Microinvasion is more common with the comedo subtype of DCIS (53% microinvasion), multicentric DCIS and DCIS presenting with a palpable mass or large size on imaging.
A recently recognized subtype of LCIS, the pleomorphic subtype of LCIS--in contrast to the more common classic LCIS subtype--consists of large atypical epithelial cells with frequent mitoses, foci of central necrosis, and prominent microcalcifications, all well-described characteristics of the comedo subtype of DCIS.
Segmental clustered pleomorphic Invasive ductal carcinoma-- and punctate calcifications (no comedo type mass)--calcifi-cation pattern malignant 18.
12-Week Reduction in Median Comedo Lesion Count Duac and Tazarotene 70% Tazarotene Alone 60% Note: Based on a study of 121 patients.
Li and colleagues also found a sixfold increase in a less aggressive form of ductal carcinoma in situ, a condition called noncomedo DCIS, while incidence rates of a potentially more aggressive type, called comedo DCIS, have declined during the last five years.
Microscopically, the tumor cells were arranged as infiltrative ducts with comedo necrosis in a background of desmoplastic stroma (Figure 3, B).
1) The necrosis was defined as either (1) a punctate type, when a collection of nuclear fragments was present focally within the LCIS; or (2) a comedo type, when prominent plugs of necrotic material were present in the lumen of the glandular spaces distended by LCIS.
Fortunately, from a diagnostic perspective, apocrine DCIS is more frequently a high-grade lesion, in which case malignant features such as comedo necrosis, tumefactive growth, and overtly atypical cytologic features are readily appreciated.
The subset analysis showed that the only independent predictor of ipsilateral breast tumor risk during follow-up was comedo necrosis; nonirradiated patients with moderate to marked comedo necrosis had a far greater risk than those with slight to no comedo necrosis (Cancer 86[3]:429-38, 1999).
The purpose of this study was to use cases from Howard University Hospital (HUH) to prove that sentinel lymph node biopsy (SLNB) should be the standard for determining the regional nodal status in patients with clinical stage 0 (florid cancer in situ or the comedo type), stage I, and stage 11 breast cancer and to look into factors that may affect the accuracy of using SLNB in staging, such as patient's age, physician experience, technique used in performing SLNB, location of tumor, and procedure performed before SLNB.
Many of the involved seminiferous tubules showed central necrosis that resembled mammary ductal carcinoma, comedo type (Figure 3).
A 35-year-old woman with a palpable mass in the right breast underwent a lumpectomy that showed a microinvasive carcinoma amid ductal carcinoma in situ of the comedo type.
