“…Myoepithelial differentiation in cutaneous spiradenoma is often detected immunohistochemically [46,47], but authentic glands with well-developed myoepithelial cells are extremely rare [48,45]. Malignant transformation of spiradenoma has also been reported in the breast [49,50].…”

“…The majority of eccrine spiradenomas involve the trunk and extremities; lesions involving the breast are very rare (4). Of note, malignant changes and systemic metastasis of eccrine spiradenoma of the breast have been reported (2, 3). Malignant changes of an eccrine spiradenoma are extremely rare (2) and they generally arise from long-standing benign eccrine spiradenomas.…”

“…Eccrine spiradenomas typically present as painful, slow-growing, solitary masses on the head or upper trunk, and they usually occur during the fourth or fifth decade of life, and without a predilection for either gender (2). Eccrine spiradenomas in the breast are very rare (2) and little is known about the corresponding radiologic findings. We report here on the case of an eccrine spiradenoma in the breast of a 47-year-old woman and we present the mammography, ultrasound (US) and breast MRI findings.…”

Eccrine Spiradenoma Arising in the Breast Misdiagnosed as an Epidermal Inclusion Cyst

Eccrine spiradenomas are rare, benign, cutaneous tumors that originate in the sweat glands. Eccrine spiradenomas in the breast are very rare and only a few cases have been reported. We report here on the case of a 47-year-old woman with superficial masses in the breast and these masses had gradually increased in size during follow-up. They were confirmed to be an eccrine spiradenoma on pathologic examination. There have been a few reports about the radiologic findings of eccrine spiradenomas of the breast. This is the first case of an eccrine spiradenoma in the breast that was characterized by multiple imaging modalities, including mammography, ultrasonography and MRI. The lesion in our patient was first diagnosed as an epidermal inclusion cyst based on the imaging findings and the mass's superficial location. Although the mammographic and ultrasonographic imaging findings of eccrine spiradenomas and epidermal inclusion cysts are similar, the MRI findings are different between epidermal inclusion cysts and eccrine spiradenomas. Eccrine spiradenomas should be considered in the differential diagnosis of cutaneous and subcutaneous lesions of the breast.

“…33 Spiradenomas of the breast have occasionally been reported. [34][35][36] None of the cases in the breast literature involved the nipple. However, 1 case presented with skin ulceration and contained areas of malignant transformation to spiradenocarcinoma.…”

“…However, 1 case presented with skin ulceration and contained areas of malignant transformation to spiradenocarcinoma. 36 Spiradenomas are characterized by dermal-based nodules of basaloid cells with abundant admixed lymphocytes, surrounding basement membrane material and small sweat duct lumina, all of which are important histopathologic clues to the diagnosis of an eccrine neoplasm.…”

Basaloid carcinoma of the breast (BCB) is a rare, triple-negative aggressive primary breast tumor that can closely mimic cutaneous basal cell carcinoma (BCC), neuroendocrine tumors, adnexal neoplasms, and other primary breast tumors. Accurate diagnosis of this tumor is critical for appropriate clinical management. We add to the literature 2 female patients with BCB presenting with a nipple mass. Histopathologic findings from both patients showed dermal nests and cords of atypical basaloid cells with epidermal involvement, closely resembling cutaneous BCC. A panel of immunohistochemical stains, including the novel use of CK17, is essential for differentiating BCB from mimickers. BCB is a rare primary breast tumor that follows an aggressive clinical course and closely mimics many basaloid neoplasms, including cutaneous BCC clinicopathologically. Increased awareness of BCB among dermatologists and dermatopathologists is critical for accurate diagnosis and patient care.
