Clinical Applications of Epidermal Stem Cells01:19

Clinical Applications of Epidermal Stem Cells

3.1K
Epidermal stem cells (EpiSCs) are mainly located at the basal layer of the epidermis. These cells repair minor injuries of the skin and replace dead skin cells. However, EpiSCs’ cannot heal severe wounds such as major burns or those from diabetes or hereditary disorders. In such cases, culturing the epidermal stem cells from the patient is possible and has yielded successful treatment options, such as laboratory-grown skin grafts. These grafts are synthesized using a patient’s own...

Accessory Structures of the Skin: Sebaceous Glands01:21

Accessory Structures of the Skin: Sebaceous Glands

3.6K
A sebaceous gland is a type of oil gland found almost all over the skin ( except palms and soles) and helps lubricate and waterproof the skin and hair. Most sebaceous glands are associated with hair follicles. They generate and excrete sebum, a mixture of lipids, onto the skin surface, thereby naturally lubricating the dry and dead layer of keratinized cells of the stratum corneum, keeping it pliable.
These glands that produce the oils on the skin and hair are holocrine glands. The mature...

Papillary Dermis

5.2K
Dermis
The dermis might be considered the "core" of the integumentary system, as distinct from the epidermis and hypodermis. It contains blood and lymph vessels, nerves, and other structures, such as hair follicles and sweat glands. The dermis is made of two layers of connective tissue that comprise an interconnected mesh of elastin and collagenous fibers, produced by fibroblasts.
Papillary Layer
The papillary layer is made of loose, areolar connective tissue, which means the collagen...

Skin Cancer01:30

Skin Cancer

5.6K
Skin cancer is a type of cancer that occurs when there is an abnormal growth of skin cells, usually triggered by damage to the DNA within the skin cells. It is primarily caused by exposure to ultraviolet (UV) radiation from the sun or artificial sources like tanning beds. Skin cancer is the most common type of cancer worldwide, and its incidence continues to rise.
Basal Cell Carcinoma (BCC): BCC is the most common type of skin cancer, accounting for about 80% of cases. It typically develops in...

Multipotency and Niche of Bulge Stem Cell01:06

Multipotency and Niche of Bulge Stem Cell

4.1K
A hair follicle or HF is a small part of the skin that produces the hair shaft. Paul Gerson Unna was the first to observe a bulge in the human hair follicle's outer root sheath (ORS). The bulge is present between the sebaceous gland and the arrector pili muscle and is the niche for hair follicle stem cells (HFSCs). The bulge is also a niche for melanocyte stem cells, and their loss results in graying of hair. The HFSCs express Sox9 and Lhx2, which help them maintain stemness and prevent...

Accessory Structures of the Skin: Hair and Hair Follicles

4.0K
Hair and hair follicles are integral components of the integumentary system. Hair is a filamentous structure composed mainly of a protein called keratin. It is found on the surface of the skin throughout the body, except for areas such as the palms of the hands and soles of the feet.
Hair is a keratinous filament growing out of the epidermis. It is primarily made of dead, keratinized cells. Hair strands originate at the epidermal penetration called the hair follicle. The hair shaft is the part...

Summary

Barbed thread lifting can rarely cause chronic epidermal inclusion cysts. This case highlights a rare complication requiring surgical excision, emphasizing the importance of considering iatrogenic causes.

Area of Science:

  • Dermatology
  • Plastic Surgery
  • Aesthetic Medicine

Background:

  • Barbed thread lifting is a popular minimally invasive cosmetic procedure known for its ease of use and lower complication rates compared to traditional surgical facelifts.
  • While generally safe, rare complications can occur, necessitating further investigation into potential adverse events associated with the materials used.

Observation:

  • A 61-year-old woman presented with a two-year history of recurrent inflammation, scarring, and discharge in the temporal area.
  • The patient had undergone barbed thread lifting four years prior to symptom onset.
  • Imaging revealed soft tissue infiltration, and surgical exploration identified a multi-directional barbed thread embedded in scar tissue.

Findings:

  • Histopathological examination confirmed the presence of an epidermal inclusion cyst and polydioxanone suture material.
  • The epidermal inclusion cyst was determined to be iatrogenically induced, directly related to the previous barbed thread lifting procedure.

Implications:

  • This case underscores a rare but significant complication of barbed thread lifting, specifically the formation of chronic epidermal inclusion cysts.
  • The findings suggest that retained suture material from barbed thread lifts can act as a nidus for cyst formation, requiring complete excision for resolution.
  • Clinicians should consider iatrogenic causes, such as retained barbed threads, when diagnosing chronic inflammatory conditions or cyst formation in patients with a history of such procedures.
