“…This scaly appearance prompted us to consider a diagnosis of squamous cell carcinoma in situ, despite the lesion being in a non-photoexposed area [ 4 ]. The most frequently described sites are the buttocks (5/22, 22.7%) and lower limbs (16/22, 72.7%), mainly the thigh (5/22, 22.7%), hip (4/22, 18.2%), and calf (3/22, 13.6%), although there is one case of involvement of the shoulder (1/22, 4.5%), which had two more lesions on the hip and buttocks [ 1 , 2 , 3 ]. The lesions described to date were asymptomatic and indolent, however, our case presented occasional episodes of bleeding, although without associated pain or pruritus.…”
