Summary
This case report highlights chronic hypertrophic lichen planus (HLP) as a potential precursor for cutaneous squamous cell carcinoma (SCC). Early detection through regular screening is crucial for better patient outcomes in SCC development.
Area of Science:
- Dermatology
- Oncology
Background:
- Squamous cell carcinoma (SCC) is the second most common skin malignancy.
- Cutaneous SCC can arise in various clinical settings.
Observation:
- A case of an elderly male with bilateral lower limb lesions is presented.
- Right shin: non-healing ulceroproliferative growth.
- Left shin: SCC arising in a background of chronic hypertrophic lichen planus (HLP).
Findings:
- This case demonstrates SCC development in the context of HLP.
- SCC on the right limb lacked evidence of HLP.
- Literature review indicates limited reported cases of HLP-associated SCC.
Implications:
- Chronic hypertrophic lichen planus should be recognized as a potential precursor lesion for cutaneous squamous cell carcinoma.
- Regular screening is vital for early SCC detection and timely intervention.
- This case contributes to understanding risk factors for cutaneous SCC.

01:30Skin Cancer
4.1K
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.

01:21Barrett Esophagus-I: Introduction
90
Barrett's esophagus is a medical condition where the esophageal mucosa is significantly damaged by stomach acid or other digestive fluids, often due to long-term exposure associated with gastroesophageal reflux disease (GERD). In GERD, a weakened or abnormally relaxed lower esophageal sphincter allows stomach acid to flow persistently into the esophagus.
This constant acid exposure transforms the esophagus's pink mucosal lining (stratified squamous epithelium) into a type of lining more...

01:06Multipotency and Niche of Bulge Stem Cell
3.6K
A hair follicle or HF is a small part of the skin that produces the hair shaft. Paul Gerson Unna was the first to observe a bulge in the human hair follicle's outer root sheath (ORS). The bulge is present between the sebaceous gland and the arrector pili muscle and is the niche for hair follicle stem cells (HFSCs). The bulge is also a niche for melanocyte stem cells, and their loss results in graying of hair. The HFSCs express Sox9 and Lhx2, which help them maintain stemness and prevent...

02:23Abnormal Proliferation
4.5K
Under normal conditions, most adult cells remain in a non-proliferative state unless stimulated by internal or external factors to replace lost cells. Abnormal cell proliferation is a condition in which the cell's growth exceeds and is uncoordinated with normal cells. In such situations, cell division persists in the same excessive manner even after cessation of the stimuli, leading to persistent tumors. The tumor arises from the damaged cells that replicate to pass the damage to the...
