Abstract
|
|
|
A clinical and histological study of typical sebaceous epithelioma (basal cell epithelioma with sebaceous differentiation) developed secondarily in lesions of nevus sebaceus of Jadassohn is presented. The patient was 42 years old male.
The sebaceous epithelioma tends to have about the same clinical characteristics as undifferentiated basal cell epithelioma but it is more often a yellow color.
Sebaceous epithelioma may arise from nevus sebaceus and it is precursor of undifferentiated basal cell epithelioma.
Histologically, the preparation showed massive development of sebaceous gland, papillomatous epidermal hyperplasia and maturation of apocrine glands.
The tumor cell nests were mostly composed of large sheets of irregularly shaped cells in palisading pattern at the periphery. There were large number of cells with vacuolated cytoplasm resembling sebaceous cell in certain part of the tumor cell masses and several keratin pearls.
Diagnosis confirmed by clinical appearance and histological picture. These lesions could be treated sucessfully by wide excision.
