Abstract
PurposeTo provide more basis for further diagnosis and differentiation for Endocrine Mucin-Producing Sweat Gland Carcinoma (EMPSGC), we offer a case report and a comprehensive review of the epidemiology, immunohistochemical findings, and molecular mechanisms underlying EMPSGC.Case descriptionWe herein present a case of a 70-year-old Chinese male patient who presented with a painless, progressively enlarging skin mass at his right lateral canthus. Histopathological examination revealed solid papillary growth patterns with intracellular mucin, and immunohistochemical staining was positive for Ki-67, P53, EMA, CK7, GATA3, CgA, Syn, INSM1, and AR, confirming the diagnosis of EMPSGC. Literature revealed that EMPSGC is a rare, low-grade malignant tumor with neuroendocrine differentiation. Key immunohistochemical markers include CK7, GATA-3, and INSM1, which aid in diagnosis. Hormone receptors such as ER, PgR, and AR are frequently expressed. The recurrence risk ranges from 7.11% to 14.3%, with rare cases of metastasis to the parotid gland, lungs, and skeletal system. Following surgical resection and subsequent pathological examination, the lesion was diagnosed as EMPSGC. In this report, we delineate the clinical presentation, Hematoxylin and eosin (H&E) staining features, and immunohistochemical characteristics of this case. We also conduct a literature review to enhance the understanding of EMPSGC.ConclusionEMPSGC is a relatively rare type of eyelid tumor in ophthalmic diagnosis and treatment. However, it poses a significant risk of misdiagnosis with other ocular tumors. Any eyelid mass demands attention, and necessitates prompt resection followed by intraoperative and/or postoperative pathological examination to avoid misdiagnose and poor prognosis.

Abstract
The patient presented with a malignant tumour that was a slow-growing, painless lesion on the lower eyelid. The main differential diagnoses are cutaneous metastasis of adenocarcinoma and sebaceous carcinoma of the eyelid. They must be ruled out. As immunohistochemistry does not always provide a definitive diagnosis, an extended investigation must be carried out.

Abstract
Sweat-gland carcinoma with neuroendocrine differentiation (SCAND) was recently proposed as a new cutaneous adnexal neoplasm with neuroendocrine differentiation; however, its genetics are not well known. Herein, we performed clinicopathologic and genetic analyses of 13 SCAND cases and 5 control cases of endocrine mucin-producing sweat gland carcinoma (EMPSGC). The SCAND group included 11 males and 2 females with a median age of 68 years (range, 50 to 80 y). All SCAND lesions occurred in the ventral trunk or genital area. Of the 13 SCAND cases, 9 and 5 exhibited lymph node and distant metastases, respectively. Three (23.1%) patients with SCAND died of the disease. In contrast, neither metastasis nor mortality was confirmed in the EMPSGC cases. Immunoexpression of the androgen receptor, c-Myb, and MUC2 was limited in SCAND, whereas EMPSGC frequently expressed these immunomarkers. GATA3 P409Afs*99 extension mutations were detected in 7 (53.8%) of the 13 SCAND cases, using Sanger or panel sequencing. All 7 SCAND cases with GATA3 mutations were located in the genital, inguinal, or lower abdominal regions, whereas 5 of the other 6 SCAND cases were located in the anterior upper to mid-trunk. No GATA3 mutations were detected in the EMPSGC cases (0/5, 0%). These clinicopathologic and genetic findings support SCAND as a tumor entity distinguishable from EMPSGC. In addition, the characteristic frameshift extension mutations in GATA3 contribute to the establishment of the tumor-type concept of SCAND.

Abstract
Endocrine mucin-producing sweat gland carcinoma (EMPSGC) is a rare, low-grade neuroendocrine neoplasm previously believed to be indolent in nature. There have only previously been six reported cases of metastases and none of thoracic structures. This case shows a metastatic EMPSGC in a 72-year-old male with a complex oncologic history and is the first reported case of metastases to the lung. As increased recognition of this entity continues to grow, it is important to consider it as part of the differential in mucinous and/or neuroendocrine neoplasms for appropriate management. This case adds to the oncologic literature by demonstrating a rare cutaneous neoplasm and emphasizing its metastatic potential.

