Summary
Cutaneous collagenous vasculopathy, a rare microangiopathy, typically presents as telangiectasia. This study introduces a new clinical variant,
Area of Science:
- Dermatology
- Pathology
- Vascular Biology
Background:
- Cutaneous collagenous vasculopathy (CCV) is a rare condition characterized by superficial dermal microangiopathy.
- CCV lesions often manifest clinically as telangiectasias.
Observation:
- A patient presented with histopathologic features of CCV and scattered erythematous papules on the trunk.
- Dermatoscopic examination revealed unique findings in the observed papules.
Findings:
- The study identified a novel clinical presentation of CCV.
- This presentation includes erythematous papules and distinct dermatoscopic features.
Implications:
- This expands the known clinical spectrum of cutaneous collagenous vasculopathy.
- The term 'cutaneous papular collagenous vasculopathy' is proposed for this new manifestation.
- Further research may clarify the pathogenesis and diagnostic criteria for this variant.

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...

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.

01:15Reticular Dermis
4.5K
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.

Underlying the papillary layer is the much thicker reticular layer, composed of dense, irregular connective...

5.7K
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.

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...

01:05Type IV Collagen of Basal Lamina
3.0K
Type IV collagen is a 400 nm long, network-forming collagen that acts as a barrier between the epithelial and endothelial cells. Type IV collagen forms the backbone of the basement membrane by scaffolding with laminin, entactin, proteoglycans, and fibronectin. Apart from rendering structural support to the basement membrane, it also helps entail signaling potentials necessary for both pathological and physiological functions.
