Wan L, Park A, Khachemoune A. Syringocystadenocarcinoma papilliferum: a systematic review of clinical characteristics, reappraisal of associations, diagnostic pitfalls and management challenges. Arch Dermatol Res 2024; 316:421. [PMID: 38904691 DOI: 10.1007/s00403-024-03176-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/21/2024] [Revised: 05/21/2024] [Accepted: 06/08/2024] [Indexed: 06/22/2024]
Abstract
Syringocystadenocarcinoma papilliferum (SCACP) is a rare and aggressive malignant adnexal tumor originating from apocrine or pluripotent appendageal glands, often associated with a preceding syringocystadenoma papilliferum (SCAP) or nevus sebaceus (NS). This systematic review rigorously examines SCACP through an analysis of 78 cases documented between 1980 and 2024. The study aims to provide a comprehensive review of the clinical manifestations, diagnosis, treatment modalities, and outcomes associated with SCACP, while also reappraising its associations, particularly with NS. SCACP predominantly affects older adults, with an average age of 66.3 years and a slight male predominance, commonly presenting as ulcerated nodules or plaques on the scalp. This review highlights the aggressive nature of SCACP, evidenced by significant rates of metastasis and recurrence. Treatment is primarily surgical, with Mohs micrographic surgery offering potential benefits in terms of margin control and cosmetic outcomes. The association of SCACP with NS is critically evaluated, suggesting a complex etiopathogenesis and underscoring the importance of recognizing this association for timely diagnosis and management. Our review also briefly discusses potential pitfalls faced by clinicians in the diagnosis of SCACP. Our findings emphasize the need for standardized treatment protocols and further research into targeted therapies to improve patient outcomes in SCACP.

Abstract
Eccrine spiradenoma (ES) is an uncommon and benign adnexal tumour originating from sweat glands. The cytological examination of ES poses a diagnostic challenge, as it can be mistaken for various benign and malignant basaloid skin neoplasms. The cytomorphologic features of ES are infrequently documented in existing literature. This study seeks to present a thorough exploration of the cytomorphologic traits associated with ES, accompanied by an analysis of ancillary testing that contribute to the accurate identification of this entity in cytological specimens.Eccrine spiradenoma is infrequently encountered in fine needle aspiration (FNA) cytopathology, and the available literature on its cytomorphologic features is limited. The challenge arises from its similarity to other benign and malignant dermal basaloid neoplasms, emphasizing the critical role of clinicopathologic correlation and immunohistochemical staining in achieving a precise diagnosis.

Abstract
CONTEXT.— Syringocystadenocarcinoma papilliferum (SCACP) is a rare adnexal carcinoma and the malignant counterpart of syringocystadenoma papilliferum (SCAP), which is commonly located on the head and neck and may arise in association with a nevus sebaceus. RAS mutations have been identified in both SCAP and nevus sebaceus. OBJECTIVE.— To evaluate the clinicopathologic and molecular features of SCACPs, which have not been previously explored. DESIGN.— We obtained 11 SCACPs from 6 institutions and reviewed the clinicopathologic features. We also performed molecular profiling using next-generation sequencing. RESULTS.— The cohort comprised 6 women and 5 men with ages ranging from 29 to 96 years (mean, 73.6 years). The neoplasms occurred on the head and neck (n = 8; 73%) and extremities (n = 3; 27%). Three tumors possibly arose in a nevus sebaceus. A total of 4 cases showed at least carcinoma in situ (adenocarcinoma, n = 3; squamous cell carcinoma [SCC], n = 1), and 7 cases were invasive (SCC, n = 5; mixed adenocarcinoma + SCC, n = 2). A total of 8 of 11 cases (73%) had hot spot mutations consisting of HRAS (n = 4), KRAS (n = 1), BRAF (n = 1), TP53 (n = 4), ATM (n = 2), FLT3 (n = 1), CDKN2A (n = 1), and PTEN (n = 1). All 4 cases with HRAS mutations occurred on the head and neck, whereas the KRAS mutation occurred on the extremity. CONCLUSIONS.— RAS-activating mutations were detected in 50% of the cases, of which most (80%) involved HRAS and occurred on the head and neck, which shows overlapping features with SCAP, supporting that a subset may arise as a result of malignant transformation and likely an early oncogenic event.

