Primary squamous cell carcinoma of the liver associated with hepatolithiasis: A case report

Primary squamous cell carcinoma (SCC) of the liver is rare and reported sporadically. Up to date, only 24 such cases have been reported in the literature. It is associated with hepatic teratoma, congenital cysts, solitary benign non-parasitic hepatic cysts, hepatolithiasis/Caroli’s disease or cirrhosis. We reported a case of primary SCC of the liver associated with multiple intrahepatic cholesterol gallstones. The patient underwent hepatectomy followed by radiotherapy, and has survived for over 19 mo without recurrence.     

Primary squamous cell carcinoma of the stomach: a case report

Primary squamous cell carcinoma of the stomach: a case report with immunohistochemical and molecular biologic studies

Primary squamous cell carcinoma (SCC) of the stomach is an extremely rare tumor and its pathogenesis is still unknown. We report a case of SCC of the stomach in a 69-year-old man. The patient's stomach contained an area of SCC surrounded by squamous metaplasia. To our knowledge, this is the first reported study to have investigated the pathogenesis of this tumor type by immunohistochemistry, liquid hybridization assay for human papilloma virus (HPV) infection, and polymerase chain reaction for Epstein-Barr virus (EBV) infection. These tests yielded proof of EBV infection in surgical specimens of the tumor. Therefore, we suggest that EBV infection may be involved in the pathogenesis of SCC arising in the stomach.     

Primary squamous cell carcinoma of the stomach: a case report and review of the literature

Primary squamous cell carcinoma of the stomach is extremely rare. To date, only 80 cases have been reported. A 65-year-old man with complaints of epigastric pain and cachexia for the past year is presented. He had a tumour with infiltration of the corpus and antrum of the stomach. The tumour was unresectable, and the patient died within 3 months.     

Primary squamous cell carcinoma of the stomach: a case report with a review of Japanese and Western literature

A case of a 75 year-old male with primary squamous cell carcinoma of the stomach is reported. It is extremely rare to see squamous cell carcinoma developing in the stomach, without being accompanied by a component of adenocarcinoma. Up to the present, 18 Japanese and 62 Western cases of this type of carcinoma have been reported in the literature. The origin of this malignancy has not been well elucidated yet and thus, several plausible hypotheses have been proposed. In this presented case, the tumor consisted of only squamous cell carcinoma and the focus of squamous metaplasia was not found histologically in the adjacent mucosa. Therefore, it may be considered that the carcinoma arises from misplaced squamous cell nests of the stomach.     

Primary squamous cell carcinoma of pancreas diagnosed by EUS-FNA： A case report

Squamous cell carcinoma of the pancreas has been sparsely described since the 1940s, and generally has a poor prognosis. Herein, we present a case of primary squamous cell carcinoma of the pancreas with liver metastasis, both confirmed by endoscopic ultrasoundguided fine needle aspiration （EUS-FNA）. To the best of our knowledge, this is the first case report in literature utilizing EUS-FNA for a cell-type specific diagnosis of primary pancreatic squamous cell carcinoma with a liver metastasis.     

Primary adenosquamous carcinoma of the liver: case report

We describe a case of adenosquamous carcinoma of the liver, including treatment for the recurrence. A 67‐year‐old man with prolonged high fever was diagnosed with a mass lesion in the left lobe of the liver seen by imaging studies. That mass lesion was histologically diagnosed as cholangiocarcinoma by needle biopsy. Left hepatic lobectomy was performed, and a tumor was found that measured 8.0 × 7.0 × 6.0 cm. It was a yellowish white solid mass without macroscopic invasion of the intrahepatic bile duct. Histological examination of the resected specimen revealed both adenocarcinoma and squamous cell carcinoma. The postoperative course was uneventful, but abdominal computed tomography 3 months after operation revealed seven masses in the remnant liver. We diagnosed recurrence of the tumor, and intrahepatic arterial infusion of cisplatin and 5‐fluorouracil was begun. A partial remission resulted. Progression‐free survival after chemotherapy lasted 2 months. However, the tumor markers and remnant tumor size increased gradually 9 months after the operation, and he died 14 months after surgery. We also review 41 cases of adenosquamous carcinoma of the liver reported in the Japanese and English language literature, including the present case.     

