We report two new cases of glomus coccygeum in pilonidal sinus excision specimens. The positive expression of glomus coccygeum cells for SOX10 is used for the first time. SOX10 is a useful immunohistochemical marker for identifying this microanatomical structure, confirming the diagnosis and may help the differential diagnosis. The glomus coccygeum cells are probably neural crest-derived from multipotent Schwann cell precursors.
