As found in one study of 86 individuals, GCF commonly present as single tumors in children less than 10 years old (62% of cases), 10-40 year old individuals (26% of cases), and adults greater that 40 years (12% of cases) (overall median age: 6 years). There is a strong predominance of males in the reported cases of GCF. The tumors are slow-growing, painless, often protuberant, multinodular or polyp-like dermal and subcutaneous tumors masses or plaques (i.e. a lesion that is greater in its diameter than in its depth) that commonly occur on the trunk, upper parts of the arms or legs, or, rarely, the head and neck areas.
