Conversely, a junctional nevus, which develops at the junction of the dermis and epidermis, is potentially cancerous.

There is also a hypothesis presented by researchers at Harvard and the University of Arkansas that maternal placenta embolizes to the fetal dermis during gestation resulting in hemangiomagenesis.

The epidermis is aneural and avascular, nourished by diffusion from the dermis, constituted at 95 % of keratinocytes but also containing melanocytes, Langerhans cells, Merkel cells, and inflammatory cells.

Bullous pemphigoid is an acute or chronic autoimmune skin disease, involving the formation of blisters, more appropriately known as bullae, at the space between the skin layers epidermis and dermis.

The donor site heals by re-epitheliasation from the dermis and surrounding skin and requires dressings.

Beneath this, the dermis comprises two sections, the papillary and reticular layers, and contains connective tissues, vessels, glands, follicles, hair roots, sensory nerve endings, and muscular tissue.

The dermis contains the ossicles ( bony plates ) which are rather loosely organised.

The body wall consists of an epidermis and a dermis and contains smaller calcareous ossicles, the types of which are characteristics which help to identify different species.

This usually produces a split-thickness skin graft, which contains the epidermis with only a portion of the dermis.

The dermis contains two vascular networks that run parallel to the skin surface — one superficial and one deep plexus — which are connected by vertical communicating vessels.

It contains larger blood vessels and nerves than those found in the dermis.

This organ is located in the dermis and maintains stem cells which not only re-grow the hair after it falls out, but also are recruited to regrow skin after a wound ;

A biopsy can be performed and may be helpful ; it reveals traumatized hair follicles with perifollicular hemorrhage, fragmented hair in the dermis, empty follicles, and deformed hair shafts ( trichomalacia ).

In the embryo, the epidermis, hair, and glands form from the ectoderm, which is chemically influenced by the underlying mesoderm that forms the dermis and subcutaneous tissues.

Hair is a filamentous biomaterial, that grows from follicles found in the dermis.

Eccrine sweat glands are smaller than apocrine sweat glands, and they do not extend as deep into the dermis.

Duchsustus is the animal's dermis, klaf is the epidermis, and gevil is both layers tanned unseparated.

* Nodule – A nodule is morphologically similar to a papule, but is greater than either 5 or 10 mm in both width and depth, and most frequently centered in the dermis or subcutaneous fat.

Stevens – Johnson syndrome ( SJS ) and toxic epidermal necrolysis ( TEN ) are two forms of a life-threatening skin condition, in which cell death causes the epidermis to separate from the dermis.

In these conditions, the naturally occurring largely commensal bacterium Propionibacterium acnes can cause inflammation, leading to inflammatory lesions ( papules, infected pustules, or nodules ) in the dermis around the microcomedo or comedone, which results in redness and may result in scarring or hyperpigmentation.

These are sometimes known as " epidermal ridges " which are caused by the underlying interface between the dermal papillae of the dermis and the interpapillary ( rete ) pegs of the epidermis.

T cells ( which normally help protect the body against infection ) become active, migrate to the dermis and trigger the release of cytokines ( tumor necrosis factor-alpha TNFα, in particular ) which cause inflammation and the rapid production of skin cells.

The mesoderm is found between the ectoderm and the endoderm and gives rise to somites, which form muscle ; the cartilage of the ribs and vertebrae ; the dermis, the notochord, blood and blood vessels, bone, and connective tissue.

* Dermatomal mesenchyme the dorsal portion of the paraxial mesoderm somite which gives rise to dermis

Soon after their formation, somites become subdivided into the dermomyotome dorsally, which gives rise to the muscles and dermis, and the sclerotome ventrally, which will form the spine components.

In pathology, it specifically refers to a sharp injury which damages the dermis of the skin.

Abrasions, which are wounds with intact skin ( non-penetration through dermis to subcutaneous fat ), usually require no active treatment except keeping the area clean, initially with soap and water.

Granuloma annulare is a skin disease of unknown cause in which granulomas are found in the dermis of the skin.

In pathology, it specifically refers to a sharp injury which damages the dermis of the skin.

The dermis is a layer of skin between the epidermis ( with which it makes up the cutis ) and subcutaneous tissues, that consists of connective tissue and cushions the body from stress and strain.

Apart from these cells, the dermis is also composed of matrix components such as collagen ( which provides strength ), elastin ( which provides elasticity ), and glycosaminoglycans.

Feelings of deep pressure ( from a poke, for instance ) are generated from Pacinian corpuscles ( the only other type of phasic tactile mechanoreceptor ), which are located deeper in the dermis, and some free nerve endings.

The somites are epithelial spheres that contain the precursors of the vertebrae, the ribs, the skeletal muscles of the body wall and limbs, and the dermis of the back.

Micrograph showing full thickness epidermal necrosis with a basket weave-like stratum corneum and separation of the dermis and Epidermis ( skin ) | epidermis.

Most burns affect only the skin ( epidermal tissue and dermis ).

Electron microscopic analysis of the epidermal basement membrane zone ( BMZ ) reveals that it comprises a narrow and sometimes folded interface between the basal keratinocytes and the dermis.

For example, carcinoma in situ of the skin, also called Bowen's disease, is the accumulation of neoplastic epidermal cells within the epidermis only, that has failed to penetrate into the deeper dermis.

" Epidermal inclusion cyst " more specifically refers to implantation of epidermal elements into the dermis.

In many other cell types, such as cells of the dermis, keratin filaments and other intermediate filaments function as part of the cytoskeleton to mechanically stabilize the cell against physical stress.

** Junctional nevus: the nevus cells are located along the junction of the epithelium and the underlying dermis.

** Intradermal nevus: the nevus cells are located in the dermis only.

The nevus cells are spindle shaped and scattered in deep layers of the dermis.

Because the cells of Bowen's disease have not invaded the dermis, it has a much better prognosis than invasive squamous cell carcinoma.

The dermis is composed of three major types of cells:

The blue colour is caused by melanocytes, melanin-containing cells, that are usually located in the epidermis but are in the deeper region of the skin known as the dermis in the location of the spot.

The skin lesions of urticarial disease are caused by an inflammatory reaction in the skin, causing leakage of capillaries in the dermis, and resulting in an edema which persists until the interstitial fluid is absorbed into the surrounding cells.

The epidermis is composed of the outermost layers of cells in the skin, " epi " in Greek meaning " over " or " upon ", which together with the dermis forms the cutis.

The mesoderm forms: skeletal muscle, the skeleton, the dermis of skin, connective tissue, the urogenital system, the heart, blood ( lymph cells ), the kidney, and the spleen.

A biopsy of the lesions will show extravasated erythrocytes within dermal papillae and dyskeratotic cells within the dermis.

* Leukemia cutis, describing infiltration of the dermis ( skin ) by leukemic cells, which is also referred to as cutaneous granulocytic sarcoma.

Cells expressing CD34 ( CD34 + cell ) are normally found in the umbilical cord and bone marrow as hematopoietic cells, a subset of mesenchymal stem cells, endothelial progenitor cells, endothelial cells of blood vessels but not lymphatics ( except pleural lymphatics ), mast cells, a sub-population dendritic cells ( which are factor XIIIa negative ) in the interstitium and around the adnexa of dermis of skin, as well as cells in soft tissue tumors like DFSP, GIST, SFT, HPC, and in to some degree also in MPNSTs etc.
