It showed cytoplasmic pattern in 23 cases (65.7%) and nuclo-cytoplasmic pattern in 12 cases (34.3%). Epidermal localization occupied the whole thickness in 15 cases (42.85%) and the basal cell layer in 20 cases(57.1%). Epidermal H score had a mean ± SD value of 85.4±47.9. Epidermal H score category is low in 31 cases (88.6%) and high in 4 cases (11.4%) (Table …show more content…
The dermal adnexal LXR-α expression was positive in all of them. All of them showed cytoplasmic pattern and all occupied the whole thickness. dermal H score had a mean ± SD value of 67±33. Dermal H score category is low in all cases (Table 2).
(3) Lesional skin
(a) Epidermis: Epidermal expression was positive in all cases. Epidermal pattern was cytoplasmic in 8 cases (22.9%) and nucleocytoplasmic in 27 cases (77.1%). Epidermal localization occupied the whole epidermal thickness in 14 cases (40%) and the basal cell layer in 21 cases (60%). Epidermal H score had a mean ± SD value of 113.4±50.8. Epidermal H score category is low in 25 cases (71.4%) and high in 10 cases (28.6%) (Table 2).
(b) Dermis: 14 of the examined samples contained dermal adnexa. The dermal adnexal LXR-α expression was positive in all of them. All of them showed cytoplasmic pattern. Dermal localization occupied the whole thickness in 10 cases and the outer root sheath in 4 cases Dermal H score had a mean ± SD value of 79.29±41.04. Dermal H score category is low in all cases (Table 2).
