Skin Cancer

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.
Basal Cell Carcinoma (BCC): BCC is the most common type of skin cancer, accounting for about 80% of cases. It typically develops in...

Rous Sarcoma Virus (RSV) and Cancer

Rous 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.
RSV is a retrovirus that contains two copies of a plus-strand RNA genome. Its genome consists of four main open...

Skin Diseases and Disorders

Skin 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.
Gram-positive Staphylococcus spp. and Streptococcus spp. are responsible for many of the most common skin infections. However, many...

Area of Science:

Dermatopathology
Oncology
Soft Tissue Sarcoma Research

Background:

Primary cutaneous leiomyosarcoma (PCL) is a rare malignant neoplasm.
It typically affects middle-aged to elderly males.
Distinguishing PCL from other spindle cell tumors is diagnostically challenging.

Observation:

This report details a case of PCL in a 70-year-old male.
The tumor arose on the right leg.
Morphological assessment alone is insufficient for diagnosis.

Findings:

Immunohistochemical markers are essential for accurate PCL diagnosis.
A panel of markers aids in differentiating PCL from other spindle cell neoplasms.
Definitive diagnosis relies on integrating morphology and immunohistochemistry.

Implications:

Improved diagnostic strategies for PCL are crucial.
Accurate diagnosis impacts patient treatment and prognosis.
Further research into PCL pathogenesis and management is warranted.
