Folliculogenesis01:20

Folliculogenesis

3.4K
Folliculogenesis is the development of ovarian follicles, the specialized structures within the ovarian cortex where oogenesis, or egg development, occurs. This process is essential for female reproductive health and begins during fetal development when primordial follicles are formed. Each primordial follicle comprises a primary oocyte in the center, surrounded by a single layer of squamous pre-granulosa cells. These follicles remain dormant in late prophase I of meiosis until triggered by...

Multipotency and Niche of Bulge Stem Cell

4.4K
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...

The Thyroid Gland01:23

The Thyroid Gland

8.6K
The thyroid gland is a small, butterfly-shaped gland located in the neck and covers the anterior surface of the trachea. The gland has two lateral lobes connected by a thin tissue mass called the isthmus. Internally, each lobe comprises many small spherical structures known as thyroid follicles, surrounded by a network of blood vessels.
The follicles have a central cavity lined by simple cuboidal to squamous epithelial cells called follicular cells. These cells produce the glycoprotein...

Ovarian Cycle01:27

Ovarian Cycle

5.2K
The menstrual cycle includes a critical component known as the ovarian cycle, which undergoes two main phases each month—the follicular phase and the luteal phase. The follicular phase is variable and averaging around 14 days. Ovulation, triggered by a surge in luteinizing hormone (LH), marks the transition between the two phases. The second phase, the luteal phase, is relatively consistent, lasting approximately 14 days, and is marked by the activity of the corpus luteum. While a cycle...

Summary
This summary is machine-generated.

Benign follicular tumors, often single skin lesions, can be multiple and signal cancer-prone syndromes. Dermatologists play a key role in recognizing these tumors for timely diagnosis and genetic counseling.

Area of Science:

  • Dermatopathology
  • Oncology
  • Genetics

Background:

  • Benign follicular tumors are neoplasms with hair follicle differentiation.
  • While typically solitary and dermatologically relevant, multiple lesions can indicate underlying cancer syndromes.
  • Understanding hair follicle embryology and histology is crucial for diagnosing these tumors.

Purpose of the Study:

  • To review the clinicopathological features and differential diagnosis of benign follicular tumors.
  • To discuss syndromes associated with multiple follicular tumors.
  • To emphasize the dermatologist's role in early detection and management.

Main Methods:

  • Histological examination of benign follicular tumors.
  • Clinicopathological correlation.
  • Review of syndromes associated with multiple follicular tumors.

Main Results:

  • Detailed microscopic structure of normal hair follicle provided as a diagnostic basis.
  • Key benign follicular tumors discussed: dilated pore of Winer, trichilemmoma, trichoblastoma, pilomatricoma, etc.
  • Syndromes like Cowden, Birt-Hogg-Dubé, and Rombo highlighted as associated with multiple follicular tumors.

Conclusions:

  • Diagnosis of follicular tumors relies on histology.
  • Recognizing multiple follicular tumors is vital for identifying patients at risk for visceral neoplasms.
  • Dermatologists are pivotal in early detection, referral, and genetic counseling for these patients.
