Role of Targeted Sequencing in Routine Diagnostics of Spitz Melanocytic Neoplasms-An Analysis of 70 Cases.
J Cutan Pathol
November 2024
Institute of Pathology, Faculty of Medicine, University of Ljubljana, Ljubljana, Slovenia.
Article Synopsis
- The Spitz group of melanocytic tumors should ideally include those with specific genomic changes like kinase receptor fusions and HRAS mutations, while traditional melanoma markers like BRAF mutations indicate a different diagnosis.
- A study involving 70 melanocytic tumors utilized targeted sequencing to differentiate between Spitz and conventional melanomas and clarify their classifications.
- The findings revealed substantial discrepancies in initial diagnoses, with 34% of cases having differing outcomes after molecular analysis, highlighting the need for genetic testing to improve diagnostic reliability in challenging cases.

Article Synopsis
- - The distinction between Spitz nevus and melanoma can be challenging due to their similar histopathologic features, such as large melanocytes with distinct cytoplasm and nuclei.
- - Advances in genomic studies have revealed that Spitz tumors have various genetic origins, leading to different categories of lesions (benign, intermediate, malignant), while some melanomas may resemble Spitz tumors but have typical initiating mutations.
- - The current WHO definition of Spitz tumors focuses on those with mutations in the MAP kinase pathway, aiming to clarify classification and guide treatment, especially for tumors prevalent in younger individuals.*
Spitzoid melanoma of the finger: a case report.
J Med Case Rep

Orthopedic Surgery and Traymatology, Habib Bourguiba Hospital, Sfax, Tunisia.
Background: Melanoma is the most malignant skin tumor, with a high metastatic potential. Spitzoid melanoma is a subtype of melanoma requiring rapid management and extensive tumor resection. We have set the goal to recognize anatomical peculiarities and difficulties diagnoses posed by this type of tumor, as well as to recognize the management modalities, especially the surgical one, of malignant spitzoid melanoma.

Article Synopsis
- Some doctors in the UK are careful about treating Spitz-type lesions in kids, often suggesting they should be removed to be safe.
- Researchers studied 91 kids with these lesions and found that most had harmless forms, and many did not need ongoing check-ups after treatment.
- The study showed that these lesions are usually not harmful, so doctors don't think aggressive treatments are needed for most kids with these skin spots.
