One patient had synchronous triple primary biliary cancers of different histopathologic types: well-differentiated common bile duct (CBD) cancer; poorly differentiated ampulla of Vater cancer; and pancreatic ITPN associated with an invasive carcinoma
. Three patients had metachronous gallbladder (n=2) and CBD (n=1) cancer.
Prognostic factors in T1 bladder urothelial carcinoma: the value of recording millimetric depth of invasion, diameter of invasive carcinoma
, and muscularis mucosa invasion.
One third of cases of invasive carcinoma
are classified into special morphologic type but the majority of breast cancers have no special type of characteristics and are termed invasive ductal carcinoma of no special type, or not otherwise specified (NOS/NST).
A limited sample obtained from CNB (mostly 3-5 specimens per biopsy) may result in 'histologic underestimation', as 20%-56% of ADH lesions diagnosed at CNB contain foci of cancer at subsequent surgery excision, and among lesions previously diagnosed as DCIS, 16%-35% contain invasive carcinoma
Histological findings classify HCC into minimally or widely invasive carcinoma
. Tumors with capsular or vascular invasion <4 foci represent the minimally invasive variant of HCC, while extensive vascular invasion >4 foci and extra- thyroidal extension represent the widely invasive variant.
Neurosecretory granules in small cell invasive carcinoma
of the urinary bladder.
(10) This approach is commonly employed by surgeons in the treatment of ductal carcinoma in situ of the breast which, like CAH, is a stage 0 cancer that can be associated with invasive carcinoma
on final pathology.
It covers sampling and preparation technique, fixation, and staining; principles of interpretation; the normal breast; the cytology of inflammatory and reactive changes; the epidemiology, histological features, and cytology of cystic, epithelial proliferative, and fibroepithelial lesions, invasive carcinoma
, and other breast neoplasms; assessment of the lymph node status; and ancillary techniques.
SC shows a biphasic histologic appearance with epithelial changes varying from dysplasia to invasive carcinoma
and stromal component composed of fusiform or spindle-shaped cells [2-4].

Two women with occult invasive carcinoma
had not undergone sentinel lymph node biopsy during prophylactic mastectomy and were managed with both axillary ultrasound and close follow-up.
Focally, these tumors can transform into invasive carcinoma
; hence, early diagnosis and treatment is crucial .