Abstract
Nevus sebaceus is a hamartomatous lesion characterized by epidermal, follicular, sebaceus, and apocrine gland abnormalities. Approximately 25% of affected individuals may develop benign or malignant secondary neoplasms within the preceding nevus sebaceus. Primary cutaneous apocrine carcinoma (PCAC) is a rare malignant skin tumor affecting elderly adults in their sixth decade of life. Histologically, PCAC appears as a dermal tumor displaying apocrine differentiation with decapitation secretion and malignant features. Secondary malignancy arising from nevus sebaceus is a rare complication, especially for apocrine carcinoma. To date, approximately 200 cases of PCAC have been reported in the literature, and only a few cases have developed PCAC on the scalp. Very few cases (approximately only 12) of PCACs developing in nevus sebaceus have been reported. Here, we report an extremely rare case of the coexistence of PCAC and syringocystadenoma papilliferum arising within nevus sebaceus of the scalp.

Abstract
ABSTRACT Sweat gland carcinoma with neuroendocrine differentiation (SCAND) is a newly proposed tumor entity of primary cutaneous apocrine/eccrine adnexal tumor with neuroendocrine differentiation. The histopathologic variations are not yet well known. In this article, we present a case of SCAND mimicking male breast cancer and syringocystadenocarcinoma papilliferum. A 68-year-old man presented with a reddish 12-mm nodule on his left areola. No lymph node or distant metastases were observed. The patient was disease free 1 year and 9 months after the tumor was surgically resected but died of cerebral hemorrhage. Histopathological examination revealed a predominantly intradermal tumor with marked syringotropism, mimicking a component of mammary ductal carcinoma in situ. In addition, another tissue section displayed a cup-shaped papillated tumor with syringocystadenocarcinoma papilliferum-like features, which were also seen because of marked syringotropism. Diffuse immunoexpression of cytokeratin 7, cytokeratin 19, chromogranin A, synaptophysin, INSM1, estrogen receptor, carcinoembryonic antigen, epithelial membrane antigen, and GATA3 was observed in the tumor, but no BRAF immunoexpression was seen. The present case would help us to understand the histopathological variation and differential diagnosis of SCAND. The histopathological diagnosis of male breast cancer or syringocystadenocarcinoma papilliferum should be made by ruling out SCAND.

Abstract
Syringocystadenocarcinoma papilliferum (SCACP) is a rare malignant neoplasm arising from adnexal tissues and is the malignant complement to the benign neoplasm syringocystadenoma papilliferum (SCAP). SCACP lesions appear as raised nodules or inflammatory plaques and can be associated with SCAP or nevus sebaceous. There have been fewer than 100 described cases of this neoplasm in the literature, and all previously published cases have been described in adults, with the majority occurring in the elderly. We present a case of an adolescent female with a syringocystadenocarcinoma papilliferum arising from a large thigh mass harboring an in-frame alteration in MAP2K1 along with a brief review of the literature.

Abstract
Syringocystadenocarcinoma papilliferum (SCACP), the malignant counterpart of syringocystadenoma papilliferum (SCAP), is an extremely rare malignant adnexal neoplasm. It is described by the World Health Organization as a malignant transformation of SCAP occurring in middle-aged to elderly individuals with a predilection for the head and neck. SCACP seems to arise from a long-standing syringocystadenoma probably on a background of nevus sebaceous (NS) through a multistep progression. A 75-year-old man was referred to our department with a long-standing NS with a recent newly developing nodule on his scalp. The tumor was excised. On histology, the overall architecture of the tumor still resembled an unusual SCAP within NS but simultaneously showed transition to syringocystadenocarcinoma papilliferum in situ and invasive SCACP as recognizable by the presence of areas of nuclear atypia, increased proliferative activity, and infiltrative growth. In summary, we report an extremely rare case of an invasive SCACP of the scalp that demonstrates histological evidence for all transitive steps in the hypothetical multistep progression from NS to invasive SCACP in one single lesion. The implications of these findings are discussed in the light of the relevant literature.

