Summary
Cerebriform nevus sebaceus is a rare variant of epidermal nevi. This case report details an unusually widespread distribution of this condition across the head, face, and trunk.
Area of Science:
- Dermatology
- Genetics
- Pathology
Background:
- Nevus sebaceus is a congenital skin condition characterized by abnormal development of sebaceous glands.
- It typically presents as a yellowish plaque, commonly on the head and neck.
- Genetic mosaicism is understood to underlie nevus formation and influence lesion morphology.
Observation:
- A rare morphological variant, cerebriform nevus sebaceus, was first described in 1998.
- This report presents a patient with cerebriform nevus sebaceus exhibiting an extensive distribution.
- The lesions covered the head, face, and trunk of the affected individual.
Findings:
- The patient's cerebriform nevus sebaceus displayed an unusually widespread distribution.
- Despite the extensive cutaneous involvement, no other organ systems were affected.
- This presentation expands the known spectrum of nevus sebaceus variants.
Implications:
- This case highlights the variable presentation and distribution of cerebriform nevus sebaceus.
- Understanding the genetic basis of mosaicism is crucial for predicting nevus patterns.
- Further research into rare epidermal nevi can improve diagnostic and management strategies.

01:30Skin Cancer
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.

01:21Accessory Structures of the Skin: Sebaceous Glands
A sebaceous gland is a type of oil gland found almost all over the skin ( except palms and soles) and helps lubricate and waterproof the skin and hair. Most sebaceous glands are associated with hair follicles. They generate and excrete sebum, a mixture of lipids, onto the skin surface, thereby naturally lubricating the dry and dead layer of keratinized cells of the stratum corneum, keeping it pliable.
These glands that produce the oils on the skin and hair are holocrine glands. The mature...

01:26Cushing Syndrome I: Introduction
Cushing syndrome refers to the collection of clinical manifestations that arise when tissues are exposed to excessive amounts of cortisol or cortisol-like medications over an extended period. Cortisol, a glucocorticoid produced by the adrenal cortex, regulates metabolism, immune responses, and the body’s adaptation to stress. When its concentration remains chronically elevated, these physiological pathways become dysregulated, resulting in the characteristic features of the syndrome.Exogenous...
01:22Cerebral Edema ll: Pathophysiology
Vasogenic edema is a major form of cerebral edema characterized by abnormal accumulation of fluid in the brain’s extracellular space due to disruption of the blood–brain barrier (BBB). The BBB is a specialized structure composed of endothelial cells connected by tight junctions, supported by astrocytic endfeet and a basement membrane. Under normal conditions, it tightly regulates the movement of ions, proteins, and solutes between the bloodstream and brain parenchyma. When this barrier loses...
01:19Cushing Syndrome II: Pathophysiology
Cortisol production is normally governed by the hypothalamic–pituitary–adrenal (HPA) axis, which maintains hormonal balance through tightly regulated feedback mechanisms. Disruption of this regulatory system is central to the development of Cushing syndrome, whether the excess cortisol originates from external medications or internal pathology. Persistent cortisol elevation alters metabolism, immune function, and endocrine signaling, producing the characteristic clinical features of the...
01:24Prosopagnosia
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...
