The best next step in this case is option B: Excision with safety margin. This patient has a small mass in the perianal region with a history of leukemia and completed chemotherapy. The biopsy shows pleomorphic changes (cellular abnormalities) in what was diagnosed as condyloma, which raises concern for potential malignant transformation. Although there are no distant metastases, the pleomorphic changes warrant complete removal of the lesion with adequate margins to ensure all abnormal tissue is removed. This approach is more appropriate than simple follow-up (which would be insufficient given the concerning pathology) but less aggressive than wide local excision with flap reconstruction (which would be excessive for a small localized lesion without metastasis). Additional chemotherapy is not indicated as the primary treatment for this localized skin lesion, especially since the patient has already completed a course of chemotherapy for leukemia. The excision with safety margin allows for complete pathological evaluation of the tissue and reduces the risk of local recurrence or progression to invasive disease, as supported by the most recent study 1.
Some key points to consider in the management of this patient include:
- The importance of complete removal of the lesion to prevent local recurrence and potential malignant transformation, as highlighted in the study 1.
- The need for adequate margins to ensure all abnormal tissue is removed, as discussed in the study 2.
- The role of surgical excision as a primary treatment for localized condyloma with concerning pathology, as supported by the study 3.
- The potential for malignant transformation in condyloma, especially in immunocompromised patients, as noted in the study 4.
Overall, the approach of excision with safety margin balances the need for complete removal of the lesion with the potential risks and benefits of more aggressive surgical approaches, and is supported by the most recent and highest quality evidence 1.
