Contrast-enhanced whole body joint MR imaging in rheumatoid patients on tumour necrosis factor-alpha agents: a pilot study to evaluate novel scoring system for MR synovitis.

Primary cutaneous mucinous carcinoma of the scalp is a rare tumor deriving from the sweat glands. It is typically located on the head and is often mistaken for a metastasis from a more common primary tumor of the breast or gastrointestinal tract. We report a case in a 54-year-old female, who presented with a slow growing mass near the right frontoparietal region of the scalp. An incisional biopsy of the lesion revealed mucinous carcinoma of the skin. Investigations excluded the possibility of metastatic mucinous carcinoma. Thus, the lesion in the lateral canthus region was diagnosed as primary mucinous carcinoma of the skin, a slow-growing tumor which rarely metastasizes and is associated with low mortality. The patient was managed with a wide excision and split skin graft of the scalp. The patient is doing well after 36 months of follow-up.
