Accessory Structures of the Skin: Hair and Hair Follicles01:16

Accessory Structures of the Skin: Hair and Hair Follicles

2.4K
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...

Hypodermis01:02

Hypodermis

4.7K
The hypodermis (the subcutaneous layer or superficial fascia) is present directly below the dermis. It connects the skin to the underlying fascia (fibrous tissue) of the bones and muscles. It is not strictly a part of the skin, although the border between the hypodermis and dermis can be difficult to distinguish. The hypodermis consists of well-vascularized, loose, areolar connective tissue and adipose tissue, which functions as a mode of fat storage and provides insulation and cushioning for...

Accessory Structures of the Skin: Hair Growth and Types

1.5K
Hair growth begins with the production of keratinocytes by the basal cells of the hair bulb. As new cells are deposited at the hair bulb, the hair shaft is pushed through the follicle toward the surface. Keratinization is completed as the cells are pushed to the skin surface to form the shaft of hair that is externally visible. The external hair is completely dead and composed entirely of keratin. Hair can be cut or shaven without damaging the hair structure because the cut is superficial. Most...

The Mammary Glands01:12

The Mammary Glands

721
The female breast is a hemispheric projection of variable size positioned anterior to the pectoralis major and serratus anterior muscles. A fascia layer composed of dense, irregular connective tissue connects it to these muscles.
Each breast features a pigmented projection known as the nipple, through which milk emerges via closely spaced openings of ducts, referred to as lactiferous ducts. Surrounding the nipple is a circular pigmented area of skin named the areola, which appears rough due to...

Papillary Dermis01:11

Papillary Dermis

3.0K
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...

Multipotency and Niche of Bulge Stem Cell01:06

Multipotency and Niche of Bulge Stem Cell

3.7K
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...

Summary
This summary is machine-generated.

Caterpillar hair can cause serious eye conditions, including anterior uveitis and high intraocular pressure, mimicking Posner-Schlossman syndrome. Prompt identification and removal of foreign bodies are crucial for managing these unusual ocular presentations.

Area of Science:

  • Ophthalmology
  • Toxicology
  • Medical Case Reports

Background:

  • Anterior uveitis, iris neovascularization, and elevated intraocular pressure are common ophthalmic conditions.
  • Posner-Schlossman syndrome is characterized by recurrent episodes of unilateral anterior uveitis with secondary glaucoma.
  • Ocular inflammation can also result from exposure to foreign bodies, including environmental irritants.

Purpose of the Study:

  • To present a unique case of ocular inflammation and elevated intraocular pressure caused by subconjunctival and intraocular caterpillar hair.
  • To highlight the diagnostic challenges posed by caterpillar hair mimicking Posner-Schlossman syndrome.

Main Methods:

  • A case report detailing the clinical presentation, diagnostic workup, and management of a patient with ocular symptoms.
  • Surgical intervention (trabeculectomy) was performed, during which foreign bodies were identified and removed.

Main Results:

  • A 30-year-old male presented with blurred vision and colored haloes, diagnosed with Posner-Schlossman syndrome due to anterior uveitis and high intraocular pressure.
  • Fundus examination revealed peripheral retinal hemorrhages, vasculitis, and capillary non-perfusion.
  • Caterpillar hairs were discovered in the conjunctiva during surgery and a seta was found in the vitreous.

Conclusions:

  • This case demonstrates an atypical presentation where caterpillar hair mimicked Posner-Schlossman syndrome.
  • Early recognition and removal of caterpillar hair are essential to prevent severe ocular complications and misdiagnosis.
