Papillary Dermis01:11

Papillary Dermis

3.1K
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

4.3K
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...

Peripheral Arterial Disease II: Clinical Manifestations and Diagnostic Evaluation

23
Clinical manifestationsPeripheral Arterial Disease (PAD) manifests through a range of symptoms, from the characteristic intermittent claudication to atypical presentations and severe complications in advanced stages. Intermittent claudication, a hallmark symptom of PAD, presents as exercise-induced muscle pain that typically resolves within minutes of rest. This pain is reproducible and stems from inadequate blood flow, leading to the accumulation of lactic acid produced during anaerobic...

Area of Science:

  • Genetics
  • Dermatology

Background:

  • Palmoplantar keratoderma (PPK) encompasses inherited and acquired disorders causing skin thickening on palms and soles.
  • Punctate PPK (PPPK) is an inherited condition with autosomal dominant inheritance, linked to chromosomal loci 8q24.13-8q24.21 and 15q22-15q24.
  • Type 1 PPPK (Buschke-Fischer-Brauer disease) involves loss-of-function mutations in the AAGAB or COL14A1 genes.

Observation:

  • The study presents the clinical presentation of a patient with PPPK.
  • Genetic analysis was performed to investigate the underlying cause.

Findings:

  • The patient's features were most consistent with type 1 PPPK.
  • This case contributes to understanding the genetic basis of PPPK.

Implications:

  • Further research into AAGAB and COL14A1 gene mutations in PPPK is warranted.
  • Understanding the genetic landscape of PPPK can aid in diagnosis and potential therapeutic strategies.
