Summary
Epidermal cysts, common skin tumors, rarely ossify. This case highlights focal ossification near an epidermal cyst, suggesting chronic inflammation as a potential cause.
Area of Science:
- Dermatology
- Pathology
Background:
- Epidermal cysts are benign skin neoplasms originating from hair follicles.
- Ossification within or around epidermal cysts is an exceptionally rare phenomenon.
Purpose of the Study:
- To report a rare case of epidermal cyst with associated ossification.
- To discuss the potential mechanism and diagnostic implications of this finding.
Main Methods:
- Clinical presentation of a 68-year-old male with multiple cutaneous cysts.
- Histopathological examination of excised cysts.
- Analysis of the cyst wall and surrounding tissue for ossification.
Main Results:
- Histopathology confirmed epidermal cysts on the forehead, cheek, and shoulder.
- Focal ossification was identified adjacent to the epidermal cyst on the forehead.
- No other neoplastic or inflammatory conditions were noted in the vicinity.
Conclusions:
- Epidermal cysts can rarely exhibit ossification, particularly in the context of chronic inflammation.
- This case expands the differential diagnosis for cutaneous ossified lesions.
- Consider epidermal cysts in the differential diagnosis of ossified cysts.

6.5K
Meaning of Cystoscopic Examination:Cystoscopy is an essential diagnostic tool in urology that is used to assess the structure and function of the genitourinary system. It provides a direct view of the urethra, bladder, and, in some cases, the ureteral openings. This procedure helps detect structural abnormalities, infections, cancers, and blockages in the urinary tract. There are two types of cystoscopy:Flexible cystoscopy is commonly performed in outpatient settings due to its less invasive...

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...

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.

01:29Bone Formation by Intramembranous Ossification
16.1K
Intramembranous ossification is one of the two processes involved in the development of bones within an embryo. The flat bones of the face, most of the cranial bones, and the clavicles are formed via this process. During intramembranous ossification, the bones develop directly from sheets of undifferentiated mesenchymal connective tissue.
The process begins when mesenchymal cells in the embryonic skeleton gather together and differentiate into osteogenic cells, which then develop into ...

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...
