Skin Cancer01:30

Skin Cancer

4.8K
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...

Abnormal Proliferation02:23

Abnormal Proliferation

4.7K
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...

Tumor Progression02:07

Tumor Progression

6.5K
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...

Assessment of the Rectum and Anus01:25

Assessment of the Rectum and Anus

471
Evaluating the rectum and anus plays a crucial role in conducting a thorough physical examination of the gastrointestinal system. Although it may be uncomfortable and often embarrassing for the patient, it holds immense diagnostic value, particularly in detecting gastrointestinal diseases and abnormalities. This guide will explain how to perform this assessment using inspection and palpation methods.
Rectal Inspection
Begin by inspecting the perianal and anal areas for color, texture, rashes,...

Tumor Immunotherapy01:27

Tumor Immunotherapy

708
Immunotherapy is a treatment that boosts or manipulates the immune system to fight diseases, including cancer. For instance, by stimulating an immune response through vaccinations against viruses that cause cancers, like hepatitis B virus and human papillomavirus, these diseases can be prevented. Nonetheless, some cancer cells can avoid the immune system due to their rapid mutation and division. The immune response to many cancers involves three phases: elimination, equilibrium, and escape.

Classification of Epithelial Tissues: Glandular Epithelium01:20

Classification of Epithelial Tissues: Glandular Epithelium

10.1K
The glandular epithelium is made of one or more epithelial cells modified to synthesize and secrete chemical substances. Glandular epithelia can be classified based on cell number. Unicellular glands have individual secretory cells scattered across the epithelial monolayer. In contrast, multicellular glands consist of a hollow tubular duct attached to the cluster of secretory cells located in the deep pockets.
Multicellular glands are formed during early development when epithelial budding...

Area of Science:

  • Radiology
  • Pathology
  • Oncology

Background:

  • Benign and malignant soft tissue tumors often present with overlapping imaging features.
  • Misinterpretation can lead to misdiagnosis and unnecessary patient anxiety.
  • Accurate differentiation is essential for appropriate patient management.

Purpose of the Study:

  • To discuss the imaging and clinical features of 6 common benign soft tissue tumor mimics.
  • To highlight lesions that are frequently misdiagnosed as malignancy.
  • To improve diagnostic accuracy and reduce patient anxiety.

Main Methods:

  • Review of imaging and clinical features of 6 specific soft tissue lesions.
  • Comparison of features to differentiate benign mimics from malignant tumors.
  • Discussion of common pitfalls in diagnosis.

Main Results:

  • Myositis ossificans, acute traumatic hematoma, geyser lesion, tumoral calcinosis, gout, and myonecrosis are common mimics.
  • These lesions can present as soft tissue masses with features mimicking malignancy.
  • Familiarity with their characteristic presentations is key to correct diagnosis.

Conclusions:

  • Recognizing these 6 benign soft tissue tumor mimics is vital for radiologists.
  • Accurate identification can spare patients from invasive work-ups and reduce anxiety.
  • Improved understanding of these mimics enhances diagnostic confidence and patient care.
