• The patient has a BIRADS 2 simple cyst
• To be regarded as a simple cyst, a breast nodule must meet three criteria:
  • The margins must be circumscribed:
    • i.e., a margin “that is well defined or sharp, with an abrupt transition between the lesion and surrounding tissue”
  • It must be anechoic:
    • i.e., “without internal echoes”
  • It must show posterior acoustical enhancement:
    • i.e., “a column that is more echogenic deep to the mass”
• Simple cysts:
  • Are almost never associated with cancer in the absence of other abnormalities seen on mammogram or ultrasound
• There are numerous reflectors in breast tissue, and all of the sound waves that are reflected do not make it back to the transducer:
  • Many of them bounce back and forth (reverberate) between reflectors in the tissue, and with each reverberation, part of the echoes return to the transducer, are recorded, and part undergo another excursion between the reflectors
  • Most of these echoes are obscured by all of the other echoes in the tissue, but when an otherwise anechoic window (a cyst) is present:
    • The reverberation echoes can be seen in the anterior part of the cyst:
      • In the image shown, a hyperechoic band can be seen within or just above the anterior wall of the cyst, especially on the left side of the image:
        • The acoustic mismatches between this band and the less echogenic tissue superficial to it and the anechoic fluid deep to it, cause echoes that reverberate, creating the artifact in the near field of the cyst

Any palpable abnormality in a pregnant or postpartum woman persisting for more than a few weeks needs a careful investigative workup to rule out PABC.

Although up to 90% of PABC presents as a palpable mass, there can be atypical presentations, including milk rejection from the affected breast or bloody nipple discharge.

Bloody nipple discharge can be especially difficult to differentiate from a benign or malignant origin as it may happen due to pregnancy-induced changes leading to delicate intraductal epithelial spurs that are easily traumatized and shed and thus not considered pathologic in all cases.

In the absence of clinically detectable masses or abnormality on cytology, these patients may be followed closely.

However, if bloody nipple discharge persists after several months postpartum, diagnostic studies should be performed to rule out pathology.

Patients with PABC are often found to have advanced disease at diagnosis, with the median size of tumor ranging from 3.4 to 4 cm and the reported incidence of axillary lymph node metastasis between 56% and 73%.

Delay in diagnosis is often due to the physiologic changes that occur in breasts during pregnancy that can pose challenges for differentiating a new mass from engorged and nodular breast tissue on a physical examination.

In the first and second trimesters, there is active proliferation and differentiation of the lobules, alveoli, and lactiferous ducts, leading to enlargement and increased overall density of breast tissue.

The prolactin level rises during the third trimester, which stimulates milk-producing cells to differentiate, and alveoli and milk ducts are filled with colostrum.

Around parturition, the breasts undergo lactogenesis, which leads to the secretion of colostrum and then milk.

PABC shares histology and some prognostic features with breast cancer occurring in other young women.

Invasive ductal carcinoma is the most common histologic subtype, followed by invasive lobular carcinoma.

The majority of tumors are grade II or III, and lymphovascular invasion is common.

However, the molecular subtypes of PABC seem to differ from those of non-PABC.

Several case-control studies have demonstrated that the hormone receptor status in PABC is more likely to be negative when compared with that in breast cancer in age-matched cohorts.

In contrast, there are conflicting reports of the HER-2 receptor status for PABC.

In a case-control study published in 1993 by Elledge and colleagues, 58% of the tumors from pregnant patients were positive for HER-2 on immunohistochemistry, whereas only 16% of age-matched non-pregnant patients had HER-2-positive tumors.

However, in a more contemporary report from the MD Anderson Cancer Center series of pregnant women by Middleton and colleagues, 28% of PABC cases had positive membrane staining for HER-2, and there was no significant difference when compared with breast carcinoma in young nonpregnant women.

Pregnancy-associated breast cancer (PABC) is defined as breast cancer diagnosed during pregnancy or in the first postpartum year.

Breast cancer is the second most common malignancy affecting pregnant women.

It is estimated that one in 3,000 pregnant women is diagnosed with breast cancer and that up to 3% of all breast cancers are associated with pregnancy.

In general, breast cancer in young women is rare; the estimated incidence of breast cancer in women younger than 40 years of age was less than 4% in 2015 in the United States.

However, by definition, PABC occurs in women of reproductive age, and the average age of women with PABC is between 32 and 38 years of age.

The birth rate for women age 30 to 44 years has been steadily increasing in the past few decades, and as more women are delaying childbearing for various reasons, the incidence of PABC has risen and is expected to continue to rise.

As in non-PABC, the risk of PABC seems to be age related.

A large Canadian population cohort study using birth data from a national registry reported that PABC appeared to be more common among women with a first-term pregnancy occurring after the age of 35.

Peritoneal washing cytology (CY)+ in Pancreatic ductal adenocarcinoma (PDAC) is classified as M1 disease by the American Joint Committee on Cancer staging system and NCCN guidelines, whereas the Japanese General Rules for Pancreatic Cancer have not yet included the CY status for staging.

Hiroyoshi Tsuchida et al analysed well-maintained, nationwide database of 1970 patients with PDAC to evaluate the relationship among CY status, clinical factors, and overall survival and to clarify the clinical implications for operative resection in patients who are CY+ status.

It demonstrated that OS in patients who underwent resection was markedly worse in patients who were CY+ than in patients who were CY– who underwent resection and that peritoneal recurrence appeared earlier in patients who were CY+.
