Summary
This is the first reported case of cutaneous leiomyosarcoma (CLM) developing in a smallpox scar. Awareness of potential malignant transformation in old scars is crucial for early detection.
Area of Science:
- Oncology
- Dermatology
- Pathology
Background:
- Cutaneous leiomyosarcoma (CLM) is a rare smooth muscle tumor, representing 2-3% of superficial soft tissue sarcomas.
- Malignancies can develop in scar tissue, but CLM in a smallpox scar is unprecedented.
Observation:
- A 66-year-old man presented with a slow-growing lump in a smallpox scar on his left shoulder.
- Histological examination confirmed a well-differentiated primary cutaneous leiomyosarcoma.
- CT scan revealed no metastases; the lesion was surgically excised completely.
Findings:
- Histopathology confirmed radical excision of the cutaneous leiomyosarcoma.
- The patient showed no signs of recurrence after 13 months of follow-up.
- This case represents the first documented instance of CLM arising within a smallpox scar.
Implications:
- Clinicians should consider malignant transformation in patients presenting with atypical changes or symptoms in old smallpox scars.
- While difficult to establish strict follow-up protocols due to the long latency, vigilance is recommended.
- This case highlights the importance of monitoring long-term changes in scar tissue for potential oncological development.

01:30Skin 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.

01:19Clinical Applications of Epidermal Stem Cells
Epidermal stem cells (EpiSCs) are mainly located at the basal layer of the epidermis. These cells repair minor injuries of the skin and replace dead skin cells. However, EpiSCs’ cannot heal severe wounds such as major burns or those from diabetes or hereditary disorders. In such cases, culturing the epidermal stem cells from the patient is possible and has yielded successful treatment options, such as laboratory-grown skin grafts. These grafts are synthesized using a patient’s own EpiSCs...
01:23Skin Diseases and Disorders
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.

01:11Papillary 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...

01:03Rous Sarcoma Virus (RSV) and Cancer
Rous Sarcoma virus or RSV was discovered by F. Peyton Rous in the year 1911 as a filterable transmissible agent that could cause tumors in chickens. He won a Nobel Prize for this discovery in 1966. His experiments clearly demonstrated that some cancers could be caused by infectious agents and led to the discovery of many more cancer-causing viruses in animals as well as humans.
