Trichofolliculoma With Mucinosis

The document reported a case of a 54-year-old man with a trichofolliculoma, a benign hair follicle tumor, which exhibited an unusual feature of prominent mucinosis. Typically, trichofolliculomas present as solitary papules with secondary hair follicles, but in this case, there was an excessive presence of mucin, a mesenchymal component, which is not commonly observed in such abundance. This mucinosis was highlighted as a striking additional feature, reflecting an exaggeration of the mesenchymal component usually associated with this type of tumor. The findings emphasized the variability in the presentation of trichofolliculomas and the potential for significant mucin deposition.
