Introduction:

Scleroderma syndromes are defined by the presence of skin sclerosis, induration and loss of skin elasticity. Their differential diagnosis includes cases of localized scleroderma, within which lichen sclerosus et atrophicus are described, which, to date, have not been recognized in the setting of paraneoplastic skin syndromes.

Results:

We present the case of a patient with advanced adenocarcinoma of the prostate, who developed cutaneous lesions compatible with extragenital lichen sclerosus et atrophicus during the course of the cancer, confirmed by histopathology.

Conclusions:

The paraneoplastic nature of this skin entity is questioned in this particular clinical context.