Abstract
Syringocystadenocarcinoma papilliferum (SCACP) is a rare cutaneous adnexal tumor thought to originate from its benign counterpart, syringocystadenoma papilliferum. These tumors are predominantly located on the head and neck with their location on the breast extraordinarily reported; mammary localization poses a great diagnostic dilemma to the practicing pathologist. Herein, we report an unusual case of an 85-year-old woman with an outside diagnosis on a core needle biopsy of metaplastic mammary carcinoma. Upon consultative review of the partial mastectomy specimen, SCACP was identified. Herein, we review SCACP and the diagnostic challenge it poses, especially when localized to the breast. Furthermore, we perform a retrospective review of institutional pathology reports and identified four additional cases of SCACP diagnosed at our institution within the last decade. Finally, we briefly review the literature of SCACP. The entity of SCACP should be well known to pathologists to avoid misdiagnosis.

Abstract
Cutaneous adnexal tumors recapitulate follicular, sweat gland, and/or sebaceous epithelia, and range from benign tumors to aggressive carcinomas. Adnexal tumors can be hallmarks for inherited tumor syndromes. Oncogenic drivers of adnexal neoplasms modulate intracellular pathways including mitogen-activated protein kinase, phosphoinositide-3-kinase, Wnt/β-catenin, Hedgehog, nuclear factor κB, and Hippo intracellular signaling pathways, representing potential therapeutic targets. Malignant progression can be associated with tumor suppressor loss, especially TP53. Molecular alterations drive expression of specific diagnostic markers, such as CDX2 and LEF1 in pilomatricomas/pilomatrical carcinomas, and NUT in poromas/porocarcinomas. In these ways, improved understanding of molecular alterations promises to advance diagnostic, prognostic, and therapeutic possibilities for adnexal tumors.

Abstract
Introduction Au Sénégal, les études portant sur les tumeurs du cuir chevelu sont quasi inexistantes. Notre objectif était de déterminer le profil épidémiologique et anatomo-clinique des tumeurs du cuir chevelu en dermatologie. Méthodes Il s'agit d'une étude prospective, descriptive et analytique, réalisée sur une période de 16 mois (01 mars 2014 au 30 juin 2015), effectuée aux deux services de dermatologie de Dakar. La confirmation diagnostique était histopathologique. Résultats Nous avions colligé 36 patients dont 14 cas de tumeurs malignes et 22 cas de tumeurs bénignes. Le sex ratio était de 1:1, et l'âge moyen de 51 ans pour les premières et 39 ans pour les dernières. La fréquence hospitalière était de 0,18%. Le délai moyen de consultation était de 14 mois pour les tumeurs malignes et 52 mois pour les formes bénignes. Dans 11 cas de tumeurs malignes, le traitement traditionnel était le premier recours. Les tumeurs malignes étaient: carcinome épidermoïde (n=8), carcinome basocellulaire (n=3), lymphome, hidradénocarcinome et dermatofibrosarcome de Darier Ferrand (un cas chacun). Les tumeurs bénignes étaient: botriomycome (n=5), kyste trichilemmal, hamartome sébacé, cylindrome et lipome (2 cas chacun), et chéloide, syringocystadénome papillifère, schwannome, neurofibrome et nævus (un cas chacun). La malignité de la tumeur était associée à l'aspect ulcéro-bourgeonnant (p=0.003), au diamètre >4cm (p=0.05), à la douleur (p=0.009) et au saignement (p=0.006). Conclusion Les tumeurs du cuir chevelu, sur peau noire, sont dominées par les formes bénignes. Le carcinome épidermoïde est la tumeur maligne prédominante.

Abstract
Syringocystadenoma papilliferum (SCAP) is a benign tumor most commonly located on the head and neck area often associated with nevus sebaceus. In its usual location, the human papillomavirus (HPV) DNA and mutations in the RAS/mitogen-activated protein kinase signaling pathway have been detected in SCAP. We studied 16 cases of SCAP in the anogenital areas and buttock where this neoplasm is rare and attempted to find out whether SCAP in these sites have different histopathological and molecular biological features. It seems that there is no significant difference between the morphology of anogenital SCAP and SCAP in other locations. Several tumors in our cohort demonstrated features resembling those seen in warts, but HPV DNA was not found in these lesions. On the contrary, we identified DNA of HPV high-risk types in some tumors without HPV-related morphology. Our study confirms the role of HRAS and BRAF V600 mutations in the pathogenesis of SCAP, including SCAP in the anogenital areas and buttock.

