SKIN LESION, NECK, EXCISION: | |||
- GRANULAR CELL TUMOUR. | |||
- MILD SOLAR ELASTOSIS. | |||
COMMENT: | |||
The lesional cells stain as follows: | |||
POSITIVE: S-100, CD68, vimentin, calretinin. | |||
NEGATIVE: HMB-45. | |||
</pre> | |||
===Micro=== | |||
The sections show skin with nests of cells in the mid dermis, extending to the subcutis. The cells that make up the nests have an abundant granular grey cytoplasm, and round regular nuclei without obvious nucleoli. No mitotic activity is readily apparent. The lesional cells focally wrap around nerve. The superficial dermis has mild solar elastosis. The lesion is completely excised in the plane of section. | |||
