Oogenesis02:07

Oogenesis

71.3K
In human women, oogenesis produces one mature egg cell or ovum for every precursor cell that enters meiosis. This process differs in two unique ways from the equivalent procedure of spermatogenesis in males. First, meiotic divisions during oogenesis are asymmetric, meaning that a large oocyte (containing most of the cytoplasm) and minor polar body are produced as a result of meiosis I, and again following meiosis II. Since only oocytes will go on to form embryos if fertilized, this unequal...

Changes in Skin Color: Clinical Perspectives

4.1K
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...

Pigmentation01:19

Pigmentation

5.0K
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...

Photoreceptors and Visual Pathways01:22

Photoreceptors and Visual Pathways

11.0K
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,...

Necrosis01:16

Necrosis

7.2K
Necrosis is considered as an “accidental” or unexpected form of cell death that ends in cell lysis. The first noticeable mention of “necrosis” was in 1859 when Rudolf Virchow used this term to describe advanced tissue breakdown in his compilation titled “Cell Pathology”.
Morphological Manifestations of Necrosis
Necrotic cells show different types of morphological appearance depending on the type of tissue and infection. In coagulative necrosis, cells become...

Summary
This summary is machine-generated.

Exogenous ochronosis (EO) is a rare skin condition causing blue-black pigmentation, often from skin-lightening products. Treatment options for this disfiguring disorder are currently limited and disappointing.

Area of Science:

  • Dermatology
  • Cutaneous Medicine

Background:

  • Exogenous ochronosis (EO) presents as blue-black skin pigmentation.
  • It is a complication of long-term hydroquinone use, but also phenol, resorcinol, or quinine.
  • EO is clinically and histologically similar to endogenous ochronosis (alkaptonuria).

Purpose of the Study:

  • To summarize the characteristics and challenges of exogenous ochronosis.
  • To highlight diagnostic methods and treatment difficulties.

Main Methods:

  • Review of clinical and histological features of exogenous ochronosis.
  • Discussion of diagnostic tools like dermoscopy and confocal microscopy.
  • Assessment of current treatment limitations.

Main Results:

  • Exogenous ochronosis is characterized by specific pigmentation patterns.
  • Non-invasive diagnostic tools aid in identifying the condition.
  • Effective treatment strategies for exogenous ochronosis remain elusive.

Conclusions:

  • Exogenous ochronosis is a challenging cosmetic disorder with limited therapeutic options.
  • Further research is needed to develop effective treatments for exogenous ochronosis.
