Identifying the potential origin of mucin in primary cutaneous mucinoses - a retrospective study and analysis using histopathology and multiplex fluorescence staining.

Various cell types seem to contribute to mucin production in PCM. Using MFS, we showed that CD8+ T-cells seem to be more involved in the production of mucin in FM than in dermal mucinoses, which could indicate that mucin in dermal and follicular epithelial mucinoses have different origins.
