Summary
CD34-positive dermal fibromas are benign skin tumors that can resemble a more aggressive cancer. Histopathology and cytogenetics are key to differentiating these conditions.
Area of Science:
- Dermatopathology
- Oncology
Background:
- CD34-positive dermal fibromas (PDFs) are cutaneous neoplasms characterized by superficial dermal spindle cell proliferation.
- These tumors are typically benign but share histopathological features with dermatofibrosarcoma protuberans (DFSP).
Observation:
- This report details a case of a CD34-positive dermal fibroma in a 38-year-old female.
- The lesion was located on the right antecubital fossa.
Findings:
- CD34-positive dermal fibromas exhibit overlapping features with DFSP, necessitating careful distinction.
- Cytogenetic studies are crucial for accurate diagnosis and differentiation.
Implications:
- Distinguishing CD34-PDFs from DFSP is essential for appropriate patient management and prognosis.
- Understanding the diagnostic challenges aids clinicians in evaluating similar cutaneous neoplasms.

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...

4.2K
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.

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...

01:15Reticular Dermis
2.6K
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...
