Characteristics and clinical outcomes of pleomorphic lobular carcinoma in situ of the breast BREAST JOURNAL Fasola, C. E., Chen, J., Jensen, K. C., Allison, K. H., Horst, K. C. 2018; 24 (1): 66–69

Abstract

Pleomorphic lobular carcinoma in situ (PLCIS) of the breast is a rare variant of lobular carcinoma in situ (LCIS). We reviewed 78 cases of PLCIS diagnosed at our institution from 1998 to 2012. Among all cases, 47 (60%) were associated with invasive carcinoma and/or ductal carcinoma in situ (DCIS) after final surgical excision. Of the 20 cases with PLCIS alone on core needle biopsy (CNB), 6 (30%) were upgraded to invasive carcinoma or DCIS after final surgical excision. Our findings support a recommendation for complete surgical excision of PLCIS when diagnosed on CNB.
