RESUMO
Thymic stromal lymphopoietin (TSLP) is known to be associated with allergic diseases. It is also suggested that TSLP has a role in autoimmune diseases such as psoriasis; however, the associated pathways remain unknown. There is currently little information on TSLP in psoriasis vulgaris. We investigated TSLP expressions on lesional and non-lesional skin of psoriasis vulgaris patients using reverse transcription- polymerase chain reaction. TSLP level was also investigated in serum from psoriasis vulgaris patients compared to healthy control using enzyme-linked immunosorbent assay. TSLP expression was higher in lesional skin (1.90) compared to non-lesional skin (1.76); however, the difference was not statistically significant (P>0.05). TSLP serum levels were significantly higher in psoriasis patients (287.40 pg/dL) as compared to controls (114.70 pg/dL) (P<0.05). This study concluded that TSLP levels in the serum of psoriasis vulgaris patients are higher than controls. TSLP was also found in keratinocyte of psoriasis patients, the expression was higher in the lesional compared to non-lesional skin; however, this difference is statistically insignificant. These findings suggest that TSLP may play a role in the pathogenesis of psoriasis vulgaris, but its exact role remains unclear.
RESUMO
Cutaneous tuberculosis (TB) has several clinical manifestations. The most common forms include cervical scrofuloderma and plaque type of lupus vulgaris (LV), otherwise the rare cases including inguinal scrofuloderma, ulcerative LV, and acute miliary TB. The highlight of this case series was to report various rare clinical manifestations of cutaneous TB.
