Skin Cancer01:30

Skin Cancer

6.3K
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...

Veins of Head and Neck01:19

Veins of Head and Neck

6.2K
The blood drainage from the head and neck is primarily managed by three pairs of veins: the external jugular, internal jugular, and vertebral veins. The external jugular veins drain superficial scalp and face structures, passing over the sternocleidomastoid muscles to empty into the subclavian veins.
On the other hand, the vertebral veins, unlike their arterial counterparts, are not primarily responsible for brain drainage. Instead, they drain the cervical vertebrae, spinal cord, and some small...

Papillary Dermis01:11

Papillary Dermis

6.3K
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...

Nose and Nasal Cavity01:24

Nose and Nasal Cavity

13.2K
The nose is composed of an observable exterior segment (external nose) and an internal segment within the skull known as the nasal cavity (internal nose). The external nose, visible on the face, consists of a framework of bone and hyaline cartilage enveloped in skin and muscle and lined with a mucous membrane. This structure is supported by the frontal bone, nasal bones, and maxillary bone and is supplemented by a cartilaginous framework comprising the septal nasal cartilage, lateral nasal...

The Retinoblastoma Gene01:20

The Retinoblastoma Gene

4.8K
Tumor suppressor genes are normal genes that can slow down cell division, repair DNA mistakes, or program the cells for apoptosis in case of irreparable damage. Hence, they play an essential role in preventing the proliferation of damaged cells.
The first-ever tumor suppressor gene called Rb was identified in retinoblastoma - a rare eye tumor in children. In inherited forms of the disease, a child inherits one defective copy of the Rb gene, which predisposes them to retinoblastoma. However,...

Prosopagnosia01:24

Prosopagnosia

984
Prosopagnosia, also known as face blindness, is the inability to recognize faces. In severe cases, individuals with prosopagnosia may not recognize close family members, including parents and spouses, by their faces. For instance, someone with prosopagnosia might walk past their child in a crowd, only realizing their mistake upon noticing their child's distinctive backpack or favorite jacket. Prosopagnosia specifically impairs facial recognition, while the recognition of other objects or...

Area of Science:

  • Dermatology
  • Ophthalmology
  • Genetics

Background:

  • Nevus of Ota is a congenital melanocytosis affecting the first and second branches of the trigeminal nerve.
  • It is characterized by unilateral, patchy, blue-grey pigmentation of the skin and conjunctiva.
  • The condition is more prevalent in Asian populations.

Observation:

  • A 22-year-old Caucasian female presented with a progressively spreading pale-blue nevus.
  • The nevus involved the forehead and bulbar conjunctiva since age 15, later extending to the contralateral forehead, cheek, and sclera.
  • No neurological deficits, hearing impairment, or vision loss were noted.

Findings:

  • The patient's presentation is atypical due to her Caucasian ethnicity.
  • Bilateral involvement of Nevus of Ota is uncommon.
  • The case underscores the importance of recognizing ethnic variations in dermatological conditions.

Implications:

  • Early diagnosis and management of Nevus of Ota are crucial to prevent potential complications.
  • Understanding the rarity in Caucasian individuals aids in differential diagnosis.
  • This case prompts further research into the genetic and environmental factors influencing Nevus of Ota.
