Summary
Two patients with progressive systemic sclerosis developed unusual keloid-like nodules. This suggests a potential keloidal response to early scleroderma inflammation in susceptible individuals or skin areas.
Area of Science:
- Dermatology
- Rheumatology
- Pathology
Background:
- Progressive systemic sclerosis (PSS) is an autoimmune disease characterized by skin thickening and fibrosis.
- Keloid formation is a complex fibroproliferative process of the skin.
- The co-occurrence of these conditions is exceptionally rare.
Observation:
- Two patients diagnosed with PSS presented with keloid-like nodules.
- These nodules developed within areas of thickened, sclerodermatous skin.
- The lesions mimicked the clinical and histological appearance of keloids.
Findings:
- The development of keloidal-like nodules in PSS is an extremely unusual event.
- This phenomenon is hypothesized to be a keloidal response to the early inflammatory phase of scleroderma.
- Predisposing factors may include genetic susceptibility to keloid formation or specific anatomical locations prone to keloids, such as the chest.
Implications:
- This finding expands the spectrum of cutaneous manifestations in progressive systemic sclerosis.
- It highlights the potential for aberrant wound healing responses in scleroderma.
- Further research is warranted to elucidate the precise mechanisms and identify at-risk patient populations.

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...

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.

Reticular Dermis
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...

Healing II: Complications
Complications during healing arise when tissue repair is altered by local or systemic factors. These changes involve abnormal collagen deposition, altered biomechanics, and reduced vascular supply, impairing restoration of normal structure and function.Loss of FunctionScar tissue differs significantly from the original tissue it replaces. In the skin, fibrosis lacks adnexal structures such as hair follicles, sebaceous glands, and sweat glands. Their absence reduces tactile sensitivity, impairs...
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...
Cirrhosis II: Pathophysiology
Cirrhosis is a progressive chronic liver injury caused by prolonged inflammation, excessive fibrotic remodeling, and impaired regeneration. Over time, repeated hepatic insults disrupt the liver’s architecture and function, leading to reduced blood flow, impaired bile drainage, and diminished metabolic capacity.Pathophysiology of cirrhosisCirrhosis arises from three main responses to chronic liver damage: inflammation, immune activation, and hepatocyte death. These processes lead to structural...
