(67) Hudson and Collins (67) detected an MYB abnormality in one-half (5 of 10) of the AdCCs, whereas none of the 13 cases of PA showed any MYB abnormality.
Although the diagnosis is fairly straightforward in many cases, at times there is a challenging differential diagnosis between PA and a malignant salivary gland neoplasm, such as adenoid cystic carcinoma (AdCC), polymorphous low-grade adenocarcinoma (PLGA), myoepithelial carcinoma, or epithelial-myoepithelial carcinoma (EMCA).
This novel heterozygous deletion was concerned with a sequence deletion of 5 amino acids (or 15 bp) at the intracellular loop domain (cytoplasmic loop [CL]) of the Cx50 protein (or GJA8 ) [Figure 1]d, which connects two transmembrane domains and was suspected to serving as binding sites of Ca [sup]2+/CaM in gap junction channel function.[sup], Mutations on GJA8 have caused multiplex ADCCs (Cataract 1, multiple types, OMIM#116200) including nuclear cataracts.
The 45 genes selected contain almost all of the genes related to CC.[sup], Moreover, genes related to ADCC, which are interested, were all included.
These include commons SGTs such as mucoepidermoid carcinomas (MEC), adenoid cystic carcinoma (AdCC), and the newly described entity mammary analog secretory carcinoma (MASC).
Moreover, cytological atypia, background mucus, metaplastic epithelial cells (squamous, oncocytic, mucinous, or sebaceous) may mimic low-grade MEC and hyaline stromal globules or a beaded hyaline stroma may give rise to suspicion of well-differentiated AdCC.  In difficult cases, positive immunostaining for intermediate filaments such as GFAP and negative staining of majority of cells for cytokeratin can be helpful.
This paper will outline the origins of the first Australian Anzac Day Commemoration Committee (ADCC) which was founded in Brisbane on 10 January 1916, and trace the persistent efforts of that committee until 1930 when at last legislation was enacted to establish Anzac Day as the unchallenged sacred national day of mourning for the nation' s fallen.
ADCCs use geometric surfaces specially designed from computer models for each power plant, to maximize steam/water contact and channel away noncondensable gases.
(14,15) Recent reports (5,6) have described MYB translocation in a significant proportion of AdCCs. The aim of this study was to determine the incidence of MYB translocations in AdCC by FISH using direct FNA smears and to compare that rate to the incidence in PA, the most common differential diagnosis for AdCC.
In Reply.--We would like to thank Dr Faquin, Dr Pusztaszeri, and colleagues for their work and letter to the editor commenting on our recently published article, Adenoid Cystic Carcinoma Fine-Needle Aspiration Biopsy Using Fluorescence In Situ Hybridization." (1) Pusztaszeri et al (2) reported their results using immunocytochemistry for the MYB protein in direct-aspirate, alcohol-fixed, Papanicolaou-stained smears in adenoid cystic carcinoma (AdCC).
