The present case comprises both components intermingled with each other, indicating that sesmoplastic tumor was a true hybrid lesion rather than a collision lesion. Desmoplastic ameloblastoma Rastogi, R. Many surgeons prefer a radical surgical approach in the form of resection as management of all types of ameloblastoma as it is a formidable tumor due to its local aggressive nature and its tendency to recur [ 2425 ].

Formation of metaplastic bone trabeculae osteoplasia rimmed by active osteoblasts has been described in a few cases.

Immunohistochemically, expressions of extracellular matrix proteins, tenascin, fibronectin, and type I collagen, in a hybrid ameloblastoma lesion, have been reported suggesting that these extracellular matrix proteins participate in tumoral modulation in hybrid lesions [ 15 ].

In ameliblastoma series by Reichart et al. The DA usually appears in the anterior and premolar regions as a mixed radiolucent and radiopaque lesion sometimes mimicking a benign fibro-osseous lesion. Histologically, it is characterized with extensive stromal collagenisation or desmoplasia with small nests and strands of odontogenic epithelium Fig.

Un raro caso clinico] Cristofaro, M. We therefore chose enucleation and curettage and opted for preservation of the inferior alveolar nerve despite understanding the increased risk of tumor recurrence. Discussion Clinically, DA may develop in all ages, however, people of the 4th and 5th decade are more prone to be affected. amelobastoma

Open in a separate window. Desmoplastic ameloblastoma DA is one of the 6 histopathological subtypes of ameloblastoma. Radiologically, the desmoplastic variant exhibits atypical and varied radiographic features such as: During desmoplasitc clinical examination, a firm swelling of the right mandibular alveolar ridge, which desmoplastid from the lateral incisor to the second premolar, was observed Figure 1. Type I collagen showed intense staining in a fibrillar pattern in DA areas reflecting its high grade in the matrix.

The extracellular matrix has an important role in the behavior of neoplastic cells and immunohistochemical studies on the expression of tenascin and fibronectin proteins and Type I collagen in hybrid lesions have also been reported.
