Linear Basal Cell Carcinoma of the Scrotum -A Case Report-

Although basal cell carcinoma (BCC) is the most common human malignancy, only 34 cases involving the scrotum have been previously reported. The linear type BCC is also an uncommon morphologic variant and was never reported over the scrotum. We describe a very rare case of linear BCC of the scrotum. A 70-year-old man noted an asymptomatic linear pigmented lesion over the scrotum for 4-5 years. As a resident of the blackfoot endemic area (Township Peimen), he reported to have been drinking higharsenic artesian well water for more than forty years and no history of sexually transmitted disease, previous trauma or radiotherapy to the scrotum. A skin biopsy revealed that was a mixed type BCC. The lesion was excised completely with a free margin of 0.6 cm of normal skin. There was no evidence of recurrence after a 4 months follow up . We did not detect any somatic mutation in PTCH gene.