Primary micropapillary carcinoma of the colon: a case report and literature review

We report a case of micropapillary carcinoma (MPC) of the transverse colon. A 56-year-old woman was admitted to our hospital with hematochezia. A lower gastrointestinal examination revealed an irregular ulcerative tumor of approximately 60 mm diameter with marginal elevation in the transverse colon. Abdominal computed tomography showed multiple swollen lymph nodes. A histological examination of the resected specimen revealed that cancer cells had invaded the subserosa. Microscopically, small papillary cells proliferated with lacuna spaces and the cribriform glandular configuration was observed. Immunohistochemically, the basal surface of the neoplastic cell clusters was diffusely positive for MUC1. No primary tumor was observed except for the colon. Therefore, this tumor was diagnosed as a primary MPC of the colon. Since a colorectal MPC was first reported in 2005, seven case reports and three pathological reviews have been presented in the English literature. MPC has an aggressive behavior with a high incidence of lymphovascular invasion and nodal metastases. We should take intensive chemotherapy for colorectal MPC into account, even if surgical resection is curative.     

Double primary cancer of the esophagus consisting of ectopic gastric mucosa-derived adenocarcinoma and squamous cell carcinoma: a first case report

Most esophageal cancers are either squamous cell carcinomas or Barrett??s mucosa-derived adenocarcinomas. A 64-year-old man with a long history of alcohol drinking and smoking was found to have a tumor in the cervical esophagus on screening esophagography. Subsequent work-up revealed double primary cancer of the esophagus consisting of adenocarcinoma arising from ectopic gastric mucosa in the cervical esophagus and squamous cell carcinoma in the abdominal esophagus. He underwent subtotal esophagectomy. On microscopic examination of the resected specimen, the Ip tumor in the cervical esophagus was confirmed to be an adenocarcinoma derived from ectopic gastric mucosa that had invaded the muscularis mucosa, and the 0-IIb tumor located near the esophagogastric junction was confirmed to be a squamous cell carcinoma that had invaded the proper mucosal layer. No lymph node metastases were noted. Adenocarcinoma from ectopic gastric mucosa is rare, and its coexistence with squamous cell carcinoma is extremely rare.     

Primary squamous cell carcinoma of the liver initially presenting with pseudoachalasia

Pseudoachalasia secondary to primary squamous cell carcinoma (SCC) of the liver is extremely rare and has not been reported until now. Here, we report a unique case of primary SCC of the liver initially presenting with progressive dysphagia along with short periods of significant weight loss. A 58-year-old man initially presented with progressive dysphagia along with significant weight loss over brief periods of time. The radiographic and manometric findings were consistent with achalasia. Subsequent esophagogastroduodenoscopy revealed a moderately dilated esophagus without evidence of neoplasm or organic obstruction. However, firm resistance was encountered while traversing the esophagogastric junction (EGJ), although no mucosal lesion was identified. Due to the clinical suspicion of the presence of a malignant tumor, endoscopic ultrasonography (EUS) and computed tomography scans of the chest and abdomen were obtained. A huge hepatic mass with irregular margins extending to the EGJ was found. EUS-guided fine-needle aspiration was performed, and the mass was diagnosed as a primary SCC of the liver by immunohistochemical staining.     

程序性死亡受体1单抗联合阿帕替尼治疗罕见原发性肝脏鳞状细胞癌1例报告

原发性肝脏鳞状细胞癌(primary squamous cell carcinoma of liver,PSCCL)非常罕见,自从1934年第1例病例被报道以来,仅有70余例相似病例在国内外陆续被报道。目前PSCCL病因不明,恶性程度极高,且无特异性临床表现,明确诊断时患者常已是晚期。因此预后很差,即使手术切除,术后生存时间多不超过1年[1-2]。本院近期收治1例PSCCL患者,并首次应用程序性死亡受体(PD-1)单抗药物联合抗血管靶向药物治疗,取得了较好的疗效。

Intramuscular metastasis of cutaneous squamous cell carcinoma: a case report

Cutaneous squamous cell carcinoma (SCC) is a common cancer. Although most patients with primary cutaneous SCC have an excellent prognosis, for those with metastatic disease, the long-term prognosis is poor. The most common sites of metastasis are regional lymph nodes, lung, liver, brain, skin, and bone. However, metastatic soft tissue SCC from cutaneous lesions is extremely rare, with only two reported cases. We report a case in which the patient had a primary SCC lesion on his left palm in 1986. A second primary SCC on his left forearm was confirmed in 2001, with subsequent metastasis to the proximal muscles and bone invasion in spite of the initial wide excision.
