Summary
Reticulated hyperpigmentation, a lacy skin pattern, is rarely seen on the scalp. This case report highlights lichen planopilaris (LPP) as a potential cause in darker-skinned individuals.
Area of Science:
- Dermatology
- Clinical Case Reports
Background:
- Reticulated hyperpigmentation presents as a rare, net-like brown skin discoloration.
- Scalp involvement is typically excluded from the differential diagnosis of this dermatologic pattern.
Observation:
- A case of lichen planopilaris (LPP) presenting with reticulated hyperpigmentation on the scalp is described.
- The patient was a Black man with this unusual presentation.
Findings:
- Lichen planopilaris (LPP) can manifest as reticulated hyperpigmentation on the scalp.
- This presentation is particularly relevant in individuals with darker skin tones.
Implications:
- Clinicians should consider lichen planopilaris (LPP) in the differential diagnosis of scalp reticulated hyperpigmentation.
- The diagnostic approach for reticulated hyperpigmentation may need to be expanded to include the scalp, especially in darker-skinned populations.

3.5K
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.

Underlying the papillary layer is the much thicker reticular layer, composed of dense, irregular connective...

3.4K
The color of the skin is influenced by a number of pigments, including melanin, carotene, and hemoglobin. Recall that melanin is produced by cells called melanocytes, which are found scattered throughout the stratum basale of the epidermis. The melanin is transferred to the keratinocytes via melanosomes.
Melanin occurs in two primary forms: eumelanin that provides black and brown pigment and pheomelanin that provides red color. Dark-skinned individuals produce more melanin than those with pale...

6.8K
At the molecular level, visual signals trigger transformations in photopigment molecules, resulting in changes in the photoreceptor cell's membrane potential. The photon's energy level is denoted by its wavelength, with each specific wavelength of visible light associated with a distinct color. The spectral range of visible light, classified as electromagnetic radiation, spans from 380 to 720 nm. Electromagnetic radiation wavelengths exceeding 720 nm fall under the infrared category,...

The first thing a clinician sees is the skin, so the examination of the skin should be part of any thorough physical examination. Most skin disorders are relatively benign, but a few, including melanomas, can be fatal if untreated. A couple of the more noticeable disorders, albinism and vitiligo, affect the appearance of the skin and its accessory organs.

Skin is the first line of defense and encounters a variety of microbes. Some pathogenic strains are often the cause of a broad range of infections of the skin and other body systems. These conditions can affect people of all ages and may have different causes, including genetic factors, infections, autoimmune reactions, environmental factors, and lifestyle choices.
Gram-positive Staphylococcus spp. and Streptococcus spp. are responsible for many of the most common skin infections. However, many...

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...
