DEAR EDITOR, A 26-year-old woman presented with an asymptomatic linear atrophic lesion on the lower part of the right cheek. The lesion was of nine years' duration and had a very slowly progressive course. The lesion appears as multiple grouped skin-coloured pits taking a linear distribution, measuring about 6 cm in length and following Blaschko's lines. Few open comedones were seen within these pits. A skin biopsy was performed. Histopathological examination revealed cords and strands of basaloid cells arising from the hair follicle infundibulum, extending into the upper dermis and surrounded by scant fibrocellular stroma with no retraction. No cellular atypia or atypical mitoses were noted. S. EL B E H

This study is conducted on back skin of three female belong to Millivora capenesis wild animals. Histological preparations carried out to reveal the structural features of the stratum of epidermis. The skin of Millivora capensis was covered with keratinized stratified squamous epithelium, the mean thickness is 427.85 ± 4.28 μm. The superficial layer is stratum corneum. The basic properties of this stratum consist of dead, flattened, polygonal cells which are free from nuclei and keratin accumulate in dead cells in order to give protective feature. The mean thickness of stratum corneum is 90.5 ± 2.44 μm. Beneath the stratum corneum, there is translucent layar composed of keratin fibrils and homogenous materials which is termed Eldin. The mean thickness of stratum lucidum is 18.14 ± 0.52 μm. While the mean thickness of stratum granulosum intensive affinity to basophilic spinosum is formed from prickle cells with cytoplasmic processes like spines which represented the desmosomes. The mean thickness of both stratum basal is 55.63 ± 1.75 μm .Our histological findings revealed epidermal papillae extended to the papillary layer of dermis, and these papillae were bifurcates and some papillae fused with each other in order to give the rigidity and power to epidermis.
