Skin Cancer

5.2K
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

28
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...

Reticular Dermis01:15

Reticular Dermis

4.6K
The papillary and reticular dermis are the two layers of the dermis. They are made of connective tissue with fibers of collagen extending from one to the other, making the border between the two somewhat indistinct. The dermal papillae extending into the epidermis belong to the papillary layer, whereas the dense collagen fiber bundles below belong to the reticular layer.
Reticular Layer
Underlying the papillary layer is the much thicker reticular layer, composed of dense, irregular connective...

Skin Diseases and Disorders

5.4K
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...

Papillary Dermis01:11

Papillary Dermis

5.8K
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...

Endocarditis II: Clinical Features of Infective Endocarditis

929
Endocarditis can present various clinical features depending on the causative organism and the patient's underlying health conditions. Initially, the clinical features of infective endocarditis develop gradually, presenting with nonspecific symptoms that can be easily mistaken for other illnesses.General SymptomsEarly symptoms of infective endocarditis are fever, chills, weakness, malaise, fatigue, and weight loss. These symptoms reflect the systemic nature of the infection and the body's...

Area of Science:

  • Dermatopathology
  • Histopathology
  • Cutaneous Oncology

Background:

  • Verruciform xanthoma is a rare, benign oral and cutaneous condition.
  • It typically presents as a solitary papule or plaque.
  • Differential diagnosis includes various benign and malignant epithelial and connective tissue neoplasms.

Observation:

  • A 50-year-old male presented with a several-month history of a scrotal polypoid papule.
  • Physical examination revealed a solitary, exophytic lesion on the scrotum.

Findings:

  • Histopathological examination of the biopsy specimen showed a dense accumulation of macrophages with foamy cytoplasm.
  • These findings are characteristic of verruciform xanthoma.
  • No significant atypia or malignancy was identified.

Implications:

  • This case highlights the importance of considering verruciform xanthoma in the differential diagnosis of scrotal papules.
  • Accurate histopathological diagnosis is crucial for appropriate management and patient reassurance.
  • Further research into the etiology and specific treatment protocols for cutaneous verruciform xanthoma is warranted.
