Summary
A rare skin condition, Wolf's postherpetic isotopic response, can develop after herpes zoster infection. Early recognition and vaccination are key to preventing such complications.
Area of Science:
- Dermatology
- Virology
- Pathology
Background:
- Herpes zoster, commonly known as shingles, is caused by the varicella-zoster virus reactivation.
- Postherpetic complications can manifest in various ways, affecting the skin and nervous system.
Observation:
- A 66-year-old male presented with hyperkeratotic plaques on his cheek and temple.
- The patient had a recent history of herpes zoster affecting the trigeminal nerve.
Findings:
- A shave biopsy confirmed the lesions as postherpetic hyperkeratosis.
- This presentation is identified as Wolf's postherpetic isotopic response, a novel skin disorder at a prior herpes zoster site.
Implications:
- This case highlights an unusual complication of herpes zoster, emphasizing the need for increased clinical awareness.
- Vaccination against herpes zoster is crucial for preventing potential post-infection dermatological sequelae.

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.

01:15Reticular Dermis
4.2K
The papillary and reticular dermis are the two layers of the dermis. They are made of connective tissue with fibers of collagen extending from one to the other, making the border between the two somewhat indistinct. The dermal papillae extending into the epidermis belong to the papillary layer, whereas the dense collagen fiber bundles below belong to the reticular layer.
Reticular Layer
Underlying the papillary layer is the much thicker reticular layer, composed of dense, irregular connective...

01:21Accessory Structures of the Skin: Sebaceous Glands
3.5K
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...

01:02Hypodermis
7.0K
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...

01:24Cells of the Epidermis
6.4K
The epidermis is made of four or five layers of epithelial cells, depending on its location in the body. From deep to superficial, these layers are the stratum basale, stratum spinosum, stratum granulosum, stratum lucidum, and stratum corneum.
The cells in all these layers except the stratum basale are called keratinocytes, a type of cell that manufactures and stores the protein keratin. The keratinocytes in the stratum corneum are dead and regularly slough away, being replaced by cells from...

4.0K
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...
