Introduction Solitary plasmocytoma is definitely a rare plasmacytic cell tumor, which occurs in the head and neck region and rarely involves the mandible. 90% plasma cell in the marrow and diagnosis of Multiple Myeloma was confirmed. DISCUSSION SBP is radiographically seen as a well-defined radiolucent expansile lytic lesion with cortical thinning and no periosteal reaction. The imaging appearance of periosteal reaction is determined by the intensity, aggressiveness, and duration of the underlying pathology. Osteosarcoma, Metastasis (especially from sigmoid colon and rectum), Ewing s sarcoma, Haemangioma, meningioma and Tuberculosis are the main differential diagnosis of Sunburst periosteal reaction. Conclusion Sunray periosteal reaction should be included in the differential diagnosis of lytic bone lesion in the mandible. strong class=”kwd-title” Keywords: Plasmocytoma, Sunray, Periosteum 1.?Introduction A Neoplastic proliferation of B cell lymphocyte is called plasma cell neoplasms. They are divided into three types: disseminated, also called multiple myeloma (MM), localized, also called solitary plasmocytoma of bone (SPB) and extramedulary plasmocytoma (EMP).1 Solitary plasmocytoma is a rare plasmacytic cell tumor, which occurs in the head and neck region.2 It rarely involves the mandible.3 Based on radiologic finding, SBP is a well-defined expansile lytic lesion with thinning of overlying cortex and without sclerosis. According to our AUY922 biological activity best knowledge, there have been no reports on the periosteal reaction in AUY922 biological activity SBP. In this case report we present an individual with solitary plasmocytoma of mandible with sunray periosteal response resembling osteosarcoma A distinctive radiologic manifestation. Osteosarcoma, Metastasis (specifically from sigmoid digestive tract and rectum), Ewing’s sarcoma, Haemangioma and hardly ever fibrous dysplasia will be the primary differential analysis of Sunburst periosteal reaction.4 2.?Case presentation A 63-year-old male referred to our hospital due to slowly progressive painful swelling of left mandible of 6-month duration. The symptoms were exacerbated 2?months before admission. Physical examination revealed a left mandibular mass approximately 6?cm in diameter with an osseous consistency covered with a normal skin, without erythema and tenderness. Tongue, lips, buccal, alveolar mucosa and remnant teeth were normal in appearance. His past medical history was unremarkable. He had no previous surgery. His first panoramic radiography of the jaw revealed a lytic lesion in the left mandibular body, 5?mm??4?mm in dimension, ill defined, without marginal sclerosis, causing sunray appearing periosteal reaction (Fig. 1). Open in a separate window Fig. 1 Panoramic X-ray revealed expansile ill-defined lytic lesion in the left hemimandible with sunray periosteal reaction and cortical Rabbit polyclonal to SYK.Syk is a cytoplasmic tyrosine kinase of the SYK family containing two SH2 domains.Plays a central role in the B cell receptor (BCR) response.An upstream activator of the PI3K, PLCgamma2, and Rac/cdc42 pathways in the BCR response. disruption (arrow). The mandibular and skull radiograph showed no evidence of additional radiolucent lesions. Bone marrow aspiration and serum electrophoresis were normal. Laboratory data such as Hemoglobin, Erythrocyte Sedimentation Rate, Blood Urea Nitrogen, Creatinine, Calcium, Phosphorous and Alkaline Phosphatase were within normal limits. A maxillofacial surgeon performed radical excision of left mandibular body with mandibular reconstruction. The patient was discharged 10?days after surgery without surgical complication and started a liquid diet after 12?days of surgery. Histopathology revealed sheets of plasma cells with cartwheel appearance and expansile bony trabecula (Fig. 2A and B) suggestive of solitary plasmocytoma. Open in a separate window Fig. 2 (A) Hematoxiline and eosin staining shows sheets of plasma cells with cartwheel appearance nucleus (arrowhead) and large nucleus in comparison with cytoplasm. (B) Expansile perpendicular bony trabeculae radiating parallel to each other compatible with sun-ray trabeculae (arrow). Complementary treatment was performed by local radiotherapy with a dose of 45?Gy. The patient was asymptomatic for 5?years after treatment. After the treatment was discontinued he developed malaise, weakness and generalized bone pain and further investigation revealed patients anemia (Hemoglobin: 9?g/dl) and thrombocytopenia (Platelet: 67,000). Radiographic AUY922 biological activity Bone survey revealed typical paunch out lesion in the Skull X-ray (Fig. 3). Open in a separate window Fig. 3 Lateral skull X-ray revealed typical (punched out) well defined varying size lytic lesion. Bone marrow aspiration revealed more than 90% plasma cell in the marrow and diagnosis of Multiple Myeloma was confirmed. The patient underwent systemic chemotherapy with malphalan and prednisolone for another 2?years and the disease was controlled. Patient is currently in good health and there is no evidence of disease recurrence. 3.?Discussion SBP (3C10% o.
