Real-life effectiveness and safety of baricitinib in patients with severe alopecia areata: A 24-week Italian study.

BACKGROUND: Alopecia areata is an autoimmune condition characterized by rapid hair loss in the scalp, eyebrows and eyelashes, for which treatments are limited. Baricitinib, an oral inhibitor of Janus kinases 1 and 2, has been recently approved to treat alopecia areata. MATERIALS AND METHODS: We conducted a retrospective study involving 23 medical centres across Italy, enrolling patients affected by severe alopecia areata (SALT >50), for more than 6 months. Clinical and trichoscopic assessment was performed at each visit and impact on quality of life, anxiety and depression were evaluated using the Skindex-16 and the Hospital Anxiety and Depression Scale (HADS), respectively. RESULTS: A total of 118 patients were enrolled, with a mean age of 39 years and a mean SALT >95. The mean value of the SALT score decreased from an average of 96.6 (±8.23 sd) to 48 (±35.2 sd) after 24 weeks of treatment and 42.3% of patients achieved a SALT 30, 31.3% a SALT 20 and 20.3% a SALT 10 by Week 24. Trichoscopic signs showed fewer yellow dots and black dots significantly earlier than hair regrowth. Adverse events during the treatment period (mild laboratory test abnormalities) were reported in 12.7% patients. No drop-out were registered. CONCLUSION: Data on the effectiveness and safety of baricitinib are promising and support the use of this drug in severe forms of AA, also in the early stages. We also suggest performing trichoscopy in order to reveal early response to therapy.

Progressive late-onset of cutaneous angiomatosis as possible sign of cerebral cavernous malformations.

BACKGROUND: Cerebral cavernous malformations (CCM) comprise enlarged capillary cavities in the central nervous system, with possible retinal or cutaneous vascular malformations. This condition is associated with CCM1, CCM2, and CCM3 gene mutations. OBJECTIVE: Cutaneous clinical, histological and cerebral MRI findings, including CCM1, CCM2, and CCM3 gene sequencing, of two unrelated, neurological symptom-free patients who consulted for late-onset of deep multiple cutaneous angiomatoid lesions, are described. RESULTS: The diagnosis of multiple cutaneous angiomatosis was confirmed and related to CCM as detected by MRI in both cases. Analysis of our patients showed normal nucleotide sequences of the genes proposed. CONCLUSIONS: A progressive late-onset of multiple, deep cutaneous venous malformations may indicate the need to investigate a potential coexistence of CCM by MRI. Early diagnosis and prompt treatment is required in these patients. The absence of CCM1, CCM2, and CCM3 mutations might indicate that different genes could be involved in the pathogenesis of these late-onset patients. Careful questioning about family history of CCM is important; our first patient's daughter had a history of cerebral cavernoma.

Dermoscopic Analysis of 72 "Atypical" Seborrheic Keratoses. / Análisis dermatoscópico de 72 queratosis seborreicas «atípicas¼.

BACKGROUND: Seborrheic keratoses (SK) are easily recognizable by clinical and dermoscopic approach, nevertheless, some lesions act as a simulator of different skin conditions lacking typical clinical and dermoscopic criteria. OBJECTIVE: The aim of our study was to find specific dermoscopic features or a global pattern to improve diagnostic skills for challenging SK. MATERIALS AND METHODS: We examined 72 atypical SK excised from September 2014 up to September 2017 by using the 2-step algorithm modified by Malvehy (2002) and Argenziano (2003). RESULTS: In our study population, an average of 4.04 out of 15 dermoscopic specific criteria for SK was found (for example, multiple milia-like cysts). Additional criteria not included in 2-step algorithm were blue-whitish veil (found in 3 SK; 4.2%), polymorphous vessels (18 SK; 25%), blotch/globules (6 SK; 8.3%), shiny white streaks (3 lesions; 4.2%). The most represented global patterns were reticular (27 SK; 37.5%) and not specific (15 SK; 20.8%). All lesions exhibited peculiar findings of SK, furthermore elements suggestive for melanocytic lesion were found in 79.2% of all lesions. Comparing the literature and our results, we found 3 significant differences: a) the less prevalence of SK specific criteria in our study population; b) the description of findings usually not related to SK, among which blue-whitish veil, polymorphous vessels, blotch/globules and shiny white streaks, and c) 2 patterns not previously defined represented by "not specific pattern" (20.9% of all lesions examined) and "vascular pattern" (12.5% of all lesions examined) were also described. No specific feature or global pattern, statistically significant for dermoscopic diagnosis of difficult-to-diagnose SK have been found. CONCLUSION: Nevertheless the useful findings, no specific feature or global pattern statistically significant for dermoscopic diagnosis of challenging SK have been found. According to the 2-step algorithm and the dermatoscopic scoring system for melanocytic and not melanocytic lesion, SK with one or more dermatoscopic findings typical of melanocytic lesion should be removed surgically to exclude classic melanoma or melanoma mimicking SK.
