Does HSP90 play an important role in psoriasis?

Introduction: Psoriasis is a chronic, inflammatory skin disease. Environmental, genetic, autoinflammatory and autoimmune factors play a role in the pathogenesis of disease. It is believed that heat shock protein 90 (HSP90) is an interleukin-17 (IL-17) receptor, which plays an essential role in the psoriasis pathogenesis.

X-linked TLR7 gene polymorphisms are associated with diverse immunological conditions but not with discoid lupus erythematosus in Polish patients.

Introduction: Toll-like receptor 7 (TLR7) is an important molecule involved in the development of autoimmunity and the response to different pathogens. Several polymorphisms within the gene were previously found to be associated with systemic lupus erythematosus (SLE). However, none of those studies investigated the promoter flanking variants rs1634318 and rs1616583.

Genetic similarities and differences between discoid and systemic lupus erythematosus patients within the Polish population.

Introduction: Many studies have shown that some SNPs might be a risk factor for systemic lupus erythematosus (SLE), but little is known about potential susceptibility loci of the skin types of the disease. Discoid lupus erythematosus (DLE) is the most common form of the cutaneous lupus erythematosus. Nevertheless, a genetic contribution to DLE is not fully recognized.

Human papillomavirus-related verrucous carcinoma in a renal transplant patient after long-term immunosuppression: a case report.

Background: Verrucous carcinoma is a slow-growing tumor with 3 main localizations: Oral cavity, ano-urogenital region, and plantar surface of the foot. On the sole it may rise adjacent to viral warts and very often is mistaken for the common verruca plantaris. Although both conditions-viral warts and cutaneous squamous cell carcinoma-are often diagnosed in immunosuppressed patients, in literature we have found only 3 case reports of verrucous carcinoma in organ transplant recipients.

Sweet's syndrome with idiopathic thrombocythemia.

Diagnosis of paraneoplastic skin syndromes associating neoplastic processes is assumed as the crucial aspect of dermatological practice. Knowledge of clinical findings of dermatoses suggesting coincidence of malignant proliferative processes facilitates diagnostic and therapeutic procedures. We would like to present a case of Sweet's syndrome, qualified for comparative paraneoplastic skin syndromes.
