Cranial and Spinal Meninges01:19

Cranial and Spinal Meninges

The cranial and spinal meninges are complex protective structures surrounding the central nervous system (CNS), consisting of the brain and spinal cord. These meninges consist of the dura mater, the arachnoid mater, and the pia mater. They protect the CNS, provide structural support, and aid in circulating cerebrospinal fluid (CSF).
Cranial Meninges
These meningeal layers cover the cranium. The dura mater is the outermost layer of cranial meninges. It is a thick and durable membrane of dense...
Skin Cancer01:30

Skin 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.
Basal Cell Carcinoma (BCC): BCC is the most common type of skin cancer, accounting for about 80% of cases. It typically develops in...
Bacterial Meningitis I: Introduction01:22

Bacterial Meningitis I: Introduction

Bacterial meningitis is a severe, life-threatening inflammation of the meninges, particularly the pia mater and arachnoid mater, affecting the subarachnoid space, ventricles, and cerebrospinal fluid (CSF). If untreated, it can lead to significant neurological complications or death.Causative AgentsCommon pathogens vary with age and immune status. In adults, major organisms include Streptococcus pneumoniae, Neisseria meningitidis, and Haemophilus influenzae. Streptococcus agalactiae (group B...
Viral Meningitis01:18

Viral Meningitis

Viral meningitis is the most common form of meningitis and is often referred to as aseptic meningitis to indicate the absence of bacterial involvement. It is generally milder than bacterial meningitis, with symptoms including fever, headache, stiff neck, drowsiness, nausea, photophobia, and vomiting. Rarely, more severe manifestations or death may occur. Common causative agents include enteroviruses, particularly coxsackie A and B viruses and echoviruses, all members of the Enterovirus genus...
Skin Diseases and Disorders01:23

Skin Diseases and Disorders

Skin is the first line of defense and encounters a variety of microbes. Some pathogenic strains are often the cause of a broad range of infections of the skin and other body systems. These conditions can affect people of all ages and may have different causes, including genetic factors, infections, autoimmune reactions, environmental factors, and lifestyle choices.
Gram-positive Staphylococcus spp. and Streptococcus spp. are responsible for many of the most common skin infections. However, many...
Bacterial Meningitis II: Pathophysiology01:26

Bacterial Meningitis II: Pathophysiology

Bacterial meningitis typically begins when pathogens such as Neisseria meningitidis and Streptococcus pneumoniae colonize the nasopharynx and invade the bloodstream. This process is facilitated by bacterial virulence factors, such as polysaccharide capsules, which resist phagocytosis and complement-mediated killing. Less commonly, bacteria reach the central nervous system via contiguous spread from infections like otitis media or sinusitis, through congenital or acquired dural defects, or...

Summary

Cutaneous meningiomas are rare scalp tumors with congenital or acquired origins. Diagnosis relies on characteristic histologic and cytologic findings, distinguishing them from other conditions.

Area of Science:

  • Dermatopathology
  • Oncology
  • Surgical Pathology

Background:

  • Cutaneous meningioma is a rare neoplasm predominantly affecting the scalp.
  • It presents in both congenital and acquired forms, with congenital lesions sometimes appearing years after birth.
  • These tumors present a broad clinical differential diagnosis.

Purpose of the Study:

  • To review the histologic, cytologic, and electron microscopic findings of cutaneous meningioma.
  • To elucidate how these findings aid in differentiating cutaneous meningioma from other conditions.
  • To highlight the importance of recognizing this entity for accurate diagnosis.

Main Methods:

  • Review of literature on cutaneous meningioma.
  • Analysis of histologic, cytologic, and electron microscopic features.

  • Comparison with differential diagnostic entities.

    • Main Results:

    • Cutaneous meningiomas exhibit characteristic histologic and cytologic findings crucial for diagnosis.
    • Ultrastructural and cytologic features resemble intracranial meningiomas.
    • Histologic findings show a range of differences compared to intracranial counterparts.

    Conclusions:

    • Accurate diagnosis of cutaneous meningioma depends on recognizing its specific histologic and cytologic features.
    • Awareness of this rare entity is essential to avoid misdiagnosis.
    • Histologic variations necessitate careful evaluation to distinguish from other scalp lesions.
