Epistasis01:39

Epistasis

In addition to multiple alleles at the same locus influencing traits, numerous genes or alleles at different locations may interact and influence phenotypes in a phenomenon called epistasis. For example, rabbit fur can be black or brown depending on whether the animal is homozygous dominant or heterozygous at a TYRP1 locus. However, if the rabbit is also homozygous recessive at a locus on the tyrosinase gene (TYR), it will have an unshaded coat that appears white, regardless of its TYRP1...
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...
Changes in Skin Color: Clinical Perspectives01:14

Changes in Skin Color: Clinical Perspectives

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.
Albinism
Albinism is a genetic disorder that affects (completely or partially) the coloring of skin, hair, and eyes. The defect is primarily...
Photoreceptors and Visual Pathways01:22

Photoreceptors and Visual Pathways

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, whereas...
Disorders of Erythrocytes01:27

Disorders of Erythrocytes

Disorders of erythrocytes, or red blood cells (RBCs), include a range of conditions affecting their number, shape, or function.
Erythrocyte disorders can be broadly categorized into two main types: anemic and polycythemic conditions.
A low oxygen-carrying capacity of the blood due to the loss, lower production, or destruction of erythrocytes is termed anemia. Hemorrhagic anemia, for example, occurs when bleeding from an external wound or internal ulcer reduces erythrocyte counts.
On the other...
Jaundice01:25

Jaundice

Jaundice, or icterus, is the yellow discoloration of the skin, sclerae, and mucous membranes. It happens when plasma bilirubin levels rise above 2.5-3 mg/dL, leading to bilirubin deposition in tissue.Bilirubin is a byproduct of hemoglobin degradation. In macrophages, hemoglobin breaks down into globin and heme. Globin is converted into amino acids, while heme is turned into biliverdin by heme oxygenase, which is then reduced to unconjugated bilirubin by biliverdin reductase.Unconjugated...

Summary
This summary is machine-generated.

A rare case of systemic argyria, or silver poisoning, was diagnosed post-mortem in a 74-year-old man. This condition, marked by silver pigment deposition, presented diagnostic challenges for clinicians and pathologists.

Area of Science:

  • Medicine
  • Pathology
  • Toxicology

Background:

  • Systemic argyria is a rare condition resulting from chronic silver compound ingestion.
  • It is generally considered benign, with primarily cosmetic effects and no known carcinogenic potential.

Observation:

  • A 74-year-old male presented with symptoms of cardiac failure and severe skin discoloration, initially presumed to be cyanosis.
  • Post-mortem examination revealed widespread silver pigment deposition in multiple organs, including the skin.
  • The patient had a co-existing gastric malignant neuroendocrine tumor and no reported history of silver compound exposure.

Findings:

  • The autopsy confirmed systemic argyria, characterized by significant silver deposition.
  • The presence of argyria alongside a neuroendocrine tumor and bronchopneumonia complicated the clinical and pathological diagnosis.

Implications:

  • This case highlights the diagnostic challenges posed by systemic argyria, particularly when presenting with unusual symptoms or co-existing conditions.
  • It underscores the importance of considering iatrogenic or environmental exposures in differential diagnoses, even in the absence of a clear history.
  • Further research may be needed to fully understand the long-term effects and potential associations of systemic argyria.
