“…Epidermal inclusion cysts of the breast typically develop during the fifth decade of life [2], and are usually located in the skin; however, they can develop in unusual locations, such as cutaneously on the nipple or areola or intra-parenchymally in the subor peri-areolar regions. Through a search of the literature, we identified a total of 21 cases where epidermal inclusion cysts developed in these unusual locations; 15 in sub- or peri-areolar region [1,3,5,12,16–19], 4 on the nipple [11,13,14,20], and 2 on the areola [10,11] (Table 1). Furthermore, we found presentations of nipple discharge in a total of 4 cases in the literature; 3 cases in sub- or peri-areolar regions [3,12,16] and 1 case on the nipple [14].…”

Patient: Female, 58 Final Diagnosis: Epidermal inclusion cyst Symptoms: Bloody nipple discharge Medication: — Clinical Procedure: — Specialty: Radiology Objective: Rare disease Background: Epidermal inclusion cysts rarely develop in the breast. The cysts that do develop within the breast typically present as cutaneous or subcutaneous cysts. They more rarely present in a subareolar location or in a ruptured state. Thus far, 5 cases of ruptured epidermal inclusion cysts in subareolar locations have been reported in the English literature. Furthermore, clinical presentation of nipple discharge is rare in epidermal inclusion cysts of the breast; only 4 such cases has been reported. Case Report: A 58-year-old female presented with a 1-month history of bloody discharge from her left nipple. Mammography showed focal asymmetry in the left subareolar region; sonography showed a left subareolar mass with irregular shape, indistinct margin, heterogeneous echogenicity, and posterior enhancement. The mass was surgically excised; a pathological diagnosis of ruptured epidermal inclusion cyst with foreign body reaction and abscess formation was established. In this case, the clinical presentation of bloody nipple discharge was peculiar; furthermore, mammographic and sonographic features were indistinguishable from breast malignancy or typical breast abscess. Conclusions: A ruptured epidermal inclusion cyst can present in an unusual subareolar location, combined with bloody nipple discharge; importantly, this can radiologically resemble breast malignancy.

“…Unusual presentation, especially in anatomic locations where they are not considered may make correct diagnosis difficult. To date, only a few cases of similar lesions have been described involving the nipple [ [7] , [8] , [9] , [10] ]. To the best of our knowledge, this is one of the few, if any, described aggressive cases of an epidermoid cyst located at the areola without involvement of the nipple.…”
