Abstract
|
|
|
Mixed tumor can be defined as arising from the skin, often from sweat glands, and as being composed of epithelial elements intermingled with cartilage or myxoid tissue in such a way that epithelial cells appear to be continuous with these other types of cells without separation by a basement membrane.
Recently, we had opportunity to observe a patient, 34-year-old woman, who had typical mixed tumor of the skin in the central portion of the chin. The tumor developed as a solitary, firm, rice-sized subcutaneous nodule which had been present for 6 months with little increase in size and without any pain and tenderness. The covering skin was normal except mild erythema. Clinically, the lesion was similar to sebaceous cyst. Under local anesthesia, the whole tumor mass was removed
7 surgically for histologic study.
The histopathologic finding reveals nests of cuboidal or polygonal cells, tubuloalveolar and ductal structures, and homogeneous, faintly bluish chondroid or foamy appearing matrix. (Photo. 1, 2, 3 & 4)
