How is LCIS diagnosed?

Diagnosis of LCIS Most often, LCIS is found when a breast biopsy is done for another problem that’s nearby. (During a biopsy, small pieces of breast tissue are removed and checked in the lab.) You can learn more about pathology reports showing LCIS in Understanding Your Pathology Report: Lobular Carcinoma In Situ.

What are the symptoms of lobular carcinoma in situ?

Lobular carcinoma in situ doesn’t have symptoms. It can’t be felt during breast examinations or detected by mammograms. Instead, LCIS is often discovered during tests for other conditions. For example, your healthcare provider might find LCIS while performing a biopsy to evaluate a lump in your breast.

Does LCIS show up on ultrasound?

Traditionally, LCIS does not present as a mass nor does it contain any microcalcifications on radiological imaging, and the mammography and ultrasound findings do not appear to play a role in prospectively diagnosing LCIS [1-3].

What is classic LCIS?

Classic LCIS is a monomorphic, dyshesive proliferation of non-polarized cells with round to oval shape, inconspicuous cytoplasm. The nuclei are located in the center of the cells, and are small, round to oval, with smooth nuclear membrane and inconspicuous nucleoli (Fig. 3).

Does LCIS show up on MRI?

Lobular carcinoma in situ (LCIS) is a nonmalignant, proliferative condition that is a marker for an increased risk of breast malignancy. It is usually indistinguishable from benign parenchyma on MRI.

Does lobular carcinoma cause pain?

Symptoms of Invasive Lobular Carcinoma An area of swelling or fullness. A change to the texture of skin on your breast or nipple, like dimples or an irritated, red, or scaly area. A nipple that turns inward. Pain in your breast or nipple.

Can MRI detect LCIS?

What is florid LCIS?

Florid LCIS (F-LCIS) is an architectural subtype of LCIS that does not express E-cadherin, yet has the histologic and often radiographic appearance of solid-type ductal carcinoma in situ (DCIS).

Does LCIS require surgery?

Overview. Lobular carcinoma in situ (LCIS), also known as lobular neoplasia, is a rare condition in which abnormal cells develop in the milk glands, known as lobules, in the breast. These abnormal cells are not considered to be breast cancer and don’t require any treatment beyond surgical removal.
