Ashfaq Marghoob, MD
Are you performing dermsocopy in your clinical practice? Dr Marghoob provides us with his clinical pearls…
- Dermoscopy helps in differentiating benign lesions from skin cancer.
- The presence of network (reticular network, negative network, polygonal lines), streaks (radial streaming, pseudopods), aggregated globules/peripheral globules, homogeneous blue pigmentation is most often seen in melanocytic lesions.
- Melanocytic lesions that deviate from the 10 benign patterns and has at least one of the 10 melanoma-specific structures needs to be biopsied to rule out melanoma.
- The presence of spoke wheel structures and/or leaf like areas is 100% specific for BCC.
- Comedo like openings and milia cyst are often seen in SK but can also be seen in other lesions including melanoma.
- Polarized light makes blood vessels and crystalline structures more conspicious, and makes milia cyst less conspicuous.
- A polymorphous vascular pattern in an amelanotic lesion should raise concern for melanoma.
- Dermoscopy improves the clinician’s diagnostic accuracy.
- All structureless or featureless or not-otherwise-diagnosable lesions should be viewed with suspicion.
- Raised lesions should never be monitored for change.
