Summary
A rare combined trichoepithelioma and cellular blue nevus, a biphasic lesion, can clinically resemble melanoma. This study details a fourth case, contributing to understanding these rare tumors.
Area of Science:
- Dermatopathology
- Oncology
- Dermatology
Background:
- Biphasic lesions with melanocytic and epithelial components are recognized.
- Combined trichoepithelioma and cellular blue nevus is a rare entity.
- This rare tumor can present a clinical challenge due to its resemblance to melanoma.
Purpose of the Study:
- To report the fourth case of combined trichoepithelioma and cellular blue nevus.
- To review existing literature on this rare tumor.
- To discuss the pathogenesis of basomelanocytic tumors.
Main Methods:
- Case presentation of a rare tumor.
- Literature review of combined trichoepithelioma and cellular blue nevus.
- Discussion of recent findings on malignant basomelanocytic tumors.
Main Results:
- The authors present the fourth documented case of combined trichoepithelioma and cellular blue nevus.
- Literature review confirms the rarity and clinical mimicry of melanoma.
- Recent studies on malignant basomelanocytic tumors offer insights into pathogenesis.
Conclusions:
- Combined trichoepithelioma and cellular blue nevus is an exceptionally rare biphasic tumor.
- Accurate diagnosis is crucial due to clinical resemblance to melanoma.
- Further research into the pathogenesis of these mixed-lineage tumors is warranted.

01:24Cells of the Epidermis
The epidermis is made of four or five layers of epithelial cells, depending on its location in the body. From deep to superficial, these layers are the stratum basale, stratum spinosum, stratum granulosum, stratum lucidum, and stratum corneum.
The cells in all these layers except the stratum basale are called keratinocytes, a type of cell that manufactures and stores the protein keratin. The keratinocytes in the stratum corneum are dead and regularly slough away, being replaced by cells from...

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...

01:29Classification of Epithelial Tissues: Stratified Epithelium
Stratified epithelium consists of several stacked layers of cells. They provide the durability to withstand constant physical and chemical attacks. Stratified epithelium is named after the shape of the most apical layer of cells. Stratified squamous epithelium is the most common type found in the human body. In this tissue, the apical cells are squamous, whereas the basal layer contains either columnar or cuboidal cells. The basal cells divide to form new daughter cells, which gradually become...
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.
Basal Cell Carcinoma (BCC): BCC is the most common type of skin cancer, accounting for about 80% of cases. It typically develops in...

01:30Classification of Epithelial Tissues: Simple Epithelium
Simple epithelium consists of a single layer of cells that lines body cavities and blood vessels. The shape of the cells in the epithelium reflects the function of the tissue. Cells in simple squamous epithelium appear as thin scales with flat, elliptical nuclei that mirror the form of the cell.
Because of the thinness of the cells, simple squamous epithelium is present where the rapid passage of chemical compounds is observed. For example, the endothelium that lines the capillaries and vessels...

01:22Classification of Epithelial Tissues: Overview
Epithelial tissues are classified according to the shape of the cells and the number of cell layers formed. Cell shapes can be squamous (flattened and thin), cuboidal (square-like, as wide as it is tall), or columnar (rectangular, taller than it is wide). Additionally, the nucleus shape helps identify the type of epithelial cells. Squamous cells have flattened disc-shaped nuclei, cuboidal cells have spherical nuclei, and columnar cells have elongated nuclei.
