Insights

Pseudoverrucous papules and nodules are a skin reaction to irritation, often seen with urostomies. This condition, previously undescribed in perianal areas, can mimic serious dermatoses but resolves when the irritant is removed.

Area of Science:

  • Dermatology
  • Pediatrics

Background:

  • Pseudoverrucous papules and nodules (PVPN) were initially documented as a response to irritation from urostomies.
  • Previous literature has not described PVPN occurring on perianal skin or around colostomies.

Observation:

  • A distinct rash of shiny, smooth, red, moist, flat-topped papules and nodules (2-8 mm) was observed on the perianal and suprapubic skin of five children.
  • The lesions are attributed to chronic exposure from encopresis or urinary incontinence.
  • Histopathological examination revealed reactive acanthosis or psoriasiform spongiotic dermatitis.

Findings:

  • The observed skin lesions represent a previously unreported presentation of pseudoverrucous papules and nodules in the perianal region.
  • The morphology of the lesions is characterized by multiple, small, moist, and erythematous papules and nodules.
  • Resolution of the lesions was achieved by eliminating the causative irritant.

Implications:

  • Prompt recognition of this pseudoverrucous condition is crucial to prevent misdiagnosis and unnecessary investigations for more severe dermatological conditions.
  • This finding suggests that PVPN may be an underrecognized dermatosis in pediatric patients with incontinence.
  • Understanding the etiology and clinical presentation aids in appropriate management and avoids invasive diagnostic procedures.

Papillary Dermis01:11

Papillary Dermis

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 and...
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...
Assessment of the Rectum and Anus01:25

Assessment of the Rectum and Anus

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,...
Appendicitis-I: Introduction01:22

Appendicitis-I: Introduction

The appendix, a small, narrow, blind tube extending from the inferior part of the cecum, is widely regarded as a vestigial organ, having lost much of its original function through evolution. Despite its diminished role, the appendix can become inflamed, a condition known as appendicitis.
Etiology: Appendicitis can arise from various causes, primarily rooted in the obstruction of the appendix lumen. Factors contributing to this obstruction include fecal accumulation, lymphoid hyperplasia and, 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...
Appendicitis01:19

Appendicitis

Appendicitis is an acute inflammatory condition of the vermiform appendix, most commonly caused by obstruction of its lumen. The appendix is a narrow, blind-ended pouch that extends from the cecum, making it particularly prone to obstruction. Causes include fecaliths, lymphoid hyperplasia (often after viral infections), parasites, tumors, or foreign bodies. This obstruction initiates a cascade of pathological changes.Luminal Obstruction and Early InflammationAfter obstruction, normal mucosal...
