Insights

This study describes a novel benign skin tumor combining features of dermatofibroma, dermatomyofibroma, and lipoma. Histological analysis confirms it as a distinct entity with unique characteristics.

Area of Science:

  • Dermatopathology
  • Surgical Pathology
  • Oncology

Background:

  • Benign cutaneous mesenchymal lesions can present complex histological features.
  • Dermatofibromas, dermatomyofibromas, and lipomas are common skin tumors with distinct characteristics.
  • A need exists to classify unusual presentations of cutaneous lesions.

Observation:

  • A unique benign cutaneous mesenchymal lesion was identified.
  • The lesion exhibited histological features overlapping with dermatofibroma, dermatomyofibroma, and lipoma.
  • Immunohistochemical analysis was performed to characterize cellular components.

Findings:

  • The lesion demonstrated a unique histologic appearance.
  • It contained a mixture of mature adipose tissue, smooth muscle, and fibrous tissue.
  • Immunoreactant studies helped ascertain the nature of the constituent cells.

Implications:

  • The findings suggest this tumor represents a distinct clinicopathologic entity.
  • This entity is not precisely identical to any previously described lesion.
  • A descriptive name has been proposed for this newly identified tumor, aiding in its classification and understanding.

Mesenchymal Stem Cells

Mesenchymal stem cells (MSCs) are adult stem cells that can differentiate into most connective tissue cell types, except for hematopoietic cells, depending upon the source of MSCs. For example, bone-marrow-derived MSCs (BM-MSCs) can differentiate into osteocytes, hepatocytes, and pancreatic and neuronal cells. MSCs can be isolated from various sources such as bone marrow, placenta, adipose tissue, teeth, and Wharton’s jelly, a gelatinous substance in the umbilical cord. The ease of their access...
Renewal of Skin Epidermal Stem Cells01:12

Renewal of Skin Epidermal Stem Cells

The skin is divided into epidermis, dermis, and hypodermis, the skin's outermost, middle, and inner layers. The human epidermal layer regularly undergoes renewal, where old, dead cells are replaced by new cells. Epidermal stem cells or EpiSCs divide and differentiate to restore the lost cells. For the renewal process, some EpiSCs continuously self-renew. In contrast, few others differentiate into transit-amplifying cells, which later form prickle or spinous cells, followed by granular cells,...
Multipotency and Niche of Bulge Stem Cell01:06

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...
Clinical Applications of Epidermal Stem Cells01:19

Clinical Applications of Epidermal Stem Cells

Epidermal stem cells (EpiSCs) are mainly located at the basal layer of the epidermis. These cells repair minor injuries of the skin and replace dead skin cells. However, EpiSCs’ cannot heal severe wounds such as major burns or those from diabetes or hereditary disorders. In such cases, culturing the epidermal stem cells from the patient is possible and has yielded successful treatment options, such as laboratory-grown skin grafts. These grafts are synthesized using a patient’s own EpiSCs...
