Changes in Skin Color: Clinical Perspectives

Changes in Skin Color: Clinical Perspectives

The first thing a clinician sees is the skin, so the examination of the skin should be part of any thorough physical examination. Most skin disorders are relatively benign, but a few, including melanomas, can be fatal if untreated. A couple of the more noticeable disorders, albinism and vitiligo, affect the appearance of the skin and its accessory organs.
Albinism
Albinism is a genetic disorder that affects (completely or partially) the coloring of skin, hair, and eyes. The defect is primarily...

mTOR Signaling and Cancer Progression

mTOR Signaling and Cancer Progression

The mammalian target of rapamycin or mTOR protein was discovered in 1994 due to its direct interaction with rapamycin. The protein gets its name from a yeast homolog called TOR. The mTOR protein complex in mammalian cells plays a major role in balancing anabolic processes such as the synthesis of proteins, lipids, and nucleotides and catabolic processes, such as autophagy in response to environmental cues, such as availability of nutrients and growth factors.
The mTOR pathway or the...

Tumor Progression

Tumor Progression

Tumor progression is a phenomenon where the pre-formed tumor acquires successive mutations to become clinically more aggressive and malignant. In the 1950s, Foulds first described the stepwise progression of cancer cells through successive stages.
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...

Area of Science:

Dermatology
Rheumatology
Immunology

Background:

Morphea is a rare autoimmune condition causing skin inflammation and sclerosis.
It leads to permanent damage like tissue loss, atrophy, and joint contractures if untreated.
Early identification of active morphea is crucial to prevent severe sequelae.

Purpose of the Study:

To review current understanding of morphea pathogenesis.
To highlight the need for validated outcome measures for activity and damage.
To emphasize the lack of targeted therapies and the need for further research.

Main Methods:

Review of recent investigative work on morphea.
Analysis of studies focusing on clinical, biomarker, imaging, and histologic outcomes.
Examination of research on immune and fibrotic pathways in morphea pathogenesis.

Main Results:

Dysregulated immune and fibrotic pathways, particularly interferon (IFN) gamma related pathways, are implicated in morphea.
Active lesions show inflammatory signatures (CXCR3 ligands) and fibrotic signatures (fibroblast activation).
CXCL9 and 10 are associated with increased disease activity.

Conclusions:

Further research is essential to elucidate morphea pathogenesis and identify novel therapeutic targets.
Validated outcome measures are needed for clinical and research settings.
Development of targeted therapies is hindered by a lack of understanding of disease mechanisms.
