Photodynamic therapy (PDT) is an effective treatment option for the treatment of superficial basal cell carcinoma (sBCC). Recent publications have demonstrated that PDT with 7.8% 5‐aminolaevulinic acid nanoemulsion‐based gel (BF‐200 ALA‐PDT) is an effective and safe alternative for the treatment of sBCC). To investigate the efficacy and safety of 7.8% 5‐aminolaevulinic acid nanoemulsion‐based gel (BF‐200 ALA)‐PDT for the treatment of sBCC. A non‐controlled, open‐label single centre study was conducted. Patients received one PDT cycle with two PDT sessions one‐week apart. In case that clinical‐dermoscopy evaluation of treatment outcome revealed remaining lesions, a second PDT cycle was performed. The clinical results at the dermoscopy and fluorescence diagnosis level were histologically confirmed in all patients. Treatment response was evaluated 3, 6, and 12 months after last PDT session. A total of 31 patients (12 men and 19 women), with a median age of 63.74 years were included in this study. 3‐month after PDT‐session, 23/31 patients were complete responders (74.19%) after two BF‐200 ALA ‐PDT sessions. Esthetic outcome was considered good‐to‐excellent. 5 Aminolevulinic acid 7.8% nanoemulsion‐based gel (BF‐200 ALA) PDT is an effective therapy option for the treatment of sBCC. Complete clearance rates were higher in those patients who received only one PDT cycle. These results show a similar tendency as shown in other publications. [ABSTRACT FROM AUTHOR]

The external auditory canal (EAC) comprises a special area where erythematous‐scaly diseases are located. Among the main dermatoses that can affect EAC seborrheic dermatitis, psoriasis, irritant or allergic contact dermatitis, chronic external otitis (atrial eczematoid dermatitis) and cutaneous lupus should be considered. In this study, 25 consecutive patients were recruited on our dermatological outpatient clinic, 9 men and 16 women, with a clinical diagnosis of localized erythematous‐squamous dermatoses in EAC. The mean age was 48.8 years (16‐83). The mean time of evolution of the dermatoses was 11.44 months (2‐36). Regarding the diagnosis, 14 patients were diagnosed with seborrheic dermatitis (56%), 9 patients with psoriasis (36%), 1 patient with subacute cutaneous lupus (4%), and 1 patient with allergic contact dermatitis to corticosteroids (4%). The indicated treatment was tacrolimus 0.1% and clotrimazole 1% in otic oil, twice a day, for 1 month. The EAC had to be cleaned initially with saline solution impregnated on a swab from the ears. The IGA score and pruritus showed a high results, with important improvement of almost all patients. The satisfaction of the patients obtained with the TSQM‐9 questionnaire was 95.2. Retreatment showed an equal efficacy observed during the first treatment period. The efficacy and the absence of side effects with the treatment make this magistral formula an adequate therapeutic option for these dermatoses. [ABSTRACT FROM AUTHOR]

Successful treatment of follicular mucinosis with low-dose UVA1 phototherapy A case of follicular mucinosis (FM) after herpes zoster infection (VZV), which can be considered an epithelial reaction pattern defined by follicular mucin accumulation due to different triggers, is presented. Traditionally, UVA1 therapy has been used in the treatment of cutaneous T-cell lymphomas and inflammatory skin diseases. [Extracted from the article]
