Normal Skin Histology - Explained by a Dermatopathologist

[@JMGardnerMD]

A complete organized library of all my videos, digital slides, pics, & sample pathology reports is available here: kikoxp.com/posts/5084 (dermpath) & kikoxp.com/posts/5083 (bone/soft tissue sarcoma pathology). Also, 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. Sorry about that!

[@kanvalImran]

Jerad Gardner, MD yes I thought so too thanks for correcting.. u usually keep the arrow to point out minor structures plz keep arrows pointing on each structure to make it more clear.sometimes the arrow is lost..thanks so much for wonderful videos

[@Vlad_Kowach]

Спасибо за ваш труд (Thank you for your work.)

[@stephanieys9349]

Thank you so much!!

[@System9down]

Hey, Doctor Jerad. How are you? I'm from Brasil and I have a channel on youtube. Could I use this video, without the audio, to explain the skin? I mean, I just want the images of the tissues, I will take off your voice and I will explain this all in my voice. I'll put the creditis down bellow the video and a link for your channel and this video. What do you say?

[@GregorMortis420]

Dude, you displayed a shit ton of notions/informations, how are we supposed to judge you from this small mistake? XD

[@fernandovet]

I am a professor of pathology in Brazil. I always watch your videos, because it is a mirror where I can try to level myself. You have a didactic talent, showing in a simple and direct way how it works and how our body is attacked. Congratulations.

[@JMGardnerMD]

[@mariajoao5261]

I'm a medical student in Portugal and I could not be more grateful for your effort. It enabled me not just to learn some concepts that will be essential for my studies, but also allowed me to start liking this. It is amazing to learn all this material by listening to your explanations rather than reading a book and finding all this boring, when it is great fun. Thanks, Sir. 😊

[@burhanemregurdal2502]

I am a Turkish medical student and i want to thank you for bringing this amazing video. Its really better than other videos, showing us whole content in a video directly from microscopic view is truely educational.

[@chrysastamou5528]

Mr. Gardner, I am really excited that I can finally attend your video! So happy to find that there are closed subtitles, it was very difficult for me to attend the video without subtitles because of my hearing impairment. Thus, I would like to thank you and the volunteer medical student Abigail Cline for the amazing work. Thank you very much!

[@JMGardnerMD]

My pleasure. More subtitles are in the works currently.

[@missknowall]

Went through the whole video once again. It is so packed with "pearls of wisdom" that every time I see it, I get something new out of it. So thanks once again Dr Jerad Gardner.

[@JMGardnerMD]

[@davebrodhead6315]

Thank you for publishing these! I am a beginning A&P student. Histology is brand new to me and I was struggling to find it relevant to put in the time to figure it out. I found your videos on synovial sarcoma. My cousin (same age) passed over 10 years ago from synovial sarcoma so that video anchored my learning to something that I care about, but many concepts went over my head (which is great since you made me curious). Then I found this video which is really bringing alive the concepts I am learning in class. THANK YOU!

[@renatalp]

WHAT A LECTURE! WOW! I've studied histology in biology school, for 2 years now in medical school, and never have i ever seen the skin explained so thoroughly and so well. I'm currently studying the histology of skin carcinomas and i thought I'd go back a little and refresh my memory on what normal looks like and found your video. man, it's the basics! and i didn't know that i didn't know shit about the basics. NOW I know the basics, thanks to you! so grateful! and so wowed! thank you!

[@priyankakale7741]

You channel is awesome for any pathologist esp in derm and bone soft tissue pathology. I no more find it difficult as it used to be for me. You way of showing no.of cases gives a lot more confidence about the tumors. Your way of teaching the aproach to see any slide is soo good. Thank you so much.

Thank you Dr. Gardner for this incredible video. You have such a gift for making the difficult, easy and the boring, interesting. I know that you are a dermatopathologist but do you have any other organ systems?

