Skin Cancer01:30

Skin Cancer

5.2K
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...

Papillary Dermis01:11

Papillary Dermis

5.8K
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...

Diabetic Foot Ulcer01:31

Diabetic Foot Ulcer

33
Definition A diabetic foot ulcer (DFU) is a chronic, non-healing wound that develops in individuals with diabetes. It typically occurs on pressure-bearing areas such as the heel, metatarsal heads, or hallux, and carries a high risk of infection and amputation.Pathophysiology • The development of DFUs can be explained by four interconnected mechanisms: neuropathy, ischemia, infection, and impaired wound healing. • Neuropathy is the most common factor. Sensory...

Reticular Dermis01:15

Reticular Dermis

4.6K
The papillary and reticular dermis are the two layers of the dermis. They are made of connective tissue with fibers of collagen extending from one to the other, making the border between the two somewhat indistinct. The dermal papillae extending into the epidermis belong to the papillary layer, whereas the dense collagen fiber bundles below belong to the reticular layer.
Reticular Layer
Underlying the papillary layer is the much thicker reticular layer, composed of dense, irregular connective...

Inflammatory Bowel Disease II: Ulcerative Colitis01:20

Inflammatory Bowel Disease II: Ulcerative Colitis

34
Ulcerative colitis is a chronic inflammatory disorder of the colon characterized by continuous mucosal inflammation that typically begins in the rectum and extends proximally in a uniform pattern. Its pathogenesis involves a complex interplay of genetic predisposition, immune dysregulation, and environmental influences. These factors converge to impair the colon’s epithelial defenses and promote an exaggerated inflammatory response against luminal contents.Breakdown of the Mucosal...

Skin Diseases and Disorders

5.4K
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:

  • Dermatology
  • Oncology
  • Pathology

Background:

  • Dermatofibroma is a common benign skin tumor, typically presenting as hard papules/nodules.
  • Rare erosions/ulcerations can complicate dermatofibroma diagnosis.
  • Dermatofibrosarcoma protuberans (DFSP) is a malignant tumor with similar clinical and histopathological features, posing diagnostic challenges.

Purpose of the Study:

  • To report an exceptionally large ulcerative dermatofibroma on the head and neck.
  • To discuss the diagnostic difficulties presented by this case, particularly its resemblance to DFSP.

Main Methods:

  • Case presentation of a giant ulcerative dermatofibroma.
  • Histopathological examination to confirm the diagnosis.
  • Comparison with clinical and histopathological features of DFSP and other skin cancers.

Main Results:

  • A giant ulcerative dermatofibroma, the largest reported on the head and neck, was identified.
  • The lesion exhibited features mimicking dermatofibrosarcoma protuberans, basal cell carcinoma, epidermoid carcinoma, and sarcomas.
  • Histopathology confirmed the benign nature of the tumor despite its aggressive appearance.

Conclusions:

  • Giant ulcerative dermatofibromas, though rare, can present significant diagnostic challenges due to their resemblance to malignant neoplasms.
  • Accurate histopathological evaluation is crucial for differentiating benign dermatofibroma from malignant tumors like DFSP, especially in unusual presentations.
  • This case underscores the importance of considering benign entities even when faced with lesions that appear clinically aggressive.
