Excision of multiple eyelid apocrine hidrocystomas via an en-bloc lower eyelid blepharoplasty incision.

A 39-year-old man presented with upper and lower eyelid apocrine hidrocystomas that had recurred after each of three prior attempts at excision. These multiple, cystic tumors were adherent to the epidermis, thus precluding complete dissection and excision of each individual lesion. We report a surgical technique using a lower eyelid blepharoplasty incision to remove the confluent tumors of the lower eyelids en-bloc. We paid careful attention to both removing the lesions without rupturing the cysts and to achieving adequate depth of excision. Histology revealed features typical of apocrine hidrocystomas. The patient has remained free of recurrence three years since the en-bloc excision of the lesions.

Extraocular muscle metastasis 16 years following primary prostate carcinoma.

An 83-year-old man with a history of localized prostate carcinoma treated 16 years prior with transurethral partial prostatectomy and radioactive seed implants presented with a 2-month history of right globe proptosis. Computed tomography demonstrated a right medial rectus mass. Serum prostate specific antigen (PSA) level was normal. Tumor biopsy revealed poorly differentiated carcinoma with diffuse staining of tumor cells with PSA and prostatic acid phosphatase. This case demonstrates that prostate carcinoma may metastasize to an extraocular muscle many years after treatment of the primary tumor and may not be accompanied by elevated serum PSA. Immunohistochemical stains are helpful in establishing the diagnosis.
