Abstract: Two cases of follicular mucinosis were reported and the literature was reviewed. The first patient was a 44-year-old male who presented with a two-month history of localized infiltrative erythema on the neck．Histopathological examination showed that the epithelium of the follicle was edematous, and accumulation of mucin located adjacent to the follicle. Lymphocytes and some eosinophils were infiltrated. Alcian blue staining showed mucin deposited in follicles. The second patient was a 32-year-old man presented with a forty-five-day history of infiltrated dark erythema on the left face. Histopathological examination showed that the epidermis was generally normal, the epithelium of the follicle was edematous, and accumulation of mucin located adjacent to the follicle. Eosinophils and some lymphocytes were infiltrated. Alcian blue staining showed mucin deposited in follicles.

Key words: infiltrative erythema, follicular mucinosis
