Summary
Hereditary reactive perforating collagenosis (RPC) is a rare condition. This case study highlights a familial diagnosis in siblings, suggesting a genetic basis for this rare perforating dermatosis.
Area of Science:
- Dermatology
- Genetics
- Pathology
Background:
- Reactive perforating collagenosis (RPC) is a rare perforating dermatosis.
- Two types exist: hereditary and acquired, with the latter associated with systemic diseases.
- Hereditary RPC typically manifests in early childhood.
Observation:
- A young man presented with crusted papular lesions on his hands since childhood.
- Histologic analysis revealed characteristic epidermal changes with extruded collagen.
- The patient's brother had similar lesions, supporting a hereditary diagnosis.
Findings:
- The case presented is consistent with hereditary reactive perforating collagenosis.
- The familial occurrence strongly suggests a genetic etiology.
- Superficial trauma is a suspected, though unproven, trigger for hereditary RPC.
Implications:
- This case reinforces the recognition of hereditary RPC as a distinct entity.
- Further research into the pathogenesis of hereditary RPC is warranted.
- Understanding the genetic basis may lead to targeted therapies for this rare dermatosis.

01:11Fibril-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...

01:05Type IV Collagen of Basal Lamina
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.

01:12Chronic Inflammation: Introduction
Chronic inflammation is a prolonged, dysregulated immune response that persists for weeks to years when the inciting stimulus is difficult to eradicate or when self‑antigens drive ongoing reactivity. Morphologically, it is defined by mononuclear cell infiltration, progressive tissue destruction, and concurrent attempts at healing via angiogenesis and fibrosis. Compared with acute inflammation, edema is less prominent while cellular infiltration predominates; triggers include persistent...
01:23Rheumatic Heart Disease I: Introduction
Rheumatic heart disease or RHD is a chronic condition that results from rheumatic fever, causing permanent damage to the heart valves.Etiology and Risk FactorsIt primarily arises from rheumatic fever, an inflammatory disease that can develop after untreated or inadequately treated group A streptococcal (GAS) pharyngitis. Streptococcus spreads through direct contact with oral or respiratory secretions. While the bacteria are the causative agents, factors like malnutrition, overcrowding, poor...
01:21Cytotoxic Edema: Pathophysiology
Cytotoxic edema is a form of cerebral edema characterized by intracellular swelling of neurons, astrocytes, and other glial cells. It develops when the mechanisms responsible for maintaining ionic gradients across the cell membrane become impaired. Under normal physiological conditions, the sodium–potassium ATPase actively transports sodium ions out of the cell and potassium ions into the cell, preserving osmotic balance and enabling electrical signaling. This pump requires a continuous supply...
01:24Healing 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...
