Nasal deformity accompanying upper lip sebaceous carcinoma without neoplasm extension

Sebaceous carcinoma is very rare, occurring in less than 1% of cutaneous neoplasm. it may have numerous clinical presentations but typically appears as yellow or orange firm nodule in periorbital region. in the absence of usual clinical manifestations, diagnosis is difficult which calls for more studies to help with definitive diagnosis. we report an 81-year-old man whose sebaceous carcinoma was diagnosed by histopathologic and immunohistochemical studies. our patient had clinical presentation as erythematous tumoral lesion, the unusual location of the lesion on the upper lip, very close to the nose, and nasal deformation similar to rosacea without any extension of tumour cells into nasal area. the mechanism by which sebaceous carcinoma resulted in nasal deformation is not clear
