The diagnosis of human phtiriasis (often referred to as the "crab" or the "pubic louse") can be more difficult than other types of pediculosis (Pediculus corporis and Pediculus capitis) because this insect has a smaller body of 1.2 x 0.8 mm, may be lighter in color, not as mobile and therefore harder to see to the naked eye. Can dermoscopy aid to perform a better analysis of the skin? The clinical experience developed in two patients gives an affirmative answer, moreover adding useful information of insect and its eggs already known to entomologists but never used in dermatological diagnosis. The identification in vivo can distinguish Phthirus pubis from other skin signs while the conical shape of the operculum and the wide fixing sleeve of egg to hair, tells what species of louse is infesting, even if the insect is unavailable or nits are elsewhere from the pubic area. Entodermoscopy, provided that dermatologists have some knowledge of entomology, therefore promises advantages over standard microscopic examination.
人体虱（通常被称为“蟹”或“阴虱”）的诊断可能比其他类型的虱病（体虱和头虱）更困难，因为这种昆虫的身体更小，为 1.2x0.8 毫米，颜色可能更浅，活动性也较差，因此肉眼难以看到。皮肤镜检查能否有助于更好地分析皮肤？在两名患者中积累的临床经验给出了肯定的答案，此外还提供了昆虫及其卵的有用信息，这些信息为昆虫学家所熟知，但从未用于皮肤科诊断。活体鉴定可以将阴虱与其他皮肤征象区分开来，而帽瓣的圆锥形和卵对毛发的宽固定套则表明正在侵袭哪种虱子，即使昆虫不可用或卵不在阴毛区域。如果皮肤科医生对昆虫学有一定的了解，那么 Entomoscopy 有望优于标准显微镜检查。
