This week's case features some immature insects submitted in a sterile collection cup with balled up tissues inside. The patient is a middle-aged female, and no source or clinical information is provided 🫤.
Looking closely, 3 tiny brown specs ~ 1mm in size could be seen through the cup using the dissecting microscope. Our lab staff are rightly cautious about opening containers when tissue or other material obscures the contents in case there is something alive and/or contagious inside!

This looks like Lone Star Ticks. Size suggests adults
Louse nymphs
Correct me if I’m wrong! These resemble mites, and if I am correct they are nymphs of chicken mites. Of course they are not itch mites, yet they do bite and will make you itch. Try venturing into an unsanitary chicken coop for an unwelcome experience. Again what do I know besides the mighty itch mites especially in crowded environments like prisons and nursing homes.

Lice is my guess
Upon more review, I am more inclined towards baby Pediculus humanus capitis.

Pediculus nymphs. If from the scalp, they're head lice. If from the body or clothing, body lice.
Nymphs of Pediculus humanus (P. humanus capitis or P. humanus humanus)
Larval human body louse
Sorry, nymph, not larva
Mite? /Patrik
Morphologically, it is not mite. Mite has 8 legs with body form like a sac (an acarina). This is a louse, Pediculus sp. the thoracic muscle (which is not clearly shown) may differentiate between pediculus humanus capitis (head lice) and pediculus humanus corporis (body lice)
