Melanocytes located between the anal transition zone and the dentate line of the anal canal can give rise to the uncommon malignant tumor known as anal melanoma. It has a fast-paced clinical course and can masquerade as several common anorectal symptoms, such as hemorrhoids or rectal ulcers. In melanoma, divergent differentiation is a very uncommon phenomenon.

- Peripheral nerve sheath tumors include benign types like schwannomas and neurofibromas, with diagnostic challenges often arising in core needle biopsies, where immunohistochemistry (IHC) can help clarify difficult cases.
- A study of 45 benign peripheral nerve sheath tumors found diverse variants, and employed IHC staining using S-100, CD56, and calretinin to analyze tumor samples.
- The findings revealed that while S-100 showed no significant differences between tumor types, CD56 and calretinin presented significant differential expression, suggesting CD56 may serve as a useful marker for distinguishing schwannomas from neurofibromas.
