Summary
Cutaneous epithelioid angiomatous nodules are rare benign vascular growths. Two new cases highlight their typical features, emphasizing a high mitotic index in these epithelioid cell proliferations.
Area of Science:
- Dermatopathology
- Vascular Biology
- Oncology
Background:
- Cutaneous epithelioid angiomatous nodule is a recently described benign vascular proliferation.
- It typically presents as a solitary, rapidly growing, small reddish papulous or nodular lesion on adult skin.
Observation:
- Histopathology shows epithelioid cell proliferation with solid, well-delimited, unilobular growth in the superficial dermis.
- Lesions contain well-defined vessels, inflammatory infiltration, and epithelioid cells with abundant cytoplasm and prominent nucleoli.
- Cellular morphology is uniform without atypia, though mitoses can be present.
Findings:
- Two new cases of cutaneous epithelioid angiomatous nodules are presented.
- Both cases exhibited typical features alongside a notably high mitotic index.
- The cases occurred in a pregnant woman and a young man.
Implications:
- This study contributes to understanding the spectrum of cutaneous vascular proliferations.
- It highlights the importance of considering a high mitotic index in the differential diagnosis.
- Further research may clarify the behavior and potential management of this uncommon entity.

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.

Abnormal Proliferation
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 daughter...

Papillary 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...

Multipotency and Niche of Bulge Stem Cell
A hair follicle or HF is a small part of the skin that produces the hair shaft. Paul Gerson Unna was the first to observe a bulge in the human hair follicle's outer root sheath (ORS). The bulge is present between the sebaceous gland and the arrector pili muscle and is the niche for hair follicle stem cells (HFSCs). The bulge is also a niche for melanocyte stem cells, and their loss results in graying of hair. The HFSCs express Sox9 and Lhx2, which help them maintain stemness and prevent...
Secondary Lymphoid Organs
Secondary organs, including lymph nodes, the spleen, and mucosa-associated lymphoid tissue (MALT), work harmoniously to protect us from disease and infection.
The spleen is a vital organ in the lymphatic system, nestled in the upper left side of the abdomen. It is composed of two primary regions: the red pulp and the white pulp, each having distinct functions. The red pulp performs a significant role in blood filtration. It efficiently purges the blood of old or damaged red blood cells and...
