@NadalAlfons Congratulations!

[Jeffrey Cloutier, MD, PhD @JCloutierMD]

🔬 Delighted to share our new @ModernPathology study on NRAS-amplified melanocytic tumors! Blending Spitz features with low-CSD genetics, they present challenges for classification. Now available open access!

@RashDecisionz @redsnapperpath @mreyesm Melanoma arising in CMN in young children usually represents intradermal nodule, but not SSM-like proliferation (indeed, it can happen in older children and adults).

[Irina Kletskaya @ikletskaya]

@RashDecisionz @redsnapperpath @mreyesm Good question! Atypical junctional proliferation is well-known to occur in CMN, however dermal proliferation (PN in CMN) is found more often. Melanoma arising in CMN almost never occurs under 6 months (and there are additional criteria like distant mets to confirm the diagnosis)

[Irina Kletskaya @ikletskaya]

@FJMazorra @mreyesm not in this case. Usually NCM is associated with posteroaxial localization and number of satellite nevi may be also predictive.

Solitary cutaneous mastocytoma
✔️ Infants; single lesion
✔️ Rare variant of mastocytosis
🔎 Dermal mast cell aggregates (fried egg-look); granular cytoplasm
❗ Mimics melanocytic nevi

BIPHENOTYPIC SINONASAL SARCOMA. IHC: S100 (negative for desmin and myogenin [not shown]). NGS: PAX3-MAML3. NB: infiltrative spindle cell neoplasm with herringbone pattern; monomorphic elongated ovoid nuclei; entrapment of benign glands is relatively common (PMID: 30829729).

Our latest research on IMTs shows how deceptive they can be in infants. #PediPath @rita_alaggio @LeaSurrey https://t.co/QkrSSP4MJ8
