How Do You Differentiate Skin Disorders?
✔✔ Skin conditions are classified by morphology (appearance), distribution,
and progression. Accurate identification of primary vs. secondary lesions, lesion
shape, arrangement, location, and associated symptoms is essential for diagnosis.
Primary Skin Lesions (Initial Presentation)
✔ Macule: Flat, non-palpable change in skin color; <1 cm
✔ Patch: Flat and larger than a macule; >1 cm
✔ Papule: Small, raised, solid bump; <1 cm
✔ Plaque: Raised, flat-topped lesion; >1 cm
✔ Nodule: Solid, raised lesion deeper in the skin; >1 cm and involves dermis or
subcutaneous layer
✔ Tumor: Large, solid growth extending into deeper tissue layers
✔ Vesicle: Small fluid-filled blister; <1 cm
✔ Bulla: Large fluid-filled blister; >1 cm
✔ Pustule: Raised lesion containing pus
✔ Wheal: Transient, elevated area caused by localized edema (e.g., hives)
Secondary Skin Lesions (Result from Primary Lesions or Trauma)
✔ Include: Crusts, scales, fissures, ulcers, excoriations, scars, erosions,
lichenification
✔ Often result from scratching, infection, healing, or chronic inflammation
Topical Treatments for Acne
, ✔✔ Common first-line treatments include:
Benzoyl Peroxide: Antibacterial and keratolytic (helps unclog pores)
Topical Retinoids (e.g., tretinoin, adapalene): Normalize skin cell
turnover and reduce inflammation
Topical Antibiotics (e.g., clindamycin, erythromycin): Target
Cutibacterium acnes
Azelaic Acid: Antibacterial and helps with post-acne pigmentation
Salicylic Acid: Helps exfoliate and unclog pores
📌 Combination therapy (e.g., benzoyl peroxide + clindamycin) is often more
effective and helps reduce resistance.
Oral/Antibiotic Treatments for Acne
✔✔ Used for moderate to severe or inflammatory acne when topical treatments
are insufficient:
Doxycycline or Minocycline (first-line oral antibiotics)
Erythromycin (alternative if tetracyclines are contraindicated)
Oral contraceptives and spironolactone (for hormonal acne in females)
Isotretinoin (severe cystic acne; requires special prescribing guidelines due
to teratogenicity)
What are the requirements to prescribe Isotretinoin? - ANSWER✔✔How do you
qualify for isotretinoin?
All patients, including women who cannot become pregnant and men, can get
isotretinoin only if they are registered with iPLEDGE, have a prescription from a
doctor who is registered with iPLEDGE and fill the prescription at a pharmacy that
is registered with iPLEDGE The iPLEDGE REMS is a safety program to manage
the risk of isotretinoin's teratogenicity and to minimize fetal exposure.