Abstract
We present a case of Syringocystadenocarcinoma papilliferum that originated in the eyelid and extended into the orbit. These tumors are very rare and have the potential to metastasize. A literature review of all the previous cases has been compiled from the Medline, EMBASE, and PubMed databases. We found that the majority of cases present on the head and neck and up to 17% of cases showed metastatic progression. This is the first case to show orbital involvement and highlights the need to remain vigilant with such lesions, as they have a tendency to become aggressive.

Abstract
BACKGROUND Syringocystadenocarcinoma papilliferum (SCACP) is an exceedingly rare cutaneous adnexal neoplasm. We aimed to investigate the clinicopathologic and immunophenotypic features of SCACP, and to discuss the prognosis of this rare entity. METHOD We retrospectively collected clinical, pathological and follow-up data of 10 cases with SCACP. RESULTS There were 8 males and 2 females, with ages ranging from 26 to 74 years. The chest was most frequently involved. Histologically, 1 case only showed SCACP in situ, 9 cases presented with variable invasive components of adenocarcinoma and/or squamous cell carcinoma in addition to areas of in situ. Apocrine differentiation with decapitation was evident in 4 cases and mucinous metaplasia was noted in 1 case. P63 was positive in invasive squamous cell carcinoma, while CK7 was variably positive in invasive adenocarcinoma. Regional lymph node metastasis was confirmed by pathological examination in 4 patients. Follow up was available for 9 patients, ranging from 3 to 112 months. Three patients died of the disease within 1 year after recurrences. CONCLUSIONS Because of high rates of regional lymph node metastasis and mortality in our patients, clinical behavior of SCACP seems to be more aggressive than that previously reported.

Abstract
The authors report 11 cases of extramammary Paget disease (EMPD), all of which also demonstrated a combination of histological changes highly reminiscent of syringocystadenocarcinoma papilliferum in situ. In addition to the classical features of EMPD, characterized by the intraepidermal spread of individually dispersed neoplastic cells with ample cytoplasm, many of which contained mucin, there were areas of acanthosis with the substitution of spinous layer keratinocytes by neoplastic cells, whereas the native basal cell layer was intact. In addition to acanthosis (and sometimes papillomatosis), the dermal papillae showed a prominent infiltrate of plasma cells, completing the resemblance to syringocystadenocarcinoma papilliferum in situ; this similarity was further enhanced in 2 cases, which showed conspicuous gland formation. One additional case showed multifocal dermal proliferations compatible with eccrine syringofibroadenoma (syringofibroadenomatous hyperplasia). The changes described herein seem to be relatively rare in EMPD, and they can represent a diagnostic pitfall, as evidenced by 2 cases that were originally misinterpreted as syringocystadenocarcinoma papilliferum in situ. Clinically, these microscopic changes sometimes corresponded to nodular lesions, which were specifically noted to have a papillated erosive surface.

Abstract
Syringocystadenocarcinoma papilliferum (SCACP) is an extremely rare adnexal neoplasm, believed to arise in a preexisting nevus sebaceus of Jadassohn (NSJ) through a multistep progression process. This hypothetical process involves an NSJ giving rise to syringocystadenoma papilliferum, which then presumably undergoes malignant transformation in rare circumstances to give rise to SCACP in situ, which finally progresses to an invasive SCACP. Of the 30 SCACP cases reported so far, none have documented the process from a birthmark to the final invasive lesion, with histological evidence of each step, in a single tumor. Here, the authors report just such a case. A 74-year-old man presented with a recently enlarging birthmark on the scalp. Excisional biopsy showed an invasive SCACP, in the background of SCACP in situ, syringocystadenoma papilliferum, and NSJ. Furthermore, this tumor showed a concurrent pigmented trichoblastoma and histological evidence of lymphovascular invasion, events that have not been documented with SCACP. Interestingly, all these component lesions were present on a single histological section of this solitary tumor. Regional lymph node metastasis, a rare occurrence in SCACP, was also present in this remarkable case. The authors discuss the implications of these findings in light of the review of relevant literature.

