The basic normal structures of the skin discussed and described by a dermatopathologist. This material is intended for use by medical students, junior pathology or dermatology residents, or for anyone else studying normal human histology. Special thanks to two of my medical students at UAMS for helping make this video possible. Miki Lindsey convinced me that I really needed to sit down and record this video. Akash Patel took time to edit the video and make it ready for YouTube. My sincere thanks to both of them for helping me overcome procrastination.
Huge thanks to Abigail Cline, a medical student at Medical College of Georgia, for volunteering to type a transcript of this ENTIRE video (over 14,000 words!) so that I could provide closed caption subtitles for those with hearing impairments and for those who may need assistance in understanding spoken English (particularly given how quickly I speak!). You can access a text version of her transcript of my video here: https://kikoxp.com/posts/5390
Correction - I made a mistake in the video. I said that sebaceous gland secretions are turned into smelly substances by bacteria and that this makes body odor. That is incorrect. That is actually true of APOCRINE gland secretions not sebaceous secretions.
Also, in the past I used "keratinocyte" and "squamous cell" interchangeably (this is because in dermatopathology, we see and talk about squamous cell carcinomas all the time, and those tumors are composed of keratinocytes). But technically, in normal skin histology, "squamous cell" refers only to the flattened keratinocytes in the superficial epidermis. Thankfully, a histology PhD colleague pointed this out to me and corrected my lazy nomenclature!

An abscess is an infectious process characterized by a collection of pus surrounded by inflamed tissue. [1, 2] Abscesses can form anywhere in the body, from a superficial skin (subcutaneous) abscess to deep abscesses in muscle, organs, or body cavities. Patients with subcutaneous skin abscesses present clinically as a firm, localized, painful, erythematous swelling that becomes fluctuant (see the image below).

Liposuction in tummy tuck requires special planning and technique. I need to ensure that the blood circulation is well maintained for good healing. Yet proper liposuction is important to have a nice flat and contoured tummy.

A Pap smear (also called a Pap test) is a screening procedure for cervical cancer. It tests for the presence of precancerous or cancerous cells on the cervix, the opening of the uterus. It's named after the doctor who determined that this was a useful way to detect signs of cervical cancer.
