Solitary, painful, slowly growing, pink-gray lesion, often > 1cm. Well circumscribed, round / oval cell nests (blue balls) in dermis or subcutaneous tissue. Small basaloid cells on the outside and larger polygonal cells with vesicular nuclei and prominent nucleoli towards the center Abstract Introduction: Spiradenocarcinomas (SCs) are rare and potentially aggressive skin adnexal tumors. Optimal treatment has not yet been established. Experiences with this carcinoma are mostly presented in case reports and few case series Histology of eccrine spiradenocarcinoma In eccrine spiradenocarcinoma, sections show areas of benign eccrine spiradenoma with an abrupt transition in morphology (figures 1, 2). The malignant areas can be carcinomatous or sarcomatous. The carcinoma typically shows marked nuclear pleomorphism, atypia and mitoses (figures 2, 3) Conclusion: Histologic features that strongly favor atypical spiradenoma or spiradenocarcinoma include abrupt transition to malignant foci, atypical mitotic figures, and monomorphic loss of the dual cell population. Ki-67, p53, and S100 may help delineate areas of atypical or malignant transformation in spiradenomas
Resembles dermal counterpart, with lobules containing biphasic cell population (packed, monotonous, basaloid epithelial cells with scant cytoplasm and round / oval nuclei and peripheral smaller cells with hyperchromatic nuclei . Morphologically, low-grade tumors are thought to behave more favorably. Limited information is available, however, with only 18 published cases on SC with regard to diagnostic procedures, treatment, and outcome. Results: Median patient age was 60 years and sex distribution was balanced. Tumor manifestations were evenly distributed within the sweat gland carrying skin. The most commonly reported symptom was accelerated growth of a longstanding indolent lesion, typically present for more than 2 years. Metastatic spread to the lung, bone. Abstract Spiradenocarcinoma is a rare skin adnexal neoplasm with potential for aggressive behavior, classified histologically into low- and high-grade tumors. Morphologically, low-grade tumors are..
Presents as a slow growing, nodular, solid or cystic cutaneous mass usually measuring up to 3 cm in diameter (Dermatology 2016;232:78) Characterized by variably sized nests and nodules of epithelial cells within the upper or mid dermis, typically with no overlying connection to the epidermis (J Clin Pathol 2007;60:145) Wide local excision is the treatment of choice (J Neurosci Rural Pract 2014. Histologic features that strongly favor atypical spiradenoma or spiradenocarcinoma include abrupt transition to malignant foci, atypical mitotic figures, and monomorphic loss of the dual cell population. Ki‐67, p53, and S100 may help delineate areas of atypical or malignant transformation in spiradenomas. Volume 46, Issue 4 April 201 Hidradenocarcinoma is a rare sweat gland carcinoma, which has been described in a wide age range and at a wide range of anatomic sites. These tumours may behave in an aggressive fashion and wide surgical excision is the treatment of choice Malignant transformation of spiradenoma is a very rare event and its biologic features have not been fully described. Clinically, these tumours are characterized by the rapid enlargement of a long-standing cutaneous nodule Three cases of spiradenocarcinoma and three cases of cylindrocarcinoma showed a salivary gland-type basal cell adenocarcinoma-like pattern, low-grade (BCAC-LG) and/or high grade (BCAC-HG). The remaining three cases of spiradenocarcinoma showed adenocarcinoma in situ, with invasive adenocarcinoma being seen in one of these cases
The embryologic origin of the breast is related to salivary and sweats glands. Thus, breast neoplasms may show differentiation toward these tissues, although this is a rare event in humans. We report the clinicopathologic and immunohistochemical features of a 57-year-old woman presenting with a spir BACKGROUND: Eccrine spiradenocarcinoma is a rare dermal appendage carcinoma believed to arise from transformation of a long-standing benign spiradenoma. This tumor demonstrates highly malignant biologic behavior with a high recurrence rate, frequent lymph node metastases, and overall poor survival

Proliferating trichilemmal cyst and other neoplasms, such as Merkel cell carcinoma, can develop from or within a benign trichilemmal cyst Abstract: Spiradenocarcinoma is a very rare malignant tumor. In situ adenocarcinoma has recently been observed and defined by the preservation of a peripheral myoepithelial cell layer. The pathway for this phenomenon has been hypothesized to involve a sequence of adenomatous changes followed by atypical adenomatous changes, adenocarcinoma in situ, and invasive adenocarcinoma Microscopic (histologic) description. Lobules, nests or cribriform patterns of small basaloid cells with peripheral palisading and a thick basement membrane. Cells have minimal cytoplasm, are moderately pleomorphic with hyperchromatic nuclei and often abrupt transition to squamous epithelium. Single cell necrosis and comedonecrosis are common. Spiradenocarcinoma (also known as malignant spiradenoma and sweat gland carcinoma ex eccrine spiradenoma) was first described by Dabska in 1972, 16 years after Kersting and Helwig originally described its benign precursor.

Malignant spiradenoma is a rare tumor. Malignant tumors of the sweat glands account for approximately 0.005% of all skin tumors. Age at presentation varies from 21 to 92 years. In two thirds of patients, the diagnosis is made after age 50 years, 2 and only 1 pediatric case has been reported. 3 The majority of patients describe a rapid growth of. Malignant sweat gland tumors are rare cutaneous neoplasms, traditionally separated according to their behavior into low- and high-grade malignant. There is significant morphologic overlap, and outright malignant tumors may show relatively bland histologic features. They may, therefore, be mistaken easily for benign neoplasms. Recognition of these tumors and accurate diagnosis is important for. Eccrine carcinoma (EC) is a rare carcinoma that originates from the eccrine sweat glands of the skin and accounts for less than 0.01% of diagnosed cutaneous malignancies.  Sweat gland tumors have traditionally subdivided into four broad groups: eccrine, apocrine, mixed origin (eccrine and apocrine), and other unclassifiable sweat gland tumors
