Metastatic clear renal cell carcinoma could be considered, given the low-grade appearance with clear cells and histiocyte-like cells observed in MASC.
Additionally, CD10 and PAX8 immunostains on cell block material would help to resolve the differential diagnosis.
Mammary analogue secretory carcinoma may also express GATA3, pancytokeratin, CK7, CK8, CK18, CK19, epithelial membrane antigen, vimentin, MUC1, MUC4, STAT5a, GCDFP15, and adipophilin, (3,17) but these are typically not used clinically in the diagnosis of MASC. Mammary analogue secretory carcinoma is typically negative for high-molecular weight keratin and basal cell/myoepithelial markers, such as calponin, SMA, CK14, CK5/6, and p63.
(19) In the context of salivary gland neoplasia, this translocation is specific for MASC. (3,7,8) However, several other non-salivary gland neoplasms harbor this rearrangement, including secretory carcinoma of breast, infantile fibrosarcoma, congenital mesoblastic nephroma, and some cases of acute myeloid leukemia.
As result of the DFSA's finding, certain other requirements followed, which had not been fulfilled by MASC.
I call these four options (carsharing, ridesharing, rental and taxis) along with informal carsharing between friends, neighbors, etc., Metered Access to a Shared Car or MASC.
I juxtapose it with what I call One-Person, One-Car Orientation or OPOCO.
Phase 4 occurred after the participants had completed a 4-week, eight-session SST intervention; the assessments again included the WCST, CT, and the MASC.
Because the data presented here were part of a parent study on work-related SST, our SST intervention focused on work-related social skills such as starting, joining, and ending conversations with coworkers; asking for information; asking for feedback about job performance; and responding to criticism.
