Hypopigmented atypical Spitzoid neoplasms (atypical Spitz nevi, atypical Spitz tumors, Spitzoid melanoma): a clinicopathological update
The clinicopathologic classification, diagnosis, and management of Spitzoid melanocytic lesions is one of the most problematic topics in dermato-oncology and dermatopathology. After earlier anecdotal reports [1,2], the controversial history of these controversial lesions began in 1948 when Sophie Spitz described 13 cases of what she called “juvenile melanoma,” underlining its presumably good pr...
متن کاملAtypical Spitz Tumor of Uncertain Biologic Potential with Inopportune Localization in a 7-year-old Boy.
The Spitz nevus was first described as the “melanoma of childhood” or “juvenile melanoma” by Sophie Spitz in 1948 (1). Most spitzoid melanocytic proliferations can be classified as benign Spitz nevi or spitzoid melanomas based on published criteria (2-3). However, a subset of spitzoid lesions have histological features that deviate from a typical Spitz nevus, yet are insufficient for a definiti...
متن کاملThe atypical Spitz tumor of uncertain biologic potential: a series of 67 patients from a single institution.
BACKGROUND Atypical Spitz tumors (AST) are rare spitzoid melanocytic proliferations with an uncertain malignant potential. ASTs have overlapping features of both Spitz nevi and spitzoid melanoma, and consequently generate controversy with diagnosis and management. Sentinel lymph node biopsy (SLNB) has been proposed as a possible means to gain additional insight into the true biologic potential ...
متن کاملAtypical Spitz Nevi: A Case Report and Review of the Literature
A case of atypical ("pagetoid") compound Spitz nevus on the face of a 2-year-old girl is reported with a review of the literature. The nevus was composed of broad but laterally demarcated compound proliferation of enlarged fusiform and epithelioid melanocytes, with florid pagetoid scatter above the junction. Immunohistochemical analyses revealed the Ki-67 proliferation index to be relatively lo...
متن کاملAtypical Presentation of Atypical Teratoid Rhabdoid Tumor in a Child
Atypical Teratoid Rhabdoid Tumor (ATRT) is a rare malignant intracranial neoplasm more commonly diagnosed in young children. The authors report the case of an 11-year-old boy with a long standing history of slowly progressive weight loss, fatigue, and weakness over 1.5 years whose magnetic resonance imaging revealed a large heterogeneous enhancing dorsally exophytic lower brainstem mass. Examin...
