Extensive cutaneous iatrogenic Kaposi's sarcoma after bullous pemphigoid treatment with oral methylprednisolone: a rare Chinese case report.

Bullous pemphigoid (BP) is an autoimmune disease that requires immunosuppressive therapy. Systemic corticosteroids are considered the standard treatment for moderate-to-severe BP. Kaposi's sarcoma (KS) is a rare multifocal endothelial tumour that affects the skin, mucosa and viscera.

Clinical profile of cutaneous adverse drug reactions: a retrospective study of 1883 hospitalized patients from 2007 to 2016 in Shanghai, China.

Background: Cutaneous adverse drug reactions (CADRs) are drug-induced skin reactions with or without systemic involvement, ranging from mild maculopapular exanthema (MPE) to life-threatening severe CADRs (S-CADRs). Due to their unpredictability and severity, early recognition of suspected causative drugs is highly recommended. However, the profile of CADRs remains unknown in China.

HLA-A*02:01 allele is associated with tanshinone-induced cutaneous drug reactions in Chinese population.

Tanshinone, a widely used Chinese patent medicine, has been confirmed to have various kinds of pharmacological effects although frequently causing cutaneous adverse drug reactions (cADRs). We aim to identify whether human leukocyte antigen (HLA) class I alleles are associated with tanshinone-induced cADRs in Han Chinese. The association study including 18 patients with tanshinone-induced cADRs, 67 tanshinone-tolerant volunteers, and two general population databases consisted of 10,689 and 169,995 healthy subjects was performed.
