⭐ QUIZ 2 — COMPREHENSIVE STUDY GUIDE
I. SKIN DISORDERS (MODULE 3)



1. Malignant Skin Lesions

Basal Cell Carcinoma (BCC)

 Pearly or waxy papule or nodule

 Rolled/raised borders

 Telangiectasias

 May ulcerate (“rodent ulcer”)

 Slow-growing, rarely metastasizes

 Sun-exposed areas: face, scalp, ears, neck, shoulders
Treatment: biopsy; Mohs for high-risk; excision or cryotherapy



Squamous Cell Carcinoma (SCC)

 Flat, red, scaly or crusted lesion

 May ulcerate and not heal

 Faster growing than BCC

 More aggressive; can metastasize

 Sun-exposed areas or chronically inflamed skin
Treatment: biopsy; Mohs for high-risk lesions



Malignant Melanoma

 Arises from melanocytes

 Highly aggressive

 Asymmetric, irregular borders

 Color variation

 Often >6 mm

,  Evolving lesion
ABCD(E): Asymmetry, Border irregularity, Color variation, Diameter,
Evolving
Treatment: biopsy + urgent dermatology referral



2. Non-Malignant Skin Lesions

Actinic Keratosis

 Premalignant; may progress to SCC

Acrochordon (Skin Tags)

 Pedunculated, soft growths

 Occur in skin folds

 Associated with obesity/diabetes
Treatment: excision, electrocautery, cryotherapy

Cherry Angioma

 Small red-purple vascular papules

 Increase with age

 Always benign
Treatment: cosmetic only

Warts (Verrucae)

 Caused by HPV

 Rough, raised, cauliflower-like
Treatment: salicylic acid, cryotherapy, excision, immune therapy



II. NAIL DISORDERS



Onychomycosis

 Cause: Trichophyton rubrum
