An interpretable CNN-based CAD system for skin lesion diagnosis.

Recently, convolutional neural networks have greatly outperformed previous systems based on handcrafted features once the size of public databases has increased. However, these algorithms learn feature representations that are difficult to interpret and analyse. On the other hand, experts require automatic systems to explain their decisions according to clinical criteria which, in the field of melanoma diagnosis, are related to the analysis of dermoscopic features found in the lesions.

Effectiveness of omalizumab in a case of urticarial vasculitis.

Urticarial vasculitis (UV) is a mainly leucocytoclastic vasculitis with urticarial plaques. Treating these patients is challenging as the available treatments have poor efficacy. Oral corticosteroids are considered the first-line treatment, but H1 antihistamines, dapsone, colchicine, antimalarials, ciclosporin and antileucotrienes have all been tried also.

Lupus Vulgaris Erythematoides: report of a patient initially misdiagnosed as dermatitis.

A small percentage of patients with tuberculosis present with cutaneous findings, which may be difficult to diagnose. We present a patient diagnosed with a rare, non-scarring form of cutaneous tuberculosis (CTB), classically termed as lupus vulgaris erythematoides.
