Image showing Bloody nipple discharge. This patient had duct papilloma. Nipple discharge is considered clinically significant when it is unilateral and spontaneous. Milky discharge is innocuous and needs no further investigation.

Fibrocystic change: External surface of excised mass.

Fibrocystic change: Excised breast mass showing multiple cysts of varying sizes filled with coagulated greenish fluid. Grey white areas histologically showed sclerosis.

Fibrocystic change: Closer view of cut surface: Excised breast mass showing multiple cysts of varying sizes filled with coagulated greenish fluid. Grey white areas histologically showed sclerosis.

Accessary axillary breast tissue: This is very common. Differentials include lymphadenopathy, lipoma. FNAC may show mature adipose tissue with benign ductal epithelial cells.

Duct Papilloma: Images showing excised irregular breast mass.

Duct Papilloma: Images showing excised breast mass having dilated ducts with polypoidal masses protruding into it.

Breast carcinoma, right breast: Notice the peau d’orange skin and retracted nipple

Breast carcinoma pT4b: show huge right breast mass with ulceration of overlying skin. Notice the dilated veins over the tumor.

Cytology of breast aspirate showing a large pleomorphic tumor cell. Notice the nucleus which is appearing as if it is going to drop off. This feature is highly suggestive of malignancy.

Breast carcinoma, right breast: Notice the dilated veins and retracted nipple.

Breast carcinoma, left breast: Notice the peau d’orange skin and retracted nipple.

Breast carcinoma: Notice the skin ulcers and small nodules due to tumor invasion (pT4b)

Breast carcinoma: Notice the peau d’orange skin and retracted nipple.

Breast carcinoma, right breast: Notice the skin dimpling. Traumatic fat necrosis also produces similar appearance mimicking carcinoma.

Breast carcinoma, right breast: Notice the subtle peau d’orange skin and multiple dots are TruCut biopsy sites.

Breast carcinoma, right breast: Notice the skin retraction.

Breast carcinoma: Cut surface showing grey white tumor with irregular borders

Breast carcinoma, right breast: Notice the nipple retraction. Bleeding is from FNAC site.

Breast carcinoma, left breast: Notice the skin retraction and a satellite nodule (pT4b).

Breast carcinoma, right breast: Notice the the pressure ulcer of skin opposite to the tumor in the breast fold. Smooth and shiny surface of the skin over the tumor indicative of invasion.

Mastectomy specimens from a 60 year old female. Colloid carcinoma of breast: Notice the nodule in the lower outer quadrant.

Mastectomy specimens from a 60 year old female. Colloid carcinoma of breast: Notice the well circumscribed tumor with mucoid cut surface. Because of its well circumscription and free mobility it may be mistaken for fibroadenoma clinically.

Mastectomy specimens from a 60 year old female. Colloid carcinoma of breast: (Closer view of previous case) Notice the well circumscribed tumor with mucoid cut surface. Because of its well circumscription and free mobility it may be mistaken for fibroadenoma clinically.

Paget's disease of nipple: Notice the retracted nipple with rawness imparted to the surface. This patient had underlying ductal carcinoma.

Paget's disease of nipple: Notice the extensive eczematous involvement of the nipple and areolar skin. This patient had underlying ductal carcinoma.

Breast carcinoma: Notice the shiny nodule with increased vascularity.

Benign phyllodes tumor: Huge breast tumor with ulceration of overlying skin and fungation. Because of its huge size and rapid growth it may cause pressure / ischemic necrosis of the skin and it may be mistaken for malignancy.

This patient underwent mastectomy 6 months back for breast carcinoma. Notice the nodule near the scar area. FNAC revealed recurrence.
