[PMID: 36398700 DOI: 10.1080/01676830.2022.2145613] [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: 09/21/2022] [Accepted: 11/02/2022] [Indexed: 06/16/2023]
Abstract
A 47-year-old female developed a reddish swelling of the right medial canthus over 3 months. On examination, a red, firm mass, involving the right medial canthal and extending into the inferior fornix was present and the globe was displaced upwards and inwards. A staging MRI scan confirmed a lacrimal sac lesion with anterior orbit extension. After an equivocal biopsy, the patient underwent debulking surgery. Histology showed a lacrimal sac invasive adenosquamous carcinoma, comprising poorly differentiated squamous carcinoma and invasive adenocarcinoma areas arranged in a tubulo-glandular pattern. The adenocarcinoma harboured numerous cilia. p16 showed block positivity of both components and micro-dissected tissue from both areas showed the presence of HPV16 DNA by PCR. This is the first description of ciliated adenosquamous carcinoma of the lacrimal sac and this finding is placed into the context of what is known about ciliated head and neck adenosquamous carcinomas and the role of high-risk HPV.

Xin G, Song N, Jiang K. Esophageal squamous cell carcinoma transformed into neuroendocrine carcinoma after neoadjuvant immunochemotherapy: A case report. Oncol Lett 2024; 27:184. [PMID: 38476207 PMCID: PMC10928968 DOI: 10.3892/ol.2024.14317] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/24/2023] [Accepted: 02/13/2024] [Indexed: 03/14/2024] Open
Abstract
Immunotherapy provides durable responses for locally advanced esophageal carcinoma clinical therapy in numerous patients. However, the mechanisms of resistance to immunotherapy have not been elucidated. The phenomenon of the histological transformation of non-small cell lung cancer to small cell lung cancer resulting in resistance to immune checkpoint inhibitors (ICIs) has been reported. It remains unclear whether ICIs or chemotherapy could cause a similar transformation from esophageal squamous cell carcinoma (ESCC) to esophageal neuroendocrine carcinoma (ENEC). The present study report the case of a patient initially diagnosed with stage II ESCC who underwent radical surgery after three cycles of neoadjuvant therapy with cisplatin, albumin bound paclitaxel and ICIs. Immunohistochemical staining confirmed the absence of the SCC component and the presence of the NEC component, with negativity for CK5/6 and tumor protein p40, but positive expression of tumor protein p53, pan-cytokeratin, synaptophysin and CD56. The patient was followed up for 5 months with no treatment or postoperative complications. In conclusion, histological transformation to ENEC is a potential mechanism of acquired resistance to ICIs in ESCC. Prospective larger studies are warranted to further characterize ESCC-to-NEC transformation on use of ICIs.

Esophageal squamous cell carcinoma with basaloid features are genetically and prognostically similar to conventional squamous cell carcinoma. Mod Pathol 2022; 35:1247-1253. [PMID: 35351978 DOI: 10.1038/s41379-022-01060-4] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/11/2021] [Revised: 02/18/2022] [Accepted: 02/18/2022] [Indexed: 11/08/2022]
Abstract
We compared clinicopathologic and molecular features of esophageal squamous cell carcinoma (SCC) with basaloid features to conventional SCC using surgical resections of treatment naïve esophageal carcinomas and cases available from the TCGA database. Twenty-two cases of SCC with basaloid features were identified in the Mass General Brigham pathology archives, including 9 cases with pure basaloid morphology and 13 cases with mixed other features such as conventional well- or poorly differentiated areas or sarcomatoid areas. Thirty-eight cases of conventional SCC matched by tumor stage were used as controls. HPV infection status was tested by p16 immunohistochemistry and HPV mRNA ISH. Digital slides for 94 cases of esophageal SCC from TCGA found in the Genomic Data Commons (GDC) Data Portal were reviewed. Five cases of SCC with basaloid features were identified. Genomic profiles of SCC with basaloid features were compared to the rest of 89 SCCs without basaloid features. In addition, eight tumor sections from six patients selected from our cohort underwent in-house molecular profiling. Compared to conventional SCC, SCC with basaloid features were more frequently associated with diffuse or multifocal squamous dysplasia (p < 0.001). P16 IHC was positive in 2/13 cases, whereas HPV mRNA ISH was negative in 17/17 cases (including both p16-positive cases). SCC with basaloid features and conventional SCC from TCGA showed similar rates of TP53 mutations, CDKN2A/B deletions, and CCDN1 amplifications. TP53 variants were identified in all in-house samples that had sufficient coverage. Survival analyses between SCC with basaloid features versus conventional SCC (matched for tumor stage) did not reveal any statistically significant differences. In conclusion, esophageal SCC with basaloid features has similar survival and genomic alterations to those of conventional SCC, are more frequently associated with diffuse or multifocal dysplasia, and are not associated with HPV (high-risk strains) infection.

Subcutaneous soft tissue metastases from esophageal squamous cell carcinoma with neuroendocrine differentiation: Case report and literature review. Front Oncol 2022; 12:895189.

Abstract
BackgroundEsophageal squamous cell carcinoma is the predominant subtype of esophageal cancer in China and so differs from presentations in Western countries. Common metastatic locations of esophageal cancer include the liver, lung, bone, and brain. In contrast, metastases in subcutaneous soft tissue are exceedingly rare.Case presentationWe present the experience of a 57-year-old man with a complaint of hand and leg dysfunction on the right side. He had a past medical history of esophageal squamous cell carcinoma. Further imaging workup revealed a solitary brain metastasis, thickening of the esophageal wall, swollen lymph nodes in the mediastinum, and right adrenal gland metastasis. Gamma knife radiosurgery of the brain metastasis and intensity-modulated radiotherapy of the esophagus and lymph nodes were administered. After 1.5 months, he was admitted to our hospital again, and nodules were identified in the anterior abdominal wall and left posterior chest wall. Ultrasound, CT, and radical excision of the abdominal wall mass were undertaken and revealed metastatic squamous cell carcinoma with neuroendocrine differentiation. We administered immunotherapy followed by targeted therapy. A PET/CT scan was performed to identify other organ metastases; the scan revealed multiple areas of fluorodeoxyglucose uptake and foci in the esophagus, lung, liver, bone, and right adrenal gland; and in various lymph nodes. In addition, an intensely hypermetabolic lesion was localized in the left posterior thorax.ConclusionThis case highlights the diagnosis and treatment of uncommon metastases of esophageal squamous cell carcinoma. We hope that our clinical experience provides insights into these uncommon metastases.

Abstract
Basaloid squamous cell carcinoma of the esophagus is rare and generally detected at advanced stage, and its prognosis is poorer than that of conventional esophageal squamous cell carcinoma. Therefore, detection at the early stage is crucial for patient survival. We experienced an elevated esophageal basaloid squamous cell carcinoma presenting as a subepithelial tumor-like lesion. Although the lesion needed to be differentiated from subepithelial tumor, we diagnosed it as early stage and treated with endoscopic submucosal dissection. We report the macroscopic and microscopic findings of basaloid carcinoma through this case along with a review of the relevant literature.
