Microcystic adnexal carcinoma is a rare type of tumor, with about 300 cases reported globally. Due to its similar histology with other tumors, it is occasionally misdiagnosed as desmoplastic trichoepithelioma, basal cell carcinoma, syringoma, and so on. We present a patient with a mass on the perioral area who was preoperatively diagnosed with trichoepithelioma. Microcystic adnexal carcinoma wa...
Desmoplastic small round cell tumor is a rare malignant tumor that occurs primarily in young males. Here, a case of small round cell tumor in an adult male successfully treated with a curative concurrent chemoradiotherapy is presented. A 58-year-old man had an intrapelvic tumor. Surgical resection was attempted, but the tumor was unresectable. Needle biopsy was performed and the diagno...
Perineural invasion in tumors is typically indicative of malignancy. There are exceptions in most organ systems, but interpretation is complicated when the tumor in question also mimics malignancy. An example of this challenge is found in the interpretation of sclerosing epithelial tumors of the skin. The differential diagnosis for this category of tumors includes malignant entities such as inf...
The histologic hallmark distinguishing desmoplastic ameloblastoma (DA) from conventional ameloblastoma (CA) is its pronounced stromal desmoplasia, and this formed the basis of this investigation. To elucidate the stromal characteristics, localization patterns of oxytalan fibers, type III collagen and BMP family in DA (n=8) was compared with CA (n=24), and periodontal ligament (PL) (n= 8). Oxyta...