[@JMGardnerMD]

Thank you! I also have cartilage and Bone Histology videos on my channel with special guest Andrew Rosenberg. I hope to get my colleague Jeanette Ramos to come back and do a normal bone marrow video with me. I have also been thinking about doing very basic Histology of other organs. Not in depth like this skin one, but basically “how to figure out what you’re looking at” beginner Histology video. Do you think that would be useful for people?

[@drjsteinberg]

Jerad Gardner yes, a video or series demonstrating how to tell which tissue we are looking at would be very helpful. Other than thyroid 😀

[@ncorry8491]

Another fantastic video

[@woloabel]

I muse immensely on the immunohistopathology staining (S100, Keratin, SOX100, CD31, CD34 etc). Not only are these molecules essential to mounting a competent immune response, but they too are used, as herein, to illustrate and elucidate a vastly bland and monotonous Histology otherwise ie Hematoxylin and Eosin Staining (HE) shortcomings. Immunoglobulins are a revolutionary way of performing medicine, as they too have become evidently therapeutic as in Monoclonal Antibodies (Dr Gardner's Smart Bombs). I just can not have enough of these structures. Maybe I revel in them so much that I will just develop a Multiple Myeloma (MM) just for enlightment, just kidding...lol

*Normal Skin Histology: A Comprehensive Guide* * *0:10** Epidermis Layers:* The epidermis, the skin's outermost protective layer, consists of several layers: * *Stratum basale (Basal Layer):* The deepest layer where new squamous cells (keratinocytes) are produced. * *Stratum spinosum (Spinous Layer):* Characterized by desmosomes, which appear as spines connecting keratinocytes. * *Stratum granulosum (Granular Layer):* Contains keratohyalin granules, contributing to cell death and the formation of the stratum corneum. * *Stratum corneum (Corneal Layer):* The outermost layer composed of dead, flattened keratinocytes that continuously shed. * *Stratum lucidum:* A thin, translucent layer found only in acral skin (palms and soles) and chronically rubbed skin. * *5:16** Melanocytes vs. Keratinocytes:* * *Melanocytes:* Produce melanin pigment and transfer it to keratinocytes for UV protection. Appear as gray cells with a clear halo (artifact of processing). * *Keratinocytes:* The primary cells of the epidermis, containing keratin filaments that provide strength and structure. Have a clear halo around the nucleus. * *10:10** Langerhans Cells:* Immune cells located in the stratum spinosum. They capture antigens and present them to the immune system. Have a bean-shaped nucleus. * *11:50** Dermis Structure:* The dermis, the supporting layer beneath the epidermis, consists of: * *Papillary Dermis:* The upper layer with fine collagen fibers and dermal papillae, which contain blood vessels for nourishing the epidermis. * *Reticular Dermis:* The thicker, lower layer with dense collagen bundles and larger blood vessels. * *15:25** "Empty" Spaces on Slides:* White spaces on slides represent: * *Vascular Channels:* Lined by a single layer of endothelial cells. * *Glands/Ducts/Cysts:* Lined by epithelium (usually thicker than endothelium). * *Artifact:* Tears, folds, or areas where substances (like fat) have been dissolved during processing. * *18:24** Blood Vessels & Nerves:* * *Blood Vessels:* Supply nutrients and oxygen to the skin. Arteries have a thick muscular wall with an internal elastic lamina. * *Nerves:* Often run alongside blood vessels (neurovascular bundles). Contain axons, Schwann cells, and a protective perineurium. * *20:00** Arrector Pili Muscles:* Smooth muscle bundles responsible for making hair stand erect (goosebumps). * *21:10** Sebaceous Glands:* Produce sebum (oil) that lubricates the skin and hair. Sebocytes (sebaceous cells) contain lipid droplets, appearing as clear vacuoles. * *23:14** Hair Follicle Anatomy:* * *Hair Bulb/Matrix:* The base of the follicle where hair growth originates. Contains actively dividing cells. * *Inner Root Sheath:* Surrounds the developing hair shaft. Contains trichohyaline granules. * *Outer Root