Spitz Nevus
Also known as: Spindle Cell Nevus, Epithelioid Cell Nevus
A dome-shaped pink or brown mole common in children. Can closely resemble melanoma under the microscope - often excised for certainty.

Spitz nevus
Pink dome, kids, fast growth
Spitz nevus is a distinctive type of benign melanocytic mole that most commonly occurs in children and teenagers, though it can appear at any age. It typically presents as a dome-shaped, well-defined, pink, red, or brown papule that grows relatively quickly to a size of 5-10mm.
The clinical and historical significance of Spitz nevi lies in their microscopic resemblance to melanoma. Under the microscope, Spitz nevi show features (spindle and epithelioid cells, mitotic activity) that can closely mimic melanoma - to the extent that they were historically called "juvenile melanoma" (a misleading term now abandoned).
Because of this diagnostic challenge, many dermatologists and dermatopathologists recommend complete excision of Spitz nevi, especially in adults. In children, where the risk of melanoma is extremely low, management may include monitoring in some cases.
Atypical Spitz tumors (those with some worrisome features but not definitive for melanoma) represent a diagnostic gray zone that may require sentinel lymph node biopsy and close follow-up.

Is a Spitz nevus melanoma?
No. Spitz nevi are benign moles. However, they can look similar to melanoma under the microscope, which is why they are often excised - for diagnostic certainty rather than because they are dangerous. True melanoma in children is extremely rare.
Should all Spitz nevi be removed?
In adults, most dermatologists recommend excision because the microscopic distinction from melanoma is more clinically significant. In children, where melanoma is extremely rare, some dermatologists may monitor rather than excise if the clinical presentation is classic for Spitz nevus.
