Morphologic changes of a pigmented Spitz nevus assessed by dermoscopy

Journal of the American Academy of Dermatology, 2002
Pigmented Spitz nevus may simulate cutaneous melanoma clinically and histopathologically. In an effort to characterize Spitz nevi using dermoscopy, we documented the dermoscopic features of a single pigmented Spitz nevus over a 6-month period. A 3-year-old boy had a brownish black papule, 3 mm in diameter, on the dorsum of the first finger of his left ...

Spitz nevus with a novel TFG‐NTRK2 fusion: The first case report of NTRK2‐rearranged Spitz/Reed nevus

Journal of cutaneous pathology, 2021
Fusions of ALK, ROS1, NTRK1, NTRK3, RET, MET, MERTK, FGFR1, ERBB4, LCK, BRAF, MAP3K8, MAP3K3, and PRKDC and mutation of HRAS have so far been discovered as the genetic alterations associated with the pathogenesis of Spitz neoplasms.

Rhabdomyosarcoma in a Congenital Pigmented Nevus

Pediatric Pathology, 1992
A 7-month-old boy had a giant pigmented lesion involving the trunk and thighs that exhibited many hyperpigmented hairy and verrucous nevi. One of the nevi ulcerated and on histological examination consisted of pleomorphic rhabdomyosarcoma cells that stained for muscle-specific actin (HHF-35), desmin, and myoglobin.
