Papillary Dermis01:11

Papillary Dermis

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 and...
Reticular Dermis01:15

Reticular Dermis

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...
Pigmentation01:19

Pigmentation

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...

Summary

This case report details a 9-year-old girl presenting with numerous hyperpigmented and hypopigmented macules on her hands and neck. These skin lesions have been present since childhood, highlighting a chronic dermatological condition.

Area of Science:

  • Dermatology
  • Pediatric Medicine
  • Clinical Case Reports

Background:

  • Skin pigmentation disorders can manifest in various forms.
  • Macular lesions, characterized by flat spots, are common dermatological findings.
  • Congenital or childhood-onset skin conditions require careful evaluation.

Purpose of the Study:

  • To report a clinical case of a pediatric patient with a specific pattern of skin macules.
  • To document the presentation of hyperpigmented and hypopigmented macules since childhood.
  • To contribute to the understanding of rare or atypical dermatological presentations in children.

Main Methods:

  • Clinical observation and patient history.
  • Dermatological examination focusing on lesion morphology and distribution.

  • Documentation of lesion characteristics including color (hyperpigmented and hypopigmented) and location (hands and neck).

    • Main Results:

    • A 9-year-old female patient presented with multiple macules.
    • Lesions exhibited variations in pigmentation, appearing both darker (hyperpigmented) and lighter (hypopigmented).
    • The affected areas were primarily the hands and neck, with lesions noted since childhood.

    Conclusions:

    • The case highlights a persistent, likely congenital or early-onset, condition affecting skin pigmentation.
    • The distinct presentation of both hyperpigmented and hypopigmented macules warrants further investigation into potential underlying causes.
    • This report underscores the importance of detailed clinical documentation for pediatric dermatological cases.
