A female in her 50s who came for screening mammogram A) MLO view mammogram shows grade 1 asymmetric density in right retroareolar region B) Greyscale US image of corresponding region shows cystic lesion.
Fig 2.
A female in her 50s underwent screening mammogram.
A & B) CC and MLO views of breast show grade 2 focal asymmetry in left subareolar region. C & D) Greyscale and Color Doppler ultrasound images of left breast in retroareolar region shows ill-defined hypoechoic lesion without significant vascularity. E) Histopathological evaluation of biopsy specimen showed diffuse dense lymphoplasmacytic inflammatory infiltrates along with macrophage suggestive of subareolar mastitis. HEx200.

A female in her late 50s with pathological right nipple discharge A & B) MLO and CC views of breast show grade 3 retroareolar density with mass like appearance. C & D) Sonography shows a complex cystic mass with solid component E) Biopsy showed a polypoid lesion with branching papillae and dilated ducts. HE x40 F) Back-to-back ducts, are seen all of them showing myoepithelial cells. Foamy macrophages are also seen within the fibrovascular cores. Final diagnosis: Papilloma. HE x200.
Fig 4.
A female in her 40s with left subareolar mass A & B) CC and MLO views of breast show grade 3 retroareolar density in the form of spiculated mass with nipple retraction and adjacent skin thickening. C & D) US shows Irregular hypoechoic subareolar mass with microlobulated margins and nipple retraction. E) Biopsy shows large lobules of tumor cells with solid pattern and few tubules. Small nests, cords and comedo necrosis is noted. Final Diagnosis: Invasive Ductal Carcinoma. HE x 200.
