A wide variety of lesions occur in maxilla. timely intervention of many of these lesions. Among 37 cases of non malignant lesions of maxilla received at our institute during last H 89 dihydrochloride supplier 2?years, we report two cases of giant cell reparative granuloma, two cases of fibrous dysplasia, one case of pigmented melanotic neuroectodermal tumor and one case of solitary myofibroma, for their rarity and overlapping features of these lesions clinically and radiologically. Materials and Methods Of 37 cases (Table?1) of benign lesions of maxilla received in 2?years between 1st February 2010 and 31st January 2012 in our institute, we report six uncommon and interesting lesions of maxilla.

The bloating was diffuse, extending and non-tender into ideal nose wall structure. CT scan of paranasal sinuses demonstrated large well described smooth tissue denseness lesion with central necrosis in the proper maxilla with erosion of anterior and medial wall space of maxillary sinus and alveolar procedure. No tooth or calcification noted in the lesion. Ground cup opacities involving correct zigomatic bone tissue, correct mandible, occipital, frontal and correct parietal bone fragments were observed. Best maxillectomy along with lesion in the proper zygomatic bone tissue and frontal bone tissue was done. Open up in another windowpane Fig.?1 ? Case-2: (Fig.?1b, c) A 26?year woman presented with repeated swelling in correct hemi-face since last 8? weeks leading to proptosis. CT scan demonstrated a hyperdense heterogeneous expansive mass of unequal contour concerning ethmoid, correct maxillary correct and bone tissue orbit. Biopsy was extracted from the maxillary bone tissue. Case-3: (Fig.?2a) A 40?year female came with repeated unpleasant swelling of remaining face since 4?weeks. CT scan demonstrated a smooth tissue denseness lesion involving remaining maxillary antrum with erosion of H 89 dihydrochloride supplier lateral wall structure from the maxillary sinus and the ground of remaining orbit. Tumor demonstrated extension in to the smooth tissue from the cheek, extraconal and intra-orbital fat. Biopsy was delivered from maxillary sinus. Open up in another windowpane Fig.?2 ? Case-4: (Fig.?2b) A 26?year man offered a repeated lesion in remaining face since 1?yr. CT scan exposed an irregular smooth tissue H 89 dihydrochloride supplier shadow concerning remaining maxillary antrum with designated development of maxilla H 89 dihydrochloride supplier anteriorly. Inferiorly, development of alveolar margins concerning hard palate had been seen, with thinned out bony and cortex trabeculations traversing H 89 dihydrochloride supplier the mass. Case-5: (Fig.?3a, b) A son of 12?years offered infraorbital inflammation in the still left maxillary area. The bloating was observed as 1?cm mass at age 8?weeks and was slow developing. Since last 1?yr, the inflammation was developing rapidly, reached present size of 8??7?cm. Boy issues of problems in eating and phonation. CT scan of paranasal sinuses showed expansile lesion of left maxillary bone with altered attenuated and thickened left nasal plate. Un-erupted teeth were present within the lesion. Hemi-maxillectomy was done and entire lesion was removed and reconstruction surgery was done. Open in a separate window Fig.?3 ? Case-6: (Fig.?4a) A 13?yr girl presented with swelling involving left maxillary region since 8?months gradually increasing in size. CT scan revealed an expansile lytic lesion involving alveolar process of maxilla with partial erosion of upper medial canine tooth. The lesion was expanding into antrum with remodeling of floor and medial wall of left maxillary sinus. Internal areas of calcification noted. No evidence of internal septations. Open in a separate window Fig.?4 ? Results Case-1 and -2: (Fig.?1d) Biopsy from maxilla showed disorganized bone surrounded by immature fibrous tissue. The bony trabeculae lack osteoblastic rimming. These irregular, misshapen trabeculae formed odd geometric patterns. Case-1 is diagnosed as polyostotic fibrous dysplasia in co-ordination with clinical data, and case-2 was diagnosed as monostotic fibrous dysplasia. Case-3 and -4: (Fig.?2c) Biopsy from maxilla showed fibrovascular connective tissue stroma composed of proliferating plump fibroblasts along with osteoclastic giant cells, hemosiderin laden macrophages, foci and hemorrhage of osteoid. Both -4 and case-3 were diagnosed as huge cell Rabbit Polyclonal to Tau (phospho-Ser516/199) reparative granuloma. Case-5: (Fig.?3c) Sections through the soft cells and decalcified areas showed huge cells containing deep brownish pigment and little blue circular cells forming rosettes and little clusters. Melanin bleach was completed to demonstrate how the brownish pigment in bigger cells can be melanin. HMG45 was positive in melanin including cells. Synaptophysin and GFAP was positive in little cells focally, neuron particular enolase was positive in both little and pigmented cells. These features are in keeping with melanotic neuroectodermal tumor of infancy. Case-6: (Fig.?4b) Pathologic evaluation from the excised specimen revealed primitive fibroblastic cell proliferation.
