Article Synopsis
- Dermoscopy is being evaluated as a non-invasive method to diagnose demodicosis, but previous studies vary in their testing standards and positivity criteria.
- A study reviewed 64 patients, comparing dermoscopic findings with skin scraping results, and found a strong correlation between certain dermoscopic signs (like Demodex tails) and the presence of mites, suggesting dermoscopy could be sufficient for diagnosis.
- The study calculated performance indicators showing that specific dermoscopic signs have high positive likelihood ratios, indicating they could reliably indicate demodicosis.
Article Synopsis
- Researchers studied the effectiveness of methotrexate (MTX) for treating localized scleroderma (morphea) using color Doppler ultrasonography (CDU).
- The study involved 22 patients who underwent multiple CDU examinations and had their disease activity assessed using an Ultrasound Morphea Activity Score (US-MAS).
- Findings indicated that higher MTX doses led to only slight decreases in disease activity, with no cases achieving complete inactivity, highlighting MTX's low effectiveness for morphea treatment.
Monoclonal gammopathies of uncertain significance (MGUS) correspond to pre-malignant hematological disorders characterized by the production of a monoclonal protein and infiltration of less than 10% of the bone marrow by plasma cells. Its importance lies in the risk of progression to malignant disorders and in the association with different renal, neurological and skin manifestations. There are pathophysiological mechanisms that support a causal relationship between monoclonal gammopathies (MGs) and different skin diseases, such as type I cryoglobulinemia (CG), primary systemic amyloidosis (PSA) or necrobiotic xanthogranuloma (NXG).

Molluscum contagiosum (MC) is a self-limited infectious dermatosis, frequent in pediatric population, sexually active adults, and immunocompromised individuals. It is caused by molluscum contagiosum virus (MCV) which is a virus of the Poxviridae family. MCV is transmitted mainly by direct contact with infected skin, which can be sexual, non-sexual, or autoinoculation.

It can be mistaken for basal cell carcinoma. Even though these hamartomas are considered benign lesions, malignant transformation has rarely been reported.