Sheath:* A clear layer due to the presence of glycogen. * *Hair Shaft:* The visible part of the hair, composed of compacted, dead keratinized cells. * *Isthmus:* The area where the sebaceous gland duct enters the follicle. * *Infundibulum:* The upper portion of the follicle, resembling the epidermis. * *24:45** Eccrine Sweat Glands:* Produce watery sweat for thermoregulation. Have a coiled structure (eccrine coil) and a duct leading to the skin surface. * *27:20** Glands vs. Blood Vessels:* Eccrine sweat gland ducts have a double layer of cuboidal epithelial cells, while blood vessels are lined by a single layer of endothelial cells. * *27:50** "Pink Bundles":* * *Smooth Muscle:* Found in arrector pili muscles and blood vessel walls. * *Nerve:* Characterized by axons, Schwann cells, and perineurium. * *Dense Connective Tissue:* Found in tendons, fascia, and ligaments. * *29:37** Acral Skin and Contact Dermatitis:* * *Parakeratosis:* Retention of nuclei in the stratum corneum, indicating irritation or abnormal growth. * *Perivascular Lymphocytes:* Inflammatory cells surrounding blood vessels. * *Spongiosis:* Edema (fluid) within the epidermis, causing separation of keratinocytes and highlighting desmosomes. * *34:20** Stratum Lucidum:* Normally found in acral skin, appears as a pale line beneath the stratum corneum. * *35:40** Glomus Body:* A specialized structure in acral skin involved in temperature regulation. Composed of a blood vessel surrounded by modified smooth muscle cells (pericytes). * *37:55** Subcutis and Adipose Tissue:* The subcutis lies beneath the dermis and contains fat cells (adipocytes). Adipocyte nuclei may show a "lockhern" (nuclear lake), a clear space representing dissolved lipid. * *50:40** Pacinian Corpuscle:* A sensory receptor for deep pressure and vibration, located in the deep dermis and subcutis. Has a distinctive onion-like appearance. * *1:02:28** Meissner Corpuscle:* A sensory receptor for fine touch, located in the papillary dermis of acral skin. Has an oval shape with internal lines. * *53:00** Dense Regular Connective Tissue:* Composed of dense collagen bundles and fibroblasts. Found in tendons, ligaments, and fascia. Can be distinguished from smooth muscle by the presence of extracellular collagen bundles. * *55:33** Immunohistochemistry Highlights:* * *Cytokeratin:* Stains epithelial cells, highlighting the epidermis, hair follicles, and sweat glands. * *S100:* Stains melanocytes, Langerhans cells, and adipocytes. * *Desmin:* Stains smooth muscle cells, highlighting arrector pili muscles and blood vessel walls. * *CD31:* Stains endothelial cells lining blood vessels. * *SOX-10:* Stains melanocyte nuclei. * *1:04:10** Digit Histology:* Amputated toe specimens demonstrate acral skin, bone, tendons, arteries, and the nail matrix (where nail growth occurs). * *1:11:50** Solar Elastosis:* Accumulation of blue-gray elastic fibers in the dermis due to chronic sun exposure.

Sorry I cannot. I still find alopecia very difficult and I am not equipped with the skill or knowledge to teach this subject.

[@donadamov]

Why is it, that biopsies from legs/arms/hands/feet are considered as less useful for histology? I have heard this several times, but never gotten an explanation. Great work, thank you!

[@JMGardnerMD]

I have never heard that as a general rule. I think totally depends on the clinical situation. The dermatologist has to biopsy where the skin is abnormal. For rashes, it is preferable to avoid the lower leg (especially in older adults) when possible, because the venous stasis changes on the lower leg can complicate the pathology appearance (and the wound can have delayed healing). But if the rash is limited to the legs, then there is no where else to biopsy.

[@Perfectly_imperfect2]

I wish u could make more histology videos for undergraduate medical students .Histology is my least favorite because I don't understand anything I see.This is the first time I actually understand the stuff and actually I learned why a doctor should learn histology.If u have time please make more videos for medical students about basic histology.😢❤