Abstract
Syringocystadenocarcinoma papilliferum (SCACP) is a very rare cutaneous adnexal neoplasm. SCACP presents histologic variability, and it is difficult to establish the diagnosis from a punch biopsy. SCACP has an overall configuration similar to that of syringocystadenoma papilliferum (SCAP). When we diagnose SCACP, the histologic features of SCAP can be contributing and immunohistochemical staining is useful. Our case shows the histologic variability of SCACP and the pitfalls of a punch biopsy for the diagnosis of SCACP.

Abstract
Syringocystadenocarcinoma papilliferum (SCACP) is an extremely rare cutaneous neoplasm with apocrine differentiation. Only 27 cases have been reported up-to-date, 8 of them described as carcinomas in situ. Two cases with local recurrence and 3 cases with regional lymph node metastases have been documented. The authors present the case of a 32-year-old female with a SCACP in situ on the scalp that recurred 8 years after the excision of the primary tumor. No SCACP with late recurrence have been previously reported. This case highlights the need for a long-term follow-up in patients with this type of carcinoma.

Abstract
We report a new case of p63/cytokeratin 7 (CK7) positive syringocystadenocarcinoma papilliferum (SCACP), on the shoulder of an 88-year-old man, with superficial dermal infiltration and squamoid differentiation. We describe the 24th case of SCACP, the malignant counterpart of syringocystadenoma papilliferum (SCAP). At the present, we do not know whether SCACP arises from eccrine or apocrine glands because of the contrasting opinions in the literature. Only few histochemical and ultrastructural studies have previously advised that SCACP could arise from pluripotent stem cells. Through our case, we wish to suggest the stem cell-like properties of the syringocystadenocarcinoma papilliferum. This rare neoplasm shows two different patterns of stem cell marker expression in the glandular and squamous components, respectively. For the double phenotype of SCACP, we propose it like an intriguing model to study histogenesis and stem cell properties for more wide-ranging epithelial tumors.

Abstract
Syringocystadenocarcinoma papilliferum (SCACP) is an exceedingly rare cutaneous adnexal neoplasm, which is typically located in the head and neck, and perianal area. Very few cases have been reported in the literature. Here, we report a case of SCACP with evident transition to squamous differentiation. A 75-year-old white woman presented with 1-year history of a solitary tender nodule in the left upper arm. Physical examination revealed a single, 1.5 × 1.1-cm, erythematous ulcerated nodule within a background of red patch. Biopsy showed an adnexal carcinoma connected to the epidermis and composed of cystic papillary projections admixed with solid basaloid areas with marked cytologic atypia. The basaloid tumor cells appeared to blend with the squamous component that demonstrated ductal formation, which was highlighted by carcinoembryonic antigen. Tumor cells were reactive for both cytokeratins 5/6 and 7. This case represents SCACP arising from syringocystadenoma papilliferum in the upper arm, with distinct transition to areas of squamous differentiation.

Abstract
Syringocystadenocarcinoma papilliferum is a rare form of adenocarcinoma of the skin. It is the malignant counterpart of syringocystadenoma papilliferum (SCAP). It usually develops on the scalp in a long-standing lesion identified clinically as SCAP. Twelve cases of syringocystadenocarcinoma papilliferum have been reported in literature, with limited information regarding its clinical and histological characteristics. Sarcomatous change in a case of SCAP has not been reported in literature till date to the best of our knowledge. We present the first case of syringocystadenocarcino-sarcoma papilliferum in a middle-aged female with a satellite lesion over the scalp.

Abstract
We report a rare case of giant squamous cell carcinoma of the buttock infiltrated to the rectum. The tumor may have arisen from syringocystadenoma papilliferum. Since there was no sign of metastasis, radical operation including rectal amputation was performed after successful neoadjuvant therapies. Afterwards, the patient has been alive free from disease for 15 months with no lymph node and distant organ metastasis.
