, dermoscopic, histological and immunohistochemical changes in AMN exposed to UVB and UVA radiation. Twenty healthy volunteers with at least three AMN on the trunk were enrolled in the present study and randomized into two groups to receive equally effective doses of narrow-band (NB)-UVB or UVA1.

Interval sentinel lymph nodes: an unusual localization in patients with cutaneous melanoma.

Background. Recent studies have demonstrated that there exists a great variation in the lymphatic drainage in patients with malignant melanoma. Some patients have drainage to lymph nodes outside of conventional nodal basins.
