Management of a Large Facial Basal Cell Carcinoma in an Elderly Patient with Multiple Comorbidities
An 82-year-old woman presents with a 3.5 cm basal cell carcinoma (BCC) on the left cheek, extending from the infraorbital rim to the nasolabial fold. The tumor is ulcerated and has been growing slowly over 5 years. She has a history of hypertension, stage 3 chronic kidney disease, and mild cognitive impairment. She lives alone and has a daughter who assists with care. She is on aspirin 81 mg daily for primary prevention and has a history of falls. Physical examination shows a large, friable tumor with indistinct borders. There is no facial nerve involvement. She is otherwise healthy for her age. The plastic surgery team is consulted for management. The patient is unsure about surgery and is concerned about recovery time and the risk of complications.
1. What are the treatment options for this patient, and what factors should guide the decision? Discuss the role of Mohs surgery versus wide local excision, and the considerations for reconstruction.

Treatment options for a large BCC include surgical excision (Mohs micrographic surgery or wide local excision with frozen section control), radiation therapy, and topical therapy (imiquimod, 5-fluorouracil) or photodynamic therapy (not suitable for large, invasive tumors). Given the size, location, and ulceration, surgical excision is the mainstay.
Mohs surgery offers the highest cure rate and maximal tissue conservation, which is important in this cosmetically and functionally sensitive area (cheek, near the eye and mouth). However, Mohs requires multiple stages and may be logistically difficult for an 82-year-old with mild cognitive impairment and transportation issues. Wide local excision with frozen section control is an alternative, but it may require a larger margin and potentially more complex reconstruction. For a 3.5 cm BCC, a 4-5 mm margin is recommended for low-risk subtypes, but the indistinct borders suggest a more aggressive subtype (e.g., morpheaform or infiltrative), which may require wider margins (5-10 mm).
Factors guiding the decision include: patient preference, life expectancy, comorbidities, cognitive status, social support, and the ability to comply with follow-up. The patient's concern about recovery time and complications is valid. Her aspirin use increases bleeding risk but is for primary prevention; it can be continued in most cutaneous surgery. Her CKD stage 3 may affect drug metabolism and wound healing but is not a contraindication.
Reconstruction options after excision include primary closure (if feasible), local flaps (e.g., rhomboid, bilobed, nasolabial), skin grafts, or healing by secondary intention. Given the size and location, a local flap (e.g., cheek advancement or rotation) may be needed. The choice depends on the defect size and location after excision. Mohs may allow smaller defects and simpler closures. If Mohs is not feasible, wide local excision with frozen section and immediate reconstruction by plastic surgery is appropriate.
Radiation therapy is an option for patients who are poor surgical candidates, but it requires daily treatments for several weeks and may be burdensome. It also has risks of radionecrosis and poor cosmesis. Given her cognitive impairment, compliance may be an issue.
In summary, the decision should be individualized, weighing the high cure rate and tissue conservation of Mohs against the logistical challenges. A multidisciplinary approach involving dermatology, plastic surgery, and the patient's family is essential.
2. If the patient undergoes surgical excision, what are the key perioperative considerations to optimize outcomes and minimize complications? Include discussion of anticoagulation management, anesthesia choice, and postoperative care.

Perioperative considerations:
Anticoagulation: Aspirin 81 mg for primary prevention can typically be continued during skin surgery, as the risk of bleeding is low and the risk of cardiovascular events if stopped may outweigh benefits. However, given her age and fall risk, the surgeon may choose to hold aspirin for 3-5 days preoperatively after consulting with her primary care physician. If held, it should be restarted promptly postoperatively. Other anticoagulants are not mentioned.
Anesthesia: Local anesthesia with monitored anesthesia care (MAC) is preferred to avoid general anesthesia risks in an elderly patient with cognitive impairment. However, the size and location may require a field block or regional block. If general anesthesia is needed, careful preoperative assessment is necessary. The patient's CKD may affect drug clearance, so anesthetic agents should be chosen carefully.
Surgical planning: Wide local excision with frozen section control to ensure clear margins. Reconstruction should be planned to minimize complexity and recovery time. A simple local flap or graft may be preferable to a complex multi-stage procedure. The patient's cognitive impairment may affect her ability to cooperate with postoperative care, so a simpler reconstruction may be better.
Postoperative care: Wound care instructions should be clear and written, with involvement of the daughter. Follow-up should be scheduled early to check the wound and remove sutures. Pain management should be adequate but avoid opioids if possible due to fall risk and cognitive impairment. Acetaminophen is preferred.
Fall precautions: The patient has a history of falls; assess gait and balance, and provide assistance with ambulation postoperatively.
Nutrition and hydration: Ensure adequate intake to promote wound healing.
Surveillance: Regular skin checks for recurrence and new lesions.
By addressing these factors, the risk of complications can be minimized and the patient's recovery optimized.
