E-mail: drtugbakevser@gmail.com Case Presentation A 68-year-old male presented with a 6-year history of a slowly growing ulcerated lesion on the scrotum. Dermato- logical examination revealed a polypoid lesion of 2 × 2 cm on an erythematous base on the left scrotum. The surface was ulcerated, and microbleeding spots were observed (Figure 1, A and B). No other lesions were present. Contact dermos- copy of the lesion revealed polymorphic linearly grouped dotted vessels and short linear vessels. Surface ulceration was prominent with the rope sign. Crystallite structures were evident in the left lower quadrant. (Figure 1C). The patient was referred for total excision. The histopathology revealed basal cell cancer of metatypical type (Figure 1D). No new lesions were observed in the biannual follow-up visit. Teaching Point Basal cell carcinoma is the most common type of cancer that is commonly seen on sun-exposed areas, yet it is rarely seen on the genitalia. Despite its rarity, genital basal cell carci- nomas have increased risk of distant metastasis. Therefore, after the initial therapy, long-term follow-up is mandatory in these cases. 2 Image Letter | Dermatol Pract Concept. 2022;12(1):e2022004 References 1. Han S, Zhang Y, Tian R, Guo K.
