Background: Basal cell carcinoma (BCC) is the most frequent non-melanoma skin malignancy globally, typically characterized by slow, locally invasive growth with a low propensity for distant metastasis. Among its distinct histopathological variants, the adenoid variant of nodular BCC is a relatively uncommon presentation that can mimic glandular structures or other cutaneous adnexal tumors. Case Presentation: We present the case of a 53-year-old female who presented with a blackish, warty, nodular, ulcero-proliferative growth measuring 2.2 x 2cm, located 2 cm lateral to the right angle of the mouth, evolving over 2 years. The patient had a relevant medical history of long-standing epilepsy and recently diagnosed diabetes mellitus. Local examination revealed classic BCC features, including central depression, a beaded appearance, and rolled-out edges. A wide local excision was performed via a curvilinear elliptical incision aligned with the right nasolabial fold, achieving clear surgical margins. Histopathological evaluation confirmed a nodular basal cell carcinoma with prominent adenoid (cribriform and cystic) differentiation, characterized by peripheral palisading and retraction clefts. The postoperative period was uneventful, and primary closure yielded excellent cosmetic results. Conclusion: The adenoid variant of nodular BCC represents a unique histopathological subtype. Wide local excision with adequate oncological margins remains the cornerstone of treatment, providing excellent long-term prognosis and exceptional local control.
