Case 34 Male, 2 years. Skin lesion, lower armShow diagnosis & comments
Spitz naevus. with relatively large and pleomorphic cell type
The architectural and cellular features are indicative of Spitz naevus, but the copious cytoplasm of the cells shows little shrinkage artifact, and nuclei are somewhat irregular. When such features would be encountered in lesion from an adult, one might consider STUMP. In view of the young age of the patient and the very regular architecture of this lesion, a diagnosis of Spitz naevus was made.
