“…In addition to the conventional mammographic features, CESM revealed more details of the lesion. Subtracted images showed that the cyst had peripheral rim enhancement, which has been previously shown on MRI, 2 , 10 , 20 and part of the cyst wall was thickened, which was consistent with the CT findings. The intensity in the cyst was low compared with the background enhancement, revealing the cystic nature of the lesion.…”

Giant epidermal inclusion cyst with infection arising within the breast parenchyma: a case report

et al. 2021

Epidermal inclusion cysts (EICs) of the breast develop in the deep breast parenchyma, and they are very rare. Only about 10 cases have been reported in the English-language literature to date. In this report, we present a rare case of a giant EIC with infection arising within the deep breast parenchyma. Unlike a typical EIC of the breast, the EIC in the present case was a cystic and solid lesion containing a large amount of liquid within the cyst and popcorn-like calcification in the wall. In this report, we describe the contrast-enhanced spectral mammography (CESM), ultrasonography, and computed tomography findings and provide a reference for the diagnosis of EICs. To the best of our knowledge, this is the first report of the CESM findings of an EIC. Our case illustrates that CESM has excellent performance similar to that of magnetic resonance imaging and is much more effective than conventional digital mammography. Additionally, our case indicates that precise correlation of CESM with ultrasonography findings contributes to the diagnosis of EICs. This rare case with multiple imaging findings will increase the awareness of EICs in the breast parenchyma.

“…Paliotta et al identified a total of 91 patients affected by epidermal inclusion cysts of the breast through a search of the literature in 2014 [2], and thereafter, sporadic case reports of epidermal inclusion cysts have been published until recently [7,9–15]. 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.…”

“…Mammographic presentation of epithelial inclusion cysts of the breast usually includes a circumscribed iso- or hyperdense mass [2,21] and can sometimes be accompanied by microcalcifications [21]. Magnetic resonance imaging features were reported in a few cases, which were circumscribed masses with a fluid-like signal of a variable low-signal component on T2-weighted images and peripheral rim enhancement [2,5,6,9] or no enhancement [22] on contrast-enhanced images.…”

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.

“…Epidermal inclusion cysts are commonly found on the scalp, face, neck, trunk, and extremities and typically present with classic dermal findings of an erythematous papule with a central punctum [1][2][3][4]. Based on a literature review from 2015 by Paliotta et al, 82 cases of epidermal inclusion cyst in the breast were reviewed and a total of 90 cases have been reported in the international literature.…”

“…Based on a literature review from 2015 by Paliotta et al, 82 cases of epidermal inclusion cyst in the breast were reviewed and a total of 90 cases have been reported in the international literature. Causes of epidermal inclusions cysts include congenital factors, obstruction of a hair follicle, epidermal fragment implantation into the dermis secondary to damage to the epidermis, or in the case of fibrocystic disease development of squamous metaplasia of columnar cells within a dilated duct [1][2][3][4].…”

Giant Epidermal Cyst Mimicking Aggressive Fibromatosis of the Breast

Fibromatosis of the breast represents <0.02% of all breast tumors. Typically, fibromatosis is non-metastasizing but locally aggressive and is treated with surgical excision. We report a case of a nonagenarian requiring mastectomy for an epidermal inclusion cyst that diagnostically mimicked fibromatosis of the breast. She underwent diagnostic breast imaging for a period of almost two years to monitor the size of her breast tumor. However, in a six-month timeframe, her mass dramatically increased in size and was becoming symptomatic to the patient. The rapidly growing tumor was concerning for occult breast malignancy.
