“…A significantly lower incidence of skin involvement was revealed in our results for adolescent patients compared to paediatric patients. Previous studies point out that cutaneous LCH is “a great imitator” that has diverse presentations and might contribute to high rates of misdiagnosis[ 37 , 38 ]. The proportion of LCH skin involvement decreases with age[ 11 , 39 ], with an incidence of 38–68% in children with LCH[ 37 , 40 , 41 ] and 5–37% in older children or adults with LCH[ 28 , 29 , 39 ].…”

“…Su presentación clínica es variable e incluye lesiones similares al impétigo en los pliegues axilares e inguinales, pápulas exudativas en la región perianal, lesiones en el cuero cabelludo que se asemejan a la dermatitis seborreica y pápulas amarillentas a eritematoparduzcas con costras hemorrágicas, con o sin ulceración, localizadas en el tronco. La biopsia de piel y la inmunohistoquímica positiva para CD1a y S-100 hacen el diagnóstico (30) . El tratamiento debe realizarse en conjunto con oncología pediátrica y el pronóstico del paciente depende de la extensión y severidad de los órganos involucrados (7,26) .…”

“…Mutasi pada mitogen activated protein kinase (MAPK) pathway ditemukan pada 80% pasien HSL. Gen BRAF (v-Raf murine sarcoma viral oncogene homolog B) merupakan salah satu protein penyusun dari MAPK (RAS-RAF-MEK-ERK) signaling pathway yang normalnya akan mengaktivasi transkripsi faktor untuk pertumbuhan dan proliferasi sel (Claire et al, 2020). Mutasi yang terjadi pada gen BRAF akan mengganggu proses aktivasi dari faktor pertumbuhan sel.…”
