AbstractAbstract PDF
High microsatellite instability (MSI-H) colorectal carcinomas (CRCs) with numerous mutations in the microsatellite sequence are characterized by a right-sided preponderance, frequent peritumoral and intratumoral lymphocytic infiltration, and frequent mucin production. However, no study has correlated anatomic site and type of genetic changes with clinicopathologic changes.
We analyzed the histopathologic features of 135 MSI-H CRCs and compared them to 140 microsatellite stable (MSS) CRCs. Histopathologic changes in MSI-H were further analyzed according to anatomic sites and genetic changes.
MSI-H CRCs showed previously reported clinicopathologic findings; a right-sided preponderance, an increased number of mucinous carcinomas, and peritumoral lymphoid reactions (p<0.001 for each variable). Increased serum CEA levels showed an MSS CRC preponderance (p=0.013). We further analyzed the histologic differences between right- and left-sided MSI-H tumors. We found that MSI-H CRCs on both sides had similar clinicopathologic findings, except for higher tumor stage (p=0.048) and less frequent abnormal CEA levels in left-sided MSI-H tumors (p=0.027). We found that not all clinicopathologic features were different between hereditary nonpolyposis colorectal cancers (HNPCCs) and sporadic MSI-H CRCs.
These findings indicate that MSI-H CRCs of the left colon have similar clinicopathologic characteristics as right-sided MSI-H CRCs. We did not find any significant clinicopathological difference between HNPCCs and sporadic MSI-H CRCs.

AbstractAbstract PDF
Chronic sclerosing dacryoadenitis is a rare and under-recognized chronic inflammatory disease of the lacrimal gland. We describe 2 patients with a localized type of chronic sclerosing dacryoadenitis. Both patients presented with a slowly growing painless mass of the eyelid mimicking a tumorous lesion. The morphologic findings of the masses excised under the clinical diagnosis of lymphoma closely recapitulate those of chronic sclerosing sialadenitis (Kuttner tumor). Immunohistochemical staining demonstrated an increased population of IgG4-positive plasma cells confirming that this disease also belongs to the spectrum of a recently described IgG4-related sclerosing disease.

AbstractAbstract PDF
Adenoid cystic carcinoma (ACC) is a rare type of breast carcinoma and this tumor makes up less than 0.1% of all mammary carcinomas; ACC is known to show a relatively favorable prognosis. Among a variety of microscopic growth patterns of mammary ACC, a solid variant is the rarest and this can cause diagnostic difficulties. We present here a case of a solid variant of mammary ACC that occurred in the right breast of a 40-year-old woman who was initially diagnosed with invasive ductal carcinoma. We discuss the histological and clinical characteristics of this case.
