Clinical featuresThis section has been translated automatically.
1.0-2.0 cm in size, slowly developing over a period of 1-2 years, mostly surface-smooth, painless (a slight sensitivity to pressure may be present) solid plaques or flat protuberant nodules. Clinically the tumours are classified as dermatofibromas or scar keloids.
HistologyThis section has been translated automatically.
In the middle and deep dermis, spreading to the subcutis, there are moderately sharply defined, solid, CEA- and pancytokeratin positive, and S 100 and cytokeratin 20 negative tumor aggregates which are characterized by tubular strands embedded in a fibrillar stroma when magnified. The epithelial proliferates are characterized by small and larger holes, which cause the sieve-like (cribriform) aspect. The lumina are optically empty. Individual tubules are lined by cubic or cylindrical cells. Occasional mitoses.
Differential diagnosisThis section has been translated automatically.
adenoid basal cell carcinoma, metastasis of a breast carcinoma (atypical localization, lack of expression of estrogen or progesterone receptors), metastases of visceral carcinomas, primary cutaneous adenoid-cystic carcinoma (pronounced infiltrative growth with perineural infiltration)
