: A two-year-old female infant presented with a palpable scalp mass that her mother first noticed nine months before presentation.

On examination, she had a single, round, firm, subcutaneous mass measuring 3x2 cm on the right posterior temporal area covered by normal skin. Histology was consistent with cranial fasciitis.
