A 65-year-old male with a right lower eyelid mass had history of adenocarcinoma of the left orbit, status post radiation therapy, followed by left orbital exenteration, 12 years prior to presentation at MDACC. An MRI of the orbit, face, and neck performed at MDACC demonstrated a thickened enhancing lesion adjacent to the right nasolacrimal duct measuring 4.1 × 1.0 cm () which extends from the medial canthus to the lateral inferior periorbital soft tissue. In addition, mildly thickened soft tissue enhancement along the left premolar soft tissues suspicious for recurrent disease was reported. Prior positron emission tomography (PET)/CT scan and MRI of the brain performed in an outside facility failed to demonstrate second primary or metastatic disease. Wide local excision of the right lower eyelid and cheek mass was performed with intraoperative margin assessment showing positive margins. Microscopically, cords of histiocytoid cells arising from eccrine glands were identified infiltrating skeletal muscle and orbit with extensive perineural invasion (). Surgical margins were positive. Five months after completion of radiation therapy, the patient noted a new right upper eyelid nodule. A CT scan of head and neck reveals local right retroorbital recurrence and left neck adenopathy. A more radical surgery for the right orbit was avoided due to the cancer demonstrating a very slow growth pattern, and it would render him totally blind.\nFour years of documented follow-up (until January 2019, when the patient was last contacted at MDACC) after the first surgery done for the lower eyelid mass, he was still alive. Currently, the patient is being seen at an outside facility with his only eye globe intact. He has had slowly progressive distant lymph node metastatic disease for which standard treatments have not been offered, and he is not keen to enroll in clinical trials.
A 67-year old female presented with a smooth, solitary lump on scalp in the right occipital region (Figure ).\nOn examination, a 3 x 3 cm smooth, firm, non-mobile lump was palpable with overlying scalp hair. The initial impression was that of a sebaceous cyst and she was advised to wait and watch for any changes to the features of the lesion or development of any new symptoms. On review after six months, the size of the lesion increased to 4 x 4 cm and the patient reported progressively worsening itching on the overlying skin. A decision was made to completely excise the cyst. Histopathological analysis from the lesion confirmed a mucinous eccrine carcinoma of skin (Figures , ).
