Immunohistochemistry can be useful to identify or delineate subtle melanocytic proliferations such as desmoplastic
melanoma, lentigo maligna, and subtle invasion in areas of fibrosis or inflammation underlying melanoma in situ.
On CT scan, a carcinoid tumor affecting the mesentery appears as a soft tissue mass with calcification and desmoplastic
stranding, which produces a "sunburst" appearance.
PDL1 expression in desmoplastic
melanoma is associated with tumor aggressiveness and progression.
With microcystic adnexal carcinoma it is difficult to differentiate from infiltrating basal cell carcinoma and desmoplastic
It came after she was diagnosed in 2011 with desmoplastic
small round cell tumour, or DSRCT, having endured terrible back pain while on holiday.
As far as we know only 37 cases were previously described in the literature under different names like: desmoplastic
nested spindle cell tumor of the liver, ossifying malignant mixed epithelial and stromal tumor of the liver , nested stromal epithelial tumor of the liver and ossifying stromal-epithelial tumor , It was first described by Ishak et al.
Caption: Figure 4: A neoplasm with an infiltration pattern is identified in small- and medium-sized nodules, surrounded by desmoplastic
melanoma (DM) represents a relatively rare variant of cutaneous melanoma with a clinical course more similar to soft-tissue sarcoma .
small round cell tumor (DSRCT) is a rare cancer which predominantly affects males averaging 21 years of age at the time of diagnosis .
Oral manifestations of TS occur in 11% of affected subjects, and oral abnormalities include the presence of delayed eruption, bifid uvula, enamel hypoplasia, cystic hyperostosis, hyperplasia, enamel pitting, haemangioma, multiple osteomas, cleft lip and palate, and desmoplastic
fibromas (DF) [2, 4].
Wide nests of tumor cells can be seen invading as well as a desmoplastic
reaction to the nests and the lymphoplasmacytic host response.
