Abstract PDF: Fibrin-associated large B-cell lymphoma (FA-LBCL) is an extremely rare subtype of LBCL that consists of microscopic aggregates of atypical large B cells in the background of fibrin. Here, we report the first case of FA-LBCL in Korea. A 57-year-old male presented with a large amount of thrombus in the thoracic aorta during follow-up for graft replacement of the thoracoabdominal aorta 8 years prior. The removed thrombus, measuring 4.3 × 3.1 cm, histologically exhibited eosinophilic fibrinous material with several small clusters of atypical lymphoid cells at the periphery. The atypical cells were positive for CD20 by immunohistochemistry and for Epstein-Barr virus by in situ hybridization. The Ki-67 proliferation rate was 85%. The patient was still alive with no recurrence at the 7-year follow-up after thrombectomy. Although the diagnosis can be very difficult and challenging due to its paucicellular features, pathologists should be aware of FALBCL, which has likely been underestimated in routine evaluations of thrombi.

Background
Patients with resectable colorectal lung oligometastasis (CLOM) demonstrate a heterogeneous oncological outcome. However, the parameters for predicting tumor aggressiveness have not yet been fully investigated in CLOM. This study was performed to determine the prognostic value of histological growth patterns in patients who underwent surgery for CLOM.
Methods
The study included 92 patients who were diagnosed with CLOM among the first resection cases. CLOMs grow according to three histological patterns: aerogenous, pushing, and desmoplastic patterns. The growth patterns were evaluated on archival hematoxylin and eosin–stained tissue sections.
Results
The aerogenous pattern was found in 29.4% (n=27) of patients, the pushing pattern in 34.7% (n=32), the desmoplastic pattern in 6.5% (n=6), and a mix of two growth patterns in 29.4% (n=27). The size of the aerogenous pattern was significantly smaller than that of metastases with other patterns (p=.033). Kaplan-Meier analysis demonstrated that patients showing an aerogenous pattern appeared to have a poorer prognosis, which was calculated from the time of diagnosis of the CLOM (p=.044). The 5-year survival rate from the diagnosis of colorectal cancer tended to be lower in patients with an aerogenous pattern than in those who had a non-aerogenous pattern; however, the difference was marginally significant (p=.051). In the multivariate Cox analysis, the aerogenous pattern appeared as an independent predictor of poor overall survival (hazard ratio, 3.122; 95% confidence interval, 1.196 to 8.145; p=.020).
Conclusions
These results suggest that the growth patterns may play a part as a histology-based prognostic parameter for patients with CLOM.

Abstract PDF

Ectomesenchymal chondromyxoid tumor (ECMT) is a rare tumor, exclusively arising in the anterior tongue. Thirty-eight cases have been reported in the English literature. It usually presents as a sessile protrusion and shows round to spindle cells embedded in myxoid to chondroid stroma. Tumor cells are almost always positive for polyclonal glial fibrillary acidic protein (GFAP). We report our experience in the recent treatment of a case of ECMT, the third case in 3 years. The mass in the anterior tongue revealed characteristic morphologic features of ECMT and the expression of polyclonal GFAP. Although ECMT should be differentiated from other mesenchymal tumors including myoepithelioma, its clinical, morphological, and immunohistochemical features enable its diagnosis, especially when pathologists are aware of it.
