Patient Data

Age: 50 years
Gender: Female

There is a well-defined lesion at 12 o'clock; measuring about 20 x 18 x 18 mm. The lesion is in subcutaneous plane abutting skin with the presence of a tiny tract from the lesion to the skin. The lesion is heterogeneous with mobile echoes without calcification. Small lobulations and posterior acoustic enhancement are present. It is mildly compressible. There is a thin capsule around the lesion which shows focal breach. There is no intralesional flow. However, there is increased perilesional flow along with perilesional echogenic fat.         

Rest of the breast shows prominently fatty breast parenchyma.

Case Discussion

A female presented with breast pain, swelling for the last few days. Ultrasound shows a lesion with punctum ( track from the lesion to the skin ) favoring epidermal inclusion cyst. Breach in the lesion capsule with surrounding inflammation favor leak from the cyst.

Surgical excision of the lesion showed leak from the cyst. Histopathology diagnosis was an epidermal inclusion cyst.
