What is the follow up for squamous cell
Requires through examination of cervical lymph nodes
Regular follow-up is required
Sooner if any recurrence of the lesion
A pt presents with a pigmented lesion On the ear
Think..
Malignant melanoma
Assoc. with high mortality
What does ABCDE stand for
Asymmetry Border Color Diameter Evolving
Determine if its a mole or melanoma
What is the Tx for malignant melanoma
Treatment
-Early detection and excision
+/- lymph node dissection
Prognosis
- Thin (epidermis) <10% risk of mets
- Thick (dermis) >90% risk of mets
What is an auricular hematoma
Soft mass in the ear
(boxers ear, wrestler)
Occurs after trauma from sheering forces
- blood vessels are torn
- forms hematoma