A case report and review of the literature. EXCLI JOURNAL 2023; 22:992-1011.

Abstract
We report on an aggressive, infiltrating, metastatic, and ultimately lethal basaloid type of carcinoma arising shortly after an mRNA vaccination for COVID-19. The wife of the patient, since deceased, gave the consent for publishing the case. The malignancy was of cutaneous origin and the case showed symptoms consistent with Bell's palsy and trigeminal neuralgia beginning four days post-vaccination (right side head temporal pain). The temporal pain was suggestive for inflammation and impairment of T cell immune activation. Magnetic Resonance Imaging (MRI) showed a vascular loop on the left lateral aspect of the 5th cranial root exit of cerebellopontine angle constituting presumably a normal variant and was considered as an unrelated factor to the right-sided palsy and pain symptoms that corresponded to cranial nerves V (trigeminal nerve) and VII (facial nerve). In this study we describe all aspects of this case and discuss possible causal links between the rapid emergence of this metastatic cancer and mRNA vaccination. We place this within the context of multiple immune impairments potentially related to the mRNA injections that would be expected to potentiate more aggressive presentation and progression of cancer. The type of malignancy we describe suggests a population risk for occurrence of a large variety of relatively common basaloid phenotype cancer cells, which may have the potential for metastatic disease. This can be avoidable with early diagnosis and adequate treatment. Since facial paralysis/pain is one of the more common adverse neurological events following mRNA injection, careful inspection of cutaneous/soft tissue should be conducted to rule out malignancy. An extensive literature review is carried out, in order to elucidate the toxicity of mRNA vaccination that may have led to the death of this patient. Preventive and precise routine clinical investigations can potentially avoid future mortalities. See also Figure 1(Fig. 1).

Endocrine Mucin-Producing Sweat Gland Carcinoma: Case Presentation with a Comprehensive Review of the Literature. Dermatopathology (Basel) 2023; 10:266-280. [PMID: 37754277 PMCID: PMC10529628 DOI: 10.3390/dermatopathology10030035] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/25/2023] [Revised: 08/22/2023] [Accepted: 08/29/2023] [Indexed: 09/28/2023] Open
Abstract
(1) Background: Endocrine Mucin-Producing Sweat Gland Carcinoma (EMPSGC) is a rare, low-grade, neuroendocrine-differentiated, cutaneous adnexal tumor, officially recognized by the World Health Organization (WHO) Skin Tumors Classification in 2018 as a separate entity and homologue of endocrine ductal carcinoma in situ (eDCIS)/solid papillary carcinoma of the breast. Although it is more frequent in the female sex, between 60 and 70 years old, in the peri-orbital region, EMPSGC has also been described in the male sex, in subjects under 60 and over 80, and in extra-eyelid localizations (cheek, temple, scalp), but also in extra-facial localizations (chest and scrotum). (2) Methods: We present the clinical case of a 71-year-old woman with an undated lesion of the scalp, which presented as a nodule, skin-colored, and 2.5 cm in maximum diameter. We also conduct a comprehensive literature review from 1997 to the end of 2022, consulting PubMed, Scopus, Web of Science (WoS), and Google Scholar using the following keywords: "Endocrine mucin-producing sweat gland carcinoma" and/or "EMPSGC" and/or "skin" and "cutaneous neoplasms". In addition, we followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. A total of 253 patients were recorded; 146 were females (57.7%) and 107 were males (42.2%). The vast majority of the lesions were in the eyelids (peri-ocular region), and only a minority of cases involved the cheeks, supra-auricular, retro-auricular, and occipital region, with very rare cases in the scalp, to which the present is also added. (4) Conclusions: The morphological and immunophenotypical features are essential both for the correct diagnosis and to be able to classify this lesion among the corresponding eDCIS/solid papillary carcinoma of the breast, with neuroendocrine differentiation. Recent papers have attempted to shed light on the molecular features of EMPSGC, and much remains to be conducted in the attempt to subtype the molecular profiles of these entities. Future studies with large case series, and especially with molecular biology techniques, will be needed to further add information about EMPSGC and its relationship in the PCMC spectrum.

