Unexpected Extensive Hair Whitening Following Baricitinib Treatment for Alopecia Universalis: A Case Report and Mechanistic Insights.

Alopecia universalis (AU) is a severe form of alopecia areata characterized by the complete loss of scalp and body hair. While Janus kinase (JAK) inhibitors like baricitinib have shown promise in promoting hair regrowth in severe cases of AU, unexpected side effects, such as hair depigmentation, have not been widely reported. We present the case of a young male with AU who experienced progressive and extensive whitening of his scalp and body hair following treatment with baricitinib.

Cold atmospheric plasma applications in dermatology: A systematic review.

Cold atmospheric plasma (CAP) applications can potentially lead to effective therapy for numerous skin diseases. Our aim is to systematically review the available data and map the use of CAP in dermatology. PubMed, Embase and Web of science were explored before 2020 for studies regarding the use of CAP in dermatology.

A case of nodal marginal zone lymphoma with hypersensitivity to mosquito bites as initial symptom.

Hypersensitivity to mosquito bites (HMB) refers to skin reactions such as bullae and necrosis, which occurs after being bitten by mosquitoes and can present with multiple systemic reactions such as fever, lymphadenopathy, hepatosplenomegaly simultaneously or subsequently. A 48-year-old male patient presented with recurrent erythema, nodules, papules, vesicles and bullae over upper body and bilateral limbs with itching over the sites of mosquito bite for more than 1 year with low-grade fever and superficial lymph nodes enlargement. The patient's symptoms failed to improve from conventional anti allergic treatment although skin biopsy showed changes of HMB reaction.
