Insights

Epidermal inclusion cysts can form from skin cell implantation. This case shows such a cyst developing after surgery for benign fibrous histiocytoma.

Area of Science:

  • Dermatology
  • Pathology
  • Surgical Oncology

Background:

  • Epidermal inclusion cysts (EICs) are commonly caused by epidermal implantation.
  • Recurrent benign fibrous histiocytoma (BFH) is a soft tissue tumor requiring surgical intervention.

Purpose of the Study:

  • To present a case illustrating EIC formation via implantation.
  • To highlight a potential complication in post-surgical BFH cases.

Main Methods:

  • Case report analysis.
  • Histopathological examination of the cyst and surrounding tissue.

Main Results:

  • An epidermal inclusion cyst was identified.
  • Evidence of epidermal implantation into the dermis was observed.
  • The cyst was associated with a site of previous BFH excision.

Conclusions:

  • Surgical manipulation can lead to epidermal implantation and subsequent EIC formation.
  • EICs should be considered in the differential diagnosis of subcutaneous lesions following surgery for BFH.

Skin Cancer01:30

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.
Basal Cell Carcinoma (BCC): BCC is the most common type of skin cancer, accounting for about 80% of cases. It typically develops in...

Acne Infection01:27

Acne Infection

Acne is a multifactorial skin condition primarily affecting adolescents and young adults, with a global prevalence estimated to exceed 75% in this demographic. The condition is characterized by the formation of comedones (blackheads and whiteheads), papules, pustules, nodules, and, in severe cases, cysts, particularly in areas rich in sebaceous glands such as the face, neck, chest, and back. The pathogenesis involves increased sebum production, follicular hyperkeratinization, colonization by...

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...

Chronic Inflammation: Introduction01:12

Chronic Inflammation: Introduction

Chronic inflammation is a prolonged, dysregulated immune response that persists for weeks to years when the inciting stimulus is difficult to eradicate or when self‑antigens drive ongoing reactivity. Morphologically, it is defined by mononuclear cell infiltration, progressive tissue destruction, and concurrent attempts at healing via angiogenesis and fibrosis. Compared with acute inflammation, edema is less prominent while cellular infiltration predominates; triggers include persistent...