Abstract
Background. Metastasis to parotid gland occurs mostly from skin cancers of the head and neck region. Metastatic neuroendocrine tumors to the parotid gland are rare and not well studied so far. In this study, we undertook a retrospective review of secondary neuroendocrine tumors of the parotid diagnosed in our institution. The most common entities, primary tumor locations, their clinical presentations and histopathological features were analyzed. Methods. Cases of secondary neuroendocrine tumors to parotid diagnosed from August 1995 to Jan 2021 were retrieved from our institution's pathology databases, and their clinicopathological features were reviewed. Results. About 29% (120 of 420 cases) of parotid neoplasms were malignant, including 70 cases of parotid primary malignant tumors and 50 cases of metastases to parotid glands. Among metastatic tumors to the parotid glands, squamous cell carcinoma and melanoma of the head and neck region together accounted for about 78% of the cases. Only 11 of 50 metastatic tumors to the parotid were neuroendocrine carcinomas (22%). The most common primaries were poorly differentiated neuroendocrine carcinoma of lung (5 of 11 cases), including 4 cases of small cell carcinoma and one case of large cell neuroendocrine carcinoma. The second most common secondary tumor was Merkel cell carcinoma (4 of 11 cases, 36%) including one case of direct invasion from overlying skin. Medullary carcinoma of the thyroid comprised the rest of the metastases to the parotid (2 of 11 cases, 18%). Conclusion. Our results show that metastatic neuroendocrine carcinomas to the parotid gland account for about 22% of all metastatic tumors to the organ. Lung is the most common primary neuroendocrine carcinoma location. It is not uncommon for metastatic neuroendocrine carcinoma to present as the first sign of systemic clinical manifestation. Merkel cell carcinoma is the second most common entity that metastasizes to parotid, followed by medullary carcinoma of the thyroid.

Abstract
ABSTRACT Primary cutaneous mucinous carcinoma is a rare, indolent malignancy with a debated history regarding cell of origin. Recurrence is rare but has been documented in up to a third of cases. Recent literature reviews have recognized 2 possible subtypes-neuroendocrine and nonneuroendocrine- with different possible prognostic implications for patients. We describe a case of recurrent primary cutaneous mucinous carcinoma in a 50-year-old man with subtle neuroendocrine features not initially recognized on routine H&E staining but highlighted by immunohistochemical studies. We underscore the importance of immunohistochemical use in these rare cases and emphasize that awareness of these neuroendocrine and nonneuroendocrine subtypes is essential for a complete diagnosis.

Abstract
BACKGROUND Metastases account for 6-25% of parotid tumors, often presenting dilemmas in their diagnosis. METHODS Parotid metastases diagnosed on histology/cytology were retrieved. MUC2, MUC5AC, androgen receptor immunohistochemistry was performed in select cases. RESULTS Fifty-one samples were identified from 42 patients, including 14 aspirates, 7 biopsies and 30 parotidectomies. Previous history was available in 17 cases, 13 parotidectomies accompanied excision of the primary, and relevant clinical data was unavailable for 12 patients. Majority (81%) had head and neck primaries; eye and ocular adnexa were the commonest subsite (52.4%), and sebaceous carcinoma the commonest histology (33%). When history was unavailable, most metastases were initially diagnosed as poorly differentiated carcinoma/malignant tumor, or mucoepidermoid carcinoma on cytology. CONCLUSIONS Intraparotid metastases encompass a wide spectrum, often mimicking primary salivary gland neoplasms, particularly on limited samples. Metastases should be considered when histological/cytological features are unusual; detailed clinical information and ancillary techniques aid in arriving at an accurate diagnosis.
