case_images: Examination revealed multiple ill-defined small erythematous papules with few excoriations on the face, chest, abdomen, back, upper and lower extremities, and pubic region, and some pustules present on the chest and face [Figure 1a]. There were brownish-gray macules chiefly on the upper thighs- maculae cerulae [Figure 1b].
case_images: Dermoscopy from the scalp (a), Eyelash (b), Chest (c) and pubic region (d). Brownish crab-like louse clutching on the hair and the skin surface- Phtirus pubis (white arrow), maculae cerulae (orange arrow), transparent whitish crystalline structure devoid of operculum - empty nits (green arrow), ovoid brown structure - active viable nits (blue arrow), nymph (yellow arrow)

case_images: Dermoscopy of the lice on the scalp, face, body, and pubic region [Figure 2] with showed semitransparent whitish crab-like lice with three pairs of legs where the distal two pairs had pincer-like claws clutching on the hair as well as stuck on the skin surface [Figure 3a].

case_images: Dermoscopy of the lice on the scalp, face, body, and pubic region [Figure 2] with showed semitransparent whitish crab-like lice with three pairs of legs where the distal two pairs had pincer-like claws clutching on the hair as well as stuck on the skin surface [Figure 3a]. Numerous viable nits which were dark brown in color and convex in shape [Figure 3b] were presently attached to the hairs along with a few transparent empty crystalline nits [Figure 3c]. Nymphs smaller in size [Figure 3d] than the adult lice along with hemorrhagic red dots suggestive of the lice bite were present.
case_images: Lice removed from scalp, chest, and pubis when observed under the USB dermoscope. (a) and microscope. (b) All were crab-like short-bodied organisms suggestive of Pthirus pubis
