External Female Genitals01:15

External Female Genitals

36.8K
The vulva encompasses the external structures of the female reproductive system. At the forefront is the monpubis, a cushion of fatty tissue atop the pubic bone. Once puberty sets in, this area typically grows hair. Extending from just behind the mons pubis are the labia majora (labia = 'lips'; majora = 'larger'), which are larger skin fs olds coated with hair. Nestled within are the labia minora (labia = 'lips'; minora = 'smaller'), which are thinner, more...

Vagina01:26

Vagina

36.7K
The vaginal canal is a tubular structure averaging about 10 cm in length that acts as the entryway to the female reproductive system and the passageway for menstrual flow and childbirth. The interior walls of the vagina exhibit concentric folds called rugae and are topped by an area known as the fornix, which connects with the protruding cervical portion of the uterus. This canal is comprised of an external fibrous layer, a muscular middle layer, and an inner lining with mucosal rugae, which...

Assessment of the Rectum and Anus

1.4K
Evaluating the rectum and anus plays a crucial role in conducting a thorough physical examination of the gastrointestinal system. Although it may be uncomfortable and often embarrassing for the patient, it holds immense diagnostic value, particularly in detecting gastrointestinal diseases and abnormalities. This guide will explain how to perform this assessment using inspection and palpation methods.
Rectal Inspection
Begin by inspecting the perianal and anal areas for color, texture, rashes,...

Uterus and Cervix01:18

Uterus and Cervix

5.6K
The uterus, commonly called the womb, is a vital reproductive organ in females designed to provide a nurturing environment for the implantation and growth of an embryo. It is shaped like a hollow pear and positioned between the urinary bladder and the rectum. The uterus's structure allows it to support and protect a developing fetus throughout pregnancy.
The uterus is securely anchored within the pelvic cavity by paired broad ligaments on either side. It is further stabilized by three pairs...

Urologic Endoscopic Procedure: Cystoscopic Examination

3.5K
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...

Papillary Dermis01:11

Papillary Dermis

6.0K
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...

Summary
This summary is machine-generated.

Isolated perineal verrucous lichen planus (VLP) is rare, but this case study shows it can occur without other mucocutaneous lesions. Effective treatment with potent topical corticosteroids led to a favorable outcome and no recurrence.

Area of Science:

  • Dermatology
  • Pathology

Background:

  • Verrucous lichen planus (VLP) is a chronic inflammatory skin condition typically affecting lower limbs.
  • VLP rarely presents in the perineal area, usually alongside other mucocutaneous lichen lesions.

Observation:

  • A 51-year-old patient presented with an 8-year history of isolated, painless, verrucous perineal lesions.
  • Clinical examination revealed firm, grayish, rough-surfaced lesions in the perianal and scrotal regions.
  • Histopathology confirmed verrucous epidermal changes, lymphocytic infiltrate, and pigmentary incontinence, ruling out infection or malignancy.

Findings:

  • The diagnosis of isolated perineal verrucous lichen planus was established.
  • Standard investigations for associated conditions (Hepatitis C, lipids, abdominal ultrasound) were negative.
  • Treatment with potent topical corticosteroids resulted in a favorable clinical outcome.

Implications:

  • This case highlights that VLP can manifest solely in the perineal region.
  • It underscores the efficacy of aggressive topical corticosteroid therapy for isolated perineal VLP.
  • The findings support prompt diagnosis and management to prevent recurrence.
