Question

Procedure: The patient, a 28-year-old Hispanic male, was brought to the operating room and placed in the supine position. Under nasal prong oxygen and cardiac monitoring, the right lower lid and surrounding area were anesthetized. The right face was prepped in the routine manner. The head and body were draped to expose the right eye. Two, approximately 1.5-2.0-mm, round nodular ulcers centrally cratered, indurated lesions were outlined on the right lower lid not extending above the lateral canthal line. Medial to these lesions was a large milium . A pentagonal incision was outlined incorporating approximately 1 cm of lid margin. A horizontal lateral canthotomy [surgical division of the slit between the eyelids] was made, and the tissue below it was undermined. The pentagonal incision, with the base being the lid margin, was then excised by outlining with mosquito forceps followed by scissors excision. Hemostasis was achieved with bipolar cautery.

The lateral canthal flap was further undermined, and the lateral canthal skin incision was extended approximately 0.5 cm temporally. The medial lid margin was then sutured to the lateral canthal ligament. The horizontal incision of the lateral canthotomy was closed, and pentagonal lid gap was closed. Tobradex ointment and Telfa pad was placed and ice applied. The patient tolerated the operation well and left the operating room in satisfactory condition.

PATHOLOGY REPORT

Clinical Data: Rule out malignancy, lesion of eyelid.

Diagnosis: Basal Cell Carcinoma.

Specimen Site: Eyelid.

Gross Description: The specimen is received in formalin and labeled with the patient's name. It consists of a 0.1-cm punch biopsy of light-tan, wrinkled skin excised to a depth of 0.2 cm. On the surface, there is an irregularly pigmented area measuring 0.1 cm. Entirely submitted.

Microscopic Description: Sections of the submitted skin biopsy show a multicentric basal cell carcinoma. The tumor is formed by masses of small, darkly basophilic, ovoid cells that tend to palisade around the periphery. Marked basophilic degeneration of collagen is seen in the dermis. There is focal lymphocytic infiltration of the dermis. The tumor extends to margins of the biopsy.
