Insights

Infantile myofibromatosis (IMF) is a common childhood fibromatosis. This case highlights a newborn with a scalp nodule diagnosed as IMF, emphasizing its varied presentations and prognosis based on type.

Area of Science:

  • Pediatric Pathology
  • Dermatology
  • Surgical Oncology

Background:

  • Infantile myofibromatosis (IMF) is the most prevalent fibromatosis in childhood.
  • It represents a benign proliferation of fibroblasts and myofibroblasts.
  • IMF can manifest in solitary, multicentric, or generalized forms with visceral involvement.

Observation:

  • A newborn presented with a purple cutaneous nodule on the scalp at birth.
  • Surgical excision was performed at 16 months of age.
  • Histological examination confirmed infantile myofibromatosis.

Findings:

  • Histological diagnosis of IMF relies on identifying a fascicular myofibroblastic pattern peripherally and a hemangiopericytoma-like pattern centrally.
  • Both components typically express alpha-smooth muscle actin.
  • While solitary IMF has a good prognosis, generalized forms with visceral involvement are often fatal.

Implications:

  • This case underscores the importance of accurate histological diagnosis for appropriate management of infantile myofibromatosis.
  • Understanding the different forms of IMF is crucial for predicting patient outcomes.
  • Early recognition and surgical intervention may be beneficial for localized lesions.

Papillary Dermis01:11

Papillary Dermis

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 and...
Fibril-associated Collagen01:11

Fibril-associated Collagen

Fibril-associated collagens are a type of collagens present in the extracellular matrix with interrupted triple helices or FACIT (Fibril-associated collagens interrupted triple-helices). FACIT help connect and attach the collagen fibrils with each other as well as with other proteins of the extracellular matrix.
For example, the type II collagen fibrils in cartilage have covalently bound type IX fibril-associated collagens at regular intervals. Other types of fibril-associated collagens are...
Classification of Skeletal Muscle Fibers01:48

Classification of Skeletal Muscle Fibers

Skeletal muscles continuously produce ATP to provide the energy that enables muscle contractions. Skeletal muscle fibers can be categorized into three types based on differences in their contraction speed and how they produce ATP, as well as physical differences related to these factors. Most human muscles contain all three muscle fiber types, albeit in varying proportions.

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...

Cirrhosis I: Introduction

Cirrhosis is a chronic, irreversible liver disease characterized by the widespread replacement of healthy liver tissue with fibrotic scar tissue and the formation of regenerative nodules.Etiology of cirrhosisCirrhosis results from sustained liver injury that triggers progressive fibrosis and structural remodeling. The underlying causes are diverse, encompassing common and less frequent clinical conditions. Regardless of the origin, all causes lead to chronic inflammation, hepatocyte loss, and...
