Granulocytic sarcoma, also called chloroma or myeloblastoma, is an extramedullary invasive tumor composed of neoplastic myeloid cells. In this report, we describe a 43-year-old male patient with a collision tumor composed of an adenocarcinoma and a granulocytic sarcoma in the stomach. The coexistence of a granulocytic sarcoma and adenocarcinoma in the stomach has, to the best of our knowledge, not been reported in the literature. The diagnosis of granulocytic sarcoma is very difficult; especially in the absence of concurrent hematologic disease or in the uncommon setting of coexistence with another tumor. Cautious observation is needed when a finding of unusual atypical cells admixed with an adenocarcinoma in the stomach is confronted.

BACKGROUND
Uncoupling protein 2 (UCP2) is a recently identified mitochondrial inner membrane anion carrier and a negative regulator of reactive oxygen species production. In this study, we evaluated the characteristics and relationships of UCP2 and p53 expression in breast cancer tissues.
METHODS
Tissue microarray slides from 107 cases of invasive ductal carcinoma of the breast were constructed, UCP2 and p53 immunohistochemical staining was conducted, and clinicopathological correlations were investigated.
RESULTS
UCP2 expression in invasive ductal carcinoma was high in 53 cases (49.5%), while p53 expression in invasive ductal carcinoma was high in 37 cases (34.6%). UCP2 expression was correlated significantly with histological grade (p = 0.038) and mitotic count (p = 0.050). UCP2 expression was correlated significantly with p53 expression in invasive ductal carcinoma of the breast (p = 0.045). UCP2 expression (p = 0.8308) and p53 expression (p = 0.3292) showed no significant difference for the overall survival rate in patients with invasive ductal carcinoma.
CONCLUSIONS
UCP2 expression in invasive ductal carcinoma increased proportionally with histological grade and mitotic count. High UCP2 expression in invasive ductal carcinoma was observed in conjunction with high p53 expression.

Abstract PDF

Chondromyxoid fibroma (CMF) is a relatively rare bone tumor that was first described by Jaffe and Lichtenstein in 1948. CMF of the sinonasal tract is very rare. A 28-year-old male presented with long-standing, intermittent, pulsatile pain in the right temporal area. A computed tomography scan showed a 20 x 19 mm round, bony density in the right ethmoid sinus with fluid collection in the ethmoid and frontal sinuses. Additionally, a cystic lesion with surrounding edema was found in the right frontal lobe. The patient underwent a partial ethmoidectomy and frontostomy. A histological examination showed polygonal and stellate cells in a myxoid and chondroid background with a pattern of lobulation and plaque-like calcification. The bone lesion was revealed as a CMF of the ethmoidal sinus, and the frontal lobe cystic lesion was a brain abscess associated with the CMF. We present the case of a CMF of the ethmoid sinus complicated by a brain abscess.
